Eel feeding has to pay attention

1, set up a simple feeding basket. In order to avoid crawling back and forth during feeding, feed can be spilled in the pool. Simple feeding baskets can be used. The baskets are made of plastic or wood, and bamboo or wooden nails are nailed to the bottom plate of the baskets. The distance between the nails is such that the neck can extend and the body cannot enter. The bait is placed in the bait basket so that the clam can only stick its head into the feeding. 2, suitable for feed size. When eating, first bite the food and then submerge into the water to swallow. If the food is too large, it is inconvenient to ingest. Therefore, it is best to make pellet feeds suitable for large and small clams. When the weight is less than 10 grams, the mouth crack 0.5 cm to 1.1 cm, requires a feed diameter of less than 0.5 cm, a length of less than 1 cm; when the carcass weight of 10 grams to 50 grams, cracks 0.7 cm to 1.4 cm, requires a feed diameter of less than 0.7 cm , Length less than 1.2 cm; carcass weight 50 grams to 150 grams, mouth crack 0.8 cm to 2 cm, requires feed diameter less than 0.8 cm, length less than 1.4 cm; carcass weight 150 grams or more, cracked in more than 1 cm, require feed The diameter is less than 1 cm and the length is about 1.5 cm. According to the palatability feeds fed in different specifications, the utilization rate of bait can reach more than 90%. 3, add adhesives. Adding binders in foods, such as carboxymethyl cellulose, gluten, algae, konjac flour, etc., can enhance feed elasticity and cohesiveness, and can not easily spread in contact with water, and effectively improve the utilization of food. 4, reasonable feeding. The protein content of juvenile bait is required to be 50%, and that of juvenile bait is about 45%. Feeding throughout the year should be based on the principle of “two light, medium weight”, that is, less feed in spring and late autumn, and more feed in summer and early autumn, and generally 70% to 80 percent of annual feed in summer and early fall. %.鳖 鳖 鳖 鳖 鳖 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜. The amount of feeding should be reasonable. Too little will affect the growth of earthworms. Too much will cause waste. Generally, artificial diets for young calves are 5% to 8% of body weight and 3% to 5% of calves. If fresh animal food is fed, it is 10% to 15% of body weight, and it is advisable to eat within 1 hour after feeding. 5. Keep food in a quiet environment. After being fed with food, a large amount of food is eaten on the food table. If it is disturbed, it will immediately sneak into the water, causing the food to be scattered into the pool and wasted. Therefore, after feeding the bait, it is important to keep the environment around the pond clean. (Source: China Fishery News)
