Abstract Microplastic (MP) contamination in fish may occur via their feeding behavior and ingestion of contaminated prey. This study investigated the presence MPs predator Lutjanus russellii (Russell’s snapper) its prey along Chumphon coast Central Gulf Thailand. Stomach contents L . were analyzed to identify species. Prey species then sampled from same geographical area as specimens for subsequent MP analysis. The dietary habits classify it a generalist carnivore, consuming diverse range...
The transparent zebrafish enables researchers to study the morphology and distribution of cells tissues in vivo. To capture dynamic processes germ cell proliferation juvenile ovarian development vivo, we established transgenic (TG) lines allow us monitor changes ovaries living fish. original line with fluorescence was occasionally established. Although cDNA integrated strain constructed for expression enhanced green fluorescent protein (EGFP) driven by medaka β-actin promoter, EGFP is...
Two essential processes, oocyte maturation and ovulation, are independently induced, but proceed cooperatively as the final step in oogenesis before oocytes become fertilizable. Although these two processes induced by same maturation-inducing steroid, 17α, 20β-dihydroxy-4-pregnen-3-one (17, 20β-DHP), zebrafish, it has been suggested that receptor, thus signal transduction pathway is different for each process. much progress made understanding molecular mechanisms underlying induction of...
Using an in vivo assay, we selected 11 genes that were highly upregulated during the induction of ovulation zebrafish using microarray analysis and RNA sequencing. The starmaker gene (stm) was one these genes. Although stm has been previously reported to be involved otolith formation early development zebrafish, detected its expression eggs showed related fertilization by establishing knockout strain CRISPR/Cas9 system. Further phenotypic fish conducted this study. With a higher...
We previously reported the microarray-based selection of three ovulation-related genes in zebrafish. used a different method this study, RNA sequencing analysis. An additional eight up-regulated candidates were found as specifically ovulation-induced samples. Changes gene expression confirmed by qPCR Furthermore, up-regulation prior to ovulation during natural spawning was verified samples from pairing. Gene knock-out zebrafish strains one candidates, starmaker (stm), established CRISPR...
The false mussel Mytilopsis sallei (Récluz, 1849) is a bivalve indigenous to the tropical western Atlantic that has become invasive in Southeast-Asia. Establishment of M. populations Thailand was reported 2008 and it spread several locations along both Gulf Andaman Sea coasts. survival planktonic larvae oceanic salinity known be poor so these may result multiple introductions, propagule exchanges between limited. To test this, we investigated variability cytochrome oxidase subunit I within...
Two species of Pilargidae, Sigambra pakbaraensis sp. nov. and S. sirilukae are described from different coasts Southern Thailand (Andaman Sea the Gulf Thailand). Both belong to subgroup which lack ventral cirri at chaetiger 2 have capillary notochaetae. is Andaman coast can be distinguished other in genus by occurrence first dorsal hook 8, presence capillaries notopodia, 14 pharyngeal papillae. it clearly all having 12 pharynx papillae, an elongate median antenna with a large ceratophore,...
Ponyfish (Perciformes: Leiognathidae) are a diverse group of mainly small, planktivorous fishes that comprise much the teleost component found in by-catch trawlers Thai waters. The generic taxonomy ponyfish has been revised many times, which resulted confusion historical records fishing data. Moreover, since two monsoon seasons affect different coasts Thailand at times year, their effects likely to have separate impacts on marine fish diversity according time year. By-catch samples totaling...
Abstract Shark fins are among the most highly prized seafood products in world with massive consumption Asia over past several decades. The demand for shark is a major driver of enormous population declines elasmobranchs that generally vulnerable to overexploitation. This study aims better understand species composition fin Thailand and their conservation statuses by using DNA-based identification. Various types sizes were collected from 4 locations Thailand. DNA barcoding method based on...
