Socio-Economic Conditions of Small-Scale Hilsa Fishers in the Meghna River Estuary of Chandpur, Bangladesh

Hilsa fish (Tenualosa ilisha) have become an essential factor behind the well-being of the fishing community, giving fishers their identity as a source of cultural heritage. A field survey was conducted to understand the socio-economic conditions of hilsa fishers at the Meghna river estuary of Chandpur District using well-structured questionnaire interviews (N = 250) with hilsa fishers. The survey revealed that fishers’ livelihoods and living conditions were still below average due to low literacy levels, lack of professional skills, and low incomes. More than two-thirds of the fishers were entirely dependent on hilsa fishing, while more than one-third had between 11 and 20 years of fishing experience. More than two-thirds of the fishers did not have an alternative occupation during ban periods, and the incentives provided by the government were not adequately received by half of the fishers. Fishers were divided into three groups according to their dependence on hilsa fishing. Significant differences were found between these groups in terms of the age of fishers, annual income from fishing, and annual fishing activity days. Therefore, the government, Fisheries cooperatives, NGOs, and other relevant organizations must unite to support fishers for sustainable management.


Introduction
Small-scale fisheries are an essential and valuable element of global fisheries and play a crucial role in meeting the basic needs of millions of people worldwide in both developed and developing countries [1]. This sector offers many benefits, including economic growth, food, and nutrition security, employment, income for millions of people, and resilience to poverty, particularly for many low-income countries [2]. Recent estimates have shown that approximately 36 million (97%) of the world's fishers are in developing countries. In comparison, approximately 107 million (88%) of the world's fisheries and fish trade workers are employed in the small-scale fishing industry [3]. SSFs provide animal protein and livelihood to 11% of the total population but face risks due to multifactorial issues related to indiscriminate fishing, unregulated fishers and efforts, illegal fishing nets (fine-mesh monofilament nets), conflict over resources, and climatic variability. This, in turn, has led to fisheries-dependent livelihoods being vulnerable and ultimately unsustainable. Moreover, despite the vital role SSFs play in national and local the Meghna river estuary of Chandpur, Bangladesh. Using the resource users' perspective, the study will contribute to more profound insights into the social-ecological aspects of small-scale hilsa fishers in the Meghna River. Furthermore, the study's findings will contribute to a knowledge base for new, practical, and fairer management approaches.

Selection of the Study Areas
Using a comparative case study approach, the livelihoods of small-scale hilsa fishers in the Meghna river estuary were assessed ( Figure 1). The study was carried out in two Upazilas of the Chandpur district, named Chandpur Sadar and Haimchar, and four villages were selected to represent different socio-religious patterns, Anandabazar, Charvanga, Charvoirovi, and Bishnupur (Tables 1 and 2).   10 20 The author also discussed with personnel of locally active NGOs (CNRS, ASA, BRAC, and SAJIDA), World Fish Center, DoF, local school teachers, fish traders, and community members to obtain an impartial impression about fishing villages.

Data Collection Methods
Primary data were collected using qualitative methods, including interviews, focus group discussions (FGDs), and participatory observation from June 2018 to December 2018. Using a semi-structured questionnaire, in-depth interviews (N = 250) were conducted at two Upazilas, Chandpur Sadar, and Haimchar, to gather the necessary information. Interviews were held at fish landing sites, fishermen's houses, and local fish markets and shops, where fishermen spend their time in various activities such as loading and unloading fish, repairing nets and boats etc. Secondary data such as fisheries production data were from relevant published books, scholarly articles, and relevant literature through an online search.

Participant Observation
Information about the characteristics and fishing activities of hilsa fishers was collected through participant observation. Fieldwork in the selected fishing village began with an observation of the fishermen's lives and fishing methods. This observation appeared to be the most useful, practical, and understandable way of learning directly and confidently in a natural or social setting by immersing people's livelihood dynamics, motives, values, beliefs, interests, and local knowledge in the local cultural environment.

Semi-Structured Key Informant Interviews
Open-ended interviews with a semi-structured questionnaire were conducted with a duration of 30-45 min, with the key knowledgeable people in the communities, Fisheries Scientific Officers, and relevant NGO workers, to gather information on issues of coping strategies, livelihood diversities, fisheries resources, gear, indigenous knowledge, conflicts, changes in fishing regulations, local institutions, and other factors.

