In recent years, the lobster market has been booming and the momentum has been increasing. Lobster has become a new bright spot for rural farmers to increase their income. The three characteristics and feeding methods of lobster are introduced as follows:
First, low investment, effective fast lobster spawns 2 times a year, once in autumn and once in spring. A pair of male and female lobsters can breed up to 480 shrimp seedlings at a time. Usually, the lobsters listed in the early spring are the shrimps bred in the autumn of last year, and the spring bred larvae only need to be cultured for more than 50 days and can be put on the market. For the first year, lobster breeders only need to keep large whole-body lobsters for breeding. In the fall, lobsters will cave into the hole to breed and they will not need to buy too many lobster sprouts in the second year. Because lobsters love to burrow, the cocoons in low-lying highs and inner tangs should be at least 5 meters wide, and the fence should be buried 2 meters deep to prevent lobsters from escaping.
Second, the appetite is large, food-like hybrid lobster likes to live in the waters with peanuts, rushes of grass, lobster ponds can simulate the ecological environment of the lake, plant some white peony, water peanuts, a shade in the summer to prevent lobster precocity, the second Can breed lobster-eating plankton. Lobster's appetite is very good, wheat, corn and other wild food are its good feed. Lobsters are crustaceans that grow once each time the shell is removed. Therefore, the pond should be frequently filled with fresh water to help the lobster grow.
Third, not afraid of dirty water, afraid of chemical lobster afraid of dirty water, but it is very sensitive to pesticides, chemical fertilizers, liquefied petroleum gas and other chemicals, as long as there are these chemicals in the pond, lobster will be completely destroyed. The following “character†can be adopted to increase the production and efficiency of lobster aquaculture.
1. Three days after feeding the lobster, it is necessary to cast one month or so of small fish, minced meat and compound feed. When the shrimps grow to 6 cm to 7 cm in length, they can be fed with chopped snails, coriander and appropriate amount of vegetable feed. They are fed twice a day, once in the morning and evening. The bait should be placed around the pond and properly dispersed; the amount of bait per day is: the shrimp is generally fed at 15% to 20% of its body weight, and the prawns are given at 5% to 10% of its body weight. Specific can be combined with the shrimp's diet to increase or decrease as appropriate, generally shrimp to eat, eat, no residual bait prevail.
2. Changing the water The lobster grows fast and consumes large amounts of oxygen. Therefore, the water quality of the shrimp pool should be kept fresh. Add 15cm to 20cm of water each week to make the water fresh and clean, and have enough dissolved oxygen. The transparency of the pool water should be controlled at 35cm. Above, when the weather is too cold or too hot, pool water should be properly deepened to stabilize the water temperature and prevent extreme temperatures.
3, oxygen increase When the water is low in dissolved oxygen, water quality is aging or thunderstorms, sultry, continuous rainy weather, should reduce the amount of bait or bait, and pay attention to observation. If the lobster is found to be unresponsive, the shore is set up and the floating head is crawling on the shore. This indicates that the lack of oxygen is serious and should be promptly filled with water or aerator to increase oxygen.
4. Qin Qin should be diligently inspected and diligently survey the ponds, pay attention to the lobster's foraging, activities, growth, and shelling, and take timely measures. It is necessary to continuously remove the moss in the pool, check the strainers in the inlet and outlet, and pay attention to the prevention and control of shrimp disease. Pay attention to whether there are any predator organisms in the pool, such as water mice, water snakes, water birds, and harmful fish. If any, kill the fish in time. And drive away. In addition, duckweed, algae, water grass and other harmful organisms should be removed at any time.
