Abstract
The utility model relates to an American shad breeding pond which comprises a breeding pond body, a supporting framework, a side wall anti-collision net and a bottom anti-collision net. The supporting framework is arranged in the breeding pond body. The cylinder-shaped side wall anti-collision net is arranged on the supporting framework. The bottom end portion of the side wall anti-collision net is connected with the bottom anti-collision net. The American shad breeding pond avoids the phenomena, to the greatest extent, that American shads collide with the pond wall repeatedly to cause death of a large number of American shads due to the fact that the American shads are impatient when the American shads enter an ordinary cement breeding pond at the first time, and also avoids the problem that the shads are startled when workers collect germ cells generated through copulation.
Description
Technical field
The utility model relates to a kind of American shad and cultures the pond, and the utility model belongs to technical field of aquaculture.
Background technology
Before and after the seventies in 20th century, the Changjiang river hilsa herring annual production once reached more than 1000 ton, but after this because water conservancy construction has cut off laying eggs of hilsa herring and feeding migration passage, added that excessive amount of fishing and water environment pollute, and the hilsa herring natural resources sharply reduce.Only about 500 kilograms, the Changjiang river water system hilsa herring resource almost disappeares in Yangtze river basin hilsa herring annual production at present.
Because hilsa herring has been under an embargo and has fished for, some aquaculture businessman introduces American shad from the U.S. at present.American shad (
Alosa sapidissima) be under the jurisdiction of Pacific herring shape catalogue, Clupeiformes, clupeidae, Alosa, with bright, tender, beautiful and well-known, profile and the big or small basically identical of it and the Changjiang river hilsa herring, the nutritive value of the two is also basic identical.American shad is sea, river migration fishes, is food with the plankton.Stop during the breeding migration ingesting or seldom ingesting, disperse at ordinary times to inhabit the coastal waters at the middle and upper levels, the end of spring and the beginning of summer (April-June) river breeding migration of tracing back, the back parent population that lays eggs returns the sea, juvenile fish then enters forage in tributary or the lake, goes into the sea after autumn and fleshes up, until sexual maturity.American shad is impatient, and the speed of moving about, ingest is rather rapid, and scale is bigger, very easily comes off, and Chang Yin is wounded and desquamation death by barrier.
The American shad seed rearing carries out in square cement pit, and the cement pit length of side is generally about 3-4m, the depth of water 0.5 ~ 1m.The parent population of American shad has just gone into nursery pond because it is impatient, in new environment activity rapid unusually, very easily bump repeatedly with the cement pool wall, cause death, bring the tremendous economic loss to the culturist.This kind unfavorable factor in view of in the present American shad seed breeding process is necessary to improve American shad seed breeding technology, in order to promote the breed of American shad better.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple and reasonable for structure, the tangible American shad breed of result of use pond is provided.
The technical scheme that provides according to the utility model, described American shad is cultured the pond, it comprises cultures pond body, support frame, the crashproof net of the crashproof net of sidewall and bottom, in culturing the pond body, be provided with support frame, at support frame the crashproof net of the sidewall that is tubular is installed, is connected with the crashproof net in bottom in the bottom of the crashproof net of sidewall.
The crashproof net of described sidewall and the distance of culturing between the body sidewall of pond are 0.2 ~ 0.3m.
The crashproof net in described bottom and the distance of culturing between the body bottom surface, pond are 0.2 ~ 0.3m.
Described support frame by two steel rings up and down and up and down the connecting reinforcement bar between two steel rings connect and compose.
The utility model has farthest avoided American shad when just going into the ordinary cement nursery pond, because impatient, cause and collides repeatedly with pool wall and produce large batch of death; Also avoided when collecting the fertilized egg of mating generation, causing startling hilsa herring.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
This American shad is cultured the pond, it comprises cultures pond body 1, support frame 2, the crashproof net 3 of sidewall and the crashproof net 4 in bottom, in culturing pond body 1, be provided with support frame 2, at support frame 2 the crashproof net 3 of the sidewall that is tubular be installed, be connected with the crashproof net 4 in bottom in the bottom of the crashproof net 3 of sidewall.
The crashproof net 3 of described sidewall and the distance of culturing between body 1 sidewall of pond are 0.2 ~ 0.3m.
The crashproof net 4 in described bottom and the distance of culturing between body 1 bottom surface, pond are 0.2 ~ 0.3m.
Described support frame 2 by two steel rings up and down and up and down the connecting reinforcement bar between two steel rings connect and compose.
In the utility model, support frame 2 is made by the reinforcing bar of diameter about 2cm, and the crashproof net 3 of sidewall is that the nylon cloth of PA66 is made by model, and the crashproof net 4 in bottom is made by common nothing joint net sheet.
During making, at first become columniform support frame 2(to be generally 3.5m left and right sides diameter with reinforcement fabrication, high about 1m), support frame 2 comprises two steel rings up and down, utilizes reinforcing rod (generally needing 4) to couple together, and plays fixation; With wrapping with nylon cloth around the cylindrical support skeleton of putting up 2, form the crashproof net 3 of sidewall; Save the bottom that the net sheet seals the crashproof net 3 of sidewall with common nothing, form the crashproof net 4 in bottom.Support frame 2, the crashproof net 3 of sidewall are put in the breed pond body 1 with the integral piece of the crashproof net 4 in bottom, support frame 2 is fixed on each limit of culturing pond body 1 with nylon rope, there is the distance of 0.2 ~ 0.3m the bottom surface of the crashproof net 4 in assurance bottom and breed pond body 1, and the pool wall of the crashproof net 3 of sidewall and breed pond body 1 also has the distance of 0.2 ~ 0.3m.
American shad can be put into net like this cultures, because crashproof net 3 softnesses of nylon cloth sidewall, wearability is good, cost is low, the mechanical strength height, can use repeatedly, can effectively avoid or slow down the collision of hilsa herring, the crashproof net 4 in bottom is designed to common nothing joint net sheet, can be so that the fertilized egg that the hilsa herring post-coitum produces sees through crashproof net, be sunken to the cement pit bottom, be convenient to the breed personnel and letting alone under the situation of hilsa herring, collect fertilized egg.
