How to reduce the feed coefficient of fish and shrimp
The feed coefficient is also called the meat increase coefficient, which is one of the most commonly used indicators to evaluate the effect of feeding fish and shrimp. Refers to the ratio of the total amount of feed during feeding and the weight gain of fish and shrimp during this period. To put it simply, it means “a few kilograms of feed is used to grow 1 kilogram of fish and shrimp.†The smaller the figure, the better the quality of the feed. If the number is larger, it means that the quality of the feed is worse. How to reduce the feed coefficient of raising fish and shrimp? The key points to pay attention to the following points: 1, the quality of feed and molding. Good feeds come from good raw materials, and must meet the nutritional requirements of fish and shrimp, get a nutritional balance; at the same time, according to the feeding conditions of fish and shrimp, it is necessary to make the most appropriate different forms of feed for each stage, according to different habits to produce dry granules or Wet granules to avoid rapid dissolution loss after feeding, thereby reducing consumption. 2, feed quality and preservation. The feed itself has high nutrient content and raw materials are fresh, which is in line with the physiological needs of fish and shrimp. At the same time, it should ensure that it is not deteriorative, not rotten and does not produce bad odor. 3, feeding appropriate amount of law. Feeding to achieve appropriate, uniform, according to the weather, water quality, do a small amount of multiple feeding, try to avoid a large number of feeding. 4, breeding water quality to ensure. Fish and shrimp pond water should be clean from pollution and corruption, especially the water should have sufficient oxygen content. Therefore, proper oxygenation and water change are very important. Some people have detected that when the oxygen content of carp rose from 0.5-2 mg/l to 3-6 ml/l, the feed coefficient dropped by a factor of two.
