| 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；低于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

| Abstract: | 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°C to 30°C 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°C or above 26°C as the suitable temperature for embryo development is 15 - 25°C. In the pluteus stage, it can not develop and metamorphosis normally at temperature lower than 15°C or above 24°C. It develops normally at nearly 20°C. The young sea urchin stage can not live at temperature lower than 0°C or above 30°C and the suitable temperature of growth is 16 - 22°C. The adult sea urchins were alive at 0°C, but the movement was very weak and the growth was slow; at 30°C they all died. The suitable temperature is 10 - 24°C. In the above growth stages the temperature adaptability of pluteus is the weakest and that ol the adult sea urchin is the strongest. |
