“…This is the reason for suppression of fish growth performance by oxidized fish oil. Also, oxidized fish oil could cause oxidative damage in animals (Yuan et al, 2014;Chen et al, 2012b;Lu et al, 2017;Yang et al, 2014). In the present study, profound alterations in liver histology of grass carp were noticed after feeding oxidized fish oil.…”

Abstract3-Hydroxy-3-methylglutaryl-Coenzyme A reductase (HMGR) is a rate-limiting enzyme for cholesterol biosynthesis. The aim of this study was to identify HMGR molecular characterization in grass carp (Ctenopharyngodon idellus), and to evaluate regulation of its expression by oxidized fish oil. Specific primers were designed for 3'RACE and 5'RACE to gain HMGR cDNA sequence of grass carp and to clone full-length HMGR cDNA. This cDNA covered 3591 bp, with 2526 bp for the open reading frame (ORF), 77 bp for 5'-untranslated region (UTR) and 988 bp for 3'UTR. ORF encoded a protein consisting of 841 amino acids. The result revealed that HMGR mRNA is predominantly expressed in liver. Multiple alignments and phylogenetic analysis indicated that grass carp HMGR has a high degree of conservation with other fish species. A 10-week feeding trial was conducted to investigate effects of offering diets containing fresh and oxidized fish oil on HMGR expression in liver and intestine of grass carp. The results showed that HMGR expression in fish fed the diet containing oxidized fish oil was significantly higher than fish fed the fresh fish oil after 10, 20, 30 and 70 days of feeding. Serum diamineoxidase (DAO) activity of fish was also increased by oxidized fish oil.

“…Species‐specific differences exist in the growth responses to dietary OFO. When fed on diets containing OFO, a reduced body weight gain and FE were reported in Arctic charr ( Salvelinus alpinus ), large yellow croaker ( Larmichthys crocea ), red sea bream ( Pagrus major ), and whiteleg shrimp ( Litopenaeus vannamei ) (Gao et al, ; Kubiriza et al, ; Wang et al, ; Yang et al, ). Contrary to these reports, enhanced feed intake and body weight gain were observed in Nile tilapia ( Oreochromis niloticus ) and largemouth bass ( Micropterus salmoides ) (Chen et al, ; Kubiriza et al, ).…”

“…Dietary lipid is essential to farmed fish and crustaceans (Chen et al, ; Hung, Cho, & Slinger, ; Saoud, Yta, & Ghanawi, ; Suprayudi, Takeuchi, & Hamasaki, ; Wu et al, ). Dietary lipid sources and levels exert great effects on growth performance (Yang et al, , ), survival, feed utilization, antioxidant defense, immunity and disease resistance in different aquatic animals (Ma et al, ; Sheen & Wu, ; Wang, Chen, et al, ). Fish meal and fish oil are the best lipid sources for aquacultural feed.…”

A combination of vitamins C and E alleviates oxidized fish oil‐induced hepatopancreatic injury in juvenile Chinese mitten crabEriocheir sinensis

Dietary lipid oxidation is a lasting concern to aquafeed manufacturers and aquaculture farmers. Here, we determined if there was an association between oxidized fish oil (OFO) and hepatopancreatic injury in Chinese mitten crab, and evaluated the alleviating effects of a combination of vitamins C and E on hepatopancreatic injury. There were significant reductions in the body weight gain, hepatopancreatic index, and feed efficiency in crabs that received OFO. Diets with OFO also resulted in reduced crude fat contents in the hepatopancreas and muscle tissues, and alternations in the hepatopancreatic fatty acid compositions, especially a reduction in polyunsaturated fatty acids. Moreover, dietary OFO exposure reduced the antioxidant defense and non‐specific immune response, caused hepatopancreatic injury, and even apparent whitening. An ultrastructural examination of the whitened hepatopancreas revealed that hepatopancreatic cells were injured at varying degrees following OFO exposure. The combination of vitamins C and E could efficiently maintain a constant fatty acid profile in the hepatopancreas exposed to OFO, thus alleviating OFO‐induced hepatopancreatic injury. In addition, a biochemical analysis indicated that a combination of vitamins C and E not only improved the antioxidant status by mitigating the harmful effects of oxidized oil, but also modulated non‐specific immune responses in the crab that received OFO. Overall, OFO‐induced hepatopancreatic injury may be alleviated by a dietary combination of vitamins C and E, and the feeding of rancid forage fish or diets that contain highly oxidized oil is likely a cause of hepatopancreatic necrosis that is frequently observed in farmed crabs.

“…The main components of ROS triggered by toxicants include superoxide anion, H 2 O 2 , and OH − radical (Malhotra and Kaufman, 2007). Simultaneously, the T-AOC content following toxin exposure expresses the total antioxidant capacity originating from enzymatic and nonenzymatic systems (Yang et al, 2015). Thus, the increased contact and absorption of toxicants from the environment in fish gills leads to an increased rate of toxicant metabolism in this organ and the generation of superoxide anion, H 2 O 2 , and OH − radicals, which may lead to ROS accumulation (Malhotra and Kaufman, 2007).…”
