Effects of Temperature,Salinity and Density on the Growth and Survival in Spats of Clam(Ruditapes philippinarum)
摘要
Abstract
To identify the effects of temperature,salinity and density on the growth and survival of Ruditapes philippinarum larvae,an economically important mudflat shellfish in China,a model of clam growth and survival under different environmental conditions was constructed and analyzed with response surface method in this study.Three factors(temperature,salinity and density)and three levels(-1,0 and 1)were designed to investigate the effects of temperature,salinity and density and their interactions on the growth and survival of clam larvae,with the shell length of larvae as the response value.The study showed that after 73 days of incubation,the secondary effects of temperature,salinity and density on the growth of shell length of clam larvae were highly significant(P<0.05).With the increase of temperature,salinity and density,the shell length growth of clams showed a trend of increasing and then decreasing,it showed parabolic characteristics,of them the effect of salinity on the shell length growth of juvenile clams was highly significant(P<0.01).However,no interaction among the three factors on the shell length growth of clams was significant(P>0.05).The quadratic multinomial regression equation for the predicted shell length(Y)corresponding to the independent variables of temperature(T),salinity(S)and density(D)was Y=-6.331 05+0.276 5T+0.573S+0.689D-0.005 66T2-0.013 7S2-0.115 9D2.The growth models of clam fry species under different environments were constructed by the quadratic response surface regression equation.The optimum growth environment for the spats was obtained as temperature(24.32 ℃),salinity(21.13),and density(2.88× 104 ind/m2),and the average shell length of the spats could reach the maximum(4.07 mm)under these conditions.关键词
