In 20 14 years, the price of crayfish fry changed at 5- 10 yuan/kg; 20 15 years, and the price range is 8- 15 yuan/kg; By 20 16, the price of shrimp seedlings had risen to 15-20 yuan/kg, and the highest price had reached 35 yuan/kg. In 20 17, the growth rate of crayfish fry was relatively large, which was mainly caused by many factors such as the increase of culture area and the decrease of shrimp fry number. But as far as the current price is concerned, most farmers still think it is acceptable. With the price of shrimp fry rising, the cost of crayfish culture increases, which makes farmers more natural breeding shrimp fry to cope with the price increase, and farmers with poor natural breeding technology may reduce or give up breeding.
The second reason is the yield, area and culture level.
Choosing to breed lobsters is to see the hot market, and blindly invest if you don't know the breeding technology, thinking that you only need to enclose the land and put in shrimp seedlings. In fact, the planning and construction of lobster and shrimp ponds, the cultivation environment, when to plant seedlings, when to feed and when to fish all determine the output and size of lobsters. However, I lack technology and management, and I don't even understand the proportion of feeding, the disinfection of shrimp ponds, etc. Even if there is no natural disaster in good weather and I don't understand the growth habits of crayfish, the output is not proportional, and few farmers can persist in breeding for several years.
Because of its strong reproductive ability and wide adaptability, crayfish was once over-bred and flooded, which led many people to think that crayfish is easy to breed. In recent years, with the sharp increase of crayfish consumption, the resources of wild crayfish have decreased sharply. At present, the crayfish supplied on the market mainly come from breeding. The economic benefit of crayfish is high, the market continues to be popular, and there are more and more crayfish farmers.
Reason three: the whole country is rushing to the horse.
The culture area of crayfish will continue to increase, but the concentration of culture and sales will be higher due to the restriction of fry supply. In the early stage of aquaculture, there will be a sales price peak before the May meeting due to the lack of shrimp seedlings and adults. In the middle of aquaculture, due to the concentration of shrimp, it is estimated that the price will all fall back; In the late stage of aquaculture, the supply of adult shrimps is reduced due to hibernation, and the price is expected to rise steadily, but at this time, the consumption is greatly reduced, and there is no market for it. It is predicted that the consumption enthusiasm will continue to rise in 20 17, and a crayfish consumption boom will be set off from Heilongjiang, many cities in the middle and lower reaches of the Yangtze River and Hainan.