Focus Group Discussion (FGD)
In the study areas, 10 FGDs were conducted with 5-7 participants, each lasting up to 1 h (Table 3). FGD was effectively used to collect and validate production relations, livelihood changes, coping actions, diversity, rituals, social and economic institutions, and indigenous knowledge.

Data Analysis
The collected information from the survey was accumulated, grouped, and interpreted according to the objective and parameters. The collected data were then organized, summarized, and followed by graphical analyzes during this study. Finally, all the quantitative data obtained from interviews were analyzed using SPPSS version 22.

Socio-Economic Characteristics of the Fishers
People belonging to fishing communities in the coastal region of Bangladesh are economically vulnerable in terms of earnings and employment. Most hilsa fishers are so poor that they cannot renew their boats to fish in the aquatic environment. The survey was conducted on 250 hilsa fishers who were generally engaged in fishing, of which 240 (96%) were male (Table 4). In general, it was observed that women were engaged in domestic activities and were not allowed to go out for large-scale fishing due to social and security problems.
The results showed that 41% of the fishers were in the 26-30 age group, more than a third (38%) of the participants were in the 40-60 age range, and only a few (9%) of the fishers were in the age group of (>60 years). Fishers reported to prefer nuclear families (head of household, with spouse and children) rather than joint families (head of household, spouse and children, father, mother, brothers, and sisters) due to household expenses.
One of the most productive assets of the people living in the villages is to have agricultural land. The study revealed that 57% of the fishers had no land, 33% owned 5-10 decimals, and 10% had more than 10 decimals. The present study revealed that 79% of the fishers were entirely dependent on fisheries, 14% were partially dependent on fisheries, and only 7% were non-dependent fishers ( Table 4). The fishing experience of the fishers was collected through in-depth interviews with fishers.
According to the survey, 35% of people have 11 to 20 years of experience, and few have more than 40 years of fishing experience. For most households (47%), monthly income was 5000 to 10,000 BDT (1 USD=85.12 BDT), while 24% of fishers' income was less than 5000 BDT per month. On the contrary, 20% of fishers monthly income was 10,000-20,000 BDT, and only 9% of fishers reported monthly income of over 20,000 BDT. The pattern of the housing materials indicates the people's standard of living, their social status, and financial capacity. More than half (53%) of the fishers' houses were made of tin and wood, while the remaining fishers' houses were made with a straw roof and bamboo fences (24%), semi pacca (18%), and pacca (5%).
The sanitary conditions of the fishers were deplorable. Only 13% of fishers' families use sanitary toilets made of brick, while more than half of the fishers (54%) use toilets made of sand (Katcha). From the study sites, more than half of the fishers (57%) received health services from the hospital, whereas one-third of the fishers (30%) were dependent on unlicensed village doctors.
Credit access facilities for the small-scale hilsa fishers were minimal. Therefore, it has been perceived that most fishers rely on informal sources of financing to meet the expenses of their enterprises due to low incomes and limited personal savings. The survey found that 60% of the hilsa fishers borrowed money from NGOs, 20% from money lenders, 16% from relatives and neighbors, and only 4% from banks. In addition, it was found that 35% of the fishers received sufficient incentives from the government, while 65% reported that they did not receive sufficient incentives during the ban season.

Food and Nutrition
The major food items consumed by the hilsa fishers were fish, meat, dal, egg, and vegetables. It was found that the monthly intake of fish was higher (55%) than the other food items ( Figure 2). Fishermen reported that they kept some fish for themselves as food while fishing and selling fish. During the fishing ban period, the poor fishers suffered from food shortages. A total 28% of fishers reported that to withstand this situation, they were compelled to reduce their meal frequency to two meals per day and consume less expensive food items (Table  5). They mainly depended on vegetables during the banning season, and their fish consumption was reduced to 0-1 days per week from 5-6 days per week (Table 5). Therefore, reducing meal frequency and fish consumption reflects low income levels and a lack of alternative livelihood opportunities during the ban season.

