| Abstract: | The reproductive habit , season and reproduct ive capacity , hatching, development and
metamorphosis of larva, and development course of naiad and young Rapana venosa were studied in
this paper. It s reproductive period is from June to August ( 19- 26 e ) every year in inshore of
Shandong . The parents mate many times in a reproductive period. The female spawns 2. 1 times and
lays 655. 9 egg bags in average every reproductive period. The individual reproductive capacity is 754
thousants in average. There are average 1149 zygotes in a egg bag. Under 21- 22 e , the religer larva
hatched af ter 20- 26 days. Hatching rate is 80. 8% . After 26- 30 days, the larva developed into
naiad and grew into young snail after 57 days. |
