Abstract

A method for cultivating juvenile rapana venosa in artificial breeding comprises the following steps: cultivating the juvenile rapana venosa attached on all the metamorphosis rapana venosa according to the density of 100,000-150,000 in each square meter; then selecting the mature oyster or the oyster to mature, artificially anatomising the oyster, identifying the sex through microscopic examination, respectively obtaining sperm and ovum, and artificially inseminating to obtain germ cells; later uniformly putting the obtained germ cells in a cultivating pond in which the juvenile rapana venosa is attached, wherein the density of the germ cells is 5 to 6 in each millilitre; periodically inflating air and stirring so that the germ cells can be uniformly settled on a polyethylene corrugated plate so that the attached juvenile rapana venosa can eat the germ cells attached on the plate; putting the plate and the frame attached with the juvenile rapana venosa upside down after 10 to 12 hours for one time, later moving in a new pond after 1-2 days, putting the germ cells, and after growing to 3-4 mm, putting small fresh low-value shellfish. The cultivating method of the invention can solve the problem that the survival rate of the artificial breeding of the indoor rapana venosa is low, which is caused by that the bait is difficulty to switch and the fed predatory minced fillet pollutes the water, and can solve the problem that the seedling quantity is low.

Description

The breeding method of young spiral shell in the red spiral shell artificial breeding of a kind of arteries and veins
Technical field
The present invention relates to the method for the red spiral shell artificial breeding of a kind of arteries and veins, particularly relate to the breeding method of young spiral shell in the red spiral shell artificial breeding of a kind of arteries and veins.
Background technology
The red spiral shell of arteries and veins (Rapana Venosa) claim red spiral shell again, is the peculiar economic shellfish of living in yellow Bohai Sea bank, and foot is loose especially, and Fresh & Tender in Texture fertile, nutritious, its aquaculture has a extensive future.Because the red spiral shell of arteries and veins has the breed fast growth, the culture-cycle is short, and premunition is strong; Survival rate is high, the advantage of remarkable in economical benefits, the continuous expansion of its aquaculture scale; Therefore, also more and more to the demand of seed, the red spiral shell of China's arteries and veins is grown seedlings also at the experimental stage at present.Be that it is main that abalone attaches after the plate with benthic diatom because the red spiral shell of arteries and veins is the difference of carnivorous shellfish and abalone fry-rearing, and young spiral shell to attach after the plate be to be main with carnivorous bait; Thereby the bait conversion that attaches after the plate is the bottleneck that the young spiral shell of the red spiral shell of arteries and veins is cultivated; It can cause the red spiral shell of the arteries and veins output of seedling of growing seedlings extremely low, does not reach productive level, has satisfied not the demand of unit to seed of culturing; Cultivate this technical barrier to the young spiral shell of the red spiral shell of arteries and veins, developing a kind of new breeding method is the key that puts the axe in the helve.At present, utilizing the oyster juvenile mollusk that adheres to and young shellfish etc. as bait though developed, need oyster juvenile mollusk and young shellfish that one-month period in advance cultivates, is to cultivate another kind of seed through a kind of seed rearing, and it is longer that juvenile mollusk is cultivated the time, and expense is higher.
Summary of the invention
The breeding method that the purpose of this invention is to provide young spiral shell in the red spiral shell artificial breeding of a kind of arteries and veins can overcome the above-mentioned shortcoming of prior art.
The breeding method of young spiral shell in the red spiral shell artificial breeding of a kind of arteries and veins is characterized in that the first young spiral shell of the red spiral shell of arteries and veins that whole settlement and metamorphosis are become is by ten thousand/m of 10-15 2Density cloth pond cultivate, then selective maturation be about to ripe oyster, with this oyster artificially dissect, microscopy distinguishes female, male; Obtain sperm, ovum respectively, artificial insemination obtains fertilized egg, gained fertilized egg is dropped in the cultivation pond of adhering to young spiral shell equably again; Fertilized egg density is 5-6/ml, regularly inflates and stirs, and fertilized egg is sunken on the polyethylene corrugated plating equably; The young spiral shell that adheres to is ingested and is sunken to the fertilized egg on the lamina affixad, puts upside down lamina affixad and frame with young spiral shell 1 time after 10-12 hour again, moves into new pond after 1-2 days and drops into fertilized egg again; Long behind 3-4mm, change and throw fresh and alive small-sized low value shellfish.
Breeding method of the present invention can overcome the red spiral shell indoors artificial of arteries and veins grows seedlings because of the survival rate that bait transforms difficulty, the rotten polluted water of the carnivorous fish of throwing something and feeding causes is low, and the problem that output of seedling is low is because the fertilized egg of oyster is a demersal egg; Be that embryo, the yolk content of living enriches, need do not change water, food quality is good; Output of seedling can improve more than 80%; Also practiced thrift production cost simultaneously, the seed of production is healthy and strong, environmental protection.
Embodiment
The breeding method of young spiral shell in the red spiral shell artificial breeding of arteries and veins of the present invention is characterized in that the first young spiral shell of the red spiral shell of arteries and veins that whole settlement and metamorphosis are become is by ten thousand/m of 10-15 2Density cloth pond cultivate, then selective maturation be about to ripe oyster, with this oyster artificially dissect, microscopy distinguishes female, male; Obtain sperm, ovum respectively, artificial insemination obtains fertilized egg, gained fertilized egg is dropped in the cultivation pond of adhering to young spiral shell equably again; Fertilized egg density is 5-6/ml, regularly inflates and stirs, and fertilized egg is sunken on the polyethylene corrugated plating equably; The young spiral shell that adheres to is ingested and is sunken to the fertilized egg on the lamina affixad, puts upside down lamina affixad and frame with young spiral shell 1 time after 10-12 hour again, moves into new pond after 1-2 days and drops into fertilized egg again; Long behind 3-4mm, change and throw fresh and alive small-sized low value shellfish.
The present invention can overcome indoors artificial and grow seedlings because of the survival rate that bait transforms difficulty, the rotten polluted water of the carnivorous fish of throwing something and feeding causes is low the problem that output of seedling is low.Because the fertilized egg of oyster is a demersal egg, the embryo who lives, yolk content is abundant, therefore, need not change water, has practiced thrift production cost, and the seed that produces is healthy and strong, and survival rate is high, fast growth.
Embodiment
The young spiral shell of the red spiral shell of arteries and veins that earlier whole settlement and metamorphosis is become during enforcement is pressed 120,000/m 2Density cloth pond cultivate, then selective maturation be about to ripe oyster, dissect this oyster is artificial; Microscopy is distinguished female shellfish, male shellfish, obtains to get sperm, ovum respectively, and artificial insemination obtains fertilized egg then; Acquisition fertilized egg is dropped in the cultivation pond of adhering to young spiral shell equably, fertilized egg density is 5/ml again, inflation in per 2 hours 1 time; Each inflation 2 hours also is furnished with stirring, because the fertilized egg of oyster is a demersal egg, fertilized egg can be sunken on the polyethylene corrugated plating equably; The young spiral shell that adheres to is ingested and is sunken to the fertilized egg on the lamina affixad, puts upside down lamina affixad and frame with young spiral shell 1 time after 10 hours again, drops into fertilized egg again behind the new pond of immigration after 2 days; Through cultivation in 1 month, long behind 3mm, change and throw fresh and alive small-sized low value shellfish.
