Abstract
The invention relates to a method for cultivating young rapana venosa in rapana venosa artificial breeding. The method is characterized in that firstly, after rapana venosa larvae with the size larger than 1200 micrometers and to be metamorphosed through attachment are collected, then placed in a container containing 10L-12L of a 0.2%-0.3% KCI seawater solution and steeped for 6 hours to 8 hours, so that the rapana venosa larvae is directly metamorphosed without attachment and the young rapana venosa is obtained; secondly, the young rapana venosa is placed in a floating net cage with the length of 5m-6m, the width of 2m-3m and the height of 0.3m-0.4m and made of a polyethylene screen with 60 meshes to 80 meshes, the size of the floating net cage is determined, and the four sides of the floating net cage have the buoyancy force; thirdly, the rapana venosa is fed on oyster paste twice to three times every day, the water level is kept low when feeding is conducted, the floating floating net cage is sunk to the bottom of the pool, bait sunk to the bottom of the floating net cage and attached to a base is eaten by the young metamorphosed rapana venosa, and after feeding is conducted for 3 hours to 4 hours, water is added, the water level rises, the floating net cage is floated, the bottom of the pool is absorbed, and therefore feces and the residual bait remaining on the bottom of the pool are thoroughly cleaned. According to the method for cultivating the young rapana venosa in rapana venosa artificial breeding, the problems that according to a method for indoor rapana venosa breeding, the use ratio of the fed carnivorous oyster paste bait is low and water is prone to pollution are solved and due to the fact that the residual bait and the feces are cleaned in time, water is not polluted, the young rapana venosa lives in water with high quality from beginning to end, the survival rate of the young rapana venosa is high, the breeding amount is improved by over 60%, and the cultivated young rapana venosa is strong.
Description
Technical field
The present invention relates to a kind of method of Rapana venosa artificial breeding, particularly relate to the breeding method of young spiral shell in a kind of Rapana venosa artificial breeding.
Background technology
Rapana venosa (Rapana Venosa) is also known as red spiral shell, and be the peculiar economic shellfish living in coastal zone along the Huanghai Sea and the Bohai Sea, foot is loose especially, and Fresh & Tender in Texture fertile, nutritious, its aquaculture has a extensive future.Because Rapana venosa has cultivation fast growth, the culture-cycle is short, and premunition is strong, and survival rate is high, the advantage of remarkable in economical benefits, the continuous expansion of its aquaculture scale, therefore, also gets more and more to the demand of seed.Because Rapana venosa is carnivorous shellfish, based on carnivorous bait after young spiral shell attached plate, thus it is the bottleneck that the young spiral shell of Rapana venosa is cultivated that the bait after attached plate transforms, therefore, Rapana venosa artificial breeding output of seedling is extremely low, does not reach the level of production, can not meet cultivation unit to the demand of seed, cultivate this technical barrier for the young spiral shell of Rapana venosa, developing a kind of new breeding method is the key solving its difficult problem.At present, after the young spiral shell of Rapana venosa is cultivated and is mainly adopted polyethylene corrugated plate to adhere to as adherance, regularly to throw something and feed shellfish meat gruel, the young spiral shell be attached on corrugated plating is made to be difficult to ingest, bait utilization is lower, very easily cause water quality deterioration at the bottom of pond, cause young spiral shell mortality, the level of production nursery cannot be reached.
Summary of the invention
The object of this invention is to provide the breeding method of young spiral shell in a kind of Rapana venosa artificial breeding, the above-mentioned shortcoming of prior art can be overcome.
The breeding method of young spiral shell in a kind of Rapana venosa artificial breeding, it is characterized in that first namely to want settlement and metamorphosis, after the Rapana venosa young of size more than 1200 microns is collected, put into the container that 10-12 rises the KCI sea water solution containing 2 ‰-3 ‰, soak 6-8 hour, its non-cohesive direct metamorphosis is made to become young spiral shell, then young spiral shell is put into and do growth 5-6 rice with 60-80 order polyethylene screen cloth, wide 2-3 rice, in the floating net cage of high 0.3-0.4 rice, there is buoyancy on four limits of floating net cage, to throw something and feed every day oyster meat gruel 2-3 time, low water level is kept when throwing something and feeding, floating net cage is sunken at the bottom of pond, abnormal young spiral shell is ingested the bait be sunken at the bottom of case and on adherance, bait throwing in terminates 3-4 hour, add water again and flood, floating net cage floats, inhale the end and remove the ight soil and residual bait that remain at the bottom of pond.
Breeding method of the present invention can overcome in Rapana venosa indoor raising of seedling the problem of low, the easy polluted water of carnivorous oyster meat gruel bait utilization of throwing something and feeding, because residual bait ight soil can be removed in time, not polluted water, young spiral shell is in the water quality of high-quality all the time, young spiral shell survival rate is high, output of seedling can improve more than 60%, and the seed of production is healthy and strong.

Accompanying drawing is floating net cage structural representation of the present invention.
Embodiment
The breeding method of young spiral shell in a kind of Rapana venosa artificial breeding, it is characterized in that first namely to want settlement and metamorphosis, after the Rapana venosa young of size more than 1200 microns collects, put into the container that 10-12 rises the KCI sea water solution containing 2 ‰-3 ‰, soak 6-8 hour, its non-cohesive direct metamorphosis is made to become young spiral shell, then young spiral shell is put into and do growth 5-6 rice with 60-80 order polyethylene screen cloth (1), wide 2-3 rice, in the floating net cage (2) of high 0.3-0.4 rice (determining according to nursery pond size), there is buoyancy (3) on four limits of floating net cage (2), to throw something and feed every day oyster meat gruel 2-3 time, low water level is kept when throwing something and feeding, floating net cage (2) is sunken at the bottom of pond, abnormal young spiral shell is ingested the bait be sunken at the bottom of case and on adherance, after bait throwing in terminates 3-4 hour, add water again to improve and cultivate water level, floating net cage (2) is allowed to float, the ight soil remained at the bottom of pond and residual bait is removed at the bottom of timely suction.
Breeding method of the present invention can overcome in Rapana venosa indoor raising of seedling the problem of low, the easy polluted water of carnivorous oyster meat gruel bait utilization of throwing something and feeding, residual bait, ight soil can be removed in time, not polluted water, young spiral shell is in the water quality of high-quality all the time, young spiral shell survival rate is high, output of seedling can improve more than 60%, and the seed of production is healthy and strong.
