Summary: The study in Singapore found that barramundi farmed in sea cages are undergoing precocious sex change, with a decrease in male individuals and an increase in females as early as 2-3 years old. This phenomenon challenges hatcheries in selecting and maintaining male fish for breeding purposes, and further investigation is needed to understand the causes of this early sex change.

Summary: Barramundi, an economically important species in the Asia-Pacific region, has been threatened by various infectious diseases including the newly emerging Lates calcarifer herpes virus (LCHV). This study investigated the histology of LCHV outbreaks and identified a pathognomonic feature, the presence of intra-nuclear inclusion bodies (IIBs), in infected fish. Experimental infection confirmed the presence of IIBs in multiple organs, providing a valuable tool for the histological diagnosis and surveillance of this viral disease in barramundi farming countries.

Summary: Fish meal is a limiting factor for fish feed development. The use of forage fish as a protein source in fish feed is unsustainable and hinders the aquaculture industry. Researchers have explored alternative protein sources, such as food industry by-products and local raw materials. This study found that most echinoderm species are unpalatable for barramundi fish and should not be recommended as an ingredient in barramundi feed.

Summary: Selective breeding is crucial for sustainable aquaculture, and barramundi is no exception. Developing a germ cell transplantation method is essential for preserving diverse genetic characteristics. Transplanting frozen germ cells into recipients is a powerful tool for obtaining the next generation.

Summary: The physicochemical quality and shelf-life of barramundi fillets fed with a mixture of poultry by-product meal (PBM), full-fat Hermetia illucens (FHI), and defatted HI (DHI) were compared to those fed with a fishmeal (FM) control diet. The study found that the compositions of fillets were not influenced by the test diets, but the PBM-HI mixture improved sensory quality. Moreover, the PBM-HI-based diets enhanced the texture profile and maintained the quality of barramundi fillets during storage.

Summary: Efficient aquaculture management requires optimizing feed intake to balance fish productivity and environmental waste. Automated feeders with daily feed intake (DFI) prediction capabilities are popular for achieving this balance. This study optimized DFI prediction using various learning algorithms and nonlinear functional forms, showing that feed selection, fish characteristics, and environmental factors significantly impact DFI. Nonlinear models demonstrated higher accuracy, and the use of adaptive algorithms facilitated the development of effective DFI prediction models.

Summary: This study examined the taste attractiveness of 21 amino acids and 4 taste substances for barramundi, and investigated their feeding behavior. The results showed that citric acid, cysteine, and alanine were palatable, while sucrose and 7 amino acids had an aversive taste. Barramundi often made repeated grasps and rejections of pellets, leading to the destruction of the pellets.

Summary: The study evaluated the utilization of multi-trait genomic selection in improving breeding value prediction accuracy for growth performance and fillet yield in Asian seabass farming. Compared to traditional methods, genomic BLUP significantly increased the prediction accuracies for these traits. Additionally, multi-trait prediction under GBLUP showed slightly better performance than single-trait analysis.

Summary: The relationship between individual growth rate and the timing of sex change plays a significant role in reproductive output and population productivity. Fast growth is associated with a younger age at sex change, but not necessarily a smaller size at sex change. Individuals that grow faster, particularly as large females, contribute more to population fecundity and ultimately obtain higher fitness.

Summary: The study found that Emamectin benzoate (EB) was effective in reducing sea lice infections in hybrid groupers in saltwater net-pen sites in Hong Kong, with a noticeable reduction observed from the last day of treatment to 14 days after the final EB treatment. However, there was a significant variation in EB concentrations in fish on the last day of treatment, indicating uneven distribution of medication in daily rations may have impacted the treatment response. Preliminary evidence suggests that EB could be a potential treatment for sea lice in Hong Kong and other regions of Southeast Asia.

Summary: Marine farming of barramundi in Southeast Asia is currently affected by viral diseases, with scale drop disease virus and L. calcarifer herpes virus being detected in all sampled fish. Histopathology showed abnormal fat accumulation in the livers of sick fish, inflammation and necrosis in the kidneys, and severe necrosis in the spleen. RNA degradation in the kidney and spleen of sick fish indicated organ failure in advanced stages of scale drop disease.

Summary: Scale drop disease virus (SDDV) is an emerging virus in Asian countries that infects barramundi, resulting in huge economic losses in aquaculture industries. The traditional methods of diagnosing viral diseases in aquaculture are inefficient, while the environmental DNA (eDNA) approach offers an innovative way to detect specific pathogens before animals become infected. This study tested the feasibility of using eDNA to detect SDDV and found that ddPCR is a more efficient technique for low-level detection of SDDV in aquatic environments.

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.
