What do clams feed clams? How do you raise clams?

Clams. Feeds on plankton such as diatoms, green algae, or rotifers. River clams.

Also known as the yellow clam, it is a freshwater shellfish with a medium-sized shell that is slightly triangular.

The chitin, slightly thicker and harder, the adult shell is about 40 mm long, the color of the shell surface varies greatly, often related to the habitat environment, it is brownish-yellow, yellow-green or black-brown, and the shell surface has rough ring ribs. River clams usually inhabit rivers, lakes, ditches or ponds, burrowing underwater and feeding on plankton such as diatoms, green algae or rotifers.

River clams, also known as yellow clams, is a kind of freshwater shellfish, its shell is medium in size, slightly triangular, the chitinous is slightly thicker and harder, the adult shell is about 40 mm long, the color of the shell surface changes greatly, often related to the habitat environment, brownish-yellow, yellow-green or black-brown, and the shell surface has rough ring ribs. River clams usually inhabit rivers, lakes, ditches or ponds, burrow to live underwater, and feed on plankton such as diatoms, green algae or rotifers, and can reproduce all year round, the fullest period of gonads is from May to August, and the best harvesting and utilization period is 1 instar and 2 instars. River clam has a high economic value, delicious meat and rich nutrition.

According to analysis, every 100 grams of clam meat contains 15 grams of protein, 3 grams of fat, and contains vitamins A, B1, B2, B12, C and iron, calcium, magnesium and other nutrients are also very rich. In addition, it also contains a certain amount of cobalt and taurine and other ingredients. In addition to stir-frying, frying, frying and boiling soup, clam meat can also be processed into dried clams, canned food and frozen clam meat and other products.

In addition to being used as a dish, river clam also has medicinal value and therapeutic effects. According to the "Compendium of Materia Medica", it is recorded"Clam meat can warm up and facilitate urination"。

In addition, according to modern medicine books, the clam meat has the effect of clearing heat and detoxifying. Moderate consumption of clam meat can be the first boils, swelling and poison, damp heat jaundice, inconvenience and other symptoms, and it also has a role in night blindness and promoting maternal milk secretion and speeding up the recovery of the mother's postpartum body.

The abundant vitamin B12 in clam meat has a special effect on anemia. The cobalt component contained in the river clam also has an auxiliary effect on maintaining the body's hematopoietic function and restoring liver function. Folk records often drink clam soup and eat clam meat to make people strong and strong.

Due to its nutritional, medicinal and therapeutic value, the river clam is not only loved by people in many parts of the country, but also widely welcomed in Japan, South Korea and some countries in Southeast Asia. At present, there are three main ways to develop and utilize river clams: First, organize fishermen and farmers to catch river clams in an appropriate amount in the rivers and waters with resources, which can be carried out all year round or in stages.

You can use a net or rake net with a mesh of about 2 cm to fish, if it is a single boat operation, you can catch a large and keep a small one. Second, in order to properly protect natural resources and increase production, rivers and lakes can be developed to increase artificial aquaculture. The method of increasing breeding is as follows:

Choose a water depth of about 2 meters, sand and mud bottom, flat terrain, a certain fertility, plankton rich waters stocking clam seedlings, stocking evenly scattered, density of about 15 kg per mu (specification centimeter 1 cm), 4 months after stocking 5 months can grow into commercial clams, can be stocked in the current year of harvest. The third is the use of pond aquaculture. The pond area is more than 2 acres, the water depth is more than 1 meter, the bottom is suitable for sandy soil, the predator organisms should be removed and exposed to the bottom of the pond for more than 15 days before stocking, and then 150 kg of farm fertilizer such as chicken manure is injected with water and 200 kg.

About 100 kg of clam seedlings are placed per mu. Clam ponds can also be mixed with grass, bream, silver carp, bighead carp and other fish (but can not be mixed with green and carp), pond clam farming after 5 months 6 months to reach the commercial specifications, a weight of more than one gram can be harvested on the market.

Liquor and wine are fine, but the main thing is that they cannot be drunk with beer.

Seafood is a high-protein, low-fat food that contains two components: purines and glycotides; Beer, on the other hand, contains vitamin B1, which is a catalyst for the catabolism of purines and glycotides. When purines, glycotides and vitamin B1 are mixed together, a chemical reaction will occur, resulting in a rapid increase in the level of uric acid in the human blood, destroying the original balance; Uric acid cannot be excreted from the body in time, so it precipitates in the form of sodium salt, forming stones or gout. When this kind of patient is severe, he is covered with red bumps, pain and itching, rolling on the ground, and unable to walk.

One of my relatives just eats seafood and drinks beer, and it takes a week for his leg to toss gout. I've tried it myself, and it's okay to have a little bit of it, but it's also related to personal physique, so it's better not to drink it for the sake of safety.

If you raise clams, you can feed them some small dried shrimp. It usually feeds on plankton such as diatoms, green algae, or rotifers.

Clams eat plankton, usually by placing bait in the clam pond that can promote the growth of plankton.

Clams belong to the category of shellfish, and they all eat algae, such as plankton such as kelp.

Let the tap water stand for 12 hours, add a little salt, add some sediment, and have floaters. It will eat.

