In order to know the energy requirement of prawn (Penaeus japonicus) larvae under feedingconditions of Brachionus plicatilis and Artemia sp. nauplii, daily consumption rate of those foodorganisms by prawn larvae at different developmental stages was observed. Prawn larvae werereared individually from 2nd zoea to 2nd post larva stage at food density of 10 ind・ml^ forrotifers and 5 ind・ml^ for Artemia. The consumption rate of rotifers per larva increased to 308ind・larva^・day^ until 3rd zoea stage. After 1st mysis stage, the consumption rate decreased.The consumption rate of Artemia was almost constant at 50 to 80 ind・larva^・day^ until 3rdmysis stage. In 1st post larva stage, Artemia consumption increased about 1.6 times as that of3rd mysis stage. Energy intake rate per larva was 0.60 cal・larva^・day^ at 3rd zoea stage in thefeeding conditions of both rotifers and Artemia. After 1st mysis stage, the intake rate of rotiferdecreased gradually. However, the intake rate of Artemia increased to 1.26 cal・larva^・day^ in2nd post larva stage and about 3 times as that of rotifer feeding. |
