Abstract: In this study,effects of culture method(in a bottom-covered with sand tank and a plastic net),stocking density(50-250 ind./m2),and food type(Sargassum thunbergii meal,Sargassum sp.meal,kelp Laminaria japonica meal,fish meal and shrimp meal)on growth and survival of rock-worm Marphysa sanguinea with average body weight of(6.26±1.68)g were studied to optimize the conditions of artificial breeding and culture.The results showed that a plastic net suspanded breeding method had better growth and high survival rate of 88.6%in 30 day culture.The survival rate of 86.7%was observed at stocking density of 50 ind./m2and 100 ind./m2,significant different from those at stocking density of 150,200 and 250 ind./m2in 60 day culture(P＜0.05),with the suitable stocking density from 113 ind./m2to 125 ind./m2(705-750 g/m2)for artificial breeding.The diet containing 30%-70%of animal protein or fresh Artemia met the requirements of rock-worm for growth.The findings will provide the basic data supporting for artificial induction of maturity and aquaculture of rock-worm.
