Influences of starvation on the development, ingestion and survival of Panulirus stimpsoni phyllosoma(Ⅰ)

The results of the study on the growth,development,ingestion and survival of P.stimpsoni phyllosoma (Ⅰ)under the condition of starvation show that they have a high ability in bearing starvation.After 144 h of complete star vation,the survival rate of phyllosoma is 100%,and 55% of phyllosoma could feed still.After 192~216 h of starvation,although the survival rate of the phyllosoma is 76%~68%,but no phyllosoma could catch food organism any more.Delaying the feeding time about 24~36 h,there is no obvious influence on the growth of phyllosoma.The early phyllosoma which were starved for 1~5 d can feed the Artemia sp.nauplius,whose body length is 1/2~1/3 body length of phyllosoma,this phenomenon is not often seen in crustacean phyllosoma.When the phyllosoma store up more enough of nutrition,after had been fed about 60 h,their metamophosis process could remained normally,even though without feeding anythings.According to the effects of intermit tent feeding,it shows that there are no obvious influence on the metamorphosis of phyllosoma.which were feeding after an interval of 8,16,24 h.The results of these observations may provide some referential meaning on the study of lobster's basic biology,artificial breeding and improving the survival rate of artificial breeding.
