Pemberian Hormon Fitoekdisteroid (Vitomolt) Pada Pakan Alami Terhadap Sintasan Larva Rajungan (Portunus pelagicus) Pada Stadia Zoea - Megalopa.
Abstract
The purpose of this research of find out the effect of enrichment natural feed rotifer
(Brachionus plicatilis) and Artemia sp with fitoekdisteroid (vitomolt) in difference doses to
survival rate of blue swimming crab larva (Portunus pelagicus)The experiment design was
used completely randomized design with 4 treatments and 3replications the treatments
fitoekdisteroid, there were : P1 = 0 mg/L, P2 = 1 mg/L, P3 = 2 mg/L, P4 = 4 mg/L.The result
of research showed that eneichment of natural feed rotifer (Brachionus plicatilis) and
Artemia sp with fitoekdisteroid (vitomolt) gives significant effect to the survival rate of blue
swimming crab larva. The highest survival rate affects on P3 treatments with 2 mg/L are
5,91% and the lowest are P4 treatments with 4 mg/L are 1,64%.The development of crab
larvae (Portunus pelagicus) from zoea-I to megalopa requires 14-16 days.
