Tell me how to raise loach fish in the Tohoku region

Loaches seem to hibernate in winter, but the winter in the Northeast is long, and the growth period of loaches in the Northeast is short, so it seems that it is not easy to grow up.

1. Pond conditions. The cultivation pond is as much as possible is an earthen pond, the depth of the pool is about 50cm, the water color of the pool is yellow-green, the transparency is 20 25 cm, the pH is neutral or weakly acidic, and the dissolved oxygen is more than 2 milligrams of liters. The soil at the bottom of the pond should be compacted, and some grasses (such as ryegrass, reeds, etc.) can be planted around the pond at about 1 from the shore for shade.

2. Seed stocking. 7 to 10 days before the loach seed stocking, use kilograms of quicklime square meters to thoroughly clean and disinfect the pond. When stocking seedlings, it is necessary to select seedlings with neat specifications, strong physique, and no disease and no injury for stocking.

In general, the stocking density of loach species with a size of 5 7 cm is 80 100 square meters, and 5 8 square meters of crucian carp can be stocked in loach ponds.

3. Feed feeding. Loach is an omnivorous small fish, the feed is very wide, daphnia, earthworm, fly maggot, etc. are natural bait organisms of loach, and can be fed with rice bran, soybean cake, bean dregs, blood meal, wheat bran, etc. under artificial breeding conditions. The daily feeding amount of loaches was 1% of the total loach weight in March, 4% of the total loach weight in April and June, and 1% of the total loach weight in July and August.

4. Daily management. Check the loach activity and feeding situation every day, and do a good job of timing, fixed-point, qualitative and quantitative feeding. In addition, strengthen the management of pond patrols, keep diligent diaries, and make up for the damage of pond equipment in time to prevent escape.

Of course, doing a good job in disease prevention and control is also the key, and strive to achieve early prevention and early treatment of diseases. Regular sprinkling of quicklime and bleach powder throughout the pond can improve water quality and prevent the occurrence of fish diseases.

5. Water quality control. As the loach species grows, the water level should be gradually deepened, and a little more in hot weather. If bubble disease has occurred in loaches, 5 milliliters of salt water can be used to splash the whole pond, and a part of the old water can be discharged, and new water can be added to improve the water quality environment of the pond.

In addition, the high temperature pool water in summer is prone to hypoxia, so it is necessary to turn on the aeration equipment in time to increase the amount of dissolved oxygen.

6. Catch at the right time. In late autumn and early winter, when the water temperature drops to 10 15 and the loach feeds less, it can be fished. Generally, the method of draining the pool water is mostly used for artificial pooling.

In general, loach has strong adaptability, fast growth rate and short breeding cycle, which is very suitable for the aquaculture project of farmers. Moreover, the loach is delicious, nutritious, and in high demand in the market, as long as you find the right market, you can get a good profit from breeding.

OK. Loaches prefer to inhabit the bottom of still water, and often haunt the surface layer of silt rich in plant debris at the bottom of lakes, ponds, ditches and paddy fields, and are highly adaptable to the environment. The living water temperature is 10-30, and the water temperature of the most suitable source is 25-27, so it should be a warm-water fish.

When the water temperature rises to 30, the loaches dive into the mud for the summer. In winter, when the water temperature drops below 5, it is buried in the mud at a depth of 20-30 cm for wintering.

Loaches are multi-spawning fish. Under natural conditions, breeding begins in early April, and the spawning season is at its peak in May and June, and it continues until September. The temperature and climate of the Northeast can also meet the growth needs of loaches, so loaches can be farmed in the Northeast.

1. Cage farming mode, cage farming mode, aquaculture mode should be selected in the sunny sheltered lakes, reservoirs, and finally in the area with good water quality and slow beating, pollution-free area, the area of the cage can be large or small, according to the breeding environment. When feeding, lay a layer of fertilizer mud in the cage, and the height of the cage should be 30-40 cm higher than the water surface to prevent loaches from escaping, and the feeding is mainly artificial bait, so the stocked seedlings must be selected to eat artificial bait.

