Description
Technical field
The present invention relates to the mixed feed feeding method of the imitative prawn seed of imitative prawn raising technology, the especially Ha Shi of Ha Shi.
Background technology
Ha Shi imitate prawn (
parapenaeopsis hardwickii) be commonly called as bar shrimp, sliding skin shrimp, the shrimp that chokes, belong to Decapoda, prawn family, Penaeus, is inshore water warm shrimps, is distributed in marine site on the south the southern Yellow Sea of India, Malaysia, Singapore, Japan and China, is grown in 70 meters of offshores with interior seabed.The imitative prawn of Ha Shi is Fresh & Tender in Texture, can, for eating raw, also can be made into dried shrimps, is loved by the people.The imitative prawn of Ha Shi is again coastal principal item of dragging shrimp to produce simultaneously, is one of coastal waters Main economic shrimp.The imitative prawn growth of Ha Shi is fast, breeding period is long, population quantity is large, economic worth is high, Natural Population is not subject to virus infraction, in the situation that current oriental prawn, Penaeus monodon, Penaeus Vannmei virus not yet thoroughly solve, the imitative prawn of Ha Shi is a kind of potential mariculture, propagation kind.
At present, the bait of the imitative prawn artificial breeding of Ha Shi has 2 kinds of series, one is omnidistance biological feed: unicellular alga, fertilized egg-wheel animalcule-artemia larvae of shellfish, although these fresh foods, throw something and feed conveniently, follow-up management is easy, but also there are following shortcomings: cultivate the peak period of fresh food and the agreeable to the taste bait time match of seed rearing and be difficult to, but also be subject to the impact of environmental weather conditions, particularly water rotifer, because the imitative prawn artificial breeding of Ha Shi is in August, this be season temperature higher, outer pool water temperature 30 degree left and right, the extensive culture of rotifera in pond is very difficult, and the wheel animalcule peak duration is very short, often there is such situation: grow seedlings when producing a large amount of needs, wheel animalcule peak is not arrived, can not supply in a large number, produce unwanted time and grow seedlings, bait is cultivated in pond a large amount of wheel animalcules, and the cultivation of fresh food needs certain condition and technology in addition, as: the fertilized egg of shellfish, these have also produced restraining factors to the imitative prawn scale breeding of Ha Shi, another kind is omnidistance manufactured feed: as: yolk, prawn slice, artificial fairy shrimp, sieve by different meshes, throw something and feed to the young of different phase.Although artifical compound feed can be purchased and arrive on market, ample supply and prompt delivery, but manufactured feed easily sinks to the bottom, feeding volume is difficult to control, and the number of times of throwing something and feeding of every day is also more, complex operation, technical requirement are high, and easily because bait deposition too much causes water quality to ruin, the most important is the single disappearance that easily causes certain nutrition of seed of omnidistance manufactured feed nutrition.Above 2 kinds of bait series have shortcoming separately, and all do not relate to the bait of large size seedling seed (young shrimp later stages 10~16 about age in days), the imitative prawn shrimp seedling of Ha Shi of large specification has very strong aggressiveness, if there is no agreeable to the taste bait, shrimp seedling can be baited mutually, mutual residual probability rises, and can reduce the survival rate that seed produces.
