Matters needing attention in cage fish culture
Cage fish culture is a new culture model in recent years, which mainly uses the original lake, river, reservoir, river and sea area to put cage culture. Its advantage is that it can make full use of the products of nature to obtain benefits, and does not cause pollution to the environment, but there are several points to pay attention to when cage culture, otherwise heavy losses. Here are some points that need to be paid attention to by the pro-agricultural network. I hope I can help you.
1. Fish species selection
In fact, if the culture technology is at home, as long as the fish species cultured in the pond can be cultured in cages, but in order to obtain the maximum economic benefits, we still have a certain degree of selectivity for fish species. First of all, we have to choose according to the water conditions of the cages we put in. It is best to choose fish species with strong adaptability, fast growth, high profit return and strong resistance to culture, and multi-species can be mixed cultured. in this way, we can make greater use of water resources and improve the environment and economic benefits.
2. Feed selection
The food sources of fish raised in cages are all fed artificially, and they are rarely able to hunt on their own, so the choice of feed is very important, which affects the growth and survival of the whole fish. Since in most cases we are in the mode of multi-breed mixed culture, then the feed needs of different species of fish are different, including herbivorous species, carnivorous species and omnivorous species, so we should plan reasonably and choose high quality, cheap, palatable and nutritious feed.
3. Culture technology
The technical requirements of cage fish culture are relatively high, because it is an intensive and high-density new culture method, so we can improve our culture skills through all kinds of training. and through practice to learn and understand the structure of various cages, use methods and feeding methods and disease prevention and disaster prevention methods, but also learn more about how others breed and other aspects of aquaculture attention. Thus summed up a set of better exclusive breeding method.
4. Density management
Cage culture is originally a high-density culture method, but it should also be controlled within a certain range. first of all, we need to carry out density planning according to the natural conditions of the water area, and secondly, we cannot carry out continuous culture for many years in the same area of water. We can change the area of the net every other year, which can reduce the occurrence of diseases.
5. Disease prevention and disaster prevention
Another thing to pay attention to in cage culture is disease and disaster. There are many common diseases of fish, but we mainly prevent and control them by way of prevention, and mix appropriate amount of resistance or disease control agents into the usual feeding. The disasters are mainly sewage disasters and floods and droughts, and the loss of sewage discharge into the breeding area is relatively large, so we should carefully observe the surrounding sewage discharge, and strengthen management, as well as sewage purification treatment. On the other hand, the harm of natural flood and drought is very serious. if it is light, it will lead to the escape of fish, and if it is serious, a large number of fish will die. we can make a good flood warning system near the breeding area, and always pay attention to the weather forecast. timely preparation for net removal, net lifting and net sinking to minimize losses.
