Jinhua's local culture of lobster is feasible. In recent years, local farmers have been breeding, and they have succeeded and failed. The main reason for the failure was the lack of understanding of the lobster's habits, and lobster escape had lost most of its production. The lobster's characteristics and farming techniques are now described as follows:
First, the characteristics of lobster
1, lobster habits. The lobster is a kind of shell and shell animal. Similar to crabs, it has a pair of particularly developed chelators and has the habit of digging caves. It is usually drilled near the shore by water. The lobsters are afraid of light. When the light is weak or dark, they climb out of the cave. When the light is strong, they sink into the water or hide in the cave. The lobsters have two spawning seasons each spring and autumn. A pair of male and female lobsters can breed up to 480 shrimps at a time. Usually the lobsters listed in the early spring are the shrimps bred in the autumn of last year, and the spring broods only need to be cultured. It can be listed in many days. For the first year, the lobster farmers only need to keep the whole lobster for cultivation. In the fall, the lobster will cave in and go into the hole, and do not need to buy too many lobster seedlings in the second year.
2, appetite, food mixed. The lobster's appetite is very good, animal and plant feed can be, such as miscellaneous fish, miscellaneous meat, wheat, corn and Other wild food is its good feed.
3, afraid of dirty water, afraid of chemicals. Lobster is not afraid of dirty water, but it is very sensitive to chemicals such as pesticides, chemical fertilizers, and liquefied petroleum gas. As long as there are these chemicals in the pond, the lobster will be completely destroyed.
Second, lobster breeding technology
1. Create a good lobster growth environment. Lobster loves to make holes. Generally, the depth of the cave is 50 to 80cm. Some caves are more than 1m deep. In order to avoid escaping, the aquaculture water body should have a width of 1.5m or more, and a 0.5m high anti-escape should be installed around the quail. The net or inner wall has a smooth anti-escape wall and escape escape board. The fence also has to be buried 2m deep to prevent the lobster from escaping. At the same time, Hetang simulates the ecological environment of lobsters under natural conditions. The pools are planted with 10-15% of plants and concealed materials in shallow conditions to create a habitat for lobsters and shelling and reduce mutual killing. The impact of water quality on lobster production cannot be ignored. In the breeding process, the pH of the pool water is maintained between 7.5 and 8.5, and the transparency is 30-40 cm. It is necessary to constantly refill with fresh water, periodically splash lime solution, regulate water quality, and prevent disease from occurring. And shelling is not easy.
2, reasonable feeding feed. Lobsters will kill each other when they are starved and have insufficient food. Therefore, the amount of feed must be adequate. Lobster feed is animal and plant feed. Vegetable feed is wheat, aquatic grass, rapeseed cake, etc. Animal feedstuffs are miscellaneous fish, miscellaneous meats and livestock viscera. Normally, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters buzzing and the density of shrimp in the pond.
3, scientific fishing. Juvenile shrimps can grow to commercial specifications within 60 to 90 days when the temperature is appropriate and feed is sufficient. The seedlings were released in March, and the arrests began in June and sold large and small.
Lobster characteristics and farming techniques
Recently, a number of farmers in Jindong District and Lucheng District have been calling to ask whether Jinhua can breed lobster locally. How about aquaculture technology? The newspaper specially invited Jincheng Agricultural Technology expert Jin Chengbing to give an answer.
