1. There are many types of feed for farming razor clams. Which feed is the most nutritious for farming razor clams?

Special feed is also good. It is also good to choose one or two brands that are relatively large. ...In addition to special feed, chicken feed can also be fed. The state strictly controls chicken feed, so it should be more reassuring. If the bird food we sell uses special feed, search for Nongxin Food Pets on Taobao for various mynah rations for everyone to choose from. The food ingredients of razor clams are mainly small living things and suspended fine particles in the roller bucket. Planktonic larvae feed on tiny single-cell algae. In recent years, yeast powder and some plant starch have also been used as bait for planktonic larvae.

The feeding and fertilization of razor clams. The feeding method of razor clams is filter feeding, and the main feeding method is bivalves, which account for 91.5% of the bait. In addition to floating algae, razor clams also feed on organic debris and particles. In winter or early spring, the water temperature is low, the light is not strong, and it is difficult to grow algae with fertilized water. You can use 5 to 10 kg/mu of soybeans, add 4 to 6 times the seawater, grind into soy milk, and sprinkle it all over the pond. It can be directly fed by razor clams and can also be used as fertilizer to cultivate algae.

Fertilization and algae cultivation are important links in the cultivation of razor clams. Fertilizers can be inorganic fertilizers and organic fertilizers. Inorganic fertilizers are generally used for irrigation, while organic fertilizers can be used for irrigation or as base fertilizers. During the entire cultivation process, do not always use chemical fertilizers, otherwise excessive use of chemical fertilizers will destroy the self-purification ability of the matrix of the angelica pond; chemical fertilizers have a single nutrient, the algae phase formed is unstable, and the fertilizer effect is not long-lasting. Fertilizers can be ammonium bicarbonate, urea, superphosphate, etc. Organic fertilizers are mostly organic carbon fertilizers, such as Angel Botian yeast-sourced organic fish fertilizers.

Thank you everyone.

The most nutritious feed for razor clams are plankton, seaweed, diatoms, chicken manure, compound fertilizer, and urea.

You can choose mayfly larvae, or you can choose chemical fertilizers or fresh fish, and you can mix it with chicken manure. The nutritional value of the feed you choose must be particularly sufficient, and it must contain ammonium bicarbonate and compound fertilizers.

Ascaris, chicken manure, duck manure, urea, or you can also feed some plankton, you can also choose to feed some small insects, which are the most nutritious.

The most nutritious is diatom, followed by green algae. These things can grow very well, and this kind of feed is also relatively common.

No feed is needed. Razor clam larvae are filter-feeding tidal flat organisms that feed on algae in sand and seawater. Their diet includes plankton such as diatoms, green algae or rotifers. Razor clam seedlings will grow autonomously as long as the environment is suitable, and no additional feed is needed.

Mainly fertilizers, chicken manure, cow dung, urea, etc. These feeds are very nutritious for clams.

At this time, you can use some compound fertilizer, urea or chicken manure, and you can also add some fresh fish, or directly feed the fish with mixed feed.

They prefer to feed some plankton, or some seaweed in the water, which can be used as food.

3. What is the best way to fertilize the water when breeding clams?

Razor clam farming takes 6-7 months or 15-16 months from the start of stocking to the end of catching. Early sowing is recommended in the appropriate sowing season, and generally ends before the Qingming Festival. Seeding should be carried out during the high tide. For external cultivation, 70 kg of 1 cm long clam seedlings can be sown per mu, and 60-80 kg per mu in the inner pond. Do not overcrowd. Before sowing, if it rains and there is a lot of fresh water, 10 kg of coarse salt can be sprinkled per mu to facilitate the drilling of razor clam seedlings. About a week before sowing, add 20 cm to 30 cm of new water through a 60-80 mesh silk screen, apply 50 kg of chicken manure per mu, and basic bait organisms in the breeding pond.

4. What fertilizer is best for razor clam farming?

Sinonovacula constricta, like other bivalves, are filter feeders. In the planktonic larval stage, the cilia on the face plate agitate the water flow and filter food; after attachment, the juveniles and adults rely on the cilia on the gills to move the water flow, and the cilia on the gills and labia to filter food (see Figure 3 for feeding status). Filter feeding is a passive feeding habit. It cannot actively hunt and select food, so the food composition is often affected by the sea area, season, etc. In general, the choice of food by filter feeders is mainly to meet the requirements of swallowing, that is, the selection of food particle size is relatively strict, and the selection of food nutritional content is not obvious.

The food of Sinonovacula constricta mainly consists of microorganisms and suspended microparticles. The food of planktonic larvae is microscopic single-cell algae, such as Phaeodoctylum tricornutum, Dicrateria inornota, Isochrysis galbana, Chaetoceros mueller, Chaetoceros simplex, Chaetoceros calcitrans, Nannochlorisoculata, Dunaliella sp., and Piatymons sp. In recent years, yeast powder and certain plant starches have been used as bait for planktonic larvae in artificial breeding, which has also achieved certain results.

Inorganic fertilizers are mainly used for pond culture of razor clams. Green manure and organic farmyard manure such as human and animal feces and urine can easily damage water quality and bottom quality after application, so they are rarely used. Superphosphate and sodium bicarbonate have the advantages of good fertilizer efficiency, convenience, economy and safety in use, and are the main organic fertilizers used for pond culture of razor clams.

Razor clam, scientific name Sinonovacula constricta, also known as "little fairy", belongs to mollusk, bivalve, order Clams, lives in the ocean, and is a common seafood ingredient. The shell is brittle and thin, long and flat, with an oblique groove from the top of the shell to the belly edge, hence the name Sinonovacula constricta. Ningbo has many tidal flats along the coast, which is a unique advantage for breeding razor clams. It is a popular seafood specialty in Ningbo. The area around Ninghai Changjie faces Sanmen Bay, with a large amount of fresh water injected all year round. The seawater is of appropriate saltiness, the bait is rich, and the soil is mainly mud and sand. Therefore, razor clams grow fast, are large, tender and fat, white in color and delicious, hence the name Changjie razor clams.

Still rely on chemical fertilizers, chicken manure and fresh fish.
