Abstract

Abstract

The reproductive season,embryo development and larval culture of amphioxus in the National Natural Protective Area of Xiamen were studied in detail by the methods of histology and embryology.The results indicate that the reproductive season of amphioxus in the National Natural Protective Area of Xiamen maybe divided into two breeding stages.One is the breeding peak stage which starts from June to the end of July,and another is small breeding stage which is in August and September.The observation on the artificial breeding suggests that amphioxus spawned initially at about 07:00 PM,and the spawning and spermiation behaviours in female and male amphioxus could be seen.The male amphioxus left firstly the sand,rushed up to the water surface,and swam as well as released sperms.Then,the fmale swam to the water surface,and all eggs passed out from broken wall of ovary into the at rial cavity and through the atriopore to the water.The fertility rate is about 98.5%.At the same time,the whole process of the development from larvae to young fish is observed with metamorphosis(length:1.05~13.50 mm).
