How to raise seafood, the gold coins are through the seafood breeding method you can feed, so there are many breeding methods, but you have to learn a separate breeding method.

Sea crabs, how should they be raised, they can be raised in the sea.

If you add this, you can continue to bite, and if you want him, you can put him in living conditions.

At this time, the live sea crab is basically a blue crab; If it's winter, it might even be a pike crab. Feeding method: (1) Blue crab:

The correct way is to put the crab in the sink or basin at home (no water can be put in it), mix the salt water in a plastic bottle (old drink bottle) (close to the concentration of seawater, and poke a few holes in the bottle cap; Spray some on the crab every 3-5 hours (especially near the eyes and mouth). This can be raised for about 3-6 days. (2) Barracuda crab:

In contrast to raising blue crabs, salt water can be submerged in the eyes and mouth. For pike crabs, but the practice of our people who live by the sea is to buy them back and put the live crabs directly into the freezer of the refrigerator, so that they can be stored for at least more than 20 days.

You can raise it in a basin, it doesn't matter if the water is deep or shallow, it won't drown it. However, it is better to have water freshly soaked in the shell. You can let it bask in the sun, don't bask it for too long.

You can use tap water for water, but you don't need to use it until you dry it for a day. It is also necessary to adjust the water to salt water of concentration, because it is a sea crab, so it must be raised in salt water.

Crabs are omnivorous.

You can feed them fish, whether it's raw or dried. They may also be fed fish feed, bloodworms, dried shrimp, snails, mussels.

It is best to feed some grass-based foods frequently, such as bitter grass, eloso, etc.

As long as the feeding is OK, there is no need to worry about the rest, the sea crabs are very easy to raise.

It's not okay to raise it this way, unless you have a shrimp pond (saltwater pond) at home, and you can't raise it in a fish tank or bucket.

Believe me, my family is a crab farmer, and they can't be fed by fresh water, and they also eat shrimp feed and conch food.

The one can't be raised, and the wild one is even harder, because he's going to bask in the sun and move at high tide, and the sea is moving

1. Pond conditions for aquaculture: the pond area selected for breeding in the north is generally 10-20 acres of small and medium-sized ponds, and it is necessary to choose ponds near the sea area with sufficient water sources, no pollution, rich resources of small miscellaneous fish, shrimp and shellfish, and convenient intake and drainage. The depth of the pool should be more than 5 meters.

The bottom of the pool is better with sediment, and the bottom of the pool should be covered with sand about 15 cm.

2. Preparation before breeding:

2) Set up obstacles: In order to facilitate the rest and hiding of crab seedlings, when the pond is renovated, cement pipes, tiles, bamboo tubes and other obstacles should be placed at the bottom of the pond.

3) water and breeding bait organisms: half a month after the pond is cleared, you can open the smell of the water, in order to prevent some harmful organisms from entering the pool, you can use a 60 mesh sieve silk screen to filter seawater, the depth of the pool water is generally kept at about 80 cm, after the pond is flooded, fertilizer should be applied to cultivate bait organisms, - general n fertilizer in mu, p fertilizer is mu, and the transparency of the pool water should be kept at about 30 cm. The cleaning of the pond is main.

This includes the renovation of the pond and the cleaning of medicines. The renovation of the pond is carried out in late autumn after the crab harvest is carried out, and the pond water is drained and desilted and exposed to the sun. In the early stage of dredging, it is pumped with a mud pump, and in the later stage, it is leveled with a bulldozer, and a ring ditch is set aside along the perimeter of the pool, with a width of 2 4 m and a low beach surface of 30 40 cm.

Exposed to the sun for more than half a month, the bottom of the pond will be fully oxidized, and at the same time, the pond embankment, sluice, canal and other supporting facilities will be repaired.
