摘  要：
选取黄河口优势种四角蛤蜊为受试生物,采用半静水实验法研究高盐胁迫对四角蛤蜊摄食与生长的影响,并探讨了高盐胁迫对贝类摄食与生长影响的盐度阈值。结果表明,高盐胁迫对四角蛤蜊的摄食与生长都有显著影响,四角蛤蜊壳长和体重的日均增长量以及适应胁迫后的摄食率均随盐度的升高而逐渐降低;而盐度突变时的摄食率随盐度的增加呈先升高后降低的趋势。通过显著差异性分析,发现显著影响四角蛤蜊摄食的盐度阈值范围为26～28,显著影响生长的盐度阈值范围为22～24,最终确定高盐胁迫对黄河口四角蛤蜊摄食与生长的影响阈值为22～24。

摘  要：
The Yellow River estuary is a major fishery and spawning ground in the Bohai Sea.With the decrease of Yellow River runoff,the salinity of water in the estuary became higher,thus many researches focused on the study of ecological water requirement.In this experiment,we used the local dominant species Mactra veneriformis as target organism to detect the influence of high salinity stress on ingestion and growth by semi-static water.The results showed that,with the increase of salinity,the ingestion rate and daily growth rate of shell length and weight decreased.The ingestion rate increased firstly under sudden changes in salinities,and then increased.Through the One-Way ANOVA analysis,the thresholds of ingestion and growth were obtained as 26～28 and 22～24,respectively.Finally,the threshhold of the high-salt stress on ingestion and growth of Mactra veneriformis was determined as 22～24.