Clams are edible, bait for fish and poultry, and can be used as fertilizer for farmland. What are the ways to raise clams? The following is the content of the clam breeding method compiled by Xuela, I hope you like it!

How to raise clams.

Clam meat is nutritious and easy to raise, so it can be used as a bait species for pond culture.

The river clam is fertilized in vitro, and the eggs develop into disc larvae, and after completing the planktonic life stage, they begin to grow shells and sink to the bottom of the pond, burying the shells in the silt at the bottom of the pond, and only extending the straw into the water to breathe and ingest the bait. Ponds where clams are kept should not be filled with pesticides and fertilizers, which are most likely to cause the death of clams. The water quality should not be overly fertile.

The bottom of the pool should be sandy. The water depth is maintained at about 1 meter. 60 130 kg of river clam seedlings can be stocked per mu.

River clams cannot reproduce continuously in the pond, so the stocking of seedlings in the second year can be appropriately reduced. The size of the clam seedlings is 800 4000 kg. If you buy clam seeds from other places, you can transport them in sacks or bales, and in order to reduce death on the way, you should maintain a certain humidity and do not stack them too thickly.

Before stocking, the pond water should be drained and exposed to the sun for 2 to 3 weeks before filling. When farming in ponds, soybean meal, wheat bran or rice bran should be fed, and chicken manure or other farm fertilizers can also be applied. The growth rate of the river clam is determined according to the feeding conditions, the average weight of the seedlings is about one and a half grams, and the weight can be increased by 4 times for one and a half months, Dak; up to grams in 3 months; up to grams at 4 months; 5 6 months up to 4 grams, 7 months up to grams, the weight is equivalent to 50 times the original seed, then it can be harvested.

When catching clams, an iron rake with a net can be used, and then the size is sieved with iron after catching, and the smaller individuals are still put back into the original pond to continue breeding.

River clams can also be polycultured with silver carp, bighead carp and grass carp, but not with herring and carp.

Crushed clams are good bait for yellow eels, and small clams can be fed directly.

1. What is a clam.

Clams are a relatively common seafood, which is widely distributed all over the world and in China. From the category, clams belong to mollusks as they are animals in the phylum Mollusca. As mollusks, clams also fit many characteristics of mollusks.

For example, mollusks are invertebrates, and clams are invertebrates, and they have no spine in their bodies. For example, the body of mollusks is generally relatively soft, but the outside of the body usually has a shell, and it is often symmetrical, and the body of a clam also meets this basic characteristic.

From the perspective of living environment, clams belong to seafood, which lives in the ocean, and are more abundant in the inner bay and at low and middle tides, and are also distributed in places with high salinity, but the number is slightly smaller.

2. Can clams be farmed?

As mentioned above, clams belong to a type of seafood. In fact, in addition to the edible value, the medicinal value and feed value of clams are also relatively high. They can also be farmed in captivity because of their relatively high economic value.

Because clams live in the ocean, they need to be particularly salinity when farming, and they cannot be cultivated with ordinary fresh water, but need to be mixed with a certain amount of salt in the water. After the salinity is regulated, the growth of clams will be better. When farming, clams can be fed plankton or seaweed.

1. The water quality should not be too fertile. The bottom of the pool should be sandy. The water depth is maintained at about 1 meter. Each acre of hostel can be stocked with clams.

seedlings 60 130 kg. Flower clams cannot reproduce continuously in the pond, so the stocking of seedlings in the second year can be appropriately reduced. The size of the flower clam seedlings is 800 4000 kg.

2. If you buy the clams from other places, you can put them into sacks or straw bales for transportation, in order to reduce the death on the way, you should maintain a certain humidity, and do not stack too thick. Before rearing, the pool water should be drained and exposed to the sun for 2 to 3 weeks before filling the water. When cultivating in ponds, soybean flour and wheat bran should be fed.

or rice bran, chicken manure or other farm fertilizers can also be applied.

3. The growth rate of clams is determined according to the feeding conditions, the average weight of the seedlings is about one gram, and the weight can be increased by 4 times in one and a half months. up to grams in 3 months; up to grams at 4 months; 5 6 months up to 4 grams, 7 months up to grams, the weight is equivalent to 50 times the original seed, then it can be harvested.

4. When catching clams, you can use an iron rake with a net, and then use iron to screen out the size after catching, and put the smaller individuals back into the original pool to continue feeding. Flower clams can also be polycultured with silver carp, bighead carp and grass carp, but not with herring.

Carp polyculture. Crushed clams are good bait for yellow eels, and small clams can be fed directly.

Hello dear, raising clams is to give clams the following food:1Seaweed:

Clams are a type of shellfish that need to consume plant foods such as seaweed for nutrients. 2.Plankton:

Clams can also obtain nutrients by ingesting plankton in seawater, such as phytoplankton, zooplankton, etc. 3.Organic Sediment:

Clams can also obtain nutrients by swallowing organic sediment from the seafloor, which is often rich in macros such as protein and nutrients such as carbon pamperwater compounds. It is important to note that clams should be kept in an environment similar to the environment in which they grow, such as beaches or areas with fierce estuaries. In addition, the feed of clams should be kept clean and hygienic to avoid contamination.

At the same time, it is also necessary to regularly replace the feed and clean the breeding box and other equipment to ensure the healthy growth of clams.
