Special Issue Information

Dear Colleagues,

There is compelling evidence that wild harvests of fish, crustaceans and other aquatic species will not be able to keep up with the demands of a global population that is expected to reach 9.7 billion by 2050 [1]. Around 90% of the world’s stocks are now fully fished or overfished, while habitat degradation and human-induced climate change are placing increased stress on all aquatic life. Higher incomes and greater consumer awareness of the nutritional benefits of aquatic products are pushing global per capita consumption to record highs [2].

It is widely acknowledged that sustainable aquaculture development is critical for meeting global food needs. Important advances in the development of more environmentally sound and sustainable production systems are being made on multiple fronts [3]. Sustainable aquaculture, however, must be viewed through a broad lens that encompasses the social dynamics and diversity of the communities in which it takes place. This Special Issue aims to investigate the contribution of aquaculture to community development, and the challenges associated with local resource use, from a variety of perspectives. These include, but are not limited to, food security, poverty alleviation, governance, and livelihoods. Insights from marine and freshwater environments, and developed and developing nations are welcome in this issue.

The supply of animal feed is one of the main concerns of producers in the aquaculture industry, including aspects such as the cost of fish flour and its nutritional balance. The aim of this study was the preparation of a pellet-type fish food using powdered Spirulina sp. cultivated as a protein source supplemented with agro-industrial waste, and its evaluation to comply with the necessary parameters for the elaboration of extruded pellets. Spirulina sp. was cultivated in a photobioreactor at a volume of 50 L, separated by decantation and dried. The proximal characterization was 6.79% ± 0.05 moisture, 6.93% ± 0.01 ash, 66.88% ± 0.33 protein, and 5.50% ± 0.26 fat. Subsequently, flours were prepared using cassava leaves, gliricidia leaves, and rice husks. The results for the cohesion showed that the flours obtained to comply with the necessary parameters for the elaboration of extruded food. The fish feed was prepared in pellet form using the formulation for fattening Tilapia: Spirulina sp. (20%), cassava leaf flour (50%), gliricidia leaf flour (20%) and flour of rice husk (10%). Floatation analysis showed that 60% of the pellets floated for more than 40 min, and 80% retained their shape for 4 h. The results show that the obtained product can be used as fish feed, due to the lowest disintegration, together with its great capacity for water absorption and especially, its greater flotage due to the expansion effect, are physic characteristic determinants so that the fish has more time to consume extruded diets and avoid losses.

Protected areas have been used worldwide to conserve natural resources. Nevertheless, economic activities to provide income for communities living within and surrounded by conservation areas remain an issue. This study aimed to assess the sustainability of a Deuterodon iguape hatchery, situated within an Atlantic Rainforest Park, to leverage grow-out farming of this small native fish, affording income and food security for local families. We have used a set of indicators of economic, social, and environmental sustainability. The initial investment is about US$ 40,000, which should see a return in ~2 years. The internal rate of return is close to 50%, including the externality costs, which is attractive for both public and private investors. The hatchery generated few direct jobs, but the workforce can be recruited from the community, and the hatchery can enable the establishment of several small grow-out farms, leveraging the development of indirect jobs and self-employment. The system had a low environmental impact, showing a minor release of pollutants, a low risk for biodiversity, and absorption of 18 g of CO2 equivalent per thousand post-larvae produced, contributing to the struggle against climate change. Therefore, the D. iguape hatchery demonstrates the potential of combining biodiversity conservation and income generation, meeting the Sustainable Development Goals of Agenda 2030. Full article
