Effects of Different Biological Diets on Reproductive Performance and Offspring Quality of Horseshoe Crab(Tachypleus tridentatus)
The aim of this study is to identify biological diets that effectively enhance gonadal development and spawning in T.tridentatus.Five groups of biological diets were administered to T.tridentatus,comprising Ruditapes philippinarus(A),Perinereis bidentata(B),Ostreagigas(C),R.philippinarus+P.bidentata combination(D),and Ostreagigas+P.bidentata combination(E).The effects of different diets on the quality of offspring were analyzed by comparing the egg diameter,hatching rate and the width of the first-age larva's cuticle,and the effects of different diets on reproductive performance were evaluated.The results showed that the number and frequency of spawning in group D were higher than those of other test groups,followed by group E,and the number and quality of spawning in mixed test group were higher than those of single test group.R.philippinarus and P.bidentata are more suitable for the development of parent T.tridentatus gonadal enhanced culture,which can significantly promote the gonadal development and spawning.The conclusion of this study provides reference for the development of safe,efficient and high-quality gonadal ripening food for T.tridentatus.
