Description
Technical field
It lays eggs method the present invention relates to a kind of bivalve shellfish, and in particular to a kind of suitable imbedded and perched shellfish parent shellfish quickly lays eggs
Method and device belongs to aquaculture field.
Background technique
At present China imbedded and perched shellfish (such as clam, Ruditapes philippinarum, mud blood clam, razor shell, clam, Coelomactra antiquata, razor clam of hanging,
Ba Fei clam etc.) it is many kinds of, yield is maximum, cultivates the supply of seed mainly by seedling rearing in earth ponds and seeding-growth, and by weather, weather
It is affected, it is many that seed supplies uncertain factor, and room heat source generally production level is lower, lays eggs in close shellfish room
Difficulty, emergence rate is low and high production cost is its main cause, and wherein the indoor accelerating of imbedded and perched shellfish parent shellfish is cultivated and oviposition is skill
Art bottleneck, the oviposition technical system that can manually regulate and control at any time without imbedded and perched shellfish parent shellfish so far.
Imbedded and perched shellfish parent shellfish oviposition at present is mainly dried in the shade, heat up stimulus method, and ammonia seawater impregnates and injection oviposition method,
In dry in the shade, heat up stimulus method, laying quality it is good but oviposition effect it is unobvious, ammonia seawater injection and infusion method, inducing effect it is good but
The archiblast of output is poor, and hatching rate is low, is not easy to cultivate, therefore can not obtain a large amount of good fertilized eggs required for artificial breeding,
Large-scale artificial nursery and breeding can not be carried out.
Therefore, there is an urgent need to it is a kind of it is easy to operate, save labor, the side of imbedded and perched shellfish parent shellfish oviposition convenient for management
Method, while ensuring that the ovum quality of output is good, and fast, to meet artificial breeding production needs.
Summary of the invention
It quickly lays eggs method and device the object of the present invention is to provide a kind of suitable imbedded and perched shellfish parent shellfish, it is existing to make up
The deficiency of technology.
One kind is suitable for burying dwelling property bivalve shellfish quickly to lay eggs method, comprising the following steps:
(1) select first reach mature specification bury dwelling property bivalve shellfish as close shellfish, wash, removal is injured and vigor difference
Individual, be put into oviposition device in into culture pond, after dry in the shade processing cultivate；
(2) close shellfish induced spawning opportunity determines: burying the thickness of dwelling property bivalve shellfish sexual gland using post-mortem method in-site measurement, works as sexual gland
Thickness 5-8mm, i.e. preparation induced spawning；
(3) the dwelling property bivalve shellfish parent shellfish of burying for being up to sexual gland maturation is dried in the shade；
(4) the dwelling property bivalve shellfish parent shellfish of burying for completion of drying in the shade in step (3) is put into spawning pond；
(5) charging valve for opening oviposition bottom of device starts to lay eggs to the inflation of dwelling property bivalve shellfish parent shellfish, close shellfish is buried；
(6) it buries dwelling property bivalve shellfish parent shellfish to lay eggs to required fertilized eggs, removes close shellfish and continue to lay eggs, to obtain artificial
Fertilized eggs required for nursery.
Size 4-12cm is selected in the step (1) as close shellfish, it is of different sizes to bury dwelling property bivalve shellfish different size, ratio
Each buries the conduct oviposition specification of the big 1-3cm of biological minimum of dwelling property bivalve shellfish oviposition.
Sexual gland thickness measure is to cut soft body middle position with scalpel in the step (2), then uses vernier caliper
Measure sexual gland maximum gauge.
Close shellfish is dried in the shade 4-8 hours in the step (3), (4), and water temperature of laying eggs in spawning pond is higher by than the water temperature of culture pond
3-5 DEG C, and keep oviposition water temperature constant.
The charging valve that oviposition bottom of device is opened in the step (5) carries out not to the close shellfish of dwelling property bivalve shellfish oviposition is buried
Intermittent inflation, aeration quantity is big, uniform, is subject to and close shellfish is not filled up, fills.
The oviposition device includes the frame body of cuboid, and four side of bottom of the frame body is by tubular structure structure
At the tubular structure is equipped with aeration aperture, and is also connected with gas ducting, and the top of the frame body is a unenclosed construction
Support body, the centre of the support body is an enclosed rectangle structure body, and the inside of the rectangle structure body is equipped with multiple
Parallel crossbeam；The device further includes oviposition frame, which is equipped with purse seine.
