摘　　要：为比较文蛤红壳色选育系与江苏野生群体在不同条件下滤水率的差异并找出文蛤最佳滤水率条件,采用了试验生态学方法和响应面法对文蛤红壳色选育系幼贝进行滤水率的研究。试验结果显示,在一定范围内,文蛤幼贝滤水率随盐度、温度和藻类密度的增加而增大,超过一定范围,幼贝滤水率随盐度、温度和藻类密度的增加而减小;在同等条件下,文蛤红壳色选育系幼贝与野生群体滤水率无显著差异,但文蛤红壳色选育系生长速率显著高于野生群体;通过响应面法优化,文蛤红壳色选育系幼贝的最佳滤水率条件为:盐度21.82、温度27.40℃、藻类密度9.96×10^4个/mL,此条件下滤水率的预测值为1.62 mL/(个·min)。In order to compare the filtration rate between the selected line of red shell colored hard clam Meretrix meretrix and wild hard clam and optimize the culture condition of juvenile mollusk,we analyze the filtration rate of juvenile mollusk by the experiment ecology method and response surface method.The results showed that with the increase of salinity,temperature and the concentration of algae,the filtration rate of juvenile mollusk was increased first and then decreased.Under the same conditions,there was no significant difference in the filtration rate between the selected line of red shell colored clam and the natural clam,but the growth rate of the selected line of red shell colored clams was significantly faster than that of the wild hard clam.Through the response surface method optimization,the best filtering rate was observed in the clam cultured under the conditions of salinity of 21.82,temperature of 27.40℃,and the concentration of algae of 9.96×10^4 ind/mL.The filtering rate of the predictive value was 1.62 mL/(ind·min)under this condition.
