Abstract

The invention relates to a method for cultivating the bait of stichopus japonicus selenka in a costal sediment pond. The bait cultivation is carried out from April to May, which comprises that: (1) after the toxicity of the medicine for cleaning the pond fades away, the water in the pond is discharged; the water with the height being 30-50cm is injected again; and 0.075kg/m<2> of organic fertilizer and 0.003 kg/m<2> of chemical fertilizer are put in the pond; (2) when the depth of the inlet water in the pond reaches 80-90cm, demersal diatom is transplanted, 5-10l/mu of algae solution can be transplanted, and carbamide can be put in as per 0-1kg/mu; (3) Ruppia maritime and algae gammarid are transplanted. The Ruppia maritime is uprooted and transplanted integrally as per the quantity of 5-15 plants/m<2>; after the Ruppia maritime is transplanted, the algae gammarid is transplanted as per 1.5-3kg/mu. The beneficial effects of the invention are that not only the raised stichopus japonicus selenka has excellent quality, but also the incidence of diseases is low, the cultivation period is short, the survival rate is improved, therefore the method of the invention has vast promotion prospect.

Description

The bait breeding method of sandy pool Apostichopus japonicus

Technical field

The invention belongs to aquaculture field, specially refer to a kind of bait breeding method of coastal sandy pool Apostichopus japonicus.

Background technology

Stichopus japonicus has very high edible and medical value as sea cucumber a kind of, is the traditional famous and precious marine product of China.Present natural output seldom, because its ecosystem characterization causes its natural distribution and culturing area narrow and small, the past cultivating pool is only built cay bank or the unimpeded sandstone bank of ocean current in, simultaneously, because the narrow of culturing area makes that cultivating pool density is excessive, caused that disease is more in recent years, the output of apostichopus japonicus culture, quality, benefit all significantly glide, and are having a strong impact on the development of apostichopus japonicus culture industry.

Yet, but there are a large amount of argillo arenaceous seashore and beach in China, owing to be subjected to the restriction of natural environmental condition and technical conditions, be " forbidden zone " of holothruian cultures for many years always, break through this " forbidden zone ", carrying out the argillo arenaceous pool holothurian culture, is important directions and content that current holothruian cultures already develop.

Summary of the invention

The objective of the invention is by on littoral argillo arenaceous soil, be based upon the bait breeding method of a kind of sandy pool Apostichopus japonicus based on natural bait of researching and developing on the basis of stichopus japonicus ecological control method of argillo arenaceous pond culture

Its technical scheme is: described bait breeding is to carry out in 4-5 month, it is characterized in that: after comprising that (1) treats that the pond drug toxicity disappears clearly, Jiang Chishui is put dried, receives water 30-50 centimetre again, in the pond, throw in the fertilizer of 0.075 Kilograms Per Square Meter again, the chemical fertilizer of 0.003 Kilograms Per Square Meter; Transplant benthic diatom when (2) water-feeding deep reaches the 80-100 cm height in the pond, the algae liquid of every mu of portable 5-10L, throw by 0-1 kilogram/mu again and remove urea, the transplanting of climing algae in (3) river and algae gammarid, the climing algae in river is uprooped integral transplanting by the quantity of every square metre of 5-15 strain, after the climing algae in river is transplanted, can transplant the algae gammarid by every mu of 1.5-3 kilogram, raise together with the shellfish biology, dark to the pond moisturizing again to 3-4m, in 6-7 month, throw in prawn according to 500-1500 tail/mu.

Described fertilizer is by fermentation.

Effect of the present invention is to provide reliable basic guarantee for developing the breed that a large amount of argillo arenaceous seashores and beach carry out stichopus japonicus, especially adopting ecological bait to transplant raises together with, both save artificial bait and thrown in cost, created the natural ecological environment of apostichopus japonicus culture again.The sea cucumber of being cultured is excellent quality not only, and the incidence of disease is low, and the culture-cycle is short, and survival rate and yield rate all are improved, and have promotion prospect widely.

Embodiment

The present invention illustrates that mainly bait breeding is to carry out in 4-5 month, after comprising that following step (1) treats that the pond drug toxicity disappears clearly, Chi Shui is put dried, again receive 40 centimetres in water, in the pond, throw in again 0.075 Kilograms Per Square Meter by fermentation fertilizer, 0.003 the chemical fertilizer of Kilograms Per Square Meter covers 15 centimetres in pond mud then; Transplant benthic diatom when (2) water-feeding deep reaches 90 cm heights in the pond, help the light of benthic diatom and effect and a large amount of breeding, be convenient to form dominant population, the algae liquid of every mu of portable 8L, throw the piss element by 5 kilograms/mu again, (3) transplanting of climing algae in river and algae gammarid, climing algae is uprooped integral transplanting by the quantity of every square metre 10 strain in the river, after the climing algae in river is transplanted, can transplant the algae gammarid by 2.5 kilograms every mu, in this system, the climing algae in river can be emitted oxygen by photosynthesis, absorb some rich nutritive materials in the water, the algae gammarid is a food with the climing algae in river, the undue growth of the climing algae in control river, prawn is a food with the algae gammarid again simultaneously, but a large amount of diatom of river climing frond table apposition growth, for sea cucumber provides bait, and their fragment also is the high-quality bait of sea cucumber.Raise together with the shellfish biology, meter dark to pond moisturizing to 3.5 again, in 6-7 month, throw in prawn according to 1000 tails/mu.

Claims

1, a kind of bait breeding method of sandy pool Apostichopus japonicus, described bait breeding is to carry out in 4-5 month, it is characterized in that: after comprising that (1) treats that the pond drug toxicity disappears clearly, Chi Shui is put dried, again receive water 30-50 centimetre, in the pond, throw in the fertilizer of 0.075 Kilograms Per Square Meter again, the chemical fertilizer of 0.003 Kilograms Per Square Meter; Transplant benthic diatom when (2) water-feeding deep reaches the 80-100 cm height in the pond, the algae liquid of every mu of portable 5-10L is pressed 0-1 kilogram/mu again and is thrown the piss element; (3) transplanting of climing algae in river and algae gammarid, climing algae is uprooped integral transplanting by the quantity of every square metre of 5-15 strain in the river, after the climing algae in river is transplanted, can transplant the algae gammarid by every mu of 1.5-3 kilogram, raise together with the shellfish biology, dark to the pond moisturizing again to 3-4m, in 6-7 month, throw in prawn according to 500-1500 tail/mu.
