Two feeding trials were conducted to study the effects of two types of artificial feeds and natural diets on the growth and survival of Penaeus monodon postlarvae. In Experiment I Penaeus monodon postlarvae PL1 were reared in two litre round bottom flasks at a stocking rate of 50 postlarvae per litre. The shrimps were randomly assigned to five different diets freshly hatched Artemia nauplii commercial flakes a 50-50 combination of flakes and Artemia nauplii commercial crumbles and a 50-50 combination of crumbles and Artemia nauplii in duplicates for a 10-day feeding trial. The postlarvae were fed 4 times a day and randomly sampled every other day with a complete water change. In Experiment II the postlarvae PL11 were reared in three litre rectangular plastic bowls for a 24-day feeding trial. Each bowl was stocked with 20 postlarvae. The shrimps were randomly assigned to five different diets cooked mussels commercial flakes a combination of flakes and mussels commercial crumbles and a combination of crumbles and mussels in duplicates. The postlarvae were fed on ad libitum basis three times a day. Samplings for growth and survival were made every other day with a complete sea water change. The results indicated that the perfomance of the two types of feed as 50 replacement was equivalent to the live food for the early nursery stage of P. monodon Experiment I.

Abstract

Two feeding trials were conducted to study the effects of two types of artificial feeds and natural diets on the growth and survival of Penaeus monodon postlarvae. In Experiment I Penaeus monodon postlarvae PL1 were reared in two litre round bottom flasks at a stocking rate of 50 postlarvae per litre. The shrimps were randomly assigned to five different diets freshly hatched Artemia nauplii commercial flakes a 50-50 combination of flakes and Artemia nauplii commercial crumbles and a 50-50 combination of crumbles and Artemia nauplii in duplicates for a 10-day feeding trial. The postlarvae were fed 4 times a day and randomly sampled every other day with a complete water change. In Experiment II the postlarvae PL11 were reared in three litre rectangular plastic bowls for a 24-day feeding trial. Each bowl was stocked with 20 postlarvae. The shrimps were randomly assigned to five different diets cooked mussels commercial flakes a combination of flakes and mussels commercial crumbles and a combination of crumbles and mussels in duplicates. The postlarvae were fed on ad libitum basis three times a day. Samplings for growth and survival were made every other day with a complete sea water change. The results indicated that the perfomance of the two types of feed as 50 replacement was equivalent to the live food for the early nursery stage of P. monodon Experiment I. However only the crumbles 50 or 100 replacement performed well for the later nursery stage of P. monodon Experiment II.
