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

Composting worms not only need food, but also some sort of habitat to live in – Earthworm compost bedding materials provide both. What is Earthworm compost bedding Ideal worm living conditions can be created initially by adding lots of bedding material with a decent amount of waste material (and likely some water to ensure adequate moisture conditions). People often refer to the ideal composting moisture content as being similar to that of a wrung-out sponge. Higher moisture levels do tend to work better for worm composting, but this is definitely a good guideline to start with (esp

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
