Advantages and disadvantages of fish culture in cage

Cage fish culture is now a very popular fish culture model in our country. It is basically distributed all over our country, and cage fish culture is relative to the traditional fish culture model. It has many advantages, and it is also the main reason why many people choose cage fish culture. However, cage fish culture also has some shortcomings, so what are the advantages and disadvantages of cage fish culture? The following editor will give you a brief introduction, let's have a look!

First, advantages

1. Low cost and high output

When carrying on the cage fish culture, although we need to prepare the corresponding cage according to the culture quantity, put into the cage cost. However, compared with the traditional fish culture model, the cost of cage fish culture is lower than that of traditional fish culture. Whether in breeding, management or fishing and other aspects, the cost input is relatively small. And the output of cage fish culture is also more, under normal circumstances, cage fish culture is carried out in an area of about 40 square meters. Then the production of most fish can reach almost tens of thousands of kilograms.

2. Saving land and high price

Cage fish culture is not subject to geographical restrictions, in the traditional pond fish culture, if there is no pond, then need to occupy land to develop ponds. On the other hand, fish culture in cages can be carried out directly in rivers and reservoirs, without the need for land and water. At the same time, in the traditional fish culture, the need for aerator, bait machine and other culture equipment, in the cage fish culture is basically not needed. And the overall quality of cage fish culture is relatively high, so the market price is also higher than the traditional fish culture fish.

Second, shortcomings

1. Inconvenient use of drugs

The disease resistance of most fish is still relatively poor, so when we raise fish, we need to often put in drugs to prevent disease. In the cage fish culture, if there are parasites or viruses, it is not only inconvenient to put drugs. And the dose of the drug is also more than ten times higher, which is very disadvantageous to the stability of the drug and the safety of culture. If the weight is relatively large, it will also affect the new metabolism of fish. And in recent years, the focus of the state's attention in environmental protection, if the procedures are not complete and carried out privately, it may be eliminated.

2. High proportion and difficult to prevent disasters

As I just said, the proportion of fish culture in cages is relatively high. The density in each cage is relatively high, so the requirements of natural bait for fish will also be increased, and if cultured in a large area, natural bait will be relatively scarce. And compared with traditional fish culture, cage fish culture is not like pond fish culture, which can well control natural disasters, natural disasters and so on. For example, if there is a flood, then the cage can not be rescued, and the breeding will fall short of success.

The above is a brief introduction to the advantages and disadvantages of cage fish culture. That's all for today's introduction. This article is for reference only. I hope it can help you all.
