Abstract

A flowing water cage type cultivation device for marine juvenile fish relates to a device for cultivating marine juvenile fish. The utility model provides a net cage placed in an indoor cement pit. The cultivation device adopts the technical scheme that a water reservoir and the net cage are adopted, and is characterized in that a water pump is mounted in the water reservoir, wherein, the water outlet pipe of the water pump is connected with the water inlet pipe of the cement pit; a water inlet valve is arranged on the water inlet pipe of the cement pit; an overflow port is formed on the upper edge of a water outlet pipe at the bottom of the cement pit; a water outlet at the lower end of the water outlet pipe of the cement pit is connected with a water drainage pipeline; air stones connected with an air pump through an air pipe are mounted in the cement pit; the net cage consists of a framework and a net cover; a plurality of foam floaters are arranged on the outer edge of the upper end of the net cage, so that the net cage floats in the cement pit; a net mouth is formed at the upper end of the net cage; and the edge of the net mouth is stringed through a nylon rope. After clean sea water is filled in the cement pit, juvenile fish can be put in the net cage in the cement pit to be cultivated.

Description

A kind of seawater juvenile fish flowing water cage breeding arrangement

Technical field:

The utility model relates to the breeding arrangement of breeding seawater juvenile fish.

Background technology

It is an important stage of mariculture that juvenile fish is cultivated, and the fingerling of high-quality can shorten the culture-cycle, quicken capital turnover and increase economic efficiency.The survival rate of fingerling and juvenile fish cultivation in recent years is generally lower.Facility and the device of cultivating at present seawater fish are a lot, and what have utilizes the indoor raising of seedling pool equipment, juvenile fish is directly put into indoor cement pit cultivate; What have utilizes the cage culture device, juvenile fish is placed directly in the breed buoyancy tank on sea to cultivate.But there are a lot of problems in these breeding methods: the one, and the cultivation of indoor cement pit, easy contamination needs frequent soil pick-up, cleans at the bottom of the pool wall pond and changes loaded down with trivial details operation such as water, labour intensity is big, and the fish body is damaged and death easily also, and water quality worsens easily, be subject to the disease influence, cultured output is low; The 2nd, the net cage facility is subject to natural calamity and destroys, and causes the juvenile fish escape, and the culturing area net cage is concentrated, and fish excreta and residual bait cause sea environment seriously polluted, and the juvenile fish disease is more, and health degree is poor, thereby directly influences the quality of fingerling.The 3rd, need treatment in case indivedual juvenile fish is sick, gather and rise that to catch the disease fish cumbersome, usually can only all dispensers treatments in the pond or in net cage, not only increase and cultivate Financial cost, and can produce harmful effect the physique of healthy juvenile fish.Therefore, need that a kind of water quality of design is pure and fresh, high-efficiency environment friendly, the rational seawater juvenile fish of operation breeding arrangement, use this device can obtain the juvenile fish that quality is good, size specification is neat and survival rate is high.

The utility model content

The utility model technical issues that need to address provide a kind of cylinder mould that is placed in the indoor cement pit, can obtain high-quality, high yield, high-servival rate, the breeding arrangement of the seawater juvenile fish that specification is neat.

The technical solution of the utility model adopts cistern, cylinder mould, it is characterized in that being equipped with in the cistern water pump, and the outlet pipe of this water pump is connected to the water inlet pipe of cement pit; The water inlet pipe of cement pit has water intaking valve, and there is gap the outlet pipe upper edge of cement pit bottom, and the delivery port of cement pit outlet pipe lower end connects drainage pipeline; The gas exhausting stone that is connected with air pump by tracheae is housed in the cement pit; Cylinder mould is made of framework and guard, and outer, cylinder mould upper end is provided with a plurality of foam plastic floats, and cylinder mould floats in the cement pit, and the cylinder mould upper end is provided with network interface, and network interface edge string nylon rope is used to tighten up or decontrol network interface; After cement pit injects clean sea water, juvenile fish is put into the cylinder mould of cement pit and cultivate.

Advantage of the present utility model: the one, apparatus structure is simple, and is easily manufactured, and cost is low, is easy to cultivate the unit popularization at aquatic fry growing and juvenile fish; The 2nd, simple to operate, can in the time faster, carry out go-no-go by the juvenile fish to the different size size, alleviated and caught the damage of collection other juvenile fish fish body, and can easily gather the disease fish and treat separately, reduce medicine healthy juvenile fish bad reaction that causes and the pollution that reduces breeding environment.Utilize this device to cultivate the seawater juvenile fish, growth rate is higher than direct cement pit cultures, and the juvenile fish survival rate can reach 87%, far above 45～65% and nursery pond of cage culture culture 32～55%.The juvenile fish quality of being cultivated obviously improves, and juvenile fish is energetic, the body surface not damaged, and specification is neat.The juvenile fish illness rate of compared with prior art being cultivated low 30%.

Embodiment

Below in conjunction with Fig. 1, Fig. 2, Fig. 3 the utility model is further specified:

The utility model is made cylindric framework 19 earlier, 18 one-tenth cylinder moulds of configuration nylon guard 5 on framework, and nylon guard mesh is wide less than the body of juvenile fish.A network interface 21 is left in cylinder mould 5 upper ends, and string has nylon rope 20 around the network interface, in outer, cylinder mould upper end a plurality of foam plastic floats 4 is set, and cylinder mould is floated in the cement pit 3, and the lifting with SEA LEVEL VARIATION.Cylinder mould can adopt diameter 900mm, and high 1150mm can place a plurality of cylinder moulds in each cement pit.Can select the cement pit of deciding different size and the cylinder mould of different size and quantity else according to the quantitative requirement of cultivating juvenile fish 11.When juvenile fish is cultivated, open the water intaking valve 8 of water inlet pipe 2 earlier, the clean sea water 10 that uses water pump 1 will cultivate juvenile fish pumps into cement pit from cistern 9, after water filling reaches waterline 12, the juvenile fish of cultivating is put into cylinder mould by network interface, use the tight network interface 21 of nylon rope 20 strings, in case juvenile fish escapes, daily by untiing nylon rope 20, carry out bait throwing in, the inspection of fish bulk-growth and select operations such as juvenile fish.Place the gas exhausting stone 7 that is connected with air pump by tracheae in the cement pit in addition, to increase oxygen in the water body, delivery port 15 places in the bottom, pond, settle the outlet pipe 14 that matches with delivery port 15 bores, there is gap 13 outlet pipe 14 upper edges, pump into cement pit by water filling port 6 incessantly from cistern along with cultivating the seawater continuous-flow type, via gap, the seawater 17 that flows into outlet pipe enters drainage pipeline 16 at last, thereby makes whole breeding arrangement be in the continuous-flow type state of raising in cages.This juvenile fish flowing water cage breeding arrangement, cost is lower, and is simple to operate, needs the labour less, can easily finish selecting of bait throwing in, different size juvenile fish, fish disease is isolated control and is waited the cultivation operation, and the juvenile fish of being cultivated is energetic, the survival rate height, illness rate is low, the body surface not damaged, and specification is neat.
