菲律宾蛤仔摄食率与温度、壳长和饵料浓度的关系

Effects of water temperature, shell length and the concentration of algae on the ingestion rate of Ruditapes philippinarum

中文摘要:

      以等边金藻3011为饵料，采用室内流水法，在12、20和24 ℃3个温度和不同的壳长、饵料浓度下，测定并计算了温度、壳长和饵料浓度与菲律宾蛤仔摄食率的关系，并建立了相关数学模型。结果显示，在实验条件范围内，摄食率随着饵料浓度的增大而增大，且符合幂函数方程。摄食率可以用温度、壳长和饵料浓度的自然对数方程表示，其模型为：IR=21.2LnT+20.06LnL 7.10LnC-97.95，经协方差分析结果表明，其相关系数呈非常显著水平。

英文摘要:

      The ingestion rates of Ruditapes philippinarum fed with Isochrysis galbana3011 under simulated conditions were studied. Moreover, investigation of the relationship between feed ingestion and temperature (12 ℃、20 ℃ and 24 ℃), shell length and algae concentration was carried out, and some mathematic models about the factors were set up. It was found that the ingestion rate was positively correlated with the algae concentration, and the ingestion rate of Ruditapes philippinarum correlated with them by the allometric equations. The impact of temperature, shell length and algae concentration on ingestion rate could be described by the following model: IR=21.2LnT+20.06LnL 7.10LnC-97.95, and analysis of covariance showed that the coefficient of correlation of the model was significant (P<0.01)
