【摘要】 初步研究了盐度对近江蛏的成活及生长的影响。在盐度梯度为5、10、15、20、25、30的试验水中:近江蛏的潜泥速度在5～20盐度范围内基本相同,3分钟内全部下潜,高于20潜泥缓慢。成活率在盐度5～20范围内差别不大,均在84%以上,高于20成活率显著降低,直至死亡。更多还原

【Abstract】 The influence of salinity on the survival and growth of Sinonovacula rivularis was studied in the water bodies whose salinity was 5,10,15,20,25,30 respectively,and the result indicated that in the waters whose salinity was between 5 and 20,the speed of submerge and the survival rate of the shellfish was stable,when the salinity was higher than 20,both the survival rate and the submerge speed decreased apparently.更多还原
