Alternations in oxidative stress, apoptosis, and innate-immune gene expression at mRNA levels in subadult tiger puffer (Takifugu rubripes) under two different rearing systems

Effects of different biofloc sizes on the short‐term stress of Japanese seabass, Lateolabrax japonicus (Cuvier), juveniles reared in biofloc aquaculture systems

“…Antioxidant enzymes, such as SOD, CAT and glutathione (GSH), play a key role in protecting fish against the toxic effects of reactive oxygen species (Gao et al, 2021). SOD is the first defence mechanism against oxidative stress, as it converts oxygen free radicals in cells into hydrogen peroxide (Jia et al, 2019). Subsequently, CAT and GSH remove hydrogen peroxide and reduce its toxic effects (Jia et al, 2019).…”

“…SOD is the first defence mechanism against oxidative stress, as it converts oxygen free radicals in cells into hydrogen peroxide (Jia et al, 2019). Subsequently, CAT and GSH remove hydrogen peroxide and reduce its toxic effects (Jia et al, 2019). The results of this study showed that the SOD and CAT activities in the SG group gradually increased with time; however, the SOD and CAT activity levels in the LG remained stable after an initial decrease to a low level.…”

Effects of thermal stress and hypoxia on skin mucus immune and stress responses in blue gourami ( Trichogaster trichopterus ) cultured in intensive recirculation aquaculture system and semi‐intensive systems

“…There are a wide range of studies on RAS technology, an intensive aquaculture system with water recirculation (Jia et al, 2016(Jia et al, ,2019Liu et al, 2018;Mota et al, 2019;Yogev et al, 2020), but there is inadequate information on welfare and stress resistance of ornamental fish reared in this intensive system (Vanderzwalmen et al, 2020). The present study evaluated the skin mucus immune and stress responses to thermal hypoxia stresses in a valuable ornamental fish, blue gourami (T. trichopterus) reared in both RAS and TPS systems.…”

Comparative Transcriptome Analysis of Female and Male Fine-Patterned Puffer: Identification of Candidate Genes Associated with Growth and Sex Differentiation

“…Obviously, it is widely accepted that genes encoding components of the somatotropic axis play critical roles in regulating the formation of skeletal muscles in finfish, including the growth hormone gene (Gh), insulin-like growth factors (Igf ), somatostatin and their carrier proteins and receptors [50]. Jia et al [51,52] showed that specific growth rate, body weight and plasma growth hormone of female tiger puffers (Takifugu rubripes) reared in an offshore sea cage aquaculture system (OSCS) were significantly higher than those of fish reared in other aquaculture systems. The mRNA expression results indicated that female individuals reared in the OSCS showed higher somatic growth axis-related genes (Igf1, Igf2, Igf1r, Igf2r, Ghr1, and Ghr2) expression levels.…”
