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. The food intake of loach is different under different water temperature conditions. When the water temperature is between 25°C and 27°C, the appetite of the loach 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. Mudworms do not eat or move and enter the winter and summer stages respectively. Second, feeding methods for different feeding stages 1. The newly hatched seedlings were fed. On the third day after hatching, 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 to 5 days. 2. Seedlings are fed. One week before Xia Miao Xia Tang, 150-200 kg of chicken manure or pig manure was used for the ponds per mu of pond surface. After Xia Tang, sprinkle 3 to 4 soymilk (0.5 kg to 0.75 kg of dried soybeans per 100 square meters) on a daily basis to cultivate rotifers, leeches, etc. for loach. 3. Kind of feeding. After 20 days of cultivation, the seedlings grow to about 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 rearing, 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. Cheng Hao's feeding. The source of bait raised into clams is relatively extensive. Animal diets include quail, fly larvae, snail meat, animal viscera, silkworm pupa powder, blood meal, etc.: The vegetal baits include rice bran, wheat bran, bean dregs, pancake, soybean meal, corn flour, cooked hawthorn, vegetables, stems and leaves. Cheng Yuxi eats food and animal feed. When feeding, animal feed and plant food should be controlled at 2:3. Feeding should be fixed, timed, and quantified.
