摘　　要：于1988—1990年进行水温(0—30℃)对光棘球海胆不同发育阶段的影响的试验。结果表明,水温对光棘球海胆各发育阶段的生长等均有显著影响,并且,不同发育阶段对水温的要求不同。其中,低于5℃或者高于26℃时,受精卵不发育;低于15℃或者高于24℃时,浮游幼体发育不正常;低至0℃或者高至30℃时,幼海胆难以生存,生长适温在16—22℃;成海胆,0℃时活力显著减弱但短期内无死亡,30℃则大量死亡,生长适温在10—24℃。各发育阶段以浮游幼体期对水温的适应能力最弱,成海胆期适应能力最强。The effect of temperature on sea urchin, Strongylocentrotus nudus A., development in the embryo, pluteus, young and adult stages was studied.The test carried out in 1988-1990 at temperatures from 0℃ to 30℃ showed that the effect of temperature on sea urchin development is apparent in the above growth stages and that zygotes can not be divided normally at the temperature lower than 5℃ or above 26℃ as the suitable temperature for embryo development is 15-25℃. In the pluteus stage, it can not develop and metamorphosis normally at temperature lower than 15℃ or above 24℃. It develops normally at nearly 20℃. The young sea urchin stage can not live at temperature lower than 0℃ or above 30℃ and the suitable temperature of growth is 16-22℃. The adult sea urchins were alive at 0℃, but the movement was very weak and the growth was slow; at 30℃ they all died. The suitable temperature is 10-24℃. In the above growth stages the temperature adaptability of pluteus is the weakest and that oi the adult sea urchin is the strongest.
