You can harvest the large ones for fish bait and return the small ones and the egg cases to a freshly prepared bin with new bedding. Use the old composted garbage and bedding as a nutrient-rich soil amendment around plants or in your garden.
Worms move by the powerful stretching and pulling strength of their muscles. They detect light from dark and are very sensitive to vibrations in the soil.
Each worm bears the reproductive system of both sexes, but two worms must mate for reproduction to take place. Redworms consume large amounts of organic matter and are found in manure and compost piles and decaying leaves. They live closer to the surface than earthworms and reproduce very quickly in captivity. Eight redworms become 1, redworms in six months!
Commercial Earthworm Production Introduction Many Texans are interested in raising earthworms as a hobby, for their own use, or as a source of income. Much interest in vemiculture worm raising has been kindled by extravagant claims of enormous potential markets for earthworms in agriculture, in large scale waste disposal systems, and as a source of food for animals and even people.
The major use of earthworm today is as bait for freshwater sport fishing. Some worms are also sold to home and organic gardening enthusiasts for soil improvement and composting of organic refuse.
Although research and development activities relating to other uses for worms are underway in various places, the opening of new markets for worms and castings will be slow and somewhat uncertain. Thus, anyone interested in the earthworm business should explore the potential local markets carefully, particularly if a full-time occupation is contemplated.
Some earthworm wholesalers sell breeder stock to new growers and promise to buy the worms back from the grower at a "going wholesale price. Such an arrangement could help a new grower market his produce, but his success would depend almost entirely on the wholesaler's honesty and ability to meet his obligations to the grower.
Prospective growers considering such an arrangement should check carefully with their local Better Business Bureau and Chamber of Commerce, and also with the wholesaler's other growers or customers, to determine his reputation before entering into a contract. Establishing an earthworm-business should not be done on a trial and error basis. Earthworms are a form of livestock and there are certain minimum requirements of care that must be met on a regular schedule.
New earthworm growers should consider entering the business on a small scale and learn to raise worms successfully before attempting mass production. Taxonomy Earthworms are scientifically classified as animals belonging to the order Oligochaeta, phylum Annelida. In this phylum there are about 1, species of earthworms grouped into five families and distributed all over the world.
The most common worms in North America, Europe, and Western Asia belong to the family Lumbricidae which has about species. Earthworms range from a few millimeters long to over 3 feet, but most common species are a few inches in length. Only a few types are of interest to the commercial earthworm grower, and of these only two are raised on a large-scale commercial basis.
Some of the more common species used for bait are: Nightcrawlers. This earthworm is common in the northern states and may be picked from fields and lawns at night for commercial fish-bait sale.
Although very popular with fishermen, they are not commonly raised on a commercial basis because they reproduce slowly and require special production and control procedures. Field worms also known as garden worms. These make excellent fish bait and are often preferred by those who want a small number of worms for their own use. They are not prolific breeders and are not recommended for commercial purposes.
Manure worms red wigglers. These are particularly adaptable to commercial production and are commonly grown by successful worm farmers. Red worms. These are basically another type of manure worm, differing mainly in size and color from their larger and darker cousins. They are adaptable to commercial productions and together with manure worms constitute about 80 to 90 percent of commercially produced worms.
Manure worms and red worms can adapt to living in many different environments. They will eat almost any organic matter as well as many other types of materials which contain organic substances that can be ingested. Worms are present it manure piles or in soils containing large quantities of organic matter, but the new grower should purchase breeding stock from a reputable grower or distributor.
Biology Because the physical structure of earthworms varies only slightly from one species to another, a description of one species will apply in most respects to any other. Lumbricus terrestris , is used for descriptive purposes. The earthworm, while primitive, has well-developed nervous, circulatory, digestive, excretory, muscular, and reproductive systems.
The most noticeable external feature is the ringing or segmentation of the body, which involves nearly all of the internal structure. The nighcrawler has about segments, while manure and red worms have approximately Segmentation within the earthworm serves the same general function as the division of the animal body into organs --that is, different segments perform different functions.
