Summary: The study found that black sea bream eggs had the highest density in areas with major oyster farms in Hiroshima Bay. However, eggs had a low density in areas with low salinity, suggesting that black sea bream avoid spawning in those areas. The study also suggests that while oyster farms may provide more food sources for efficient spawning, they may also have negative impacts such as hosting jellyfish that prey on eggs and limiting water flow that can affect the survival of fish eggs.

Summary: This study aimed to evaluate the catabolism and retention of lipids in Seriola dorsalis juveniles under optimum levels of restriction. The lipid metabolism genes involved were determined. The results showed that saturated fatty acids were mainly oxidized, followed by monounsaturated fatty acids and linoleic acid, while long-chain polyunsaturated fatty acids were only oxidized in excess. The gene expression analysis revealed differences in the activation and uptake of fatty acids. The study suggests that 13% crude fat is the ideal amount for S. dorsalis.

Summary: The study investigated the hatching success of eggs produced by Acartia tonsa adults cultured at different salinities and temperatures. Results showed that the hatching of stored eggs was strongly influenced by the temperature and salinity of the culture environment, while fresh eggs were less affected by these variables.

Summary: This study investigated the biological bases of embryonic development in South Pacific bonito Sarda chiliensis chiliensis eggs, identifying 31 embryonic stages until hatching. Differentiating into five periods, with significant morphometric variability, the translucent telolecitic eggs hatched on the third day of incubation, contributing new insights into the embryonic development of this species.

Summary: There is a growing consensus that fish are sentient beings capable of experiencing pain and suffering, leading to the challenge of assessing the welfare of farmed fish. This study explores the use of Qualitative Behavioral Assessment (QBA) as a potential tool for monitoring the welfare of farmed salmon. The results show promise in using QBA to efficiently assess the welfare of juvenile salmon under farmed conditions.

Summary: Exposure to curry tree leaf extract disrupts cuticular development, immune response, and oxidative stress pathways in Anopheles gambiae s.s larvae. These pathways could be targeted for the development of more effective curry tree phytochemical-based IGRs against An. gambiae s.s mosquito larvae.

Summary: The future of European eel aquaculture relies on closing the life cycle in captivity and developing larval rearing technology. This study reveals that early and gradual salinity reduction benefits larval eel growth and survival, but may cause heart edema. Consideration of genetic programming and environmental interactions is essential for the future of eel aquaculture.

Summary: In this study, the effects of two anticoagulants (heparin sodium and K(2)EDTA), storage time, and temperature on the hematological values of Arapaima gigas juveniles were evaluated. The results showed significant differences in hematocrit, lymphocytes, and neutrophils when comparing anticoagulants at 0 hours of storage. K(2)EDTA at 28 degrees Celsius maintained stable blood indices MCV, MCHC, and MCH for up to 5 hours.

Summary: Fishmeal, a conventional and unsustainable protein source, is becoming scarce and expensive. Black soldier fly (BSF), as an alternative protein source, has been tested in aquafeed formulation with promising results. However, the effects of BSF supplementation varied among fish species, with omnivores benefiting and carnivores and herbivores experiencing negative impacts. It is important to consider the species-specific effects when using BSF as a substitute for fishmeal.

Summary: This study documents an outbreak of lymphocystis disease virus (LCDV) infection in cultured juvenile John's snapper in Malaysia. The outbreak resulted in lethargy, lymphocysts, and mortality in the affected fish. PCR and sequence analyses confirmed LCDV as the cause of the outbreak. This study highlights the importance of monitoring and managing LCDV infection in cultured fish to prevent economic losses.

Summary: Aquaculture is a rapidly growing industry, but it faces challenges from bacterial pathogens that infect fish. Fish reared in high-density aquaculture facilities are highly susceptible to disease outbreaks, leading to significant economic loss. Vaccination is considered a reliable method to prevent infections and plays a key role in the sustainable management of aquaculture production worldwide.

Summary: The study evaluated the efficacy of orally delivered V. anguillarum bacterin on lumpfish and found that oral immunization was ineffective, while intraperitoneal delivery provided protection against vibriosis. This indicates that orally administered bacterin did not reach deep lymphoid tissues, rendering oral immunization ineffective.

Summary: The study investigated the effects of black soldier fly (BSF) meals on the growth performance of zebrafish and found that defatted BSF meals could replace fishmeal without negative impacts. The results showed potential for BSF prepupae meal to be a beneficial alternative protein source for aquaculture.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
