In recent years, China's demand for crayfish has been increasing, crayfish is an omnivore, it grows fast, adaptability is relatively strong, want to raise more and more farmers.

So want to raise a good crayfish, what are the farming tips?

1, lobster seedling

Now freshwater lobster is generally known as a unified crayfish, basically no special varieties.

This is no mutation or there are other varieties.

Here we are talking about the seedling is actually some good and some poor this distinction, in the selection of seedlings carefully selected and refined cultivation, although it is after the screening of shrimp seedlings and artificial pairing of shrimp but they are a variety of this still do not need to produce doubt, the quality is still very good.

2, on the water quality

Outside the legend is more widespread will think lobster is in the stinking ditch inside the growth out, in fact, this is a very wrong idea.

While lobsters can survive in dirty water, but it just means that he can survive when the water inside, will not die.

Lobster also needs to be inside the fresh high water quality in order to culture the high yield, the general requirements of the pool water in the water plants need to cover 30% to 60%.

The transparency of the water should be maintained at about 30 centimeters, and the oxygen content should be greater than 5 milligrams per milliliter.

It should be noted that the water must be changed regularly, and 1/3 of the water should be changed each time.

If the weather is hot, the water level must be kept above 80 centimeters.

3, on the feed

Lobster is not a picky species, decide whether the lobster grows well, it is important to give the lobster to supplement the protein intake.

So you want to raise a relatively large size lobster, you have to feed the lobster to eat animal feed.

You can go to the market to buy some small fish or snails to feed the lobster, in conjunction with plant-based good water plants, so that the lobster grows very large.

While the lobster can eat some rotten things, but rotten and spoiled food do not feed it to eat, this will also make the water quality of the pool worse.

Giving the lobster some dead minnows will still work.

4, catch the big stay small, reduce density

Start feeding half a month later, in order to reduce the density of crayfish should be up to the specifications of the market crayfish (shrimp do not catch holding eggs) fishing sale.

Suggestion: use a slightly larger mesh cage fishing, otherwise the mesh is too small, will trap the young shrimp in the cage and affect its normal feeding growth.

5, transplanting water plants

Crayfish for the early spring newborn shoots of water plants are very happy to eat, therefore, to strengthen the feeding of feed to reduce the crayfish on the young shoots of water plants to ensure that the water plant sprouting growth.

For some ponds with less water plants, in mid- to late April can be transplanted in the pool of bitter grass, water hyacinth, aquatic plants such as aquatic peanuts, aquatic peanuts transplanted along the edge of the stick put.

The same pond to transplant a number of different varieties of aquatic grass, and crayfish aquaculture pond aquatic grass covers an area of about 1/3 of the pond is appropriate to ensure that throughout the breeding period is not out of grass, divided into poolside, shallow and deep water areas in different places for transplantation in order to meet the lobster feeding, climbing, shelling to avoid the needs of many aspects.

The above is the crayfish farming tips, want to raise good crayfish, we must check the crayfish feeding, activity, every day should be day morning and evening each pond patrol, pond whether there is leakage or have a hole to escape shrimp and other phenomena, found that the problem is immediately dealt with.
