At present, although the price of grass shrimp is uneven in the market, the overall market is quite stable and good.
Do you make money by raising grass shrimp?
1, because the supply of grass shrimp market is not large, the wild resources are limited, and the catch is decreasing due to the pollution of river waters, so the prospect of developing artificial breeding is promising.
Some experts believe that as long as it is properly raised, the benefit of raising river shrimp per mu is 6 -8 times or even more than that of raising fish.
2. It is understood that the cultivation of grass shrimp is not complicated. Generally, a pond with sand and mud at the bottom of the pond with a water depth of 1 m-1.5 m can be used as the cultivation pond of grass shrimp, and the pond should be close to the water source in order to drain water in time and increase oxygen.
Grass shrimp is omnivorous, it has strong reproductive ability and fast growth, and it can also be mixed with non-carnivorous fish such as silver carp and mud carp, which is well raised and has considerable economic benefits.
Therefore, it is profitable to cultivate grass shrimp.
Cost and profit analysis of grass shrimp culture
At present, grass shrimp is not a large-scale breeding variety in the market. Because it needs certain breeding technology and the yield per mu is not high, the market is generally sold as high-grade shrimp, so the specification requirements for listing are generally above 30 heads/kg.
Zhang Xin told reporters that the shrimp prices in the past four years are all good, the best time is more than 80 yuan/kg, and the worst time is 30 yuan/kg. In the year with the best price, he only raised one white water shrimp, which is equivalent to raising two shrimps a year.
Compared with the Penaeus vannamei raised before, Zhang Xin thinks that the price of grass shrimp is more advantageous and the profit is higher, but the cultivation technology is also more difficult. He revealed that there are basically no people around to cultivate grass shrimp, and most of the known places where grass shrimp is cultivated in Guangdong are extensive cultivation modes such as mixed cultivation, with the yield per mu ranging from100 to 200 kg. In fact, as long as the yield per mu of grass shrimp exceeds 300 kg, there are many failures in cultivation.
Although the sales market of grass shrimp is relatively narrow, it is generally not difficult to sell, although he is a single family in the surrounding area, and there are cars specially coming to pull goods when shrimp is produced.
Although the profit of grass shrimp is high, the technical difficulty of cultivation is also very high. The higher the price, the more difficult it is to cultivate shrimp in that year, and the profit and risk coexist.
Zhang Xin believes that the reason why he can achieve such a high yield per mu is mainly due to his small breeding area, intensive cultivation by one person, 24-hour guarding and some luck.
So what is the annual profit of cultivating prawns per mu? This is a problem that many people care about, especially the novice prawn breeder, who cares more about these problems.
According to the information provided by farmers, generally, more than 2,000 shrimps are put into an acre, and the shrimp breeding cycle is short, and two crops can be raised a year, so that more than 4,000 shrimps can be raised in an acre of shrimp pond a year. Not entirely, the shrimps have to give birth, so that the number of litters can reach more than 400,000, and they can be sold or raised by themselves, which will all be income. Overall, the profit of breeding is relatively high.
In the first year of breeding, the infrastructure cost should be deducted, which is the cost of trimming the shrimp pond.
The cost of shrimp ponds varies according to the difficulty of the project, but generally speaking, it needs about three or four thousand yuan, and the total cost of breeding equipment, feed and management needs about ten thousand yuan, and the total cost of breeding an acre is about thirteen thousand four hundred.
It's not a small investment project. Farmers can raise prawns in small quantities first, and then increase the scale of breeding when they are experienced.
