“…In this context, between 30 to 40% of fish feed is released as a waste load to water bodies 4,8,11 . This is a particular problem, as the cost of fish feed is a significant challenge for aquaculture operations [12][13][14][15][16][17][18] .…”

Background: Giant gourami (Osphronemus goramy Lacepede, 1801) has become popular aquaculture in Indonesia. However, information on the feed used is minimal. This study analyzed the change in feeding nutrition, fish growth, feed efficiency, and body-carcass using product formulated from water coconut, palm sap sugar, and fungus. Methods: A total of 2,000 ml coconut water and 1,000 ml of palm sap sugar solution were formulated. Each product formulated was added with 6 g of Aspergillus niger (called product P1), 6 g of Rhizopus oligosporus (called product P2), and 6 g of Saccharomyces cerevisiae (called product P3). Commercial feeds supplemented with P1, P2, and P3 products are designated P1, P2, and P3 diets. Commercial feed added to freshwater is called the P4 diet (placebo). Their dosage is 300 ml/kg of feed. Gurami sago juveniles (initial weight 50±2.5 g and length 13.2±0.4 cm) were stocked in triplicate nets (2×1×1 m) in a freshwater concrete pond with a stocking density of 30 fish/net, an initial feeding rate of 3% per day until study termination. Results: Our results support our hypothesis that different product formulations have a significant effect (p<0.05) on growth performance and feed efficiency. At the same time, supplementing commercial feed with varying formula products has a significant impact (p<0.05) on the fatty acid composition of the diets and carcass body of gurami sago. Conclusion: Diet P2 contains a higher concentration of fatty acids to increase body weight, feed efficiency, and the best carcass fatty acid composition than other experiments for sago gurami reared in freshwater concrete ponds.

“…Therefore, climate change may not only decline the production in the fisheries and aquaculture sector but also decline the expected production. In all the aspects analyzed, the province of Zambezia appeared to have had the greatest impact from cyclone due not only to the greater number of districts with aquaculture production initiatives but also with a greater number of production areas, that mainly small-scale for the livelihood of communities (Villasante et al, 2015;IDEPA Institute of Fisheries and Aquaculture Development, 2020;Muhala et al, 2021). Extreme climatic events such as cyclones, drought, and floods have increased dramatically in recent decades in Mozambique (EM-DAT, CRED/UCLouvain, 2020).…”

“…On the other hand, Rutkayova et al (2017) and Maulu et al (2020), claim that extreme events such as cyclones, floods, and storms, will negatively affect aquaculture production through loss of fish during the invasion of floodwaters in ponds, in addition to the introduction of new species that can create aquaculture unsustainability problems due to the entry of exotic species (Edwards, 2015). In addition, most production tanks in Mozambique are shallow and smaller in size, ranging from 150 to 300 m 2 on average (Companhia and Thorarensen, 2012;Muhala et al, 2021). This factor increases the vulnerability of the ponds to flooding mainly in the lower regions and the invasion of Silva and Soto, 2009].…”

“…Most cage aquaculture production in tropical regions of Africa is carried out in lakes, reservoirs, and riverbeds (De Silva and Soto, 2009;Hasimuna et al, 2019;MIMAIP, 2019;Muhala et al, 2021). Cage production in Mozambique is an unremarkable activity.…”

“…Climate change and its effects pose challenges to everyone, especially developing countries where predictions of the occurrence of extreme events as a result of climate change have been made, and also the conditions for building resilient infrastructure are weak. Aquaculture production in Mozambique is mostly practiced by small producers and with low investment, needing a lot of help from the government and private sectors to implement it (Muhala et al, 2021). The same small investment scenario can be seen in the artisanal fisheries sector.…”

Fisheries and Aquaculture are among the most popular activities in coastal regions of the world. In addition, both correspond to high-risk activities within a climate change context as they are vulnerable to environmental changes that threaten the socio-economic sustainability of the fishing communities that depend on fish for food security and income generation. In 2019, the central part of Mozambique was hit by two unprecedented cyclones: Idai and Kenneth that killed over 600 people and left nearly 2.2 million people in need of urgent assistance. The aim of the present study was to investigate the impacts these cyclones had on fisheries and aquaculture in the provinces of Sofala and Zambézia in Mozambique. The study further seeks to propose strategies that could be adopted by the communities to minimize the risks in the future. For the construction of the database, both secondary and primary data collection approaches were used to characterize the cyclone events. Secondary data was collected through sector reports and previously published articles, while primary data was collected through interviews with fishers, sector employees, and aquaculture producers in the affected provinces. The results revealed that these natural events had both a direct and indirect impact on fishing, as they affected more than 1,440 fishermen that lost 590 vessels, 1,800 fishing gear, and 67 boat engines in Sofala province. In Zambézia province, aquaculture producers lost 169 fish ponds, two cages, and 606,000 lost fry, while in Sofala province, 58 fish tanks, 204 cages, and 257,500 fish fry were lost. Overall, our study reveals the vulnerability of fisheries and aquaculture to extreme events particularly the cyclones in Mozambique. Lack of knowledge regarding climate change, advanced preventive measures, and poor adaptive capacity makes the sectors more vulnerable to disasters. Therefore, it is recommended to improve awareness programs, introduce measures and policies that promote resilience and optimum adaptive efficiency.
