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…..

    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

    How To Harvest Earthworm

    How To Harvest Earthworm is easyer than anything else before you thought before... When to harvest earthworm Generally, a worm bin will have produced a significant amount of good vermicompost at between two and three months along in the process. If you wait even longer, like 4-6 months, you'll have more finished looking vermicompost (it will look more like soil and have more plant-ready nutrients in it). Tip - Try harvesting early one time, then letting it go for much longer the next time, so that you can see the difference in finished product. Harvesting Methods - How To Harvest

    Including Earthworm in Organic Poultry Diets is widenly applied in worldwide agriculture.... Introduction Including Earthworm in Organic Poultry Diets Including Earthworm in Organic Poultry Diets It is common for free-range chickens to consume earthworms. Earthworms are very efficient at converting plant and animal wastes into biomass that can be used as a feed ingredient in animal production: a ton of animal wastes will produce about 100 kg of worms (Edwards, 1985). Earthworms are a good quality protein for use in animal feeds, but the practical use of earthworm meal is influenced by
