Local governments and fishery administrative departments should organize crab trade associations, build leading enterprises, and assume the important responsibility of maintaining and building crab brands; Breeders or leading enterprises should register trademarks for their crabs as soon as possible; For famous brand hairy crabs, it is necessary to implement a certificate system, strengthen quality management, cross the threshold of "market access", and set up a relatively fixed famous specialty store or e-commerce platform, so that producers, middlemen and distributors can gradually form a relatively stable one-stop sales network and enhance the credibility of hairy crabs in the market and consumers.

(2) limiting the scale

For the existing farmers, on the one hand, it is necessary to ensure the sustainable development of river crab breeding industry and reduce it appropriately, from emphasizing "large quantity" to "emphasizing moderate quality and quantity", or to other varieties of breeding.

(3) explore the market

From the perspective of sales channels, overseas markets such as Hong Kong require that the size of female crabs is 200 grams and that of male crabs is above 225 grams; From the perspective of social purchasing power, the river crab with the specification of100 ~150g in big cities is a hot commodity; In medium-sized cities, river crabs with specifications of about100g are more popular, and small crabs with specifications of about 75g are the first choice for small town residents and rural markets. Therefore, farmers should organize production and sales under the premise of market positioning to ensure marketable.

(4) winning by quality

We must start from the source, establish safety awareness, start with maintaining and improving the production environment of river crab breeding, establish pollution-free river crab production bases, strictly implement pollution-free aquatic products standards in seedling raising, breeding, fishing medicine, preservation and storage and transportation, vigorously advocate and popularize "prevention-oriented" disease prevention measures, and limit the use of drugs. It is necessary to implement the principle of "big water surface, small groups, big individuals", and comprehensively implement a healthy ecological farming model based on planting aquatic plants and feeding fresh bait such as snails and small miscellaneous fish, so as to win the market and obtain high prices with high-quality crabs.

(5) polyculture and synergism

There are several ways of crab polyculture, single polyculture and multiple polyculture. Single species include Siniperca chuatsi, Pelteobagrus fulvidraco, Siniperca chuatsi, Monopterus albus, Misgurnus anguillicaudatus, etc., such as per mu (mu is an illegal unit of measurement, 1 mu =115 hectares). ) In the crab pond, 50 ~ 60 summer mandarin fish with a length of 3 ~ 5cm or 65,438+000 ~ 20 mandarin fish with a weight of 50 ~ 65,438+000 g are nested. After 5 ~ 6 months of breeding, 5 ~ 65438 commercial mandarin fish with a tail weight of 400 ~ 600g can be caught per mu. Multi-species polyculture refers to polyculture of some silver carp, bighead carp and allogynogenetic crucian carp. In addition to stocking crab species, a certain number of brooding shrimps or young shrimps are stocked, thus forming a compound ecosystem where fish, shrimps and crabs coexist, which plays the role of "the east is not bright, but the west is bright" and reduces the risk of single culture being affected by market factors.

(6) temporary culture and proliferation

Through temporary breeding and proliferation, it must be carried out under the premise of considering water temperature conditions, fishing difficulty and market. Choosing a better temporary breeding place (sufficient fresh water and dissolved oxygen) and feeding high-quality bait appropriately will increase the weight of river crabs slightly.
