Feeding method for dollfish feed
Feed and feeding is a central part of the whole culture technology of giant salamander. The occurrence of polyposis and the survival rate yield have a close relationship with feed feeding. Therefore, we must pay attention to the feeding of bastard fish feed. First, the type of feed. The giant salamander is a carnivorous animal, and its natural bait resources are very rich, mainly fish, shrimp, frogs, shellfish, loach, chicken and duck embryos, lamb, beef, rabbit meat, quail, etc., artificial compound feed can use catfish feed, we have Developed into a dollfish artificial compound feed. The bait coefficient of natural baits raising adults is 3.5~6.3. The formula of feed for adult diets is 2.8-3.6. All localities can decide on feeding species based on local feed resources. Second, feeding. In order to improve the breeding efficiency of the giant salamander and reduce the feed cost, it is necessary to understand the ability of adults to digest, absorb, and utilize nutrients in the feed prior to feeding, in order to determine reasonable feeding. Reasonable feeding includes issues such as nutrition, growth, metabolism, physiology, ecological environment and feeding factors, feeding times, feeding methods, and feeding principles of giant salamander. 1. Feeding time and frequency. Under appropriate temperature conditions, the giant salamander is digested and absorbed. In general, it is fed for 2 to 3 days. If the humidity is lower than 10°C, it is fed once every 5 to 7 days. The giant salamanders are nocturnal, feeding at night, so the summer feeding time is 8 to 10 pm every day, and winter can be 6 to 8 pm. 2. Feeding amount. There are many factors influencing the feeding of the juvenile fish, such as water temperature, dissolved oxygen, water quality, diseases, feed varieties, and feed quality. Water temperature is an important factor influencing the feeding of the giant salamander. Because the salamander is a variable temperature animal, the body's physiological metabolism changes with the temperature of the water. In the optimum temperature range of the giant salamander, its feeding and growth are positively correlated with the increase of water temperature. In general, feeding above 12°C, the food intake is the highest at 18-23°C, and the growth is also the fastest. When the water temperature rises above 26°C, the food intake decreases, and it enters the "summer sleep" at 28°C or more. At the appropriate temperature and the same feed quality conditions, dissolved oxygen and water quality play a major role. Therefore, the amount of adult feeding should be determined by combining various factors. 3. Feeding methods. Feeding should be based on the biological learning and ecological habits of the juvenile fish to determine a reasonable feeding method. In order to improve feed utilization and reduce feed costs, feeding must adhere to the four-time feeding method, ie, timing, positioning, quality, and quantity. 1 Timing: It is based on the characteristics of nocturnal creatures learning to feed at night, but it should be advanced or delayed according to the season, water temperature, and water quality. General feeding time: 10:00 pm in the summer and 8 pm in the winter. 2 Positioning: To develop a position for feeding habits of the giant salamander can promote the centralized feeding of salamanders. The cluster feeding can not only increase the appetite of the salamander but also increase the appetite, but also reduce the dispersion of the feed and improve the feed efficiency. 3 Qualitative: If the feeding is artificial compound feed, it should be stored in a low-temperature, dry, damp-free place. Adults have different feed additives due to their different purposes. In order to increase the utilization of protein in feeds, the feed must be prepared with oils and fats, and fish oil and vegetable oils are generally required. The amount of oil added increases or decreases depending on the water temperature. Generally, when the water temperature is 18~23°C, add 5% of fish oil and corn oil. When the water temperature is 14~17°C, the amount of oil added is 5%~6%, which is lower than No fat is added below 12°C. Natural baits require fresh and clean, and must not be fed for deteriorating bait. Natural baits are ideal for feeds such as loach, cod, squid, and chicken and duck embryos. 4 Quantitative: According to different factors such as feeding, digestion, individual growth, individual size, water temperature, and water quality of the giant salamander, appropriate amount of feed should be given.
