Aquaculture with Earthworm

21-01-2017 Anphu Earthworm Co., Ltd - Solution for organic agriculture

Two studies were conducted at the experimental farm of An Giang University, Viet Nam.

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…..Read more: Nhi_N_100909

    The Useful Of Earthworm Powder For Human Care!

    Hisashi MIHARA Hiroyuki SUMI Hideaki MIZUMOTO Tomoyuki YONETA Ryuzo IKEDA and Masugi MARUYAMA _________________________ Department of Physiology Miyazaki Medical College Kiyotake, Miyazaki INTRODUCTION The history of use of the earthworm as a therapeutic drug source for various diseases extends back for several thousand years in China and other parts of the Far East. However, practical pharmacological studies have not been performed except on lumbrofebrin as an antifebrile (1). In 1983, we reported that very strong and novel fibrinolytic enzymes could be extracted from the

    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

    Earthworm-Water Hyacinth Project

    From 2012, Anphu earthworm Co.,Ltd has launched campaign to help poor farmer along river to take water-hyacinth to raise earthworm. By collecting water-hyacinth from river then put into pp pack, after 10 days, bring home and keep in dry and lean-to. Then put vermiculture (earthworm) into pack about 5kg. after 40 days the worm eat all food, this time we can harvest worm and casting. The result, after 6 months apply, each family has over 40 bins, every month they collect 30kg of worm to feed fish, chicken, duck, pig.. otherwise, the casting they got then can fertilize plant to give very

    Earthworm And Maggot Meals As A Potential Fish Meal Replacement

    Earthworm And Maggot Meals As A Potential Fish Meal Replacement Three meals were formulated from the earthworm (Endrilus eugineae) and maggot (Musca domestica) and fish (Engraulis encrosicolus). These meals were evaluated as a potential replacement for fishmeal. This is because fishmeal could be very expensive at times. The three meals were used in feeding the catfish (Heterobranchus isopterus) fry for 30 days. Read

    Worm composting in Vietnam

    Red wiggler worms (Eisenia species) can be used for composting kitchen scraps and organics. This species of worm “red worms” or “red wriggler” is hardy and reproduces quickly. One pound of worms consumes up to 1/2 pound of food scraps per day. Worm composting is an odor-free way to dispose of your kitchen waste. Another benefit of “vermicomposting” or worm composting is that it produces worm castings that are excellent plant fertilizer. Worm composting can be done indoors or outdoors. Where we are located near Vancouver BC, our climate is mild enough for outdoor worm composting most of the ye

    Earthworm,Cow,Grass – A big cycle!

    My sister in the cow permaculture world, uses earthworms as a handy source of protein for her cow.  I'm unlikely to follow in her footsteps since the infrastructure demands are quite high, but I wanted to share her process in case some of you are keen to give it a shot. She has a big ruber farm, in Cuchi of which she has sunk worm bins into the soil (surrounded by cinderblocks to keep the worms in place.)  He puts big sheets of plastic along the ruber line, on top she cover its to protest the ruber leaves and rain.  The bins are full of cow manure from her cow farm along wit
