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

    Red Wigglers – King of Compost Worm

    Red Wigglers (Eisenia Fetida), the king of composting worms, are the most popular and versatile of the composting worms. They need 3 things to thrive on breaking down your organic material: Air, Water and Temperature. Provided a good environment, they can eat 50 to 100% of their weight in food a day and produce three cocoons a week. Each cocoon can produce 1 to 5 baby worms. Red Wigglers (Eisenia Fetida) are called a lot of names Redworms, Tiger Worms, Manure Worms and Compost Worms. These worms are the most common composting worm on the market. They also are the smallest compost worm on the

    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

    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 are being bred as an alternative feed source, and the waste is being seen as a rich fertilzer. A win-win some would say. 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 agronomic practice to improve on productivity. Those engaged in dairy,

    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

    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

    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

    Prawn Productivity Improved When Grown With Worms

    by Alice Mitchell10 April 2015, at 1:00am AUSTRALIA - Growing prawns and worms in the same integrated system can lead to improved productivity and waste management, recent results from a Queensland Department of Agriculture and Fisheries research project show. The two-year study is testing the concept of fully recirculating pond water from intensive prawn culture ponds through polychaete-assisted sand filters (PASF), to create sustainable supplies of prawns and marine worms.
