| Abstract: | At three different water temperatures(150175and 190),the results of the growth and Survival rate of larvae in each experimental group were obtained as following:63m/d.86m/d93m/d;610%705%and 230%respctively.22 days after the substrates were given,the average size(length times height)of juvenile in each group were measured:620m595m705m680m and 745m710m;The average growth and survival rate were 177m/d216m/d and 234m/d;354%343% and 123% respectively.The results of experiments were analysed and showed that the water temperature of 175 were better than other temperature. |
