水文气象因子变化对自然海区对虾早期生命的影响

EFFECTS OF VARIATION OF HYDROLOGICAL AND METEOROLOGICAL FACTORS ON EARLY LIFE OF WILD SHRIMP(PENAEUS CHINENSIS)

利用渤海湾对虾卵子、幼体和幼虾调查资料 ,引用相对成活倍数的概念 ,并选择与对虾早期生命有因果关系的水文气象因子 ,通过相关分析方法分析讨论了水文气象因子变化对对虾早期生命的影响。结果表明 ,6～ 7月盐差。

Based on the investigation data of the shrimp(Penaeus chinensis)egg, larva and juveniles in the Bohai Bay, the concept of relative survival times was quoted and the hydrological and meteorological factors which have an effect on the shrimp early life were chosen. By using the correlative analysis method, the effects of variation of the hydrological and meteorological factors on the shrimp early life were analyzed and discussed.The results showed that the salinity differences between June and July, the water temperature of shrimp spawning grounds in the mid-May and Yellow River runoff have an obvious influence on the shrimp early life.
