“…Soybean oil is rich in 18:2n‐6, which is very hard to dilute when deposited in tissues, so totally replacement of soybean oil will result in the essential fatty acids being unbalanced, as well as poor growth of aquatic animals. The result is similar to other research conducted by Montero et al () and Chen et al (). Therefore, partial replacement of fish oil by vegetable oil (FO/VO) may be beneficial to the biological characteristics of aquatic products.…”

Five different diets with different ratio of fish oil to vegetable oil were prepared. The biological index and proximate composition of Eriocheir sinensis fed with different diets were compared, and then sensory analysis, electronic nose (E‐nose) and headspace‐solid phase micro‐extraction combined with gas chromatography‐mass spectrometer (HS‐SPME‐GC‐MS) analysis were applied to determine the odor profile of E. sinensis. The results showed that partial replacement (50%–75%) of fish oil by vegetable oil (FO/VO) was beneficial to the weight increment, nutrition accumulation, and odor‐active compounds (OACs) formation of E. sinensis. A total of 7 and 11 OACs were detected in the hepatopancreas and gonad, respectively, these OACs contributed greatly to the overall odor profiles of E. sinensis when the dietary replacement levels were at 50% and 75%, respectively. The results could provide the guide for dietary fish oil replacement as well as improving the odor quality of E. sinensis. Practical application The objective of this research is to compare the effects of dietary replacement of fish oil by vegetable oil on proximate composition and odor profiles of E.sinensis. The results obtained from this study would not only chose an optimal dietary replacement level and serve as a useful database for the odor of female and crabs, but also provide some guide for the improvement of Chinese mitten crab aquaculture.

“…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, ).…”

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

et al. 2019

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.

“…However, the relatively constant global supply of FO will soon be insufficient to feed the rapidly growing aquaculture industry (Tacon & Metian, ). Supply shortages and increased prices have encouraged research into vegetable oils and animal fats as alternative dietary lipid sources (Chen et al., ; Nayak, Saha, Pardhan, Samanta, & Giri, ; Sun, Ye, Chen, Wang, & Chen, ).…”

This study investigated the effects of dietary lipid sources on juvenile blunt snout bream, Megalobrama amblycephala. Juvenile blunt snout bream (14.40 ± 0.01 g) were fed diets containing 75 g/kg of fish oil (FO), linseed oil (LO), soybean oil, coconut oil (CO), rapeseed oil or beef tallow (BT) for 9 weeks. Survival rates, final weight, weight gain, feed efficiency ratio and feed intake remained unchanged. Viscerosomatic ratio, hepatosomatic index and condition factor were highest in fish fed the CO diet (p < 0.05). Whole‐body lipid content decreased, whereas liver lipid content increased in fish fed CO and BT diets (p < 0.05). Eicosapentaenoic acid and docosahexaenoic acid in the muscle and liver increased in fish fed the FO and LO diets (p < 0.05). FO and LO diets increased plasma glucose (p < 0.05). Feeding CO diet increased hepatic fatty acid synthase (FAS) and acetyl‐CoA carboxylase expression, and FAS activity (p < 0.05). Both CO and BT diets increased hepatic carnitine palmitoyltransferase I (CPT I) and carnitine palmitoyltransferase II expression, and CPT I activity compared to the FO diet (p < 0.05). These results indicate that LO can be substituted for FO in juvenile blunt snout bream diets without negative effects.
