Abstract
The invention discloses a base bait formula for mytilus crassitesta planktonic larva. The base bait formula comprises the following components according to the parts of a water body containing monodus subterraneus of same cell density: 65-72 parts of water body containing isochrysis galbana parke, 8-16 parts of water body containing nannochloris oculata or chlorella or a mixture of the nannochloris oculata and the chlorella, and 16-24 parts of water body containing diatom. The base bait formula has the advantages of complete nutrition, good luring property, low bait coefficient, low cost and convenience in culture.
Description
Technical field
The present invention relates to a kind of aquatic products man-made feeds, relate in particular to Trachyostracous mussel floating larvae foundation bait formula.
Background technology
Trachyostracous mussel is the mussel kind that China's economic worth is higher, compares with Mytilus galloprovincialis, the advantage such as that Trachyostracous mussel has is 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, the major production areas that Shengsi County, Zhoushan is Trachyostracous mussel.For a long time, the required seed supply of cultivation 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 is dwindled year by year, causes Trachyostracous mussel natural waters resource to be petered out, and 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, and in the situation that the envirment factors such as water quality go from bad to worse, Trachyostracous mussel self physique declines, and germplasm is had a strong impact on.At present, Trachyostracous mussel large-scale artificial reproduction technique is never well solved, and the quantity of growing seedlings 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 adapting to the market demand day by day increasing, coastal various places are carried out the artificial propagation of Trachyostracous mussel one after another.But the cultivation limitation of Trachyostracous mussel is also very large at present, and the bottleneck that suppresses its extensive aquaculture is mainly seed problem.The success or not of seed breeding is concerning 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, foundation bait formula problem is during this time solved always completely, thereby conventional use without the single algae of formula fed the growth that makes the insufficient inhibition of nutrition seed floating larvae.
Micro Algae is single celled planktonic algae, can manufacture voluntarily organic nutriment by photosynthesis, because of a great variety and its floating characteristics becomes the object of looking for food of zooplankter, through being desirable zooplankter bait after nutrition arrangement.Chrysophyceae also claims golden brown alga, and golden brown contains a large amount of beta carotenes and xanthic natural colouring matter and is the algae of yellow green or golden brown.Repertory is by β-1, and the leucosin of 3-glucan (chrysolaminaran) and grease, do not form starch.Cell membrane is generally two-layer being superimposed together as suitcase and forms, and what have contains silicic acid.Be unicellular kind of moving about, acellular wall, has the kind of cell membrane, and its component is mainly pectin.The raw flagellum in many tools one or two top (three rare), flagellum is isometric or not isometric.Storage food is oils and leucosin.Ball 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.2 of flagellums, isometric, by cell front end, born, its length is cell 1 ~ 2 times.Flagellum base portion has vacuole.The chromatoplast that has one or two adnations in cell, its shape and position often change along with the variation 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.One of chromatoplast, light green, adnation.Eyespot light red orange.In well-grown situation, chromatoplast is very dark, is not easy to observe eyespot.There is no pyrenoids.There is 1 ~ 3 of amylum body, obviously, adnation.Cell membrane level is thin, during cell division, between cell membrane and cell, forms space.Chlorella, spherical or oval.In cell, have cup-shaped (nucleoprotein chlorella) or be the chromatoplast that tabular (avette chlorella) given birth at edge, have a spherical pyrenoids in the chromatoplast of nucleoprotein chlorella, there is a nucleus in cell central authorities.Cell size is different according to kind, 3 ~ 5 microns of the cell dias of nucleoprotein chlorella, and the in the situation that of artificial cultivation, during well-grown, cell can diminish.Diatom is the particularly main bait of its young of fish, shellfish, shrimps, and it forms the primary productivity of ocean together with other plant.Diatom still forms the sedimental important component part of benthon property.They synthesize the inorganic matter in seawater by photosynthesis the organic matter self needing.Diatomin comprises chlorophyll a, c1, c2 and carrotene.The unicellular floating characteristics of Micro Algae and nutritious feature make their become Trachyostracous mussel topmost bait of floating larvae phase especially, have fully born the task of the nutrition supply of floating larvae.
Summary of the invention
The object of the invention is to for prior art a kind of comprehensive nutrition is provided, attractant is good, feed coefficient is low, 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 formula, it contains containing Micro Algae water body umber by equal cell density: containing 65 parts to 72 parts, the water body of ball Isochrysis galbana, 8 parts to 16 parts, the water body, 16 parts to 24 parts, the diatomaceous water body that mix containing Nannochloropsis oculata or chlorella or the two arbitrary proportion.Water body containing ball Isochrysis galbana is: contain the clean seawater that ball Isochrysis galbana high temperature strain " OA-3011 " or other ball Isochrysis galbana kinds are mixed with " OA-3011 " arbitrary proportion; Water body containing Nannochloropsis oculata or chlorella or the mixing of the two arbitrary proportion is: contain the clean seawater that in any single kind of Nannochloropsis oculata or Chlorella and mixing thereof or the two genus, any kind arbitrary proportion mixes; Diatomaceous water body is: the clean seawater that any kind arbitrary proportion that contains any single kind of Bacillariophyta or affiliated Bacillariophyta mixes.
Because Trachyostracous mussel floating larvae foundation bait formula of the present invention has following features: 1, can meet Trachyostracous mussel floating larvae and propagate the whole nutritional needs under condition artificially; 2, formula natural feed attractant 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, thereby has effectively solved the pelagic period feed problem that Trachyostracous mussel is propagated artificially, and is conducive to environmental protection.
