Case Analysis of Ecological Culture of Loach

This breeding base carries out the ecological three-dimensional breeding model, that is, making full use of the space, growing hollow vegetables on the surface of the water and raising Loach in the water. Different from the single Misgurnus anguillicaudatus culture, ecological culture is a compound culture method. Now the combination of Loach and hollow cabbage is a successful attempt, a typical case of combining vegetables with aquatic products.

Hengyuan Misgurnus anguillicaudatus breeding base began to release seedlings in the middle of May every year, according to the standard of 300 jin and 150 tails per mu. Before releasing the seedlings, the pond will be thoroughly disinfected, sprinkled throughout the pond according to the amount of 100 jin of quicklime per mu, flushed repeatedly for 3 times, and the seedlings can be released about a week later.

Misgurnus anguillicaudatus in the breeding process must pay attention to the three prevention, feeding and daily management, that is, disease prevention, escape prevention, bird prevention. In the aspect of disease prevention and control: regular water disinfection should be done to create a good water environment for Loach; when feeding feed, some special disease prevention drugs for Loach can be put in regularly. Anti-escape aspect: observe whether there are loopholes around the pool, find and fill it in time, surround a net at 20-30 centimeters away from the pool, prevent Loach from coming into direct contact with the surrounding soil, and minimize the chance of escape. In terms of bird prevention: most birds that eat Loach are second-and third-class protected animals in the country. In order to promote the harmonious development of human and nature, we strongly recommend that farmers give priority to prevention rather than hunting; farmers can encircle a thin net over the pond, which can effectively prevent birds from preying on Loach. Once the three precautions are done, the basic problems will be solved. Feeding: feed depends on the climate. When the water temperature is 20 Mel 30 degrees, feed according to 3% of the total Loach; when the water temperature is above 30 degrees, feed according to 4% of the total amount you go to; once every morning and evening, feed 35% of the day's feed at 6: 00 in the morning and 65% at 5: 00 p.m. Daily management: the key is to patrol the pool in the morning and evening to observe whether the net is damaged, whether there is an escape at the inlet and outlet, what the water quality is, and whether the ammonia nitrogen exceeds the standard; the pool water should be changed regularly, depending on the temperature; Loach should not be fed too much, it is appropriate to eat in two hours, an eating table can be built to observe the eating situation.

But in summer, the water temperature will be too high, which may adversely affect the growth of Loach. Therefore, we suggest that farmers put some aquatic plants on the water surface, if it can create economic value, so much the better. Generally speaking, asparagus accounts for the whole surface of the water with the best ratio of 1 to 3. The following is a brief introduction to the technical points of raising asparagus on the water surface: you can choose a space in the middle or corner of the water surface, fix it around with a wooden stake or bamboo pole and use a whole piece of sunshade net or foam in the middle (sunshade net or foam dig many small holes to make sure you can put the beads of hollow cabbage into it), and then use a rope around it to prevent the hollow cabbage from spreading.

The cultivation of bamboo leafy vegetables can save 20% Murray 30% of the feed, because bamboo leafy vegetables will attract some insects, which happen to be the natural active bait of Loach, and are more nutritious than feed, which is beneficial to the growth of Loach. The cultivation of bamboo leafy vegetables can also reduce the economic pressure of farmers, the cost of massive cultivation of Loach is relatively high, and the cost and profit can only be recovered by selling Loach at the end of the year, while the cultivation of bamboo leafy vegetables can help to reduce feed costs obviously.

Taking Hengyuan Loach culture base as an example, under the leadership of Pan Youfeng, general manager, we tried the ecological three-dimensional culture model of 10 mu, and achieved ideal results. According to 300jin per mu of land, the price of seedlings is 20 yuan / jin, and the annual output is about 1500 jin, while the average market price of the finished Loach is 18 yuan / jin. The cost of seedlings is 6000 yuan, the feed cost is 7000 yuan, and the cost of building a pond includes 3500 yuan for the transformation of rice fields and anti-escape nets, 2000 yuan per mu for labor, 1000 yuan for disease control and daily management, and the income is not less than 6000 yuan / mu. As far as asparagus is concerned, it can be harvested 15 times per square meter a year, and the average income per square meter is 2 yuan, which is 4500 yuan according to the planting area of 150 square meters per mu. Therefore, the ecological three-dimensional breeding model is a good choice. In the process of trying, the general manager played an important role in repeatedly trying to control the range of asparagus from 1 to 3 of the whole area. in this way, Loach has plenty of room for activity and cabbage has plenty of room for growth.