Fishing Crafts, Engine Capacity, and License Availability
The main crafts operating on the Meghna River to catch hilsa fish were small mechanized and non-mechanized boats. The study revealed that 85% of fishers used mechanized boats and the rest (15%) used non-mechanized boats to catch hilsa fish (Table 6). In addition, mechanized boats went to extended areas for 3, 5, or 7 days (mostly gone in 3 days), depending on their storage and carrying capacity, while non-mechanized boats went to nearby areas.
It has been found that more than one third of the fishers (41%) in the study area used boats between 20-30 HP for hilsa fishing (Table 6). At the same time, fishermen reported that boats with 30-40 horsepower engines were used only for long-term fishing and only when there was a shortage of fishermen. Furthermore, fishers stated that they need a lower storage capacity boat for short trips (usually from 6 am to 5 pm or 6 pm). On the other hand, for long trips (usually 3 to 7 days), they need boats with higher storage capacity to catch hilsa fish. It is found that 30% of fishers have no license while the rest, 70%, have a license for hilsa fishing (Table 6). Although a license is crucial for hilsa fishing in both riverside areas in developed countries, there is no essential obligation for hilsa fishing in Bangladesh.

Fishing Gears Used for Hilsa Fishing
The nets used in hilsa fishing were of different sizes depending on the fishing boats used for catching fish. The use of fishing gear also varied from season to season, depending on the availability of fish. The nets used primarily for hilsa fishing in the study areas were the Current Jal (Gill net), Jagat Ber Jal, Ber Jal (Seine net), Chandi jal (Gill net), Gulti Jal (Seine net), Dora Jal (Gill net) ( Table 7).

Total Hilsa Production of the Country vs. Hilsa Production of Chandpur
The given line chart represents the total fish production of the country versus total hilsa production versus hilsa production of Chandpur. Hilsa production in Chandpur was 14

Hilsa Production Trends
In 1999-00 the total production of hilsa was 2.19 lakh metric tons, and in the following years (2001-02) the production increased and reached up to 0.220 million MT. Afterwards, a significant fall in the production occurred in 2002-03 (0.199 million MT). Therefore, it was surprising that after the 2003-04 financial year, every hilsa production rose at a significant number, and at last, in 2016-17, it went to 0.4966 million MT (Figure 3). Hilsa fish production trends have gradually increased from year to year, as shown in Table 8. The highest production was achieved in 2019-20 with 532,795 tons, an increase index number of production of 1.92 compared to the base year (2005-06) ( Table 8).
During the study, it turned out that hilsa production increased after increased management efforts (Figure 4). Production was comparatively lower from 2005-06 to 2006-07 as only sanctuary management was done. Later, production increased, and small incentives were imposed due to new management approaches such as ban periods. In 2009-10, the first year of a strict ban period, a full incentive package such as 30 kg m-1h h-1 VGF (US) was distributed for four months, and as needed, AIGA incentives were distributed to fishers in the production areas. This increased by 13% with increasing index number of production 1.13. After this incentive, hilsa fish production has gradually increased, and the production trend has become relatively high year by year. Therefore, hilsa fish pro-

Perceived Drivers and Pressures in Hilsa Fishing
The main driving forces for less catching by fishers and the changes in the livelihood of the fishers are the use of illegal fishing practices, huge catch of jatka and brood hilsa, industrial pollution, heavy siltation that hinder the migration of hilsa, fishing ban season, use of destructive fishing gear, and violation of rules and regulation particularly in the prohibition period ( Figure 5).
. Figure 5. Perceived drivers and pressures in hilsa fishing.

Fishers Groups According to the Dependence on the Profession
The hilsa fishers (i.e., persons having a professional fishing license) were categorized into three groups with reference to their dependence on fisheries. The majority (72.4%) of the hilsa fishers interviewed belong to Group C (fully dependent fishers), minority (20%) were categorized in Group B (partially dependent fishers), and a further minority (7.6%) were categorized in Group A (non-dependent fishers) ( Table 9) Table 9 showed the number of hilsa fishers belonging to each dependent group by prefecture. Group A was more prominent in some prefectures of Ananda Bazaar (52), but was less numerous at about 8 and 4 in another group. This deviation is due to the presence of large-scale fishing-related activities. The most important part of the other three areas of study was Group A, not B and C.

