Effect of Water Temperature on Survival, Growth and Intermolt Period of Tiger Crab, Orithyia sinica (Linnaeus) Larvae

2004

In the present study, the effect of different water temperature (15, 20, 25, and ambient) on survival, growth rate and intermolt period of zoeal and megalopal stage of tiger crab, Orithyia sinica were examined. The survival rate of zoeal and megalopal stages of experimental crab was observed high at and ambient water temperature. The growth rate of crab larvae showed temperature-dependent increase. Therefore, the maximum growth rate was recorded at temperature-regulated group in both zoeal and megalopal stage. However, temperature-dependent decrease in larval stages of crab during intermolt period has been observed in the present investigationऐ돀졽�⨀堘�⨀ꢐ�⨀돐좐�⨀��⨀킐�⨀뤏덐�⨀렏頏࢑�⨀਀࢑�⨀ᢑ�⨀؀ကᢑ�⨀?୩Ѐက䂑�⨀䂑�⨀
