Project description:In this study, we attempt to characterize the transcriptomic profile of the Asian seabass brains collected from the male and female sexes. The objective is to identify genes that show sexually dimorphic expression in the brain of this species. For this experiment, Asian seabass were collected from the Marine Aquaculture Center of the Agri-Food & Veterinary Authority of Singapore. There were no treatments carried out in this experiment. Four brains from adult male seabass (5 years old) with M3-type testis and four brains from adult female seabass (5 years old) with F3-type ovaries were used in this experiment. (Gonads were examined by histology and classified according to sexual maturation status as described by Guiguen and colleagues (Guiguen et al. Environmental Biology of Fishes, 1994)).

Project description:In this study, we attempt to characterize the transcriptomic profile of the Asian seabass gonads at various developmental stages. The protandric Asian seabass or barramundi (Lates calcarifer) typically matures as a male at approximately 2–4 years of age and then changes sex to a female in later years. For this experiment, Asian seabass of several ages were collected from the Marine Aquaculture Center of the Agri-Food & Veterinary Authority of Singapore and from farms around Singapore. There were no treatments carried out in this experiment. The gonads were examined by histology and classified according to sexual maturation status as described by Guiguen and colleagues (Guiguen et al. Environmental Biology of Fishes, 1994). Altogether, we analyzed 22 gonadal samples that could be classified into six different types of gonads.

Project description:In this study we present the prokaryotic community dynamics in a hatchery recirculating aquaculture system (RAS) of sole (Solea senegalensis).
Project description:In this study, the relative effect of consuming five different commercial feeds (Feed B-F) and and frozen fish (control; Feed A) for two months on our selected juvenile Asian seabass (77.3g ± 22.4g) were investigated. The growth performance, the biochemical analysis of their flesh, the histology of their midgut and the transcriptome of their midgut and liver were compared to each other and controls. Our customised agilent microarray platform (GPL17855), were used to investigate the liver transcriptomic expression of the different Groups fed with different Feeds. No differential expression were detected between commerical Feeds (B, C, E and F). A total of 397 differentially expressed transcripts (Foldchange cutoff: -1.5≤ or ≥1.5, Pvalue with FDR (<0.05) were detected between Feed D and control Feed A.
