Description
Technical field
The present invention relates to a kind of aquatic products man-made feeds, particularly relate to Trachyostracous mussel floating larvae foundation bait formula.
Background technology
Trachyostracous mussel is the mussel kind that China's economic worth is higher, and compared with Mytilus galloprovincialis, Trachyostracous mussel has the advantages such as nutritious, mouthfeel is good.Mainly be distributed in the bank in China's Huanghai Sea, the Bohai Sea and the East Sea, wherein maximum with the natural resources amount in Zhejiang Province, Shengsi County, Zhoushan is the major production areas of Trachyostracous mussel.For a long time, the seed supply of cultivation needed for Trachyostracous mussel depends on natural waters spatfall, semi always.But in recent years, human development dynamics strengthens day by day, the resource extent of damage is deepened, and natural seeding, wild fry field scope reduces year by year, and cause Trachyostracous mussel natural waters resource to be petered out, Trachyostracous mussel is propagated industry artificially and is a greater impact.Secondly, Trachyostracous mussel natural propagation region, all there are serious problems in the aspects such as seedling, bait, breeding technique, when the envirment factors such as water quality go from bad to worse, Trachyostracous mussel self physique declines, and plants matter and had a strong impact on.At present, Trachyostracous mussel large-scale artificial reproduction technique is never well solved, and nursery quantity is also unstable, and supply falls short of demand to cause seed.In recent years, for obtaining higher economic well-being of workers and staff and the market demand adapting to day by day increase, coastal various places carry out the artificial propagation of Trachyostracous mussel one after another.But the cultivation limitation of Trachyostracous mussel is also very large at present, suppresses the bottleneck mainly seed problem of its extensive aquaculture.The success or not of seed breeding concerns efficient cultivation and the sound development of Trachyostracous mussel.Therefore, bait problem is the basis of seed breeding, and the floating larvae phase is the important period of Trachyostracous mussel seedling maintenance, the foundation bait formulation challenges of period is solved always completely, and the conventional single algae using nothing to fill a prescription is fed and makes nutrition insufficient thus the growth suppressing seed floating larvae.
Micro Algae is single celled planktonic algae, can manufacture organic nutriment voluntarily by photosynthesis, because of a great variety and its floating characteristics become the object of looking for food of zooplankter, is desirable zooplankter bait after nutrition arrangement.Chrysophyceae is also known as golden brown alga, and golden brown is the algae of yellow green or golden brown containing a large amount of beta carotene and xanthic natural colouring matter.Repertory is by the leucosin of β-1,3-glucan (chrysolaminaran) and grease, does not form starch.Cell membrane is generally two-layer being superimposed together as suitcase and forms, have containing silicic acid.Be unicellular travelling kind, acellular wall, has the kind of cell membrane, and its component is mainly pectin.The raw flagellum (three rare) of many tools one or two tops, the isometric or Length discrepancy of flagellum.Storage food is oils and leucosin.Isochrysis galbana cell is exposed, and shape is changeable, but most of ovalize, juvenile cell has a slightly flat dorsal ventral side, and side is seen as oblong or rectangle.Flagellum 2, isometric, born by cell front end, its length is 1 ~ 2 times of cell.Flagellum base portion has vacuole.Have the chromatoplast that one or two sides are raw in cell, its shape and position often change along with the change of cell.There is a nucleus, be usually located at the central authorities of cell.Long 4.4 ~ 7.1 microns of cell, wide 2.7 ~ 4.4 microns, thick 2.4 ~ 3 microns.Can vivaciously move about.Nannochloropsis oculata, cell is spherical, independent or set.Chromatoplast one, light green, side is raw.Eyespot light red orange.In well-grown situation, chromatoplast is very dark, is not easy to observe eyespot.There is no pyrenoids.Have amylum body 1 ~ 3, obviously, side is raw.Cell membrane level is thin, forms space during cell division between cell membrane and cell.Chlorella, spherical or oval.Have the chromatoplast of cup-shaped (nucleoprotein chlorella) or life tabular (avette chlorella) in edge in cell, have the pyrenoids that spherical in the chromatoplast of nucleoprotein chlorella, there are a nucleus in cell central authorities.Cell size is different according to kind, the cell dia of nucleoprotein chlorella 3 ~ 5 microns, and when artificial cultivation, during well-grown, cell can diminish.Diatom is the main bait of fish, shellfish, shrimps particularly its young, and it is together with other plant, forms the primary productivity of ocean.Diatom still forms the sedimental important component part of benthon property.The organic matter that inorganic matter synthesis in seawater self needs by photosynthesis by they.Diatomin comprises chlorophyll a, c1, c2 and carrotene.The unicellular floating characteristics of Micro Algae and nutritious feature make the topmost bait of their become Trachyostracous mussel especially floating larvae phases, fully assume responsibility for the task of the nutrition supply of floating larvae.
Summary of the invention
The object of the invention is to provide that a kind of comprehensive nutrition, attractant are good, feed coefficient is low for prior art, with low cost, cultivate Trachyostracous mussel floating larvae foundation bait formula easily.
The present invention solves the problems of the technologies described above adopted technical scheme: Trachyostracous mussel floating larvae foundation bait is filled a prescription, its containing containing Micro Algae water body number by equal cell density: containing 65 parts to 72 parts, the water body of Isochrysis galbana, 8 parts to 16 parts, water body, 16 parts to 24 parts, the diatomaceous water body containing Nannochloropsis oculata or chlorella or the mixing of the two arbitrary proportion.Water body containing Isochrysis galbana is: the clean seawater mixed with " OA-3011 " arbitrary proportion containing Isochrysis galbana high temperature strain " OA-3011 " or other Isochrysis galbana kinds; Water body containing Nannochloropsis oculata or chlorella or the mixing of the two arbitrary proportion is: the clean seawater of any kind arbitrary proportion mixing in belonging to containing Nannochloropsis oculata or any single kind of Chlorella and mixing thereof or the two; Diatomaceous water body is: the clean seawater of any kind arbitrary proportion mixing containing any single kind of Bacillariophyta or affiliated Bacillariophyta.
Because Trachyostracous mussel floating larvae foundation bait formula of the present invention has following features: Trachyostracous mussel floating larvae 1, can be met and propagate whole nutritional needs under condition artificially; 2, natural feed attractant of filling a prescription is good; 3, the feed coefficient of formula natural feed is low; 4, Trachyostracous mussel floating larvae survival rate is high, illness rate is low; 5, algae kind be easy to get, easily cultivate, with low cost; Natural Micro Algae culture process is simple, thus efficiently solves the pelagic period feed problem that Trachyostracous mussel propagates artificially, and is conducive to environmental protection.
