Description

A kind of cultural method and breed place of lacking octopus

Technical field

The present invention relates to aquaculture technology, be specifically related to a kind of cultural method and breed place of lacking octopus.

Background technology

Short octopus, latin name: Octopus ocellatus English name: Octopus variabilis, be temperate zone property mollusk, growing environment is had relatively high expectations, suitable water temperature is 10-23 ℃, suitable seawater salt content is 12-20 ‰, and the environment that water temperature is lower than 7 ℃ or low salinity easily causes short octopus death.

Short octopus meat flavour deliciousness can be eaten raw, also can shine into dried fish, and can be used as medicine, and has the effect of benefiting qi and nourishing blood, convergence myogenic, is the invigorant of women's qi-restoratives in postpartum, lactogenesis, lactagogue.Domestic demand to short octopus increases day by day, and also there is very big import demand in countries such as Japan and Italy to short octopus, and lacks octopus at present fishing for, and that is that all right is ripe for artificial culture technology.

In the prior art, lack the cage culture of octopus in many natural water areas in the quiet bay of wave, because short octopus is to the having relatively high expectations of habitat, and in natural water area, water body environments such as the temperature of seawater, salt content can be subjected to ocean current and climatic influences, and can't manually adjust; Marine organisms or harsh weather are also easily taken place simultaneously cause net cage to destroy, the situation that short octopus is escaped, above-mentioned reason make the short octopus cage culture survival rate at natural water area that 50-70% only be arranged, and culture benefit is lower.And the cage culture of natural water area, also give short octopus fish for and transportation is made troubles.

Summary of the invention

In view of this, in order to address the above problem, the invention provides a kind of cultural method of lacking octopus, the short octopus of control is perched the temperature and the salt content of water body, improves the survival rate that short octopus is cultured, and obtains higher benefit.

A kind of short octopus cultural method is raised in holding pond, also is provided with the loop temperature-control pond, and water circle device flows into holding pond with the water in the loop temperature-control pond by register, and the control water temperature is 12-18 ℃; The salt content of control water is 12-20 ‰.

Further, the Chi Shui to holding pond carries out the oxygenation operation;

Further, short octopus is contained in to bring up in the box and raises, and each is brought up in the box and adorns a short octopus; Bringing up box is suspended on below the water surface by ropy; Also can entangle and be suspended on the water surface below by netted bagging one or more raising boxes;

Another object of the present invention provides a kind of breed place of lacking octopus, comprises holding pond and temperature-controlling system; Described temperature-controlling system is made up of loop temperature-control pond, register and water circle device; Water circle device flows into holding pond after the water in the loop temperature-control pond is regulated temperature by register.

Further, also be provided with aeration system, oxygenation in the water of the pond of holding pond;

Further, the holding pond area is a 1-3 mu, the dark 1-1.2m in pond;

Further, the holding pond top is provided with support, also has ropy, and an end is fixed on the support, brings up box with one or one group and hangs in the water; One group is brought up box is at least 2 raising boxes that netted bagging entangles;

Further, bringing up box is the cylindrical shape of hollow, is made up of loam cake and box body, brings up box box wall and is provided with through hole, and the diameter of described through hole is 0.3-1mm;

Short octopus cultural method of the present invention and breed place have following beneficial effect: lack octopus and culture in artificial waters, can adjust water temperature, salinity easily, not influenced by natural causes such as ocean current, weather; Be provided with temperature-controlling system, water temperature is controlled at 12-18 ℃, salt content is controlled at 12-20 ‰, and short octopus is grown in the optimum environment, can improve the growth rate of short octopus, reduces the possibility that disease takes place, and cultures survival rate and reaches more than 90%; Chi Shui to holding pond carries out the oxygenation operation; Make enriched oxygen content in the water body, short octopus growing environment further improves, and improves output; Because internecine situation easily takes place in short octopus disposition ferociousness, therefore use and bring up box short octopus isolated rearing, can further improve the survival rate that short octopus is cultured; The holding pond area is too small, and water body easily worsens, and the availability of unit are is not high, and area is excessive, and then control brings difficulty to temperature, and area 1-3 mu can obtain optimum efficiency.

Description of drawings

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing shows the schematic diagram of the short octopus raising box according to the present invention.

Embodiment

Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.

Embodiment 1

Culture the place and be provided with 1 holding pond and 1 loop temperature-control pond, 3 mu of holding pond areas, the degree of depth is 1m, the salt content of water is 18 ‰; The loop temperature-control pool volume is about 1500m3, also be provided with register and water circle device, water circle device can adopt one-way pump, its oral siphon is arranged at loop temperature-control pond one end, outlet pipe connects the water inlet pipe of register, and water flows into holding pond through after the adjustment, and register can adopt existing breeding water thermosistor, the outlet pipe of thermosistor inserts holding pond, and register is controlled at the holding pond water temperature about 15 ℃.
