An evaluation of three annelids as feed ingredients in formulated diets for juvenile Penaeus monodon

Abstract

The nutritive value of two species of earthworms, Eisenia foetida and Eudrilus euginae and the marine annelid, Nereis sp. in P. monodon juvenila diets was determined in two separate experiments. Percentage weight gain and survivla were higher with diets containing Eisenia foetida compared to those of diets with Nereis sp. Diets containing dried worm meal were also better compared to those with frozen worms incorporated in the "wet" form. Incorporation of earthworms at 10% level in the diets improved growth and survival when compared to a control diet. When 30% of Eudrilus euginae was used to replace fish meal in the diet, weight gain and survival of animals were higher compared to those of diets with fish meal.
