Description

Compound net cage

Technical field

This utility model relates to a kind of aquaculture instrument, specifically a kind of complex aquatic breeding net case.

Background technology

Constantly changing and adjusting along with macroeconomy, fishery resources and external environment condition, China's Ocean Fishery Development is faced with the corss-over constraint of the multiple factors such as market, mechanism, resource, idea, technology.The phenomenon can caught without fish has been arrived in inshore fishing in recent years, and the sea of enclosing in coastal place is made circle and had become as the new normality of sea-farming.Along with the development of science and technology and exchanging of transnational science, cage culture has become as the development trend of aquaculture, and current China net cage for sea farming quickly grows.But major part cage culture is all in coastal waters, due to cultivation behavior do not advise, cultural technique and the backwardness of pattern, the planning lacking scientific unity and management, the various reasons such as pollution of industrial or agricultural sewage, serious pollution is caused to coastal waters water, the phenomenons such as coastal waters cage culture has occurred in that condition of water quality is poor, and cultivation survival rate is low.It is thus desirable to break through existing seawater cage culture pattern, design more scientific and reasonable, be applicable to net cage the most used for aquiculture, to be more reasonably utilized water area resource.

Summary of the invention

This utility model is to improve the above-mentioned deficiency existing for existing cage culture technology, proposition one is applied widely, can utilize Cultivated water to greatest extent, make full use of space, food organisms, improve the utilization rate of bait, improve cultivation survival rate and the compound net cage of culture benefit.

Technical solution of the present utility model is: a kind of compound net cage, it is characterized in that: described composite web case includes outside framework 1, described outside framework 1 is in positive prismatic table shape, with outer etting 2 on outside framework 1, and the going to the bottom at the big end the most thereon of the outside framework 1 of positive prismatic table shape, inner frame 3 it is additionally provided with in outside framework 1, described inner frame 3 is in positive prismatic table shape, with interior etting 4 on inner frame 3, and the upper end of the inner frame 3 of positive prismatic table shape go to the bottom more than it, the upper end of inner frame 3, is arranged on the face at place, the upper end of outside framework 1, and the geometric center at two upper ends overlaps, the outer etting 2 being positioned at 1 time bottom of outside framework is provided with sinker 5, on the top of outside framework 1, also bondage has float, and the mesh diameter of described interior etting 4 is less than the mesh diameter of outer etting 2.

Described sinker 5 is 4, and one square of the formation of the point at these 4 sinker places, and this square overlaps with the geometric center gone to the bottom of outside framework 1.

This utility model compared with the existing technology, has the advantage that

The compound net cage of this kind of version, its simple in construction, design ingenious, rationally distributed, it creatively have employed the structure that two-layer net pen is nestable compared to traditional net cage for sea farming, be therefore applicable to the different depth of water and water environment due to it, can make full use of limited Cultivated water, its scope of application is wider；In it, net cage and outer net cage can cultivate different biologies respectively simultaneously, thus can make full use of the biology in waters and remaining residual bait, thus reach to save the problem of feed cost, and not result in waste and the water pollution of bait；The same biology of different growth phases can also be raised together with by it simultaneously, utilizes internal layer net cage to carry out middle the most foster, can improve cultivation survival rate, reduce aquaculture cost, improve culture benefit；This net cage can create bigger breeding spaces, makes full use of resource and the food resource of breeding water body in limited culturing area, reduces water pollution, provides a comfortable living environment for aquaculture organism, accomplishes the aquaculture model of environmental health.And the framework of this net cage and etting can be dismantled, it is simple to clean and store, and can recycle, reduce aquaculture cost, increase the benefit.It can be said that it has possessed multiple advantage, being particularly suitable for popularization and application in the art, its market prospect is the most wide.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model embodiment.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.nullAs shown in Figure 1: a kind of compound net cage，It includes outside framework 1，Described outside framework 1 is in positive prismatic table shape，Outside framework 1 is accompanied by outer etting 2，And going to the bottom at the big end thereon of the outside framework 1 of this positive prismatic table shape，Inner frame 3 it is additionally provided with in outside framework 1，This inner frame 3 is also in positive prismatic table shape，With interior etting 4 on inner frame 3，And go to the bottom more than it in the upper end of the inner frame 3 of this positive prismatic table shape，The facility of the upper end of inner frame 3 is on the face at the place, the upper end of outside framework 1 simultaneously，The i.e. upper end of inner frame 3, is in the same plane with the upper end of outside framework 1，And the geometric center at the end overlaps in the two，The outer etting 2 of 1 time bottom of foreign language outside framework is additionally provided with sinker 5，Here sinker 5 is 4，And the point at these 4 sinker places forms a square，This square overlaps with the foursquare geometric center formed of going to the bottom of outside framework 1 simultaneously，It is also associated with float on the top of described outside framework 1 simultaneously.

The work process of the compound net cage of this utility model embodiment is as follows: is arranged according to the pattern of " one " word by the compound net cage of the present embodiment and renders in culturing area, and it is fixed on bank at the two ends rope of " one " word, under the common effect of sinker 5 and float, this net cage outside framework 1 is suspended in sea water, four equally distributed sinkers 5 ensure that 1 time bottom of outside framework etting will not under benthic effect on alter, to ensure breeding spaces, the a certain marine organisms of cultivation in the interior etting 4 of inner frame 3, the another kind of marine organisms of cultivation in the outer etting 2 of outside framework 1, breeding process is only thrown something and fed in outside framework 1 bait, the bait of the aquaculture organism in inner frame 3 is the bait or residual bait produced in outside framework 1；Or in the interior etting 4 of inner frame 3, cultivate a certain halobiontic germling, form a centre and support pattern temporarily, this halobiontic adult is cultivated, bait of the most only throwing something and feeding in outside framework 1, it is ensured that the survival rate of aquaculture organism in the outer etting of screen frame frame 1.；

Owing to the mesh aperture of interior etting 4 is relatively small, therefore its interior marine organisms will not move about outside inner frame 3, thus achieve two kinds of (or two specifications) halobiontic complex cultures, and the marine organisms in inner frame 3 can also utilize the outer halobiontic bait residue of inner frame 3 as food source, on the one hand save feeding cost, on the other hand can also make full use of bait, prevent the pollution of the environment.
