1. Loachy Loach The loach is an omnivorous fish that feeds on 5 pairs of well-developed tentacles. The tips of the tentacles have taste buds that can discern bait smell. Loach has a habit of nocturnal feeding, likes to feed in the evening or in the middle of the night and during a quiet day, after artificial training can be changed to feeding during the day. The peak of food intake is from 7am to 10am and from 4pm to 6pm, and from 10am to 12pm is another peak of food intake. In different water temperature conditions, the food intake of the loach is also different. When the water temperature is between 25°C and 27°C, the loach's appetite is strong. At this time, the food intake is about 10% of the body weight. When the water temperature is lower than 8°C or higher than 35°C, the loach does not move and enters the overwintering and over-eating stages respectively.
II. Feeding of bait in different feeding stages
1. The newly hatched seedlings were hatched on the third day and the yolk sac disappeared and entered the feeding stage. At this time, some substitute feeds, such as egg yolk and soy milk, should be fed. Every one million larvae are fed one egg yolk, or every 100 million larvae are fed 100 grams to 150 grams of soy milk (calculated on the wet weight of the beans). In addition, some plankton, such as rotifers, may be fed, and the density of the rotifers should be brought to more than 5 per milliliter of water. The newly hatched seedlings can enter the pond after 3 days to 5 days.
2. One week before the seedlings were fed to the seedlings in the lower pond, 150-200 kg chicken litter or pig manure was used for the ponds per mu. After Xia Tang, three to four soy milks (0.5 kg to 0.75 kg of dried soybeans per 100 square meters of water) should be splashed three times a day to cultivate rotifers, leeches, etc. for loach.
3. After about 20 days of cultivation, the seedlings are grown to a length of 2 cm and enter the breeding stage. In addition to adding natural food at the time of feeding, artificial feeds such as fish meal, silkworm cocoon, pig blood, wheat bran, bean curd residue, soybean cake, and larvae must be fed. When feeding, wheat bran, bean cake, small junk fish (need to be minced), blood meal, etc. should be mixed with a small amount of flour to make a granular diet, in which the ratio of animal components to plant components is 5:3. At the beginning, it can be cooked and stirred. As the loach grows, it can be gradually changed to raw mix. As the water temperature rises, the amount of feed should be increased in a timely manner. After a month or so of feeding, the body length of the loach can reach 4 cm to 5 cm. At this time, the loach can be transferred to the cultivation stage.
4. Chengyu's dietary feeding into clams comes from a wide range of sources. Animal foods include quail, fly larvae, snail meat, animal viscera, silkworm pupa powder, blood meal, etc.; plant foods are rice bran, wheat bran, bean dregs, pancake, soybean powder, corn flour, cooked hawthorn, vegetables, stems and leaves. Cheng Yu like to eat plant foods, animal feed and plant foods should be controlled at 2:3. Feeding should be fixed, timed, and quantified.
