Loach breeding technology

For breeding mud loaches, first of all, the harvesting and cultivation of seedlings must be well done. Seedlings are divided into autumn seedlings (white dew), descending seedlings (frost fall), cold seedlings (early winter) and spring seedlings (early spring) according to the season. However, there are many seedlings and cold seedlings with good quality, fast growth, and high survival rate. At this time, the seedlings resemble sand, so they are called “Laksa”. There are 16-20 thousand grains per kilogram. It grows densely on the surface of the mudflats. It can be used to “fish boots” made from linen to evacuate at the time of low tide. "Sand", put into the bamboo sieve to wash away the sediment, filter out impurities, put about 350 kg per acre, "Laksa", evenly sprinkled on the prepared site. After the beginning of summer, the weather began to be hot, and “Laksa” had grown to about 10,000 grains per kilogram. At this time, it was necessary to sparsely raise about 300 kilograms per mu. By the end of the year, the seedlings generally grow to 1,500-2,000 grains per kilogram. "Bao Doo" will continue to be dredged in the early spring of the next year. It will stock 250 kg per acre, and then raise it to the end of the year. When it reaches 60-100 grains per kilogram, it can be sold on the market. Muddy enemies suffer a lot from carnivorous fish such as carp, carp, sea bream, and dolphins. They often swim in and feed on seedlings. Therefore, they should be surrounded by bamboo twigs or branches and fish nets. In order to threaten fish admission. In addition, spotted snails, pelagic snails, and other wild small shellfish are often covered with dense silk on the surface of the site to absorb a large amount of nutrients to harden the slime and also to secrete toxic substances. Therefore, they should be removed in time when the tide is low to improve the muddy. Survival rate and growth rate.