The first section of the earthworm consists of the mouth and the prostomium, a lobe which serves as a covering for the mouth and as a wedge to force open cracks in the soil into which the earthworm may crawl. Small hair-like structures, called setae, are located on each segment. These can be extended or retracted for movement.
The worm's lack of protruding structures other than setae facilitates efficient burrowing; in addition, various skin glands secrete a lubricating mucus which aids movement through the earth and helps to stabilize burrows and casts. The earthworm's digestive tract is adapted to its burrowing and feeding activities. The worm swallows soil or residues and plant litter on the soil surface.
Strong muscles mix the swallowed material and pass it through the digestive tract as digestive fluids containing enzymes are secreted and mixed with the materials.
The digestive fluids release amino acids, sugars, and other smaller organic molecules from the organic residues. The simpler molecules are absorbed through intestinal membranes and are utilized for energy and cell synthesis. Earthworms lack specialized breathing devices.
Respiratory exchange occurs through the body surface. Earthworms are usually not self-mating although each individual possesses both male and female reproductive organs. A mutual exchange of sperm occurs between two worms during mating. Mature sperm and egg cells and nutritive fluid are deposited in cocoons produced by the clitellum, a conspicuous, girdle-like structure near the anterior end of the body. The eggs are fertilized by the sperm cells within the cocoon, which then slips off the worm and is deposited in or on the soil.
The eggs hatch in about 3 weeks with each cocoon producing from ten to twenty worms with an average of four. Earthworms and soil productivity. Numerous investigators have pointed out the beneficial effects of earthworms. Some of these are as follows: They aid in the degradation of organic residues in the soil with the release of elements such as carbon, nitrogen, sulfur, and other nutrients.
The action of the digestive fluids and increased microbial activity in the casts droppings tends to solubilize inorganic plant nutrient elements present in inorganic soil minerals. The structural stability of ingested soil is improved through increased microbial activity while the soil is within the work and after it has been deposited as casts.
The extensive burrowing of the earthworm improves soil aeration and may increase water penetration into soils. Under natural conditions the earthworm will feed on surface organic litter and deposit its casts in the plant root zone. After further microbial decomposition of the partially digested residues, plant nutrient elements are released. Although earthworms are considered beneficial to soil productivity or plant growth, few valid studies have been made to determine whether their presence will significantly improve plant growth.
This should be a plastic or rubber bin with no holes at the bottom. Set it up next to your worm habitat. Turn a bright light on, and gently scoop the soil into the bin with a hand scooper. With the light on, your worms will start to burrow into the deeper layers of the soil. If your collection is really large, you can use a shovel instead of a scooper. Remove layers from your new bin in minute increments. Leave the light on and set your new bin under it for 10 minutes to give the worms time to burrow deeper into the soil.
After 10 minutes, use your scooper to remove the top 2—3 inches 5. Then, wait another 10 minutes and repeat this process. Continue doing this until almost all of the soil is removed. Discard the excess soil or use it in your yard as fertilizer.
It takes the worms quite a bit to move down a few layers, so take your time in between scoops. Be gentler the deeper you go. Add the worms you removed to their new habitat. Place some food scraps or manure in the new habitat. Then, carefully pour the worms that you removed into their new home. The worms will feed and get to work building a new bedding layer.
Move the soil in the old habitat to one side. Put on a pair of gloves. In the bin where you originally held your worms, push the soil to one side of the container. Pile the soil up as best that you can to keep the worms on one side. Pour fresh soil into the empty side and add some food. With roughly half of the bin empty, grab a fresh bag of soil. The food will encourage the worms to stay on that side of the habitat. This will ensure that the worms make the fresher side their home.
Replace the old soil after weeks. Use your scooper to gently remove the side with the old soil in it. Pour fresh soil into the half that you emptied to replenish the habitat. Include your email address to get a message when this question is answered. If you notice a lot of worms dying when you first put them in the habitat, the soil is no good. Replace it with an organic soil that is free of additives. Helpful 0 Not Helpful 0.
