How to raise crayfish, how to raise crayfish

The lobster feeding method is as follows:1. Breeding facilities. Breeding lobsters should build ponds with flat bottoms, good water storage and sufficient water sources, with an area of 4-10 acres, and the water depth should be kept in the range of 1 meter to meters, and during the breeding period, plastic film should be used to build protective nets along the edge of the pond to avoid lobsters escaping.

2. Preparation for stocking. One month before stocking lobsters, the water in the pond should be drained, the excess silt should be removed, and then the pond should be disinfected with bleaching powder, and then the rotten farmhouse fertilizer should be applied to it to cultivate plankton, and algae and aquatic plants should be planted at the bottom of the pond to provide a place for the lobsters to hide, rest and molt.

3. Feeding management. Lobster eating is more miscellaneous, in the process of breeding, you can be fed twice a day between July and October every year, mainly fish, snail meat, shrimp meat, watermelon, so that it can consume enough nutrients, and the rest of the season should be fed once a day, and it is best to feed at night, so that the amount of lobster food increases.

Crayfish farming: the site selection should be scientific and reasonable, the escape prevention facilities should be complete, reasonable stocking, water quality management, raising aquatic weeds, enemy invasion, molting management, reasonable bait, scientific management, and timely fishing.

1. The site selection should be scientific and reasonable: the selected pond is close to water resources, the water quality is refreshing and pollution-free, the inlet and drainage pipelines are convenient, the soil layer is suitable for clay, and the permeability can be good.

2. Anti-escape facilities should be complete: crayfish have the growth habit of tracing water hit-and-run, and fence net anti-escape equipment should be set up around the pond, and at the same time, the inlet and outlet must do a good job in anti-escape work, and check it from time to time.

3. Reasonable stocking: Shrimp free-range breeding is particularly important, and the success of stocking is equivalent to the success of all breeding. Lobster seedlings should be selected without disease and injury, complete appendages, bright fish body color, and consistent specifications and models, and 200 high-quality juvenile shrimp 50 Mingchang should be placed per mu.

If there is no self-propagating seedling, the basic principle of proximity principle acquisition should be used. In the transportation, it can not be extruded and dried, and it is promoted a little more than a few times to ensure the survival rate of lobster seedlings.

4. Water quality management: Crayfish has strong disease resistance, most of them have no pests and diseases, and only have high requirements for the clarity of water quality. As a result, 50 100 silver carp per 667 square metres can be used to control water quality.

During the feeding period, it is generally sprayed with 10 15kg of quicklime powder every 667 days every 667 to facilitate the molting of freshwater lobsters.

5. Raise aquatic weeds: "If you want to grow shrimp well, you must plant aquatic weeds", excellent natural ecological environment, rich and diverse aquatic weed network resources are the cornerstone of successful breeding. Aquatic plants are not only the concentrate feed of crayfish, but also the place where it inhabits and molts.

There are many types of aquatic plants, not only submerged plants, but also floating plants, and upright water plants, such as algae, eloso, black algae, lettuce, etc. The total area of aquatic weeds planted accounts for 60% and 70% of the area of the reservoir.

You'll be fine with the following precautions:

1- Environment: Say not too much, just go over the back, if the water depth can be placed stones for it to climb, in the water dissolved oxygen is insufficient and when sleeping at night, it can put half of the gills out of the water to breathe, while paying attention to escape, this guy can use pliers to open the circuit and clamp small objects such as wires to escape.

2-Food: C-k's belongs to the wide range of food, plant protein and animal protein in the wild will be ingested, artificially want to raise for a long time, can not only feed the same food, it is recommended to feed the best shrimp and small fish, the calcium can help the formation of new shells inside the shrimp and improve the survival rate of molting, plant protein as much as possible to feed clean vegetables, so as not pesticides to cause devastating damage to the nerve center of crayfish.

3- Molting: If you don't eat a few days before molting, don't touch it when you're ready to wait, and rest and recuperate; A few days after the molt is not moved, at that time it is the most fragile, in addition to the teeth are soft, the higher the temperature, the faster the hardening, at that time it is best not to scratch it, it is easy to cause the shell to deform, after the shell hardens, to increase the amount of Zen touch feeding, molting is equal to Nirvana, consuming a lot of its energy, maybe you don't know, every time the molt is a threshold of life and death for the lobster, there are many who die in the shell.

Tools Raw materials.

One fish tank. Method steps.

How to get lobsters: You can buy them at the aquarium or vegetable market, usually for one yuan, or you can catch them yourself.

Once you get a lobster, buy a fish tank or aquarium, preferably glass, so that you can clearly see the lobster's every move. Get a lid to prevent the lobster from jumping out of the tank. Spread a layer of sand and put some small pebbles to simulate the natural environment more realistically, so that the dragon staring dust shrimp can adapt to life in the fish tank.

Don't bask in the sun, lobsters are yin.

Crayfish are omnivorous, and can be eaten on both plant-based and macro-animal feeds. Plant-based feed. Plant-based feeds include plant straw, aquatic weeds, roots and leaves of aquatic plants, cohetic algae, silk algae, organic detritus, etc.

Animal feeds include aquatic insects and screws, mussels, fish, etc.

It is best to keep several lobsters together, so that the survival rate of lobsters is relatively high. Concealment.
