Abstract
The invention relates to a manual grow seedlings method of Rapana venosa spat, which is characterized by comprising the following steps: firstly selecting parent Rapana venosa; feeding the parent Rapana venosa, changing water, cleaning up the bottom, continuously aerating and keeping the environment dark every day; mating the Rapana venosa 5-6 days later, and removing the parent Rapana venosa after enough oocysts are produced; then hatching the oocysts at a water temperature of 22-24 DEG C for 18-22 days under veliger larvae come out, selecting better ones, and breeding in a pond at a density of 0.3-0.5 per milliliter; changing water and feeding the veliger larvae every day; after 18-20 days, placing the veliger larvae on a polyethylene corrugated plate and a polyethylene collector bag attaching base at a water temperature of 22-24 DEG C; and finally, moving the attached young Rapana venosa having 3-4 whorls after metamorphosis into a purse net of an outdoor pond or a floating net cage, or moving into a floating net cage arranged on the sea, and stripping the Rapana venosa for aquaculture after the Rapana venosa grows to 5mm. The invention solves the problem of low spat survival rate in the indoor manual spat breeding, lowers the production cost and is environment friendly. Besides, the produced spat are robust and grow fast.
Description
Technical field
The present invention relates to the method that a kind of red spiral shell seed produces, particularly relate to the method for 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 its chitin heavily fortified point is thick, carnivorous, and Bivalve is its main food, and growth optimum water temperature is 19-26 ℃.The red spiral shell foot of arteries and veins is loose, Fresh & Tender in Texture fertile, nutritious especially, except that eating raw, can also be processed into the can export trade, and shell also is handicraft and the special material that is used as medicine, and its market prospects are wide.
The red spiral shell of present China is grown seedlings also under test, and is along with the expansion of the scale of breed, more and more to the demand of the red spiral shell seed of arteries and veins; Because red spiral shell is carnivorous shellfish, it is main with carnivorous bait afterwards that red spiral shell attaches plate, and attaching plate bait conversion afterwards is its technical bottleneck; Thereby cause the red spiral shell of the arteries and veins output of seedling of growing seedlings extremely low, and do not reach the level that yielding ability is grown seedlings, satisfied not the demand of unit of culturing to seed; To the red spiral shell seedling growing process of an arteries and veins difficult problem, developing new seedling raising manners is the key that puts the axe in the helve.
Summary of the invention
The method that the purpose of this invention is to provide the red spiral shell artificial breeding of a kind of arteries and veins can overcome the above-mentioned shortcoming of prior art.
The method of the red spiral shell artificial breeding of a kind of arteries and veins is characterized in that at first selecting the red spiral shell kind of arteries and veins shellfish, presses 20-30/m
3Be placed in the nursery pond, plant shellfish and carry out bait throwing in every day, change water, the clear end,, continuous charge is with to keep light dark, and the red spiral shell of arteries and veins carries out mating after 5-6 days, removes kind of a shellfish after producing enough egg capsules; Make egg capsule under 22-24 ℃ of water temperature, hatch veliger through 18-22 days then, egg capsule is treated to be white in color after larva all hatches; Excellent through selecting by the pond cultivation of 0.3-0.5/milliliter density cloth; Change water, bait throwing in every day; Under 22-24 ℃ of water temperature condition, began to throw in polyethylene corrugated plating and polyethylene collector bag adherance through 18-20 days, become the young spiral shell of 3-4 gyration through the veliger settlement and metamorphosis of the 3-5 days red spiral shells of arteries and veins; The adherance that will adhere to young spiral shell at last moves on in the purse seine of outdoor ponds or in the unsteady net cage together; Or be put in the marine unsteady net cage that is provided with; Young spiral shell utilizes pond and benthic diatom and plankton in the sea to grow, and length strips down later on to 5mm, carries out aquaculture.
The invention solves indoors artificial and grow seedlings that bait transforms difficulty, the rotten polluted water of the carnivorous fish of throwing something and feeding, cause that survival rate is low, the problem that output of seedling is low, output of seedling is grown seedlings than indoors artificial and is improved more than 60%.The present invention did not simultaneously need bait throwing in, changes water because of the young spiral shell nurturing period, had reduced production cost, environmental protection, and the seed of production is healthy and strong, and the same with natural seedling, disease is few, and survival rate is high, and growth is fast.
Embodiment
During the method for the red spiral shell artificial breeding of the arteries and veins of embodiment of the present invention, at first in the mating season of the red spiral shell of arteries and veins, select health, no injured, the active red spiral shell of arteries and veins is kind of a shellfish, press 20-30 individual/m
3Be placed in the nursery pond, close shellfish with clam young with mussel serve as that food is is regularly thrown something and fed, change the water and the clear end every day, continuous charge with keep the light dark, the red spiral shell of arteries and veins carries out mate and oviposit after 5-6 days, removes the red spiral shell of arteries and veins after producing enough egg capsules.Next is, egg capsule hatched veliger through 18-22 days and in water, swims under 22-24 ℃ of water temperature, and egg capsule becomes grey black gradually by milk yellow; After treating that larva all hatches, oopod is white in color, and hatching finishes; Excellent through selecting by the cultivation of 0.3-0.5/milliliter density; Change water 1-2 every day, and unit cell algaes such as the flat algae of throwing something and feeding, chrysophyceae 2-3 time are under 22-24 ℃ of water temperature condition; Begin to throw in the polyethylene collector bag of polyethylene corrugated plating adherance and interior dress etting through 18-20 days, become the young spiral shell of 3-4 gyration again through the veliger settlement and metamorphosis of the 3-5 days red spiral shells of arteries and veins.The adherance that will adhere to young spiral shell is at last hung together or is hung in the purse seine of outdoor ponds or in the unsteady net cage; Also can be suspended in the marine unsteady net cage that is provided with; Young spiral shell utilizes pond and in the sea benthic diatom and plankton to grow, and waits to grow to strip down later on to 5mm, sells and carries out aquaculture.
The invention solves polluted waters such as the carnivorous fish gruel of throwing something and feeding in the red spiral shell artificial breeding of arteries and veins; The young spiral shell lethality that causes is high; The problem that output of seedling is low; Output of seedling is grown seedlings than indoors artificial and is improved more than 60%, and the production cost of growing seedlings has been practiced thrift in management work such as the present invention does not simultaneously need bait throwing in the young spiral shell nurturing period, changes water, the clear end.The seed of cultivating is healthy and strong, and the same with natural seedling, disease is few, and survival rate is high, and growth is fast.
