Effects of Flammulina velutiper mushroom dregs on the growth performance of Ctenopharyngodon idellus
In order to explore the effects of different levels of golden mushroom(Flammulina velutiper)dregs on the growth performance of grass carp(Ctenopharyngodon idellus),and to assess the optimum level of use of golden mushroom dregs in grass carp aquaculture.The experiment was conducted with 600 grass carp in healthy condition weighing about 20 g.The fish were randomly divided into 4 groups with 3 replicates of 50 fish in each group.Each group was fed with a test diet containing 0％(control group),4％,8％and 16％of the mushroom pomace,respec-tively.The experimental grass carp were domesticated for 2 weeks and the formal test period was 8 weeks.At the end of the test,the growth performance indexes of grass carp in each group were statistically analyzed.The test re-sults showed that the feeding of grass carp with 8％golden mushroom dregs significantly increased the test end weight(P＜0.05),weight gain rate(P＜0.05),and significantly reduced the feed coefficient(P＜0.05),in which the test end weight was significantly increased by 6.6％,the weight gain rate by 8.96％,and the feed coeffi-cient was reduced by 6.76％.Whereas,different levels of golden mushroom dregs did not significantly(P＞0.05)affect the data of specific growth rate,liver-body ratio and dirty-body ratio of grass carp.The study showed that the addition of appropriate amount of golden mushroom dregs in grass carp aquaculture production can improve the growth performance and feed utilization of grass carp,and the optimum level of golden mushroom dregs addition is 8％.
