Can lobsters be polycultured with crabs, and can crabs and crayfish be kept together

That's what my neighbor is going to separate. He had been mixed before. I don't know how it's very little. After that they separated. There are significantly more layers than the previous one. (Note: The seedlings below are of the same weight).

No, crabs will eat lobsters.

Look at the news and say it's okay to scale. Self-perceived risk is higher.

Yes. Crayfish and crabs have very similar ecological habits, they are both crustaceans, and the required growth environment is also about the same. In addition, because the two have their own main growth period in the breeding mode.

Specifically, the main growth period of crayfish is from March to July every year, and from April to June to start to be marketed one after another, accompanied by a large number of **; The main growth period of crabs is from June to October, and the market time is generally in October. Therefore, crayfish can actually be polycultured with crabs.

Aquatic weeds are an important factor in the success of shrimp and crab farming. The species of aquatic weeds are mainly Elophylla, and if conditions permit, black algae and bitter grass can be planted appropriately (crayfish ponds can be cultivated aquatic weeds) to enrich the ecological environment of the breeding ponds.

River crabs and crayfish both belong to crustaceans, have similar eating habits, and also have the characteristics of cannibalism, so it is particularly important to plant aquatic plants in the breeding process.

Crayfish as the main species of stocking: 20,000 crayfish seedlings with a body length of about 3 cm per mu in autumn, 40,000 or slightly larger juvenile shrimp 40 kg 50 kg, 80 crab fingerlings with 160 kg per mu in winter, 50 silver carp fingerlings per mu in April and May.

Generally, the yield per mu is 80 kg of crayfish and 100 kg of river crab.

The stocking method of river crab as the main species: 400 crab seeds, 600 crab seeds, and 2,000 crayfish seedlings with a body length of about 3 cm per mu are put into 160 kilograms.

Generally, the yield per mu is 20 kg of river crab 30 kg, crayfish 30 kg and 40 kg.

Extended Materials. Lobster (scientific name: palinuridae) is a common name for a species in the family Lobsteridae of the Molluscausta phylum Arthropodae.

It is also known as prawns, dragon head shrimp, shrimp kui, sea shrimp, etc. It has a coarse cephalothorax, a hard shell, colorful colors, a short abdomen, a body length of generally between 20 and 40 centimeters, weighs about kilograms, and is partially chelae-free, and the abdominal limbs can evolve into chelae.

The heaviest can reach more than 5 kilograms, and is known as the lobster goby.

The body is thick cylindrical, dorsoventrally slightly flattened, cephalothorax developed, thick and spiny, with a pair of powerful supraocular spines on the anterior margin**, with a closed gill compartment.

It is mainly distributed in tropical waters and is a valuable seafood.

According to Chen Huangen, chief of the promotion section of Jiangsu Provincial Aquatic Technology Promotion Station, because crayfish will compete with river crabs for food, oxygen, and aquatic weeds, and both have the habit of self-harm and mutual harm, traditional breeding has always regarded crayfish as a predator in the crab pond, and there is a certain risk in raising crayfish in the crab pond. However, from the perspective of aquaculture practice, it is feasible to raise crayfish in crab ponds. The following problems should be solved in crab pond crayfish:
