How to breed loach fish in lotus seed ponds, and can ponds breed loaches

Pond loach, generally choose cement pond or triple soil pond, pond depth 70 100 cm, water depth 50 60 cm, the bottom of the pond spread 15-20 cm thick fat mud, the area of the pond can be large or small, with 2 3 acres as good. The pond should be easy to drain and irrigate, and the inlets and outlets should be fenced with barbed wire. The pond should be cleaned and disinfected before stocking, and the method and dosage should be the same as that of the fry pond.

If there is no quicklime, it can also be disinfected with bleaching powder, with a dosage of 4-5 kg per mu. If conditions permit, fish collection pits can be set up near the pond** and drainage outlets to facilitate future fishing. Before loach seedlings enter the pond, fertilizer should also be applied to promote the proliferation of plankton in the water.

After fertilizing 2 5 days, the loach seeds can be put into the pond. 30-50 kg per mu can be stocked, and the stocking amount can be increased if there are abundant water conditions. According to the water quality of the pond, some organic and inorganic fertilizers should be applied frequently to cultivate the water quality.

In addition, a certain amount of artificial bait is also fed every day. The types of bait fed include fish meal, pig blood meal, silkworm chrysalis powder, rice bran, wheat bran, vegetable cakes, etc. The amount of feed can vary depending on the season.

5 June is 4 to 5 of the loach weight; From July to August, it is 8-10; From September to October, it is 5 to 6. A bait table should be set up in the pond, and the bait should be put on the food table, and each pond can be set up with 3-4 bait tables according to the size. Check the feeding situation before baitting, and reduce the amount of food if it is found that it is not finished.

Generally, it is necessary to eat 2-4 hours after bait, and clean the bait table every 3 to 5 days to prevent diseases. Ponds should be filled with fresh water frequently to maintain a good water quality environment. The pool water should be neutral or weakly acidic (pH value is 6 5 7 2), and disinfected with 1 2ppm of bleaching powder at certain intervals (15 30 days) to achieve the purpose of sterilization and disease prevention.

You can learn loach farming techniques from the China Organic Agriculture Network.

1. Pond environmental treatment.

One week before the pond is filled with water, 50 100 times of Yifuyuan aquatic EM bacterial liquid dilution is used instead of lime and bleaching powder to evenly spray to disinfect and purify the pond. Special aquatic products (such as shrimp, soft-shelled turtle, loach, eel, mandarin fish, etc.) should be evenly sprayed with 10 times of Yifuyuan aquatic EM bacterial liquid dilution 1 week before the pond is released to purify the environment.

2. Water purification of loach breeding.

3 10 days before the loach seedlings are stocked, the dilution of Yifuyuan aquatic EM bacteria solution, one mu of water surface and one meter depth of water production EM bacteria are diluted and then splashed on the water surface. Depending on the water quality, once in the first 15 days, once in the next 1 month, where the water quality is poor, the splashing time should be appropriately shortened;

3. Handling of ear material:

Since the ear material is granular, you can spray the bait with 200 times the dilution of Yifuyuan aquatic EM bacterial liquid, spray the humidity to a degree, and feed it immediately to avoid scattering. It has a very significant effect on gastrointestinal diseases and improving the digestion and absorption of feed.

4. Treatment of organic fertilizer and manure

The organic fertilizer (grass liquid fertilizer) and manure to be put into the water body should be treated with Yifuyuan aquatic EM bacterial solution with a ratio of 1:200, and then it can be put into the water surface after fermentation.

5. Loach disease prevention and control: If there is a phenomenon of loach flooding, you can use the diluent of Yifuyuan bacterial solution to evenly splash the water surface, which can be improved in 3 5 hours, and the loach will return to normal. After that, you can splash again 1 2 times every 1 2 days.

Individual fungal diseases, bacterial enteritis, gill rot, printing diseases, etc. can waterlogen the diseased fish, and directly rub the lesion with 10 50 times of Yifuyuan bacterial liquid, and you can also use 100 150 times dilution of Yifuyuan bacterial liquid to soak the sick loach (with a slight floating head), and it can be cured after a few days.

Pond conditions: The pond is suitable for an earthen pond with an area of 1-2 acres, which requires convenient inlet and drainage, leeward to the sun, and anti-escape facilities around the pond. The depth of the pool is 80-100 cm, the silt at the bottom of the pool is 15-20 cm thick, and the water depth is maintained at 30-50 cm. The water inlet is about 20 cm above the water surface, the overflow is located at the normal level of the pond, and the drainage outlet is located at the bottom of the pond.

