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 in worm numbers and in productivity per kg DM and crude protein of added substrate. Relative growth in numbers and in weight of the worms was similar on manure derived from buffaloes and cattle.

The negative effect of water hyacinth was greater with buffalo than with cattle manure. Residual compost from cattle manure was richer in N and poorer in ash than compost derived from buffalo manure. Water hyacinth added to the substrate resulted in compost with less N but more ash.

The second study included two experiments. The first experiment was on the growth performance of Marble goby and Tra catfish fed diets of trash fish and rice field prawns replaced (on an iso-nitrogenous basis) with 0, 25, 50, 75 and 100% of frozen earthworms (Perionyx excavates).

The weight gains of Marble goby and Tra catfish, and the survival rate of the Marble Goby, decreased markedly with curvilinear trends as the proportion of frozen earthworms in the diet was increased (Experiment 1). The Tra catfish appeared to adapt better than the Marble goby to the frozen worms.

The second experiment, which was designed to test the hypothesis that the poor growth rates with frozen earthworms were due to the low palatability of the earthworms after being frozen, confirmed the negative effects of this method of conservation.

Growth rates were 4 and 2 times greater for Marble goby and Tra catfish, respectively, when they were fed fresh rather than frozen earthworms. Survival rate was 100% on the fresh earthworm diet…..

    Formulating fish feed using earthworms as a protein source

    Formulated feeds are complete feeds which supply all the nutrients necessary for optimal growth and health of the fish in culture practices. In many areas of the world protein sources are scarce and for formulating aquafeeds earthworms as a protein source might provide an alternative to common used raw materials.Earthworm: Good nutrition in an animal production system is essential to economically produce a healthy, high quality product. Nutrition is critical because it represents 40% to 50% of operational and production cost. Fish nutrition has advanced dramatically in recent

    Partial replacement of fish meal by earthworm meal

    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

    Earthworms – An animal feed alternative

    Using insects as an alternative to the conventional animal feed has been researched for quite some time now, ranging from flies to insect larvea, this new alternative could be the answer to the ever increasing price of animal feed. Now Earthworms - An animal feed alternative are being bred as an alternative feed source, and the waste is being seen as a rich fertilzer. A win-win some would say. Earthworms - An animal feed alternative Most farmers apply fertilizers and all kinds of manure such as human waste and animal urine on their farms to improve production. They also mulch as an

    Role of earthworm on earth

    Composting worm Role of earthworm on earth - Earthworm production systems involving waste management are evolving and are in the growth phase where emphasis is upon marketing, inoculum and vermicast. As the industry matures there will be a need to change the marketing emphasis from “the worm as an inoculum” to “the worm as a value-added marketable product”. Very large quantities of worm products will be available if production systems are designed and managed appropriately. Role of earthworm on earth are recognised as an effective and environmentally sound method of increasing the rate
