What is bait feeding in Jintan mode?

The bait feeding for the jar mode is as follows:

First, after fertilization and water cultivation, benthic organisms such as earthworms, rotifers, cladoperates and planktonic algae in the water body provide natural active bait for river crabs; At the same time, according to the proportion of 5% of the storage of river crabs, pellet feed is fed to ensure that the bait of river crabs is sufficient.

Second, according to the nutritional needs of river crabs at different growth stages, in accordance with the principle of "fine before and after, green in the middle", the feeding ratio of animal bait and pellet feed should be reasonably adjusted. Before May, crab species were concentrated in the temporary breeding area to intensify cultivation, and the daily feeding of fresh small trash fish, clam meat and other animal bait, chopped and fed 1 kg per mu, with an appropriate amount of pellet feed, the ratio was 4:1; From May to September, river crabs were susceptible to high temperatures, and the feeding ratio of small trash fish and pellet feed was adjusted to 7:

3;In October, the river crab entered the fattening stage, and the feeding ratio of small trash fish to pellet feed was 12:1.

Third, in view of the characteristics of small shrimp and small fish, a small amount of mystic shrimp should be put into the breeding pond for the snakehead to eat.

Bait feeding. Freshwater lobsters are omnivorous and like to eat fresh trash fish and snail mussels. In order to facilitate shallow irrigation, drying of paddy fields, application of chemical fertilizers, pesticides or fishing, shrimp ditches and shrimp ponds must be excavated in shrimp paddy fields.

Shrimp ditches can be excavated after transplanting, and the method of opening should depend on the shape of the field, the size of the area and the direction of the outlet. If the rice field is small, it can be opened into the shape of "field"; If it is a long and large field, it can be opened into an inner "well" or an inner "field" shape, and the width and depth of the ditch are suitable for meters. The shrimp pond can be opened at the intersection of the shrimp ditch or the four corners of the field, and the shrimp ditch communicates.

Shrimp ponds are generally square and deep. Animal bait such as earthworms and livestock and poultry offal, and like to eat soybeans, soybean cakes, bran, corn and fresh aquatic plants and other plant bait, and can also be fed shrimp with compound feed, which shows that the bait problem of freshwater lobster is easy to solve. According to general experience, the amount of bait should be mastered to eat, eat, and leave no residual bait, generally small shrimp according to 20 25% of body weight, medium shrimp according to 15 20% of body weight, prawns according to 10 15% of body weight bait, feed twice a day, once in the morning and once in the evening.

Because freshwater lobsters feed mainly at night, they are fed 70 to 80% of the day's bait at night, and the bait is cast in the shallow water by the pool. Bait to do timing, fixed, quantitative, qualitative, each pond can be set up 2 4 bait observation table, every morning to observe whether the bait is eaten, to determine the amount of bait at that time, the amount of bait is too small will inhibit the growth of lobsters or kill each other due to hunger, too much will increase the cost and cause the deterioration of the pond environment, the growth and shelling of lobsters is not good. The bait can be used as a general shrimp bait or a lobster-specific bait.

There are three feeding techniques:

1. Feed according to feeding habits. First of all, according to the above description of the eating habits of crayfish, it can be fed twice a day, respectively at 7-9 o'clock in the morning and 5-8 o'clock in the evening. Secondly, each feeding should be slow and slow feeding, carefully observed, according to the feeding situation, not after sprinkling and leaving.

Finally, do fixed, timed, and quantitative to ensure that there is no need for spoiled bait.

2. Feed according to temperature and water quality. Crayfish eat vigorously when the water quality is good and the temperature is suitable, so they can be fed more at this time. On the contrary, when the temperature is too low or too high (generally more than 35), rainy days, water, agricultural land, commercial and residential land, industrial geology, etc., it is necessary to feed less, and do not feed when the situation is particularly bad.

3. Feed according to the stage of growth and development. First, at the stage of juvenile shrimp, rotifers, clades, and flexopods are cultivated for their predation, and a small amount of feed is sprinkled in the later stage of the seedlings.

The eating characteristics of crayfish should be understood first. First of all, crayfish have a miscellaneous diet, which can eat both plant feed and animal bait, such as aquatic insects, etc., and of course they will eat feed, and they will eat the same kind when they are not fed enough. Secondly, the crayfish has a short stomach and small intestine, and in order to maintain the body's essential nutrients and energy, it must eat constantly, but the peak feeding period is 7-9 o'clock in the morning and 5-8 o'clock in the evening.

Finally, crayfish, like many fish, tend to eat more with higher temperatures, but too much can also reduce their food intake. The second is feed selection. According to the eating habits of crayfish, you can choose soybean meal, wheat bran, vegetable leaves, corn, trash fish, snails, earthworms, animals, etc., or directly choose special artificial compound feed, with plant feed.
