Special Issue Information

Dear Colleagues,

The biodiversity of fish is crucial to maintaining the ecological balance of aquatic ecosystems, providing food and livelihoods for millions of people worldwide, and contributing significantly to the economy. However, fish biodiversity is increasingly under threat from a range of anthropogenic factors that negatively impact fish populations. These threats include habitat destruction, overfishing, pollution, the introduction of invasive species, and climate change. To address these threats, it is essential to have a thorough understanding of the biology and ecology of fish species, which can inform conservation and management efforts.

This special issue is dedicated to exploring various aspects of fish biology and ecology that are critical to conservation and management efforts. For example, reproductive biology is an essential area of study, as understanding the reproductive behavior and biology of fish species can help inform conservation strategies aimed at promoting successful reproduction and recruitment. Feeding habits are also crucial, as changes in prey availability and feeding patterns can significantly affect the survival and growth of fish populations.

Osteology and morphology provide insights into the evolution of fish species and can help inform conservation and management strategies. The length-weight relationship and growth pattern of fish species are also important, as they provide critical information on the life history of different fish species.

Overall, the information collected in this special issue will be essential for the development of effective conservation and management strategies for fish populations and will contribute significantly to our understanding of fish biology and ecology.

The management of water resources is a complex issue, and the conservation of fish and fishery resources is a growing challenge given the increase in the number of hydroelectric projects in Brazilian river basins. This study describes the fragmentation of the Tocantins–Araguaia River Basin resulting from the installation of hydroelectric plants in operation and planned by the electricity sector until 2050, as well as its relationship with the conservation of fish fauna, especially long-distance migratory species. The hydroelectric projects in operation and planned were analyzed using data obtained from the National Electric Energy Agency. A literature review was carried out to assess the fish species of the Tocantins–Araguaia ecoregion, with an emphasis on long-distance migrants. In general, 75 hydroelectric dams are in operation, and a further 119 projects are in the electricity sector’s plans for construction by 2050 in the Tocantins–Araguaia ecoregion, including a stretch of the basin above the Tucurui dam, which will accentuate the fragmentation in the area. Of the 702 species found in the region, 31.1% are endemic, 6.1% are endangered, and several long-distance migratory species have had their populations restricted. Analysis of this information highlights the widespread impact on the ichthyofauna, affecting both species with a restricted distribution and migratory species with a long-distance distribution. The studies associated with the projects contribute to the advancement of knowledge, but they are only carried out after the works have been defined, which makes it difficult to plan conservation in advance. Transformations in the basin are imminent given the current changes and those expected in the coming years because of the electricity sector’s planning for the region. Considering the inseparable relationship between biodiversity and socio-environmental and cultural diversity, fish conservation is intrinsically linked to the conservation of socio-diversity and the effective participation of local communities from the start of the process. Fish depend on water, and people need both water and aquatic diversity. In conclusion, a well-structured and adaptative conservation plan, combined with the integration of effective fish routes, can contribute to the sustainable development of hydroelectric projects while safeguarding the biodiversity and ecological integrity of the Tocantins–Araguaia Basin.

The ecological ‘attraction’ and ‘production’ functions of reef areas have been the subject of ongoing debate requiring further clarification. The present study focused on the black rockfish (Sebastes schlegelii), an economically dominant species in reef areas of Dabuquan Bay. Comparisons of stable carbon (C) isotopes between the muscle and liver tissues of black rockfish were conducted to identify residency and potential sources of non-resident individuals in the coastal Yellow Sea, China. Subsequently, isoscape values, derived from C isotopes of zooplankton gathered from inshore and offshore areas surrounding the reef, were compared to determine potential sources of the non-resident black rockfish individuals. According to the results, (1) the isotopic values between the muscle and liver tissues of black rockfish remained consistently aligned across both reef and control areas but showcased significant seasonal variations, and (2) the residency ratios of individuals within the reef area exceeded 84% across all seasons, highlighting the prolonged stays of this species. The findings are consistent with previous studies on rockfish residency and could facilitate the formulation of strategies for local stock enhancement and management. Full article

The southern coast of Central Java Province is one of Indonesia’s largest eels (Anguilla spp.) fishing grounds. The annual eel catches in this region showed an increasing trend in 2011–2014 but then plummeted in 2019–2021. However, studies on stock status are lacking to provide an effective management plan to prevent the collapse of eel fisheries. Therefore, this study assessed the state of freshwater eels in Southern Central Java using a data-limited method, catch-based maximum sustainable yield (CMSY). The analysis revealed a swift stock depletion, shifting from a healthy state in 2011 to a concerning red zone in 2015–2018. Subsequently, the stock began a recovery phase in 2019, but the recent trajectory raised concerns as it approached the red zone again, signaling the urgency of implementing a rebuilding plan. The simulation of several rebuilding scenarios suggests that reducing fishing mortality to 80% of the FMSY (maximum sustainable fishing mortality) can balance production and conservation objectives, achieving the quickest stock rebuilding with minimal catch loss. This study showed that eel stock could be rebuilt by reducing fishing pressure to preserve a surplus of individuals who can complete their migration and spawning cycles. Full article
