Comparation of the Improvement Effect on Body Colour of Chinese Mitten Crab Caused by Three Carotenoid Sources
摘要
Abstract
This study was conducted to compare the improvement effect on body colour of Chinese mitten crab caused by three carotenoid sources,in order to provide a reference for optimizing quality of Chinese mitten crab. Four experimental diets were formulated,including a control diet and three diets in which adding 2.00%Spirulina,0.55% Haematococcus pluvialis and 15.00% alfalfa meal,respectively,and the content of carote-noid in those diets was 6.0,67.2,67.6 and 49.5 mg/kg,accordingly. Two hundred and forty Chinese mitten crabs with the initial body weight of(8.9±0.3)g were stored in 16 tanks with 15 crabs per tank. Each diet fed crabs in 4 tanks for 60 days. The results showed as follows:at the end of the feeding trial,no significant differ-ences were observed in final body weight,survival rate and specific growth rate among all groups( P>0.05). The contents of carotenoid and astaxanthin in both carapace and hepatopancreas were successively increased in Spirulina,Haematococcus pluvialis and alfalfa meal,and were significantly higher than those in control group ( P<0.05). Moreover,the contents of carotenoid and astaxanthin in both carapace and hepatopancreas in alfalfa meal group were significantly higher than those in Spirulina group(P<0.05). These results indicate that the body colour of Chinese mitten crab can be improved by Spirulina,Haematococcus pluvialis and alfalfa meal, and the alfalfa meal has the best effect.关键词
