The front end of described aqueduct (7) is mounted with filter screen.
The operation principle of the present invention:
Within anti-wave fish idiophase, device each several part of being laid eggs by ramp type carries out assembling and being placed in fishpond, height of water level in regulation fishpond, makes the fishpond water surface slightly above lay eggs a lowermost half space；Drawn water from fishpond by aqueduct or water inlet system is fetched water, existence due to water-head, water can flow downward from top layer half space, eventually arrive at the fishpond water surface, thus in bed of laying eggs, form stable, uniform descending current, the flow velocity of descending current can be controlled by the valve on regulation aqueduct, thus meet the anti-wave fish demand to flow rate of water flow when laying eggs.
Owing to anti-wave fish has upstream habit when breeding, the anti-wave fish in fishpond can go to a top trip of laying eggs from the half space that bed of laying eggs is minimum；Owing on impact platform, current are very fast, add anti-wave fish constantly to rub between fish body with Fibra Trachycarpi, stone and adjacent anti-wave fish during travelling, anti-wave fish upstream on impact platform can be produced obvious stimulation so that fish roe is produced on the Fibra Trachycarpi and stone of trip warp by female anti-wave fish.Fibra Trachycarpi and block faces are the most coarse, can be the most bonding with fish roe, reach the effect of fixing fish roe.Sperm is entered after being upset and lays eggs in a water by male anti-wave fish so that in obstetric table, in descending current, anti-wave fish sperm concentration is higher.Current containing high concentration milt flow down along bed of laying eggs, and are combined with being fixed on the fish roe on Fibra Trachycarpi and stone, hence it is evident that increase the efficiency that anti-wave milt combines with fish roe, improve germ cell total quantity.
Antagonism wave fish physical demands of laying eggs owing to sailing against the current is huge, so arranging half space between impact slope.Half space front end is provided with water fender, and platform can gather the water of certain depth so that on half space, on current mean flow rate Charpy slope, mean flow rate is low, provides, laying eggs, the place that anti-wave fish regains one's strength on bed.The anti-wave fish of antisecosis may proceed to upper layer impact slope trip and goes, and continues row's essence of laying eggs.Aqueduct front end arranges filter screen, has both been possible to prevent anti-wave fish adverse current to swim in pipe, also may filter that granule foreign in water.Anti-wave fish, after having laid eggs, can go downstream, again trip Hui fish pond.During laying eggs, owing to there being stable, uniform current in obstetric table, in obstetric table, the vigor of germ cell can obtain intact holding.Again because fish roe is effectively connected with Fibra Trachycarpi, stone, therefore can be using Fibra Trachycarpi and stone as the effective carrier of fish roe.After the process of laying eggs terminates, only Fibra Trachycarpi and stone need to be taken out in bed of laying eggs, the later stage process such as the fish roe that can facilitate on which carries out disinfection, hatching.
After after terminating idiophase, device of being laid eggs by ramp type splits into independent part, can remove fishpond easily, and can reuse
Beneficial effects of the present invention:

(2) in increasing idiophase, anti-wave fish lays eggs and arranges essence total quantity.Half space is owing to being mounted with water fender in front end, the water of certain depth can be put aside, in making platform, current mean flow rate is significantly lower than the mean flow rate on impact slope, provides the region of rest for upstream anti-wave fish, and the recovery effects of antagonism wave fish muscle power is obvious.Anti-wave fish after antisecosis can continue up one layer of impact slope and move about, and proceeds breeding, thus increases the total quantity that anti-wave fish fish roe is discharged with milt.
(3) efficiency of sperm ovum binding is improved.Fibra Trachycarpi and crushed stone in bed of laying eggs can effectively fix fish roe, and sperm is arranged in bed of laying eggs by male anti-wave fish, and in bed of laying eggs, sperm concentration is high, and the current containing high concentration sperm are lower along slope has contacted sperm ovum binding with fish roe, is greatly improved fish roe rate of fertilization.
(4) facilitate fish roe to collect to process with the later stage.Owing to germ cell and Fibra Trachycarpi, rubble have effective adhesive, palm-bark rain cape and rubble just to become catcher and the carrier of germ cell.After anti-wave fish completes breeding, can easily palm-bark rain cape and rubble be taken out from bed of laying eggs, and carry out carrying as carrier germ cell on which, sterilize, the follow-up work such as hatching.
(5) device installation, dismounting, convenient in carrying.Device half space, impact slope, vertical pillar, horizontal support, aqueduct and water control valve are all detachable, assemble and also facilitate.Plastic sheeting, Fibra Trachycarpi, rubble are cheap and easy to get, the most durable.