The Mean and Standard Deviation of the Dependence Group
People who are not dependent on fishing are classified in Group A, in this group, the minimum annual income of the fishers was less than 1 lakh (BDT), and the maximum is 180,000 (BDT) (1USD=85.12BDT) ( Table 10). Fishers used to fish from 150 to 235 days annually, with a minimum daily income of 250 (BDT) and a maximum of 800 (BDT) for fishers. Fishers said that a single fishing trip per day takes from half an hour to a maximum of four hours. On the other hand, the duration of the voyage per fishing trip lasts from a minimum of 2 to a maximum of 4 h, while the duration of fishing lasts from a minimum of 4 h to a maximum of 10 h (Table 10).
Fishers who are partially dependent on fishing are classified in Group B, where their minimum annual income was more than 1 lakh (BDT), and the maximum was 288,000 (BDT). Duration of a single fishing trip takes half an hour to maximum of four hours while the duration of voyage per fishing trip takes minimum 2 h to maximum 4 h, and the duration of fishing takes minimum 4 h to maximum 10 h in a day (Table 10).
Fishers wholly dependent on fishing are categorized in Group C, where their minimum annual income was more than 1 lakh (BDT), and the maximum was 234,000 (BDT). This group were reported to fish for at least 150 days to a maximum of 350 days, with a minimum daily income of 250 (BDT) to maximum of 650 (BDT). This group also said it would take half an hour to a maximum of 6 h to prepare for a fishing trip, where the duration of the fishing trip for each fisher would take 2-5 h (Table 10).  Tables 11 and 12 show the average annual income and activity days per age class for the fisher dependence groups. There was no significant difference in the annual income from fisheries between the age groups, while there was a significant difference between the different dependence groups, as stated before. The income from fisheries follows the same aspect, although it has some important deviations.

The Relation between Fishers Dependence Group & Annual Income from Fisheries
The chi-square test shows that the annual income from fisheries in the three dependent groups is non-significant (p-value 0.360). Annual income from all fisheries is divided into 4 types. Less than or equal to 1 lakh, Category 1 represents income from 100,001 to 1.5 lakh, 2 represents the range between 150,001 to 2 lakh, 3 represents the range between 200,001 to 2.5 lakh. Most people who are not dependent on fishing were in the category 1(13) income range where the income was 100,001 to 1.5 lakhs per year, while the highest income range of non-dependent fishers was 150,001 to 2 lakhs per year. Partially dependent fishers and wholly dependent fishers also showed the same statistics with the maximum in Category 1. The result showed that the highest income of partially dependent fishers is 250,001 to 3 lakhs, while the highest income of wholly dependent fishers was 200,001 to 2.5 lakh (Table 13).

The Kruskal Wallis Test
The Kruskal-Wallis test was used to evaluate differences among categories concerning the three dependent groups. The Kruskal-Wallis test illustrates that the age of hilsa fishers, annual income from all sources, and annual days of activity are significant. For example, the chi-square statistics for fisherman's age was 41.402, annual income from all sources was 102.535, and annual days of activity was 43.582 (Table 14). On the other hand, vessel length, vessel age, annual income from fisheries, income per fishing day, duration of preparation per fishing trip, duration of voyage per fishing trip, and duration of fishing per fishing trip are non-significant.

Analysis of Variance Test
The present results (Table 15) depict that vessel length, vessel age, annual income from fisheries, income per fishing day, duration of preparation per fishing trip, and duration of voyage per fishing trip were found insignificant, whereas age of fisherman, and annual days of activity were found significant.

