Description
Technical field
The invention belongs to technical field of aquaculture, are related to a kind of ecological culturex, specially a kind of Micropterus salmonoides and
River crab mixes ecological cultivation method.
Background technology
Crab is also known as river crab, is fresh water crustacean, grows up in fresh water, and river crab meat flavour is delicious, full of nutrition.River crab mesh
It is preceding by Chinese and the universally recognized cuisines of overseas people.Culture of Chinese mitten crab production on, also have been achieved with from quantity velocity profile to
The transformation of quality and efficiency is changed from " big crab farming " to " bringing crab up ", has especially more been focused on ecological, safe and environment-friendly, strong
The cultivation of health, nuisanceless aquatic products, it is also higher and higher to the quality requirement of aquatic products.
For now, simple pursuit in the past that high density launch, the small dimension commodity crab of high yield, there is no
Competitive advantage, in response to the market demand, it is difficult to sell discomfort, and market price is low, and culture efficiency is poor.Demand currently on the market
Be, high quality, big specification high-quality crab, and be also the trend of development, not only product is fast-selling for it, and price is high, cultivation effect
Benefit is good.Crab has been supported, has brought crab up, has supported high-quality crab, has supported health crab, has supported nuisanceless crab it is necessary to carry out the breeding way of health.It is so-called
Healthy aquaculture refers to the biological property according to river crab, instructs crabs production, as river crab to build one with ecological principle
A good ecological environment for being conducive to river crab growth and development, makes river crab reduce disease to the maximum extent during growth and development
Occur, the commodity crab formed.Pollution-free, individual is big, and the full cream fertilizer of Huang has good quality.Carry out innoxious management, it is ensured that river crab
It cultivates the whole quality safety from pond to dining table and people is allowed to be able to eat the high-quality crab trusted.Only in this way, product could be in great demand
Without hindrance, enterprise can just develop, the economic benefit and social benefit that cultivating river crab could obtain.
In cultivation is put into practice, changing hatch fish roe that water is brought into and changing due to water brings fry etc. into, can exist in pond
On the one hand many small fish, these small fish rob food river crab bait, water oxygen are on the other hand also consumed by, to influence river crab
Growth.Micropterus salmonoides are a kind of predacious fishes, and the small individual aquatic animal such as small fish in eating water does not rob food feed for river crab,
And it is received by the market very much at present.
Invention content
The purpose of the present invention is：For overcome the deficiencies in the prior art, a kind of yield and matter that can ensure river crab is obtained
Amount, and resource utilization is improved, increase economic well-being of workers and staff, the present invention provides a kind of Micropterus salmonoides and river crab to mix ecologic breeding side
Method.
Technical solution：A kind of Micropterus salmonoides and river crab mix ecological cultivation method, the described method comprises the following steps：
