Relationship between diet composition and growth

rate of the zoeal and mysis stages of Penaeus japonicus BATE

C. T. Villegas and A. Kanazawa

Feeding experiments were conducted using Chaetoceros gracilis plus A rtem ia nauplii, a rtific ia lly prepared diet, Diet-B, and tw o commercial feeds, Tapes and mysid meals, in a randomized complete block design w ith tw o replicates. The a rtific ia lly prepared diets were dried and ground to size 10 to 50 microns and fed to the larvae. The larvae were reared in round plastic aquaria containing 5 liters of filtered seawater, each aquarium stocked w ith 250 larvae and provided w ith aeration. They were reared from zoea (Z 1 ) to mysis (M3 ) stage and growth was measured daily.

Highest survival rate of 34.2% was obtained when the larvae were fed w ith the a rtific ia lly prepared Diet-B. C. gracilis plus Artem ia nauplii feeding gave a survival rate of 21.6%. On the other hand, growth measured in terms o f development, was fastest using C. gracilis plus Artem ia nauplii. Larvae metamorphosed into M3 stage in 7 days w ith an average gain in length of 0 .46 mm/day. Diet-B feeding resulted in a comparable growth, the larvae reaching M 3 stage in 8 days w ith an average gain in length of 0.30 m m/day.

Analyses of the chemical com position of the diets showed no definite relationship between diet com position and growth and survival rates of the early larval stages of P. japonicus.

Results obtained in this study demonstrate that the early larval stages of P. japonicus can be reared in a rtific ia lly prepared diet, Diet-B. Since the chemical com position o f the diet is known, it can be used as supplemental data fo r larval feed development and n utrition al requirements studies for the early

larval stages o f P. japonicus and/or other penaeids.
