What are the precautions for cage fish farming? Master these key points

Cage fish farming is an emerging farming model in recent years. It mainly uses original ecological lakes, rivers, reservoirs, rivers, sea areas and other waters to place cages for farming. Its advantage is that it can make full use of nature's products to obtain benefits, and it does not pollute the environment. However, there are several points to pay attention to when cage farming, otherwise the losses will be severe. Below are some points to note compiled by Qinnong.com, hoping to help everyone.

1. Fish species selection

In fact, if the farming technology is proficient enough, any fish species that can be farmed in ponds can also be cage-farmed, but in order to obtain the greatest economic benefits, we still have certain selectivity for fish species. First, we should make choices according to the water conditions where the cages are placed. It is best to choose fish species with strong adaptability, fast growth, high profit returns, and strong resistance for farming. Multiple species can be mixed for farming, which can utilize water resources to a greater extent, improve the environment, and increase economic benefits.

2. Feed selection

The food source of fish in cages is all through artificial feeding, and they can basically rarely hunt for themselves, so feed selection is crucial. It affects the growth and survival of the entire fish population. Since in most cases we use a multi-species mixed farming model, different species of fish have different feed requirements. There are herbivorous fish species, carnivorous fish species, and omnivorous fish species, so we must plan reasonably and choose high-quality, low-cost, palatable, and nutrient-rich feed.

3. Farming technology

The technical requirements for cage fish farming are relatively high because it is an intensive, high-density new farming method. Therefore, we can improve our farming technology through various trainings, and through practice learn and understand the structures, usage methods, feeding methods, and disease and disaster prevention methods of various cages. At the same time, we should also learn more about how others farm and other precautions in farming, so as to summarize a better exclusive farming method.

4. Density management

Cage farming itself is a high-density farming method, but this must also be controlled within a certain range. First, we need to plan the density according to the natural conditions of the water area. Second, in the same water area, we cannot carry out continuous farming for many years. The cage placement area can be changed every other year, which can reduce the occurrence of diseases.

5. Disease and disaster prevention

Another point to note in cage farming is diseases and disasters. There are many common fish diseases, but we mainly prevent and control them through prevention. During normal feeding, mix in an appropriate amount of agents that enhance resistance or prevent and control diseases for feeding. Disasters mainly include sewage disasters, floods, and droughts. For sewage discharged into the farming area, the losses are relatively large, so we must carefully observe the discharge of surrounding sewage, strengthen management, and carry out sewage purification treatment. Natural floods and droughts are both very serious hazards. At best they cause the fish population to escape, and at worst they cause mass death of the fish population. We can set up a flood warning system near the farming area, always pay attention to weather forecasts, and promptly prepare to move, lift, and sink the cages to minimize losses.