Discussion
Small-scale fisheries are a sector that is heterogeneous at various levels (spatial, temporal, tool diversity), has different social and cultural importance, has its own characteristics, and is very difficult to define [26]. Small-scale fishers in Bangladesh are among the most vulnerable communities in society, living with extreme stratification, discrimination, social exclusion, and economic domination [19]. Their livelihoods and living conditions are still below average in the adjacent Padma and Meghna Rivers. The available data and the findings of this study show that some features of small-scale fisheries in Chandpur make them completely different from the average national status and present significant challenges to management. These are the number of small-scale fishers and boats and the various levels of fishing activities ( Table 6). As a result, there is a high level of heterogeneity in the level of occupational dependence, as confirmed by current findings and previous studies [26].
The socio-economic status of small-scale hilsa fishers in this study shows that fishers have lower education levels, lower incomes, lower purchasing power, and limited basic facilities than the national average ( Table 4). Most of the fishers were landless, poor, and dependent on fishing for their livelihoods (Table 4). For example, the study found that 31% of fishers lived in joint families, and only 69% lived with nuclear families. In contrast, the average number of members of a nuclear family was 4.17 per household, and the average size of the joint family was 6.22 per household. On the contrary, the average family members were below the national average of 5.6 persons per household in the single-family case. The findings of these studies are consistent with the study of [27], where the authors stated that due to poverty and daily expenses, most community members prefer to have a nuclear family rather than a joint family.
Housing construction materials, availability of sanitary facilities, access to safe drinking water and food are considered units of measurement of peoples' standard of living and an indicator of a country's socio-economic status. It was observed that (53%) of housing structures were made of tin and wood, and the rest were katcha, semi pacca, and pacca. The health facilities of fishers in the study area were insufficient. Although there was one Upazila hospital in the study area, the health facilities used by the fishers were not satisfactory. Fishers often sought health advice from the unskilled, unprofessional village charlatan doctor and Kobiraj. This study was more or less related to [28], who stated that the health services of the Dhaleshwari River fishing community were received from 17.14% Kobiraj, 65.71% village charlatan doctors, 14.29% Upazila health complex, and 2.86% MBBS doctors.
Fishers having access to water sources were either dependent on tube well water, neighbors' tube wells, or sometimes on the river. The study area found that about 50% of the fishers used their tube-well water for drinking, and the latter half used their neighbors' water or sometimes river water for drinking purposes. Reference [24] reported that the great majority (58.25%) of lower Meghna river basin hilsa fishers used government tubewell and the remaining part used their own (15%) and neighbors' (26.75%) tube-wells to collect drinking water which is more or less similar to the present study.
Fishers occupy a lower position in society due to their weak economic capacity [13], limited skills, and options for living. Due to their limited occupational skills, they cannot easily convert to other occupations. Therefore, they find it difficult to obtain alternative income-generating activities during fishing ban periods and suffer a lot. In order to support the fishers and improve the socio-economic situation of the hilsa fishers, the Government of Bangladesh has implemented the food aid program during the fish ban period for fishing communities (covering 187,000 households). As part of the support program, the government distributed some VGF (Vulnerable Group Feeding) cards to poor fishers during the ban season. Through the VGF Card, fishers received 40 kg rice supplements per month for four months during the Jatka fishing restriction period (February-May) [23]. However, this allocation of Government and NGOs is minimal and only supports a small part. More than half of the fishers claimed that they did not receive the total allocation of the VGF card provided by the Government (Table 3). Instead, they get only 30-35 kg of rice per month. The findings are more or less similar to the study of [10,23], which stated that more than half of the fishers did not receive sufficient incentives from the government during the prohibition period due to nepotism and corruption. In addition, the government has also initiated some programs to support alternative income-generating activities such as supplying cash, rickshaw/van, and sewing machines to compensate for the loss of earnings resulting from the fishing ban periods [23].
Fishers were also well-known for the massive destruction of hilsa fish when using the current Jar to collect Jatka from the Meghna river estuary. The use of Gulti jaal, ber jaal also caused a massive loss of jatka and brood hilsa. Most fishers felt that the increase in mechanized boats over the last decade has led to the massive exploitation of the mouth of the Meghna River during the hilsa fishing season. The study of [29] has shown that sewage and industrial wastewater were the primary sources of pollution in the Hooghly River and that metal and pesticide contaminations could negatively impact the health of aquatic organisms. Heavy siltation by sedimentation is also a significant phenomenon in the Meghna river system, and many researchers supported this view.
The fish banning season has a tremendous impact on the livelihoods of small-scale hilsa fishers. As more than two-thirds (79%) of the fishers depend entirely on hilsa fishing, their incomes were about to cease during the prohibition season. They could hardly afford the necessary food and other expenses. Therefore, these fishers had to receive loans from moneylenders/Mohajan/boat owners or from microcredit organizations or neighbors, which led them to an endless debt cycle, leading them to practice illegal fishing methods to have a stable livelihood and repay their loans. In general, boats, nets, and loans are offered by aratders on several terms.
