Marble goby and Tra catfish fed with Earthworm becomes hot tittle for science not only Vietnam, but also worldwide Two studies were conducted at the experimental farm of An Giang University, Viet Nam. Marble goby and Tra catfish fed with Earthworm The first study on the growth of earthworms (Perionyx excavates) was a 2*2 factorial experiment with 4 replicates, in which the treatments were: source of manure (cow or buffalo) and supplementation with water hyacinth at 25% of the weight of manure (DM basis) or none. Adding chopped water hyacinth to buffalo or cattle manure led to a decrease

Earthworm powder as extra fish food. The optimization of protein content in earthworm-based fish feed formulation was investigated in the study Full factorial design (FFD) and central composite design (CCD) were used as a statistical tool to screen the range of the selected parameters and to optimize the process respectively Three components were combined in the fish feed formulation namely earthworm powder chicken guts and soybean waste as the protein source The optimum nutritional values were obtained at 25% 25% and 595% for earthworm powder soybean waste and chicken guts

Full Length Research Paper Partial replacement of fish meal by earthworm meal (Libyodrilus violaceus) in diets for African catfish, Clarias gariepinus Fish meal is the most common source of protein for aqua feeds. However, the cost of fish meal is on the rise, because of its competing use as feed ingredient by other animals (livestock, ruminants etc.). It is therefore necessary to find alternatives to fish meal in the preparation of animal diets.Various workers have attempted to use other locally available cheap protein sources (e.g. plant protein, agricultural by- products, fishery
