海洋滤食性贝类摄食率影响因子研究现状

The present researching status of ingestion rate's influence factors of marinesuspension-feeding shellfish

摄食率IR(Ingestion rate)是反映滤食性贝类生理状况的一项动态指标,它直接受到贝类所处环境的生物和非生物因子的影响。国外对滤食性贝类摄食生理生态的研究报道很多,特别是对几个环境因子,如海水的温度、盐度、pH、流速以及饵料的结构和浓度对摄食生理的影响进行了广泛而深入的研究。国内对于这方面的研究近几年也逐渐趋热。

IR（Ingestion rate）is a dynamic index, which reflects physiology condition of suspension-feeding shellfish and is directly affected by biologic and abiological factors of mollusks＇ living environment. The studies on physiology and ecology of suspension-feeding shellfish were comprehensive abroad, especially in the aspect of environmental factors such as temperature, salinity, pH, velocity of flow, the structure and concentration of bait. Recently,study in this field becomes a hot spot at home. This paper summarizes these research results.