The water inlet, overflow and drainage outlet are blocked with dense mesh cloth, and the bottom of the pool is inclined to the drainage outlet, and the fish slip connected with the drainage outlet is arranged, with an area of about 5% of the area of the bottom of the pool, 30-35 cm lower than the bottom of the pool. Aquatic plants such as duckweed and water hyacinth are put in the pond, and the coverage area accounts for about 1 4 of the total area of the pond.

Fujian Nanping Sanjiang Taiwan loach seedlings sell seedlings and provide breeding technology can be consulted.

OK. Loach farms should choose places with convenient transportation and certain water source conditions, and it is better to be close to rivers and streams, and it is also possible to use groundwater. The pond area will not be flooded during the high water season, the pond is relatively empty, and it is best to have no deciduous trees around the pond to ensure lighting, and no leaves fall into the pond to cause pollution.

Loach ponds are similar to fish ponds, so if there is an existing pond, it can be used with a little protection, and if there is no ready-made pond, it needs to be rebuilt.

The loach is very active, very flexible, and good at escaping, so in the process of breeding loaches, it is necessary to do a good job in the management and preparation of loach escape, and in the water inlet and drainage, as well as the water volume control, we must carry out detailed observation and strengthen management.

In the summer rainy season, do a good job of water control, do a good job of drainage, water mesh to prevent escape, drainage and water inlet diagonal setting, you can do some plastic simple fence around the farm, to prevent loach natural enemies, snakes, rats, etc. from invading and stealing food.

The cultivation of loaches needs to pay attention to pond conditions, pond disinfection, loach seedling feeding, feed feeding, and water quality control.

1. Pond conditions.

At present, artificial breeding loaches are mostly cultivated in cement ponds, and the pond conditions require an area of 2 to 3 acres, with a water depth of 50 to 60 cm, and a thickness of 15 to 20 cm of fertile mud at the bottom of the pond. Moreover, environmental factors such as drainage and irrigation, transportation, sunlight, and water quality should be considered in the selection of pond sites.

2. Disinfection of clear ponds.

Some grasses (such as ryegrass, reeds, etc.) can be planted around the pond at a position of about 1 cm from the shore for shade and search, which is also good for water quality cultivation. Before the seedlings leak into the pond, splash the whole pond with quicklime (150kg per mu) for pond disinfection, and when the pond water is green, you can put the seedlings.

3. Loach seedlings are put in.

Under normal circumstances, the stocking density of loach seedlings is 800 to 1000, and the micro-flowing conditions can be appropriately increased. Note that loach seedlings of the same batch of hatching specifications should be stocked in the same pond to ensure balanced growth of seedlings and improve survival rate.

4. Feed feeding.

The loach seedlings that have just been put in the pond only need to be fed with some easily digestible concentrate feed such as cooked egg yolk, soybean flour, and soybean cake in moderation. When the seedlings grow to 1cm, they can already prey on small insects in the water body, and then they can be fed some cooked wheat flour, bran and minced fish, shrimp and other feeds, 3 to 4 times a day. In addition, in winter, when the water temperature is lower than 10, it is not necessary to feed, at this time, the depth of the pool water should be appropriately reduced, and the pool water can also be dried first and then spread a layer of straw at the bottom of the pool, so that the loaches can safely overwinter.

5. Water quality control.

When the loach species first enter the pool, the water depth of the pool is kept at 10 to 20 cm, and then with the growth of the loach species, the water level is gradually deepened to the due depth, usually shallower, and can be deepened when it is hot and high, and often inject new water to maintain a good water environment. If a loach is found swimming to the surface of the water to vomit air, it should be filled with new water or oxygenated measures should be taken in time.

Hello, dear, pit pond loach farming, the benefit is very good. 1.In the selection of breeding sites, first of all, we must choose a good water source, the water quality should be fresh, and the water source should meet the needs of aquaculture.

2.The pond of the pit pond should be surrounded by about 50cm above the water surface, and the simple imitation loach pond dug into the pond should be tamped hard, so as to avoid the collapse of the loach pond in the breeding or the destruction of the loach pond due to floods and floods, resulting in unnecessary breeding risks and losses.
