Abstract
The invention discloses an attachment for improving the survival rate of juvenile mytilus coruscuses and a using method thereof, and relates to artificial shellfish breeding in the field of aquaculture. The attachment is formed by putting a bamboo fiber-woven mesh into a special pressure cooker, cooking for 1 hour by using tea water, fishing out, and drying in the sunlight, wherein the mesh is 60-mesh, has the width of 60cm and the length of 100cm; pendants with proper weights are hung on the length side of the mesh. The using method of the attachment comprises the following steps: selecting creeping larvae, collecting the growing creeping larvae, attaching and controlling an attachment condition. The attachment improves the attaching survival rate and the attaching density so as to increase the metamorphosis rate of the larvae, reduce the breeding cost of the mytilus coruscuses and promote the development of the breeding industry of the mytilus coruscuses.
Description
Technical field
The present invention relates to the shellfish artificial cultivation of aquaculture field, particularly a kind of attachment and using method improving Trachyostracous mussel juvenile mollusk survival rate.
Background technology
Mussel is under the jurisdiction of Mollusca, lamellibranchiata, mussel order, Mytilidae, and mussel belongs to, and be marine products bivalve shellfishs, paddy claims blue or green mouth, Hai Hong, and its dried product claims mussel, has very high nutritive value.The edible mussel that coastal area of china produces mainly contains Mytilus galloprovincialis, Trachyostracous mussel and Perna viridis etc.Trachyostracous mussel is one of important economic shellfish of China, due to artificially excessively adopt catch and the protection of propagation ineffective, sea area nature Trachyostracous mussel resource exhaustion, nursery difficulty is large, and cultivation seed is difficult to solution in enormous quantities, inhibits the extensive development that Trachyostracous mussel cultivates.Become the annual price of shellfish to increase with 20% in recent years, economic worth is high, current price per jin about 8 yuan.Trachyostracous mussel byssus is attached on attached foster thing and lives, and utilizes the gill to filter food.The developmental stage of Trachyostracous mussel comprises the stages such as fertilized egg, morula, blastula stage, trochophore, D shape larva, shell top larva, Creeping larva, and before becoming attachment adult, have a floating larvae stage, larva is attached in matrix, and metamorphosis becomes juvenile mollusk.Larva attachment is beneficial to by throwing in various types of Seedling culturing device in the floating larvae stage at present in artificial breeding process, the Seedling culturing device of the material such as usual employing " transparent PP corrugated tile ", " palm rope ", " straw rope ", " polyethylene mesh sheet " carries out screening and throws in, attachment survival rate is only below 30%, and so low settlement and metamorphosis rate seriously constrains the development of Trachyostracous mussel aquaculture.
Summary of the invention
The invention provides a kind of attachment and the using method that improve Trachyostracous mussel juvenile mollusk survival rate, overcome and in artificial breeding process, usually adopt " transparent PP corrugated tile " at present, " palm rope ", " straw rope ", the Seedling culturing device of materials such as " polyethylene mesh sheet " carries out screening and throws in, attachment survival rate is only below 30%, so low settlement and metamorphosis rate seriously constrains the defect of the development of Trachyostracous mussel aquaculture, provide one and can improve Trachyostracous mussel juvenile mollusk survival rate, to improve larval metamorphosis rate, save Trachyostracous mussel aquaculture cost, promote attachment and the using method of the development of Trachyostracous mussel aquaculture.
The present invention is achieved through the following technical solutions: a kind of attachment improving Trachyostracous mussel juvenile mollusk survival rate, described attachment is the mesh sheet be woven into by bamboo fibre, woven mesh sheet is placed in special high-pressure pot after using Aqua Folium Camelliae sinensis boiling 1h, picks up and dry; The mesh of described mesh sheet is 60 orders, and described mesh sheet is wide is 60cm, length is 100cm; Side, described netting length place hangs with and mesh sheet can be made to sink the weight of suitable weight.
The using method of the attachment of above-mentioned raising Trachyostracous mussel juvenile mollusk survival rate, comprises the steps:
(1) Creeping larva is chosen: choose the Creeping larva that size is 300-320 micron, directly sinks down at the bottom of attachment pond, and attachment pond water temperature is 18 ~ 20 DEG C, through the growth of 8 ~ 10d, is rinsed the Creeping larva of growth in the mesh bag of delivery port by draining;
(2) Creeping larva of growth is collected: collected by the Creeping larva grown in mesh bag;
(3) adhere to: the great Chi putting into clear water after attachment being thrown away sterilization, makes it naturally be erected in pond, and the Creeping larva of growth step (2) gathered is splashed in pond, makes them naturally be attached on attachment;
(4) condition of adhering to controls: during attachment 30-50h, and cover with black shade net above pond, light transmittance controls below 20%, water temperature 20 ~ 22 DEG C, then at top, pond erection blue led fluorescent tube, opens carry out light stimulation at night.
Compared with prior art, the present invention has following outstanding advantages and effect: the present invention innovates and adopts the mesh sheet that is woven into of bamboo fibre as attachment, and mesh sheet is aseptic has fragranced again by making after scientific disposal, very suitable Trachyostracous mussel attachment.By constantly groping the best using method defining attachment, thus improve attachment survival rate and attachment density, on average every square metre of attachment juvenile mollusk seed is about 800,000, maximum every square metre of adhesion amount reaches more than 1,000,000, bring up to more than 60% than the spatfall method attachment survival rate generally adopted at present, attachment density brings up to more than 50%; By this method proposing rational spatfall base, spatfall method and spatfall base release time, substantially increase survival rate and the attachment density of attachment juvenile mollusk.
