Lobster farming methods: preparation of ponds, stocking shrimp fry, careful baiting, water quality management, disease prevention.

1, prepare the pond

Generally new lobster ponds can be used lime water with water to clear the pond, 100 kilograms per mu, if the use of old ponds or lakes to raise lobsters, dredging, trimming, exposure, stocking shrimp fry 10-15 days before, 50 kilograms of quicklime per acre with a dry pond disinfection. At the same time completely eliminate the pond catfish, loach, blackfish and snakes, rats and other predatory wild enemies.

2, stocking shrimp fry

Stocking shrimp fry should be carried out in the morning and evening on a sunny day to stock 2 centimeters of juvenile shrimp 6000-8000 tails or 3-5 centimeters of juvenile shrimp 4000-6000 tails per mu. The same pond stocked shrimp fry specifications require neat and consistent. At the same time can be stocked in the pond water about 50 grams of flowers, silver carp 300-400, 200 bream.

3, careful baiting

3 days after the release of seedlings, cast to stranded small fish and minced meat, 3 days after 1 month to put small fish, minced meat or with feed, to be shrimp fry grow to 6-7 cm, can be fed all the rolled snail, mussels and the appropriate amount of plant-based feeds, such as wheat, bran, maize, biscuit meal, or with feed. Daily feeding to eat, eat, do not leave residual bait shall prevail, generally in the middle, crayfish according to 15%-20% of body weight feeding, adult shrimp according to 5%-10% of body weight feeding, specifically according to the shrimp's eating situation can be adjusted.

Feeding 2 times a day, once in the morning and evening, evening feeding accounted for 70% -80% of the daily feeding, the bait should be cast around the pond, and properly dispersed, lobsters concentrated in the appropriate place to cast more, in order to facilitate their feeding.

4, water quality management

Lobster fast-growing, vigorous metabolism, oxygen consumption, so the shrimp pond water quality should be kept fresh, add water 15-20 cm deep every week, to ensure that the water quality is fresh, clean and cool, and there is enough dissolved oxygen, water transparency control in the pond more than 35 centimeters deep, when the weather is too hot, it is necessary to deepen the pond to stabilize the pool water temperature. Strictly prevent the water quality by industrial pollution, pesticide pollution and chemical pollution.

5, disease prevention

Should be diligent inspection, diligent inspection of ponds, pay attention to lobster feeding, activity, growth and moulting, in order to take the necessary technical measures in a timely manner. Timely removal of moss in the pool; often check the inlet and outlet filters to prevent the filter breakage and make the lobster escape or wild fish and other harmful organisms into. Often pay attention to the pool whether there are hostile organisms, such as water rats, water snakes, waterfowl, etc., if any should be removed in a timely manner.
