Abstract
The invention belongs to aquiculture animal field, especially one resembles and pulls out freshwater mussel outdoor ponds cultural method.By resemble pull out freshwater mussel seedling outdoor breeding pond adopt Seawater raise together with fish clam mixed cultivation pattern; Wherein Seawater is that turbot culturing pool discharges waste water.Employing the inventive method can meet to resemble pulls out freshwater mussel water Inversion phenomenon and food nutrition demand, overcome harmful animal to attack, improve and resemble the survival rate and growth rate of pulling out freshwater mussel, make resembling of indoor culture pull out freshwater mussel children freshwater mussel, can form in the coastal outdoor of northern China, there is very high economic benefit.
Description
Technical field
The invention belongs to aquiculture animal field, especially one resembles and pulls out freshwater mussel outdoor ponds cultural method.
Background technology
Resemble group freshwater mussel (Panopea abrupta) and originate in U.S. Alaska to California north Coast, belong to Pacific Ocean kind.This shellfish is individual large, and growth is fast, high financial profit, the long 5-8cm of 1 shell in age, heavy 50-100g; The long 10-12cm of 2 shell in age, heavy 200-250g; The long 13-15cm of 3 shell in age, heavy 400-700g.Though resemble and pull out freshwater mussel and originate in North America, its market comsupton mainly concentrates on particularly China and south east asia, Asia.The annual import of China resembles pulls out freshwater mussel millions of kilograms.Resemble the market price of pulling out freshwater mussel in more than ten years in the past maintains in relatively high level always, substantially remain on per kilogram more than 200 yuan, and price constantly rises along with the increase of demand.That pulls out freshwater mussel due to original producton location object fishes for restriction, increases substantially that to resemble the supply of pulling out freshwater mussel more difficult, is subject to the impact of labour cost, charger on air freight and tariff simultaneously, realizes resembling the reduction of pulling out freshwater mussel price very difficult.In the case, the present invention aims to provide a kind of scientific and reasonable cultural method, by providing suitable cultivation place and abundant living body bait, alleviating harmful animal and attacking, improving survival rate, and ensure to resemble the quick growth of pulling out freshwater mussel.
Summary of the invention
The object of the present invention is to provide one to resemble and pull out freshwater mussel outdoor ponds cultural method
For achieving the above object, the technical solution used in the present invention is:
One resembles pulls out freshwater mussel outdoor ponds cultural method, by resemble pull out freshwater mussel seedling outdoor breeding pond adopt Seawater raise together with fish clam mixed cultivation pattern; Wherein Seawater is that Dalian flounder culturing pool discharges waste water.
Outdoor breeding lays gas tube bottom pond, and be filled with Seawater Dalian flounder culturing pool discharge waste water, the breeding box that pulls out freshwater mussel is resembled or raft type cultivating cage is placed in culturing pool by accommodating, in culturing pool, raise together with salmon, Pseudopleuronectes, the flat rockfish of Xu Shi simultaneously, 9-20 DEG C, dissolved oxygen content 6mg/L-8mg/L, salinity be 29-31, realizes fish clam mixed cultivation.
Lay multiple gas tube bottom described culturing pool, be the gas dish of saturated oxygen concentration in installation guarantee culturing pool on a gas tube.
Described culturing pool maritime interior waters media depth is more than 3.5m.
Be provided with multiple hole (1) bottom described breeding box, breeding box inside Down-Up establishes U-shaped fine-structure mesh (2), U-shaped coarse net (3) and cultivation medium (4) (cultivation medium is fine sand) successively; Described elephant is pulled out freshwater mussel seed and is evenly placed in the cultivation medium of breeding box.
Described breeding box there is at least one diameter be 30cm net cage float (5).
The aperture in described hole (1) is 0.8-2.0cm; U-shaped fine-structure mesh (2) is 30-60 order; U-shaped coarse net (3) is aperture 2-6mm; Described cultivation medium is the fine sand of particle diameter 400-500um.
Described Dalian flounder culturing pool discharges waste water circulation water, and winter, water temperature was not less than 9 DEG C, and summer, water temperature was not higher than 20 DEG C, and salinity is 27-31.
Wrap along every layer of available close net etting in plastics disc place at common breeding cage, close net etting mesh is 1cm.
The advantage that the present invention has: adopt satisfied elephant of breeding way of the present invention to pull out the required water Inversion phenomenon of freshwater mussel growth and food nutrition demand, reduce the harmful animal such as gammarid, crab to attack, reduce to resemble and pull out freshwater mussel lethality, improve its output and economic benefit, and then resembling of indoor pond culture can be made to pull out freshwater mussel children freshwater mussel, can form in the coastal outdoor of northern China, make to resemble and pull out freshwater mussel outdoor breeding 1 year individual weight 0.25kg, the output 10-12kg/m of unit are
2.
Accompanying drawing explanation
What Fig. 1 provided for the embodiment of the present invention resembles the structural representation pulling out freshwater mussel outdoor breeding cage.
What Fig. 2 provided for the embodiment of the present invention resembles the structural representation pulling out freshwater mussel outdoor breeding case.
Embodiment
For further illustrating the present invention, illustrate with the following Examples:
Embodiment 1
Outdoor breeding lays gas tube bottom pond, and be filled with Seawater Dalian flounder culturing pool discharge waste water, the breeding box that pulls out freshwater mussel is resembled or raft type cultivating cage is placed in culturing pool by accommodating, in culturing pool, raise together with salmon, Pseudopleuronectes, the flat rockfish of Xu Shi simultaneously, 9-20 DEG C, dissolved oxygen content 6mg/L-8mg/L, salinity be 27-31, realizes fish clam mixed cultivation.
Concrete facility is arranged as follows:
1. facility
Culturing pool adopts light water mud sump, pond area 5 mu, in infundibulate at the bottom of pond, bosom depth of water 4.0m, the most shallow place 2.5m, mean depth of water 3m, laying 18 gas tubes bottom culturing pool, on a gas tube, install a gas dish, is the gas dish of saturated oxygen concentration in guarantee culturing pool.
Breeding cage adopts scallop cultivation cage (as shown in Figure 1), and namely wrap along every layer of available close net etting in plastics disc place at common breeding cage, close net etting mesh is 1cm.Use 6-9 layer scallop cultivation cage according to the depth of water, scallop dish diameter is 29cm, and net footpath is 1cm.
