| 摘 要： | 对虾夷马粪海胆石在１０．０－２５．０℃水温下单独投喂海带，裙带菜、石莼及１５．４－１７．８℃混合投喂海带、裙带菜、石莼、铜藻、角叉菜的不同组合和２１．６－２７．４℃饥饿状态下的摄食、生长及成活进行了试验研究。海胆体重与壳直径的关系为Ｇ＝０．４３１３２Ｄ＾２．９９５８。海胆对海带、裙采、石莼的日摄食率依次降低且随水温变化而异。１．０－３．６ｃｍ的纪海胆在１０．０－２５．０℃下摄食上述海藻均可保持较快

| Abstract: | The feeding and growth of Japanese common sea urchin,
Strongylocentrotus intermedius fed on Laminaria japonica , Undaria pinnatifida and Ulva sp.
in 10.0-25.0and fed on the mixed algae combined with Sargarssum horneri, Chondrus sp. in
15.4-17.8 were determined respectively. The relationship between sea urchin body weight(G)
and test diameter(D) is G=0.43132D2.9958. And the results also showe that the daily feeding
rates of sea urchin fed on the three kinds of algae are different and change with the water
temperature. The daily growth rates are 0.510-2-3.010-2cm/(indday) of juvenile sea urchin
(1.0-3.6cm in test diameter ) fed on L. japonica, U. pinnatifida and Undaria sp. in 10.0-25.0.
The daily relative growth rate is the biggest in 19.0 in the juvenile (1.0cm in diameter),but in 16.
0 for adult (3.6-5.0cm in diameter). The body weight growth rate is negative of adult sea urchin
at 25.0. For 1.0-5.3 cm sea urchin, the ability for antihigh temperature decreases with the
increasing of te The color of body and sex gland of sea urchin vary with its fed algae. It also
indicates that the sequence of selective feeding on five kinds of algae is L. japonica, U.
pinnatifida, S. horner, Chondrus sp., Undaria sp. The result of hungry test shows that the sea
urchin can be hungry for 15 days in 21.6-27.4,and the antihungry ability for 1.7-3.5 cm is
stronger than the others of 1.0-5.2 cm sea urchin. |