2. Pond loach mode, pond loach mode is the most common breeding method, which can be adapted to major regions, and can use ready-made ponds or rice fields and soil pits. Generally, it is required to have a pond with a length and width of 20-30 meters, the depth of the pond is within 2 meters, the water depth is 50-60cm, the pool is low and flat, and then the surrounding fence is used to prevent escape, cultivate water quality, and cultivate some floating plants. Then according to the seedlings above 3cm at a density of 500 catties per mu, after 3-4 months, you can **.

3. The lotus root pond breeding mode is similar to the rice field breeding model, and the lotus root pond aquaculture can also achieve one water and one land for two purposes, so as to achieve ecological farming. However, the slight difference in the rice farming mode is that there are small spines on the stems of the lotus root, which have been traumatized when the loaches are feeding and moving, which can easily lead to disease infection. Therefore, when using this model, we should pay attention to the number of raising, and second, we should choose lotus root varieties with fewer thorns.

4, rice farming mode, rice farming mode is to achieve ecological balance of a breeding method, Yuxiang to achieve a water dual-use, a place two cherries with which, loaches can be used in the rice field insects and floating plants for food, can play an excellent role in biological control, basically can not do pesticides, reduce environmental pollution. Rice can also absorb the excretion and secretion of loaches, reduce the use of chemical fertilizers, enhance water quality, and reduce the cost of farming. The two can produce truly pollution-free, pollution-free, green rice and loaches.

5. Cement pond breeding mode, cement pond aquaculture mode has the advantages of convenient feeding management, easy fishing and excellent regulation of water quality and water temperature. Generally, in order to facilitate management, each cement pool area is about 100 square meters, the depth of the pool is meters, and the bottom of the pool should be covered with a layer of 20-30cm thick soil to build a suitable growth environment for loaches. In addition, the cement pond must be dealkalized and disinfected after construction, so that the seedlings can be raised, otherwise the alkalinity of the water body will be too high, resulting in a large number of loaches dying.

Abstract Pro, in the Northeast to breed loach fish should first choose the right species, large body size and fast growth is the first choice. Secondly, it is necessary to establish greenhouse insulation, long-term low temperature is not conducive to the growth of loaches, and even leads to a large number of their death in winter, so we must pay attention to the temperature. In addition, since the loach cannot be raised in a cement pool, otherwise it will cause it to wear out its mouth and body, and it needs to be used in a swamp-like environment.

How to raise loaches in the Northeast.

Pro, in the Northeast to breed loach fish first to choose the right species, large body size and fast growth is the first choice. Secondly, it is necessary to establish greenhouse insulation, long-term low temperature is not conducive to the growth of loaches, and even leads to a large number of their death in winter, so we must pay attention to the temperature. In addition, since the loach cannot be raised in a cement pool, otherwise it will cause it to wear out its mouth and body, and it needs to be used in a swamp-like environment.

I am around Harbin, there is a ditch of ten acres of land, I want to use the loach can be, I don't know whether it is suitable for raising loaches, dear, this is okay, but there needs to be a warm shed, because the winter around Harbin is too cold, and the water temperature in winter should be controlled at about 10 degrees.

If the water depth reaches 1m5, will the loaches freeze to death?

Feasible, a depth of one meter and a half is most suitable for loaches.

Because the ditch is about 80m long and wide, I want not to feed feed, how big can it rise in a year, dear, if you don't feed it, this is not accurate, it may grow about 20 grams a year.

1. If you raise loaches at home, give it a large enough living space so that it can move freely.

2. Loach is a benthic species, and the bottom of the tank can be arranged for it with clean fine sand.

3. Before putting the loach into the aquarium, put it in a large basin and soak it in water for a period of time to spit out the garbage impurities, so as to adapt to the environment of the aquarium.

4. The filtration and aeration device in the aquarium should be able to work normally, and the loach also needs flowing living water and sufficient oxygen, and some aquatic plants can also be placed to increase the oxygen content of the water by photosynthesis.

5. The water temperature in the aquarium should be controlled at around 25 degrees, and a little salt can also be added to the water, which has the effect of sterilization and disinfection.

Of course, loaches can be farmed, and loaches are not afraid of the cold. You can pay attention to the "Taiwan loach" does not hibernate in summer, does not hibernate. For details, please pay attention to the official website of "Guangzhou Lianfeng Aquatic Products". Thank you! **There are more new technologies on loach farming.

If the temperature is too low, it is not easy to raise, and the best temperature for loaches is 20-28 degrees.
