(1) requirements for pond construction: the area of loach pond needs to be 5 mu to 10 mu, the water depth of the pond needs to be 1, 5 meters to 1, 8 meters, the pH value of sludge at the bottom of the pond is neutral, the wall of the pond should be compacted based on water leakage, the pond is convenient for water inlet and outlet, and the periphery of the farm is quiet, with good water quality and no pollution.
(2) Cleaning the pond: Before the loach seedlings is released in early spring, clean the pond with quicklime 20 days in advance, and then improve the water quality with oxygen-increasing particles and double salt. After cleaning the pond and adding water again, plant some water spinach, lotus root, water bamboo, water hyacinth and water peanut in the pond, which will help improve the water quality and avoid the exposure of loach.
(3) Fertilization water quality: Sprinkle some amino acid fertilizers in the pond 10 days before stocking to make the aquatic animals and plants that loach likes to eat reproduce faster.
2, stocking loach seedlings.
(1) loach seedlings's choice: Miaomai should buy loach seedlings with fast swimming, no damage and disease on the epidermis and a length of 3 cm -4 cm. When transporting seedlings, be careful not to hurt them. After transporting them to the pond, soak them with salt water before stocking.
(2) Stocking density: The best stocking time is mid-May. Each acre can be stocked with 10000 loach seedlings.
3. Feeding management.
(1) Feeding: After feeding the loach fry, six barrels specially filled with loach feed are placed beside the pond, and each barrel is 10 kg of puffed loach feed. After feeding for 3 days, the barrel was filled with 10 kg feed again to continue feeding. The feed diameter should be 0.3 mm at the beginning, 0.5 mm after 10 and 0.8 mm after 10 until it is one month old. After raising for one month, feed it with a special bait feeder. Feeding time should be between 7 am and 8 am. Each acre of pond should be equipped with 2 baiting machines.
(2) Water quality management: loach seedlings should change water frequently after stocking. Every time you change water, you must first drain a part of the pool water and then inject new water. Quicklime should be used to adjust the water quality every week, and the color of pool water is yellow and green.
(3) Disease prevention: biological agents such as yeast and EM bacteria are sprayed in the pond regularly to adjust the water quality, improve the immunity of loach and reduce the chance of loach getting sick.
(4) Fishing: It takes about 3 to 5 months from stocking loach to fishing. Misgurnus anguillicaudatus can be caught and marketed as long as it grows to 10 cm.
4. Problems that should be paid attention to in breeding.
(1) When purchasing loach seedlings, the quality should be strictly controlled to avoid unexpected situations after stocking. The transport will come. Loach seedlings should be disinfected before stocking.
(2) When raising loach, the breeding density cannot be increased in order to increase the yield, which may easily lead to loach diseases.
(3) Regular fertilization in ponds can cultivate all kinds of natural bait, which can reduce some money for buying feed.
(4) The price of Misgurnus anguillicaudatus is different in each period, so it is necessary to choose the right time for listing.
