Description
Technical field
The present invention relates to marine products seedling breeding technical field, particularly relate to the factorial seedling-culturing method of a kind of Ma Youyu.
Background technology
Traditional mariculture kind is by sparid class, perch class, grouper, yellow vertical silvery pomfret etc., then develop into again cobio, large yellow Crocker, U.S. snapper, dragon wholesale, hybridization dragon and tiger spot etc., the seedling-cultivating method that these marine products adopt is to carry out ecological breeding in outdoor outdoor pond mostly, this seedling raising manners is subject to the impact in region, weather and season very large, very unstable, easily cause the postponement of seedling raise period, cannot need to produce seedling according to breeding production, and culturing time shortens then, has seriously restricted the development of mariculture industry.Current traditional breed variety, its market demand relative saturation, and also culture benefit is low, lacks new substitute species.
Ma Youyu is a kind of blubbery famous and precious fish; the trace elements iron of protein, unsaturated fatty acid, DHA, taurine and the needed by human body containing than general ocean fish class, phosphorus, calcium are all many; and unsaturated fatty acid, taurine, there is the effect that reduces cholesterol and prevention cardiovascular and cerebrovascular disease.Ma Youyu is mainly distributed in Coast of Guangdong Province, but its catching amount is few, on market, is hard to buy.Ma Youyu is one of the current most significant end fish new varieties that can carry out artificial breeding and cultivation, has wide market prospects.
Yet, use conventional methods is that outdoor ponds is carried out ecological breeding, because its water quality environment, illumination condition, useful food organisms and pest are all difficult to control, be subject to environment, climatic influences very large, thereby cause, survival rate of seedling is low, the uniformity of growing seedlings is low, and product quality is poor, cannot meet the demand in market, and due to artificial excessive feeding intake and excessive use chemicals in breeding process, causing water pollution, a large amount of sewage discharges causes further pollution to environment.
Therefore, for the deficiencies in the prior art, need the controlled Ma Youyu seedling growing process of research and development large-scale production and process badly, thereby promote the industrialization sound development of high-end culturing marine products industry.
Summary of the invention
The object of the invention is to avoid weak point of the prior art and a kind of high-efficiency environment friendly is provided, the quality better of growing seedlings, survival rate are high, the factorial seedling-culturing method of the Ma Youyu that accomplishes scale production.
Object of the present invention is achieved through the following technical solutions:
A factorial seedling-culturing method of Ma Youyu, comprises the following steps:
