Natural selection endows animals with the abilities to store lipid when food is abundant and to synthesize lipid when it is limited. However, the relevant adaptive strategy of lipid metabolism has not been clearly elucidated in fish. This study examined the systemic metabolic strategies of Nile tilapia to maintain lipid homeostasis when fed with low- or(More)
Peroxisome proliferation activated receptor α (PPARα) is an important transcriptional regulator of lipid metabolism and is activated by high-fat diet (HFD) and fibrates in mammals. However, whether nutritional background affects PPARα activation and the hypolipidemic effects of PPARα ligands have not been investigated in fish. In the present two-phase study(More)
In this study, we explored the function of arachidonic acid (ARA) in adipogenesis in the grass carp (Ctenopharyngodon idellus) using in vivo and in vitro models. An 8-week feeding trial was performed using three isonitrogenous and isoenergetic purified diets: ARA-free, ARA, and ARA + acetylsalicylic acid [ASA, a cyclooxygenase (COX) inhibitor]. Fish were(More)
The practical level of fish meal replacement by plant proteins in aquaculture feed varies greatly among species. This study investigated partial or complete replacement of fish meal (FM) by cottonseed and soybean meal (CS) in Chinese mitten crab Eriocheir sinensis. Cottonseed and soybean meals were equally mixed to form five isonitrogenous and isocaloric(More)