After the introduction of incentive-based management, considering the impact on other management, the production of hilsa increased year by year, and the livelihood status of Jatka or hilsa fishers also improved. Similar opinions have been reported by researchers [14,30,31]. Also, hilsa production increased from 2.777 million tons (2005-06) to 3.51 million tons in 2012-13, rather than decreasing [32]. In addition, production has increased significantly in recent years due to the adoption of different management interventions for this fishery since 2005 [31]. To achieve sustainable production, it is imperative to preserve the jatka while saving the berried hilsa during the peak spawning period for the unabated release of a mature egg [14,32] In recent years, the availability of hilsa in water bodies has decreased significantly due to anthropogenic pressures-the destruction of hilsa juveniles, habitat degradation, indiscriminate capture of hilsa juveniles, and poor enforcement of the net size regulation law [1]. Various law enforcement agencies impose seasonal fishing ban periods, including November-January and March-April. In addition, restrictions are imposed on juvenile hilsa fishing at the six hilsa fish sanctuaries in the Meghna River estuary between November and June. During the two ban periods, hilsa fishers suffered from food and income insecurity, insecure livelihoods, and low living standards that negatively impacted their well-being.
Where resources are scarce and livelihoods uncertain, some activities of fishermen are seen as a necessity rather than a choice [33]. In subsistence fishing, unemployment, poverty, inequality, and economic crises are common reasons for fishermen to not comply with fishing laws. The disadvantaged socio-economic situation of fishermen and the risks they faced in making a living, sometimes dictated the choice of illegal fishing activities that ultimately increases the risk of the serious collapse of fisheries. In [33][34][35], these studies also support this point. Therefore, addressing the threat of collapse should be a priority given the socio-economic dependence of fishing communities, which will have a major impact on the local economy.
Fishermen do not deny the role of authorities and government in compliance with laws and regulations for the long-term sustainability of local fisheries. They understand the problems imposed by socioeconomic expenditures, especially for the livelihoods and well-being of fishermen that arise during prohibition times and put the benefits of this strategy at risk [36]. Fishermen know that banning fish seasons or protecting breeding grounds will limit their activities and jeopardize their income from fishing, but they eventually cope by indiscriminate and illegal fishing practices, catching of brood and juvenile hilsa, use of destructive fishing gears etc. In this case, adequate assistance from the government, microcredit access can play a major role in supporting the fishermen themselves and also in reducing illegal fishing practices.
Complex problems require complex solutions. In this sense, measures such as the prohibition of hilsa hunting alone do not work. Instead, they should rely on other measures adapted to the specific fishing situation. However, conservation efforts will be successful if available income-generating activities in Bangladesh can be implemented [37]. Restricting the ecosystem for a certain period is not seen as a sustainable solution to conserve resources that limit the entry of new fishers and can have long-term negative impacts where significant numbers of people rely on natural resources [38]. Additional measures may be found away from fisheries management in relation to structural issues that require clear policy initiatives, such as corruption, poverty, and unemployment.
Consideration of the socio-economic needs of fishermen is essential, as they cannot forfeit their livelihoods and food security needs because they live on the subsistence level. This ethical and social impact highlights the need to understand the interrelationship between fishermen's socio-economic conditions and their ecological conservation needs. The Government needs to provide adequate assistance, particularly financial support, during the prohibition period and other inevitable crises to continue their profession. In addition, providing adequate assistance to hilsa fishers and identifying authentic, vulnerable hilsa fishers may attract large numbers of non-fishers to participate in hilsa fishing [2]. The Government and affiliated NGOs should organize training programs and skills development seminars with knowledgeable personnel for the skill development of fishers. Policymakers and researchers should address sustainable co-management, aquatic ecosystem development, livelihoods, and vulnerability aspects. Moreover, without excluding the fishers from their responsibility for overexploitation, instead measures must be taken such as training and education of fishers, empowerment, and participation in decision making.

Conclusions
Hilsa, the national fish of Bangladesh, generates employment and income for millions of people in Bangladesh, India, and Myanmar. This study was focused on the livelihood of the hilsa fishers of Chandpur district, Bangladesh. Fishers mainly were poor and neglected in society and were exploited by wealthier classes, mohajan, and aratdar in different ways. Almost 100% of fishers used current jal of which 85% fishers used mechanized boat. Among all fishers 20 to 30 HP of the engine of the mechanized boat had the highest number (41%). The socio-economic condition of the hilsa fishers in the adjacent area was not satisfactory because they were deprived of many amenities. As fishers play an essential role in catching hilsa fish under severely stressful conditions, the government should take some essential steps by providing extra providence (VGF card, soft loan, fishing gears and nets, etc.) off-season to improve their socioeconomic conditions.
