Abstract
The invention provides a method for improving survival rate of Arca inflata Reeve in autumn. The method is characterized by comprising the following steps of: firstly, using a vinyl house shrimp pond for reserving scallops or shrimps, wherein the pond is 1.2-1.5m deep, a shielding facility is arranged at the top of the house, and the illumination intensity is less than 500 lux; secondly, using a juvenile mollusk temporary cultivation density vinyl house of which the length is 60m and the width is 15m for temporarily cultivating 4-5 hundred millions of juvenile mollusks; then daily changing water for 1-1.5 ranges during the temporary cultivation period, depositing the sea water for 12 hours without filtering and paying attention to ventilation; and directly transferring the primary juvenile mollusks to the sea for intermediate cultivation till September when the primary juvenile mollusks are longer than 0.25 cm. Via the application of the method, the leisure vinyl house shrimp pond for reserving the scallops or the shrimps is fully used so that the Arca inflata Reeve juvenile mollusks can safely live in the high-temperature season; and the juvenile mollusks are prevented from deaths caused by lack of bait and oxygen which is caused by blocking of the seed bag by floating mud and algae when the juvenile mollusks are too early taken out from the pond and put into the sea, thereby greatly improving the survival rate of the Arca inflata Reeve in autumn after being taken out from the sea and ensuring the high yield and stable yield of manually cultivating the juvenile mollusks at a natural temperature.
Description
Technical field
The present invention relates to the warm naturally offspring seed cultivation method of a kind of stalwart blood clam, particularly a kind of method that improves stalwart blood clam survival rate of seedlings in autumn.
Background technology
The chief blood clam is commonly called as big hair clam, Ark Shell, blood shellfish, belong to Mollusca, lamellibranchiata, blood clam section, it is coastal mainly to be distributed in China, Japan and Korea, the meat flavour deliciousness is the very high large-scale blood clam section shellfish of a kind of economic worth, is one of advantage aquatic products of China's foreign exchange earning, in recent years, it is swift and violent that the chief blood clam is propagated development artificially, but because seed is under-supply, restricted further developing of stalwart blood clam breed.At present, the chief blood clam seed mode of production is that nature incubation seedling and the dual mode of growing seedlings that heats up spring in summer will be arranged, summer, nature incubation seedling was because temperature is higher, bait is difficult for cultivating, during marine in addition intermediate rearing algae etc. easily breeding stop up mesh bag and make seed bait deficiency or death by suffocation, weed survival rate is low; And the seedling cost that heats up spring is very high, adds and scallop artificial breeding time conflict, can not make full use of the resources of production, is subject to the influence of sea area situation at sea during intermediate rearing, produces very unstable.How solving nature incubation seedling stable yields in summer, and improve the survival rate of seedlings in autumn, is to solve the matter of utmost importance that stalwart blood clam scale seed produces.
Summary of the invention
The purpose of this invention is to provide a kind of method that improves stalwart blood clam survival rate of seedlings in autumn, it can satisfy the above-mentioned in-problem specification requirement of solution.
A kind of method that improves stalwart blood clam survival rate of seedlings in autumn, it is characterized in that the idle resources of production after at first making full use of scallop grows seedlings, before arriving, summer high temperature grows seedlings, utilizing scallop or prawn to keep a full stand of seedings then carries out supporting temporarily in the middle of the stalwart blood clam juvenile mollusk with booth shrimp pond, more than the long 0.25cm of juvenile mollusk shell, directly transfer to the sea and carry out intermediate rearing at the beginning of 9 months.Make stalwart blood clam juvenile mollusk ride out summer high temperature season, avoid plunging into the commercial sea too early because of juvenile mollusk goes out the pond, the seedling bag is stopped up by the assorted algae of mud scum, causes juvenile mollusk to lack the bait anoxic, the mortality that causes, thereby the survival rate of seedlings after improving stalwart blood clam seedling greatly and going to sea autumn.
Specific implementation method
At first the idle resources of production after utilizing scallop to grow seedlings brought out stalwart blood clam juvenile mollusk before summer high temperature arrives, and utilized scallop or prawn to keep a full stand of seedings then and carried out supporting temporarily in the middle of the stalwart blood clam juvenile mollusk with booth shrimp pond.Generally at the beginning of 7 months, begin to grow seedlings, when the juvenile mollusk shell is grown 500 microns left and right sides at the beginning of 8 months, carry out booth shrimp pond and support temporarily.Bring canopy shrimp pond temporarily up and require depth of water 1.2-1.5m, long 60m, wide 15m booth can be supported hundred million juvenile mollusks of 4-5 temporarily; Booth shrimp pond vertically is provided with floating stalk, stalk spacing 3m, cursory spacing 2m; Juvenile mollusk adopts 40 order mesh bags to keep a full stand of seedings, 50,000 of the every packed juvenile mollusks of bag of keeping a full stand of seedings of 30cm * 40cm.Keep a full stand of seedings two bags in bag to being, every string is 6 bags, bag spacing 20cm～25cm; Ceiling has the shading facility, and intensity of illumination prevents the assorted a large amount of numerous lifes of algae less than 500lux; Change a water 1-1.5 range every day during supporting temporarily, do not need to filter, and seawater need precipitate 12h, preferably precipitates daytime, changes water night, can increase unicellular alga quantity in the water; The running check juvenile mollusk grows, and notes ventilating; More than the long 0.25cm of juvenile mollusk shell, directly transfer to the sea and carry out intermediate rearing at the beginning of 9 months, can take out bag mid-November and divide a seedling.
By enforcement of the present invention, can make full use of the booth shrimp pond that idle scallop or prawn are kept a full stand of seedings, make stalwart blood clam juvenile mollusk ride out summer high temperature season, avoid plunging into the commercial sea too early because of juvenile mollusk goes out the pond, the seedling bag is stopped up by the assorted algae of mud scum, causes juvenile mollusk to lack bait anoxic, the mortality that causes, thereby the survival rate of seedlings after improving stalwart blood clam seedling greatly and going to sea autumn ensures the stable high yield of warm artificial breeding naturally of stalwart blood clam.
