Pay attention to scientific and reasonable feeding methods, not only conducive to the healthy growth of fish, but also save feed and effectively improve the efficiency of fish farming.
The feed pelleted pellet feed usually has a diameter of 2.5 mm to 8 mm and a length of 5 mm to 10 mm. According to the size of the fish, choose the appropriate particles, and select the feed with the appropriate protein content according to the nutritional needs of different cultured species. Herbivorous fish require 25%-30% of protein in feed, 30%-35% of omnivorous fish, and 35%-45% of carnivorous fish. The feed can be placed directly on the food table and fed according to the principle of "less-more-less" and "slow-fast-slow". According to the seasonal changes, adjust the bait rate timely. In spring, when the water temperature is low and the food intake of fish is small, it should be fed in an appropriate amount. When the water temperature rises above 15°C, the feeding amount can be gradually increased, and the daily feeding rate is controlled at about 1%. When the water temperature rises to about 20°C in summer, the daily feeding rate can be controlled at about 3%, but at this time, it is also a fish-family-prone season. Pay attention to proper feeding. When the water temperature rises to 25°C to 30°C, the fish have a strong appetite and the growth rate is increased. It is necessary to increase the feeding amount and the daily feeding rate can be controlled at 4%-5%. In autumn, the weather has turned cooler and the water temperature has been reduced. However, the water quality is still stable, and the fish continue to grow. The feed amount must be guaranteed. The daily feed rate can be controlled at 3%-4%. In winter, the food intake of fish is decreasing day by day. When the weather is fine (water temperature is above 8°C), a small amount of feed must still be fed to maintain the fish's plumpness. The feed should be properly kept. If it cannot be directly fed with moisture, it must be dried or dried before it is thrown. If it is deteriorating, it should not be fed again to prevent the fish from poisoning after eating.
Turfgrass, ryegrass, goosegrass and other grasses planted with green fodder should be timely harvested to prevent the aging of stems and leaves from being used easily. Some melon leaves and cabbage leaves should be cleaned before feeding. Feed small fish, can chopped or beating green feed, add 0.2% of salt and mix well, splash feeding, such as the melon leaves, cabbage, etc., chopped and cooked, stir in the appropriate amount of bran, soda, small Fish prefer to eat; feeding big fish can feed green feed directly. In general, the amount of fish fed before April is about 10% of the fish's body weight. From May to June, it gradually increases to 20% to 30%. From July to September, it is about 50%. The fish is eaten for 2 hours.
Feeds for cakes Feeds for feeds should be broken, soaked, grind after feeding, and fed with medium or large fish can be soaked in order to improve feed utilization.
Grain feed corn, etc., should be processed and crushed after feeding the fish; small grain of grain can be fed and fished after germination. The young grain white bud has high nutritional value, and the fish eat easily digested and absorbed, and the weight gain is fast.
Dregs feed for small fish should dip the dregs to soften the pulp; for medium or large fish, it should be fermented until it has scent. Feeding in small amounts at the beginning of feeding, and then gradually increasing, but it should not exceed 30% of the total daily feeding.
Animal feed maggots, fly maggots, and insects are all animal protein feeds for fish, and can be directly fed, or dried and processed into powder and then fed with other feeds. For bulk animal feed, it should be chopped, ground, and glued into small pellets.
Manure feed Chicken manure, pig manure, cow dung, etc. are good feed for fish. The feces can be ground and ground into powder, and then used in combination with other feeds in a certain proportion. The proportion is generally 40%-50% of chicken manure, 30%-50% of pig manure, and 50%-70% of cow manure.
