Mixed-breeding black pheasants are collocations. Utilize Ukrainian side to eat fish, eliminate the wild fish in the pool and turn it into harm. Therefore, the specifications of Ujaya should be less than the economic fish cultured in the pool, and cannot be equal to or greater than 1/3 of other cultured fish, otherwise it will be eaten by Ujungmai. It is the disparity in the size and appearance of the same species in Uzbekistan and the phenomenon of eating too much. Umbellum is not tolerant of high temperatures and likes to hide in the grass to catch the fish in the past, so after the beginning of summer, we must plant water hyacinth and other floating plants in the pool. The occupied area should be about one-tenth, not too much. In the summer flowering stage of Ujwah, the activity ability is not strong, and aquatic plants cannot be left in the breeding pond, because the plants often trap the fish, affect the eating and eating, hinder growth, appear frail or the individuals are too small, but are eaten by peers, or mutual Tears and other diseases such as water mold.
Baits should be fresh and live, rotten, and can not be fed. Sometimes they will be discarded by black mussels and sometimes cause fish diseases. In order to ensure that there are enough small baits, fertilize regularly, maintain a transparency of 25 cm, cultivate good plankton, promote the growth of wild fish as soon as possible, and promote their multiplication.
The larger the individual Ukrainian dragonfly, the more bait required and the lower the return on production value. Therefore, when Uzbekistan grows up to the listing standards, it will be sold as soon as possible. Capture large and small, catch up with small supplements. The amount of mixed feeding is: According to the production of wild fish per 667 square meters of water, about 15 tails are put in discretion. Ponds rich in wild fish can be put more Ukrainian.
Diseases of black locust are more common with watery mildew and white skin disease. The reason for the disease is that they kill each other and cause bacterial infections. If it is not injured, it is very difficult to get sick. The reason for killing each other is that there is not enough food and the fish are dead or injured.
The bait is sufficiently fast and the bait is not enough to fight; when it is not dead, the disease is two-in-one, and the watery mildew is often favored. When the main fish pond is a supporting role, it has a lot of credit for swallowing the miscellaneous fish; it eliminates the consumption of bait and miscellaneous fish and reduces the fish disease.
