Lobsters come out of the hole in search of food in a few months

It's probably the month. At the turn of spring and summer, when the water temperature rises above 10, the lobster will come out of the hole. Eating lobster is a season from May to October every year, during which the crayfish are relatively fat, and the best time is from June to August.

During the growth of lobsters, the flesh becomes plump in June, and three months is when lobsters grow their strongest. Lobsters like to inhabit hidden objects such as aquatic plants, tree branches, and stone crevices. The shrimp is nocturnal and does not like bright light.

Under normal conditions, they mostly hide in the deeper water or hidden objects during the day, and rarely move, but start to move after the sun goes down in the evening, and mostly gather at the shallow water to crawl and forage for food or mates. Extended Material 1Shrimp is rich in nutrients, and its meat is soft and easy to digest, which is an excellent food for people who are weak and need to recuperate after illness; 2.

Shrimp is rich in magnesium, magnesium has an important role in regulating heart activity, can protect the cardiovascular system, it can reduce blood cholesterol content, prevent arteriosclerosis, and at the same time can dilate coronary arteries, which is conducive to preventing hypertension and myocardial infarction; References: Lobster — Encyclopedia.

Crayfish begin to enter the hole from May to September.

Crayfish like to burrow during the breeding season. Crayfish can reproduce all year round, with the peak period from May to September.

After mating, the female shrimp will dig burrows into burrows one after another, and when the eggs mature, they complete the process of ovulation, fertilization and larval development in the burrows.

The cave is located about 20 cm above the surface of the pond and has a depth of 60 cm to 60 cm, with a small amount of stagnant water in it to maintain humidity, and the entrance is generally sealed with a mud cap to reduce water loss. On summer nights or after heavy rainstorms, it has a habit of climbing ashore and crossing dikes and entering other bodies of water. Therefore, the entire pond should be surrounded by bamboo chips, mesh, etc., with a 50-centimeter-high escape wall.

Lobsters like to dig holes, which has a certain destructive effect on the embankments of reservoirs and rivers, so it is not easy to breed lobsters in water bodies such as reservoirs and rivers.

May-June.

Crayfish enter the hole when breeding, and crayfish generally breed in spring and autumn. After the female shrimp is inseminated by mating, the breeding period begins. In the spring, crayfish enter the hole between May and June to hatch, at a water temperature of 20 to 25, and begin to hatch and emerge, and wait in the burrow for about 25 to 40 days.

After the seedlings emerge, the crayfish come out of the hole and move slowly. After coming out of the hole, the juvenile shrimp still live in the belly of the broodstock for a long time, and only when they grow to about 10 mm can they leave the mother when they can live independently.

After the insemination of crayfish in autumn, they begin to burrow, enter the burrow, and enter the breeding period. Usually crayfish enter the hole to spawn and hatch in mid-to-late September to early to mid-October, about 25 to 40 days, if the water temperature drops below 12, it will be out of the burrow when the water temperature is above 12 in the following spring. After the crayfish enter the hole, they will not go out of the hole until after spawning and hatching, and will not go out of the hole to forage and move halfway.

Precautions for crayfish farming.

Crayfish like to choose to burrow at night. During the day, crayfish are afraid of strong light and the threat of predators, and rarely burrow out of the water.

Crayfish burrowing prefers to choose soft loam soil. The soft soil is easier to dig, more suitable for crayfish to burrow, the soil is hard and the hole consumes too much physical strength, it is not easy to hit, it is deep, and there are deficiencies in moisturizing.

Crayfish like to burrow near the water's edge. The soil at the water's edge is moist, easy to make holes, and has good moisturizing conditions. Crayfish holes are concentrated 30cm below the water surface, and there are more holes on the water surface, less underwater, and the reason for less underwater is mainly related to ventilation.

The time when the crayfish come out of the hole depends on the local temperature. When the water temperature rises above 10 degrees, the crayfish in the cave gradually wake up, especially those that inhabit near the water line. You can also turn up the water level and force the crayfish out of the hole early.

When the water temperature rises above 10 degrees, the crayfish in the hole will gradually wake up and will come out of the hole.

Crayfish has a wide range of adaptability, has a wide range of suitable growth temperatures, and can grow and develop normally when the water temperature is 10-30. It can also withstand high temperatures and severe cold, can withstand high temperatures above 40, and can also survive the winter safely when the temperature is below -14. Crayfish grow rapidly, in the case of suitable temperature and sufficient bait, after more than 2 months of breeding, you can reach sexual maturity and reach the specifications of commercial shrimp, generally male shrimp grow faster than female shrimp, and the size of commercial shrimp is larger than that of female shrimp.

Like many crustaceans, crayfish grow with molting, which is often sought out for shelter, such as in aquatic weeds or under plant leaves. The maximum weight gain after molting can reach 95%, and sexual maturity can be reached after 11 times of molting, and sexually mature individuals can continue to molt and grow.

Its lifespan is not long, about 1 year. But in the case of food scarcity, lower temperatures and drought, the lifespan can be up to 2-3 years.
