survival of Angel fish, Pterophyllum scalare (Lichtenstein) larvae using defatted
clam meat powder as the chief protein source was studied. One-day-old
free-swimming hatchlings were used in the investigations done for a period of 21
days. The different diets used were with 24.91 %, 29.83%, 34.72%, 39.86%,
44.79%,49.85% and 54.63% protein levels with 3 replicates for each treatment.
The results showed that the growth of larvae in terms of gain in length,
gain in weight and specific growth rate was maximum for the diet with 44.79%
protein level. From the relationship established between protein level and SGR,
the optimum level of protein attaining maximum SGR (21.163) was found to be
53.099%. No significant difference was found in the survival rate of larvae fed
with different diets. Thus artificial diet with 44.79% protein level can be used
efficiently for rearing Angel fish larvae.
