Abstract

The utility model discloses a fish culture net rail, comprising a net rail (1) of which the lower end is connected with a base (2) sunk at bottom and the upper end is connected with a floating ball (3) floating on water, wherein the lower part of the base (2) is provided with a drain hole (2a) communicating the water regions at two sides of the net rail (1). The fish culture net rail is suitable for culturing fish in reservoir whose water level changes annually, to prevent culture from being affected by the increase and decrease of water level, and has sealed net bottom to avoid fish escape, has high resistance to the impact of water flow, wind and wave, has lower cost than dam construction, and can utilize the coastwise vegetal cover along water level fluctuating zone to improve culture yield and quality.

Description

The wire net of breeding fish

Technical field

The utility model belongs to a kind of wire net of breeding fish, and specifically, is a kind of reservoir fish farming in cove wire net.

Background technology

At present, the mode that breed waters formed falling zone interception water body is breeded fish has two kinds, and the one, wire net, the 2nd, the dam blocks.This dual mode is dark at water body, use in the big waters of water level week annual variation, the insoluble problem of bringing of breeding fish, its reason is that net blocks the block of breeding fish and must be placed under the lowest water level in gulf, storehouse, falling zone, can avoid the situation that do not have water to breed fish when low water level, and be located under the low water level elevation, again because of in the phase depth of water net height of rising, the net bottom bad sealing causes escaping the very risky of fish accident generation, and the too high very difficult wind wave resistance water impact of blocking, and the risk that the broken fish of generation net escapes is more not little; Block engineering and breed fish and build the dam, quantities is big, and the construction cost height can not utilize the vegetation of falling zone bank to improve cultured output and quality.

The utility model content

It is a kind of that technical problem to be solved in the utility model is to provide, the novel hurdle net that can breed fish on a large scale in reservoir Ku Wan falling zone, it is a kind of wire net of breeding fish that has pedestal, can rise or water-break is between the different water levels and normally breeds fish at reservoir, the net bottom sealing is tight, wind wave resistance water impact performance is good, safe and reliable.

The technical solution of the utility model is as follows: a kind of wire net of breeding fish, and described wire net lower end is connected with the pedestal that sinks under water, and pedestal is similar to dam, and this wire net upper end is connected with the ball float that floats on the surface.Its pedestal can wind wave resistance wash away with non-leakage, can hold back to guarantee fish normally ingest growth needed water body space and good water quality environment when water level depression, makes breeding production continue to carry out.

The wire net height is decided with the height of falling zone peak level according to the pedestal top, the function of wire net is that the fish that the waters, district puts in a suitable place to breed that prevent to block run away in the outer water body of block, the outer predacious fish of also anti-block is swum the fry and fingerling of eating in the interior breed waters of block, have in addition and the inside and outside water body of block freely exchange by mesh smoothly flow, thereby keep the good of interior cultivation water environment of blocking.

In the phase of rising, by pedestal and net associating culture zone, the formed dam of block, water enters from the block on the dam outside the dam, the inside and outside water body in dam freely exchanges, breeding water body increases, add the littoral growing plants in falling zone and provide the good ecotope of ingesting, grow, cultured output, product quality are improved for culturing object;

The water-break phase, the dam intercepts water and can guarantee to culture the object growth of normally ingesting in the body culture zone, the while vegetation of falling zone bank utilized by its next one cycle of rising.

This novel wire net is cultured, and net blocks and is in the terrestrial facies state and separates with the outer big water surface in dam when low water level, and the dam when wide dam net is united culture zone and low water level when so just having formed high water level intercepts water the ecologic breeding new frame of face culture zone.

The said base bottom has the osculum that can be communicated with waters, net both sides, hurdle.In some special circumstances, the water of the face culture zone of the dam can being intercepted water is discharged, is drained.

The said base cross section is that trapezoidal planform to dam is similar.

The above wire net is the fishnet that fishnet or band block grid.Described hurdle net is at least one deck fishnet and constitutes.

Beneficial effect: the utility model is applicable to different water levels, and water level goes up and descend unaffected to aquaculture, and net bottom seals the tight fish accident generation that can not cause escaping; Good anti-current, stormy waves impact property are arranged; Relatively to block engineering cost cheap with repairing the dam, can also utilize the vegetation of falling zone bank to improve cultured output and quality.

Description of drawings

Fig. 2 is user mode figure of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, the utility model wire net of breeding fish is made up of hurdle net 1, pedestal 2 and ball float 3, and net 1 lower end, described hurdle is connected with the pedestal 2 that sinks under water, and these pedestal 2 cross sections are that trapezoidal planform to dam is similar.This hurdle net 1 upper end is connected with the ball float 3 that floats on the surface.Described pedestal 2 bottoms have the osculum 2a that can be communicated with waters, hurdle net 1 both sides.The hurdle net is two kinds of forms of fishnet that fishnet or band block grid.Described hurdle net is at least one deck fishnet and constitutes.

As shown in Figure 2, the wire net of breeding fish is placed on crook, reservoir storehouse, the breed fish waters on wire net the right is dam and net associating culture zone, the formed dam of block, the net associating culture zone, dam that is positioned at pedestal 2 tops is a falling zone vegetation region 4, and the net associating culture zone, dam that is positioned at hurdle net 1 below is that the dam carries aquifer cultivation district 5; Water-break is during the phase, and water level is shifted the hurdle net onto below 1, and the plant that falling zone vegetation region 4 grows when the phase arriving water level that rises rose more than pedestal 2 tops, can utilize the vegetation of falling zone bank to improve cultured output and quality.

Claims

1, a kind of wire net of breeding fish comprises hurdle net (1), it is characterized in that: described hurdle net (1) lower end is connected with the pedestal (2) that sinks under water, and this hurdle net (1) upper end is connected with the ball float (3) that floats on the surface.

2, the wire net of breeding fish according to claim 1 is characterized in that: described pedestal (2) bottom has the osculum (2a) that can be communicated with hurdle net (1) waters, both sides.
