What fish is suitable for cage culture? 1. At present, there are many kinds of cage culture objects in China. In addition to the traditional "four big fish", carp and tilapia have also become conventional breeding objects.

2. In addition, there are gobies, crucian carp, bream and snakehead.

3. The breeding density is generally determined according to the water quality conditions, the characteristics of breeding objects and the difficulty of bait sources. Generally, fish (such as silver carp and bighead carp) that are filtered and fed without bait are cultured, and the stocking density of fish species is 1-3kg/m2, that is, if the size of fish species in the box is 50g/ fish, the number of fish cultured is 20-60 fish /m2. Edible fish (such as carp and grass carp) are generally stocked at the rate of10-15 kg/m. When the fish culture specification is 100g/ tail, the stocking amount should be 100- 150 fish /m2.

4. It can be multi-species mixed culture or single culture.

How much does it cost to raise fish in cages? 1, the cost of feed.

2. The cost of fry.

The cost of fry refers to the cost of buying fish in cages. If the market price is around 0.5 yuan, you need 1.200 yuan to buy fry.

3. Other expenses.

Is it profitable to raise fish in cages? From the above analysis of the cost and profit of cage fish culture, we can see that the profit of cage fish culture is very good and the breeding prospect is very broad.

Characteristics of cage fish culture: alias "cage fish culture" is a method of assembling synthetic fiber net or metal net into a box with a certain shape and specification and setting it in a water body suitable for fish culture. Cage fish culture is a new technology in the development of intensive aquaculture in the world today. This method has the advantages of high yield, low cost, less investment, convenient management, land saving, water saving, energy saving, effective development of fishery waiting points in rivers and lakes.

At present, cage fish culture has spread all over all kinds of large, medium and small waters in China, and has become a new fish production model with broad prospects and great production potential.

Cage fish culture is the adjustment of China's fishery structure in recent years, which is of great strategic significance to alleviate the environmental pressure of cage fish culture in ports and accelerate the construction of fishery industry. Cage fish culture is also a good way to promote fishermen to change careers, which will promote the development of fish culture in China. Therefore, cage fish culture will develop rapidly in China. Although there are still some problems in cage fish culture, the development prospect of cage fish culture is bright.
