In the process of fish farming, it is very important to control the density of fish farming, which not only simplifies management and saves costs, but is also one of the important measures to achieve high yields. So how many fish should be raised per acre of water? Let’s learn more about it below. How many fish should be raised per acre of water? One acre of water surface can generally raise no more than one thousand fish fry , but the specific number depends on factors such as breeding conditions and fish species. Generally speaking, the smaller the fish species, the higher the breeding level and the better the water quality, the greater the number that can be raised. What technical points should be paid attention to in high-density fish farming? 1. Pay attention to dissolved oxygen Pay attention to the water quality and dissolved oxygen conditions in the fish pond. If you find that the water quality is deteriorating, add water in time to improve the water quality of the fish pond. The dissolved oxygen content per liter of water in a fish pond is generally required to be above 4 mg/L. If it is lower than 4 mg/L, the fish pond should be oxygenated. If we want to know the dissolved oxygen in the pond at any time, we can install a dissolved oxygen detector to monitor the dissolved oxygen in the water in real time. 2. Feeding Feed should be given at regular intervals and in fixed quantities to avoid overfeeding which may lead to deterioration of water quality. At the same time, a scientific and reasonable feed formula should be formulated. The feed should be rich in nutrients such as protein and vitamins to avoid the occurrence of fish health problems. 3. Water quality management Test water quality regularly to ensure stable water quality. During the breeding process, microbial preparations , water quality improvers, etc. should be added appropriately to improve the water quality. 4. Disease prevention and treatment Common diseases include gill rot, red skin disease, hemorrhagic disease, etc. Disease prevention and control can be carried out through a variety of methods such as drug treatment and microecological preparations, but attention should be paid to the dosage and method of use of the drugs to avoid adverse effects on water quality and fish species. 5. Daily pond inspection Patrol the pond once every morning and evening to observe water color, fish activity and bait eating conditions, and deal with problems in a timely manner. 6. Rotary catch and release The method of catching and releasing in rotation, that is, releasing enough fish at one time, fishing in batches, and catching the big ones and leaving the small ones for release, is one of the important measures to achieve high yield and high density. In general, there is no accurate answer to how many fish should be raised per acre of water surface. In actual operation, flexible adjustments should be made according to specific circumstances. If conditions permit, high-density fish farming, attention should be paid to the relevant technical key points to achieve efficient, stable and sustainable development of high-density fish farming.
