The techniques and measures for the artificial breeding of lobsters are summarized as follows:
1. Pond conditions Due to the strong vitality of lobsters, ponds, rice fields, and ponds behind the houses can be used for lobster culture. The depth of pool is 1-1.5 meters, and the bottom of the pool is slightly sloped. The pool week should be built anti-escape facilities, but also to install a good intake and drainage systems. In addition, the bottom of the pool can be equipped with bamboo or similar objects for lobster burrowing to prevent the lobster from “drilling†and “restingâ€.
2. Disposal of 10 to 15 kilograms of quick lime per acre pond prior to stocking the lobster. In order to ensure that the water quality is fresh and good, it is best to fill in 1/5-1/4 of the fresh water every day to keep its transparency between 20-25 cm. In addition, regular lime water is used to improve water quality and increase calcium quality. It will help lobster shelling and improve the survival rate.
3, transplanting grass lobster Xiyin afraid of light, the best pond in the planting of water peanuts, ryegrass and other forage, and on the water to grow appropriate amount of water hyacinth, water peanuts, water spinach, etc. (not more than 1/3 of the water), Planting Vallisneria, Goldfish, etc. on the bottom of the water is not only beneficial to lobster feeding, molting, breeding and other activities, but also reduces the mutual residual food.
4. The toxicity of the lime water in the pond after 7-10 days, such as the shrimp seedlings, disappears. After the water quality is normal, the seedlings can be planted. Due to the fact that there are no specialized seed production sites to solve the problem of seedlings, one is to directly put egg-holding shrimps and the other is to put juvenile shrimps. Its sources are directly captured in rivers, ditches, ponds, rice fields, and other water bodies, or acquired from the market. Generally, 40-60 kg of egg-bearing shrimp will be released per acre in May, or 80-120 kg of juvenile shrimp will be placed per acre in May.
5. Feeding lobster with bait is omnivorous, and both eat plant feed and eat animal feed. In order to reduce the cost of farming, feed should be based on vegetable feed, such as fresh water grass, water peanuts, bran, rice bran or semi-rotated barley, wheat, broad beans, rice and other crop stalks. Of course, some animal feeds (such as minced snails, small trash fish, and animal organs, etc.) can be put on conditional conditions, and lobsters will grow faster. The amount of feed is adjusted according to the water temperature condition: the water temperature is low, the feed rate should be low, about 6% of the body weight; the medium water temperature is higher, and the feed rate is higher, about 10% of the body weight. Feeding; later with the water temperature decreases, the bait rate also decreased, reaching about 3%.
6, fishing listing In order to obtain higher breeding efficiency, lobster fishing period should be based on market conditions and shrimp body specifications. It is usually started in June with shrimp or earthworm cages, with large-scale listings and small ponds, so it has been listed on the market until the end of October (if the shrimps are used in the year and harvested the following year, the net income in Muping can be achieved. More than 2200 yuan).
