The Portuguese oyster ( Crassostrea angulata ) is a commercially significant aquaculture species, gaining rapid popularity, particularly in Asia. Growth-related traits, along with shell and mantle colouration, are key determinants of market value in farmed oysters. To support trait improvement in breeding programs, this study investigates the genetic architecture of economically important traits, including shell length, shell...

Prior to this study, Myanmar was known to host 15 species of snakehead fishes (genus Channa) distributed across Southeast Asia. The region, characterized by its confluence of diverse river systems and two biodiversity hotspots, is presumed to have notable gaps in its biodiversity assessments. Recently, a new snakehead species, Channa shingon, was discovered in China, with its potential distribution in Myanmar warranting furthe...

The collective understanding of global-scale evolutionary trends in barracuda mitogenomes is presently limited. This ongoing research delves into the maternal evolutionary path of Sphyraena species, with a specific focus on the complete mitogenome of Sphyraena sphyraena, sourced from the Atlantic Ocean through advanced next-generation sequencing. This mitogenome spans 16,841 base pairs and encompasses 37 genes, including 13 pr...

The complete mitochondrial genome of endangered Enteromius thysi was determined from Cameroon in Western Africa. The genome was 16,688 bp in length, comprising 37 genes (13 PCGs, 2 rRNAs, 22 tRNAs, and an AT-rich control region). The heavy strand accommodates 28 genes (12 PCGs, 2 rRNAs, and 14 tRNAs), whereas the light strand holds 9 genes (NAD6 and 8 tRNAs). The E. thysi mitogenome is AT-biased (60.5%), as exhibited in other...

The diet of the Antarctic toothfish ( Dissostichus mawsoni ) was analyzed using metabarcoding to determine whether spatiotemporal factors are related to its feeding ecology. A diet metabarcoding analysis was conducted for five years from 2016 to 2020 using 1,777 samples collected from two distantly located subareas, 88.3 and 58.4.1. Metabarcoding results revealed 105 prey haplotypes (29 families, 45 genera) in the stomach cont...

The feeding and spawning grounds for seahorses have been lost due to nationwide coastal developments in South Korea. However, little information on the feeding ecology of the Korean seahorse (Hippocampus haema) is currently available. The main objective in this study was to understand the feeding strategy of H. haema on the basis of DNA analysis of the contents of the guts. This is the first study on the feeding ecology of H....
