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: 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: 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: A study found that there are cellular, ultrastructural, and cellular differences between color variants of barramundi. The number and distribution of melanophores, which produce melanin, vary among the golden, silver, and black phenotypes. The findings have commercial significance for increasing the production of rare color variants.

Summary: Lates calcarifer, also known as Barramundi or Asian seabass, is a highly productive fish species suitable for large-scale aquaculture. However, the dense populations in aquaculture settings increase the risk of infectious diseases, which negatively impact yield. Immunization of juveniles and development of new immunization agents are crucial for improving aquaculture efficiency and food security.

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: This study assessed the use of microwave-assisted induction heating (MAIH) in processing barramundi meat. The results showed that prolonged heating reduced microbial contamination and changed the physicochemical qualities of the meat. The recommended optimal heating conditions were 90 degrees C for 110 s and 70 degrees C for 130 s.

Summary: Reliable short-term chilled sperm storage is crucial for captive breeding of barramundi. This study optimized the composition of a non-activating medium (NAM) for short-term chilled storage by mimicking the biochemical profile of captive-bred barramundi's seminal and blood plasma. The optimized NAM significantly extended the functional lifespan of spermatozoa during chilled storage.

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 rate of global wildlife extinctions is increasing, and conservation breeding programs are needed to preserve many species. However, preserving the genetic diversity of founder populations may also preserve characteristics that make them vulnerable to extinction. Targeted genetic intervention (TGI) is introduced as an alternative approach to promote traits that enable species to persist in the face of threats by changing the incidence of alleles that impact fitness.

Summary: The study found that there was no general pattern of increasing female-specific DNA methylation markers with increasing length in barramundi, and female-specific DNA methylation arises rapidly during sex change. Additionally, differences in DNA methylation between males and females of similar lengths suggest that female-specific DNA methylation occurs rapidly during sex change rather than gradually with fish growth. Moreover, region-specific differences in length-at-sex change are accompanied by differences in DNA methylation, which are consistent with variability in sea temperature and salinity.

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.
