Abstract
A method of artificial breeding for ark shells, which includes cultivating unicellular algae first, then breeding, sampling and inspecting parent calms gonads of ark shells in the sea, capturing and transporting parent calms, breeding species shells temporarily in seeding room interiorly; spawning and hatching parent calms; selecting and breeding larvae, cultivating larvae, changing water once a day, scattering bait 30,000-100,000/ml single cells every day; scattering cultch when the body length of larvae is 230 micrometers, changing water totally every day, moving larvae to the middle of the sea or shrimp tank to breed temporarily when the shells of them are 0.7-1.2mm; beating platform raft firstly as temporary breeding, the direction of which and flow direction being almost vertical; temporary breeding management, tying one hanging at intervals of 0.6-1.0m on every platform raft, 6-10 bags on every hanging, 5,000-15,000 juveniles shellfishes in every bag, arranging platform raft, promising the safety of platform raft, scattering on the bottom of the sea or cultivating in the shrimp tank when juveniles shellfishes grow up above 5mm. The advantage of the method can realize artificial breeding, short time of breeding, cultivation in the shrimp tank, bottom sowing in the sea and resume the population advantage, low-cast, quick results and great benefit.
Description
Background technology
Blood clam is commonly called as blood clam, is coastal bivalve intertidal shellfish.Its delicious meat, be rich in haemoglobin and cobalamin, the effect that having enriches blood is good for the stomach, supply falls short of demand in market, is subjected to liking of numerous people deeply.The blood clam seed mainly is by its natural propagation, and output fell sharply, faced total crop failure recent years, and artificial breeding is still blank at present.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, provide a kind of and realize that indoors artificial is grown seedlings and seedling raise period short, it is pool cultivated both can to have carried out shrimp, can carry out again broadcasting the increase resource at the bottom of the sea area, can recover the population advantage, cost is low, the artificial raise seedling method of instant effect, blood clam that benefit is big.
Technical solution of the present invention is:
At first, carry out the cultivation of unicellular alga, the beginning of March begins to cultivate single-cell algae, and the kind that is adopted has Chaetoceros, Dicrateria inornata, Isochrysis galbana, chlorella, tower born of the same parents algae, requires to buy the algae kind of new separation, ensuring the quality of products, and cultivates in the one-level bottle;
Grow seedlings, carry out blood clam parent shellfish sexual gland inspection to marine 20～August 2 June, carried out once in per 3～7 days, takes a sample 1～2 kilogram at every turn; The parent shellfish is adopted and catches and transport, and when the fast maturation of blood clam parent shellfish gonad development, requires to adopt nearby to catch, and adopts in the place that does not have ship to pollute and catches; Carry out kind of shellfish in the pond of indoor rearing seedling room injection seawater and support temporarily, plant shellfish and support 30～80/m of density temporarily
3, the depth of water 80～150cm is placed in the net basket and supports temporarily, and every day, full dose was changed water once; The hatching of laying eggs of parent shellfish, the density of laying eggs is controlled at 20～50/ml, if density height then divide the pond; The larva seed selection, when larvae development to D shape larva, seed selection after 2 hours, water-head is controlled within the 0.5m during seed selection; Larval culture, cultivating density in the pond is preceding 10～12/ml in shell top, shell top phase 6～8/ml, shell top later stage 4～5/ml, density is difficult for too high, changes water every day once, 3～100,000 unicellular/ml of daily ration, feeding quantity every day; When the larva body reaches 230 microns, throw in adherance, adhering to base unit weight is 1～4kg/m
3Management after adhering to is adhered to back food ration every day and is increased to 10～300,000 unicellular/ml gradually, and every day, full dose was changed water once, moves on in the middle of the sea area when the shell long size reaches 0.7～1.2mm or support temporarily in the shrimp pond;
Carry out in the middle of the young shellfish of blood clam sea area again or support temporarily in the shrimp pond, make the platform raft earlier, before June 20, finished, selects sea area or shrimp pond pollution-free, that trend is unimpeded, stormy waves is less, depth of water 5m is above, the stalk length 80～150m that restricts, platform raft direction is bordering on vertical with the flow direction; Support temporarily management: each raft hangs every 0.6～1.0m watchman's wooden clapper one, whenever hangs on the 6-10 bag, adorns 5000～15000 young shellfishes in every bag, every day, the brush bag was 1～2 time, cleaning mud, arrangement platform raft, changed mesh bag in 10～15 days one time, carry out the branch seedling if seedling is close when changing bag, mesh bag order number is: 60 orders → 40 orders or 30 orders → 20 orders, put the platform raft every day in order, the mesh bag that stirs is together untied, guarantee platform raft safety, reach more than the 5mm to working as young shell, carry out broadcasting at the bottom of the sea area or or shrimp pool cultivated.
Beneficial effect of the present invention:
Can realize that indoors artificial is grown seedlings and seedling raise period short, can heat up in advance grows seedlings emerges Zao than natural seed.It is pool cultivated both can to have carried out shrimp, can carry out again broadcasting the increase resource at the bottom of the sea area, can recover the population advantage, and cost is low, instant effect, benefit are big, and the seed of current year's production just can be sold, and two can carry out broadcasting the increase resource at the bottom of the sea area, recovers the population advantage.
