Summary: To screen potential antigen proteins for snakehead vesiculovirus (SHVV), glycoprotein (G), matrix protein (M), nucleoprotein (N), and phosphoprotein (P) of SHVV were cloned, analyzed, and expressed. Four recombinant proteins were used as subunit vaccines to immunize snakehead. Results showed that the glycoprotein (G) had the best immune effect, with the highest relative percent survival (RPS) of 83.3%, followed by the matrix protein (M, RPS: 66.7%), nucleoprotein (N, RPS: 50.0%), and phosphoprotein (P, RPS: 8.3%). Glycoprotein (G) was identified as a better candidate protective antigen of SHVV.

Summary: The study found that snakehead are capable of digesting starch efficiently, but diets with high carbohydrate content reduce the efficiency of digestible energy for energy retention. Snakehead prioritize digestible protein intake for protein gain. The estimated energy efficiencies of digestible protein, fat, and carbohydrates for energy retention were 53%, 79%, and 5% respectively.

Summary: This study provides an annotated list of the 13 known species of Carangoides in Malaysian waters and analyzes their genetic characteristics. The study found that due to the mixed morphological and meristic characteristics of species in the genus Carangoides, they are often reported as a collective group rather than individual species. This hinders the accurate reflection of the number of species harvested in fisheries landing statistics and hampers the efficient sustainable exploitation of a particular species. In addition, the study identifies two species with significant intraspecific divergence, indicating the need for a more detailed analysis of the taxonomic status of certain individuals within these species.

Summary: This study investigated the genetic variability, structure, and phylogenetic relationships of the brushtooth lizardfish from the east coast of Peninsular Malaysia. The results showed moderate haplotype diversity and low nucleotide diversity in this population, suggesting a recent population expansion. The study also found higher nucleotide polymorphism in near shore and shallower waters, indicating better habitat quality and/or less fishing pressure. Genetic homogeneity within the study area and genetic similarity to populations in the Mediterranean coast of Turkey were observed. These findings highlight the importance of protecting habitat areas and implementing a single-stock management regime for the conservation of this economically important fishery resource.

Summary: We analyzed the phylogeny and biogeography of the Ambassidae family, a fish group that is found in freshwater, brackish, and marine coastal habitats across the Indo-West Pacific region. Our results show that the two largest genera within Ambassidae, Ambassis and Parambassis, are not monophyletic. The common ancestor of Ambassidae was a freshwater species that lived in Australia about 56 million years ago. We propose that two long-distance marine dispersal events from Australia explain the distribution of ambassids, with one towards Southeast Asia in the early Cenozoic and another towards Africa in the mid-Cenozoic. The phylogenetic signal associated with the salinity adaptation of these events was not detected, possibly due to the selective extinction of intermediate marine lineages.
