“…The ratio of soybean oil to rapeseed oil was 1:1, but the dietary replacement levels were different in the five diets. (He et al, 2017). In summary, his of both female and male crab were the highest when the replacement level was 75%, with no significant influence on the GSI of male crabs, while the GSI of female crabs was significant higher than other groups when the replacement level was 50%.…”

“…However, the influence on GSI of female crabs was different from our study, as it showed ascending tendency with the increase in replacement level which may be caused by different sampling time. During the fattening period, gonad developed rapidly, while HSI declined with the gradual increase in GSI (He et al, ). In summary, his of both female and male crab were the highest when the replacement level was 75%, with no significant influence on the GSI of male crabs, while the GSI of female crabs was significant higher than other groups when the replacement level was 50%.…”

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.

“…Many studies have shown that the precocity of crabs is mainly caused by the over‐nutrition and high cumulative temperature of the environment in which they grow (Chen, Cheng, & Wang, ), and the difference in proximate chemical composition caused by different living environments may be mainly reflected in the hepatopancreas and gonads. He et al () reported that the differences in proximate chemical composition between wild‐caught and pond‐reared crabs were mainly observed in hepatopancreas and ovary. In our study, the differences between precocious and normal crabs were also mainly reflected in gonads and hepatopancreas, and performing higher protein but lower lipid contents in gonads and hepatopancreas of precocious crabs.…”

The nutritional values of edible gonad, hepatopancreas and muscle tissues from normal and precocious adult male Chinese mitten crabs (Eriocheir sinensis) were investigated herein. The results showed that the average weight and meat yield (MY) of normal crabs were significantly higher than those of precocious crabs, while the hepatopancreas indexes (HSI) and gonadosomatic indexes (GSI) had no significant differences. Precocious and normal crabs had greater protein and lipid contents, respectively, and the differences were mainly reflected in gonads and hepatopancreas. While assessing the amino acid profiles, both precocious and normal crabs could be high‐quality protein sources, particularly the precocious crabs which showed higher levels of essential amino acids. In fatty acid profiling experiments, precocious crabs revealed higher EPA, ∑n‐3 polyunsaturated fatty acids (PUFA) and ∑n‐3/∑n‐6 ratios than normal crabs; however, DHA and ∑n‐6 PUFA contents were considerably lower. Additionally, contents of nutritious minerals K and Ca in precocious crabs were significantly higher than those in normal crabs, while Zn and Fe were significantly lower. In short, our data indicated that precocious Chinese mitten crabs are also a nutritious food, and even in some respects their nutritional value is higher than normal crabs.

“…The swimming crab, Portunus trituberculatus , is a commercially important marine crab along the coasts of East Asia. The species has a high market demand due to its large size, unique flavour and high nutrition value (He et al, ; Wang et al, ). Due to overfishing and the deterioration of coastal environment, the fisheries production of the crab cannot keep pace with the growing market demand.…”

A 120‐day trial was conducted to assess the effects of dietary fish oil replacement with vegetable oils on growth, lipid metabolism and antioxidant capacity of subadult swimming crab Portunus trituberculatus. Five isonitrogenous and isolipidic diets were formulated to replace 0, 250, 500, 750 and 1000g/kg of fish oil with a mixture of soybean and rapeseed oil (defined as D1–D5), and each treatment had 30 replicate crabs. Dietary fish oil replacement had no significant effects on growth of the crabs, while the D3 had the highest hepatosomatic index and total lipids in hepatopancreas. The triglyceride and lipase activities in hepatopancreas increased significantly with increasing dietary fish oil replacement. The D4 had the highest levels of alkaline phosphatase (ALP) and acid phosphatase (ACP) in the hepatopancreas, as well as the haemolymph ALP, ACP and peroxidase. The highest levels of haemolymph total antioxidant capacity, catalase and malondialdehyde were detected in D1. Total n‐3 polyunsaturated fatty acids levels in hepatopancreas decreased significantly with increasing dietary fish oil replacement. In conclusion, dietary fish oil replacement had no significant effects on growth of P. trituberculatus, and 500g/kg of fish oil replacement could improve antioxidant capacity, but excessive replacement level will enhance lipid accumulation and peroxidation in the hepatopancreas.
