Abstract
The utility model relates to a fertilized egg incubator for northern pike, and provides a device used for separating the dead eggs attached by water mold so as to improve the hatchability of the fertilized eggs and conveniently collect the hatched fish fries by controlling the water velocity and the flow quantity. The fertilized egg incubator adopts the technical scheme that a fertilized egg hatching tank, a water pipe, a water pump, a water meter, a water flow control valve, a water tank and a net cage are included, and is characterized in that a water outlet hole is drilled at the upper part of one side wall of the fertilized egg hatching tank, the water outlet hole is connected with a water outlet pipe, and the water outlet pipe is connected with a plastic flexible pipe to lead to the net cage in the water tank; a water inlet hole is drilled at the bottom of the fertilized egg hatching tank, a water inlet pipe is arranged at the water inlet hole, and a hemispheroidal or umbrella-shaped spraying nozzle with a plurality of jet holes is connected at one end of the water inlet pipe to extend in the fertilized egg hatching tank; and the water inlet pipe at the lower part of the fertilized egg hatching tank is connected with the water meter, the water flow control valve and a submerged pump arranged in a water accumulation pool in sequence. The utility model is used for hatching the fertilized eggs of the northern pike.
Description
Technical field
The utility model relates to the incubating oosperm of northern pike device.
Background technology
Pike (Esox lucius) is commonly called as pike, belongs to salmon shape order (Salmoniformes), Esocidae (Esocidae), originates in basin, northern Eerqisihe River, Xinjiang.During annual waters freezing thawings, 8 ℃ of left and right sides pikes of water temperature begin breeding, and lack breeding period, only 1 month, and the male and female gonad development is asynchronous, and the milter gonad maturity is than more than the late two weeks of raun, 8～16 ℃ of hatching water temperatures, 13～14 ℃ of optimum water temperatures, incubating oosperm needs 6～7 days.Lower at natural world pike mating rate, incubation rate, survival rate of fish fry is low.
Because pike hatching water temperature is on the low side and incubation cycle is long, this water temperature range also is the easiest emergence period of water mold, and therefore the control water mold is to obtain the successful key of hatching during incubating oosperm of northern pike.The hatching frame of domestic useful similar sturgeon incubating oosperm is hatched.But because the growth of pike male and female is asynchronous, fertilization rate is low, can only take manually to choose the way of dead ovum, and efficient is very low, very easily causes water mold to pollute again, causes hatching all to fail when serious.
The utility model content
The utility model technical issues that need to address provide a kind of energy by controlled water flow speed and flow, separate the dead ovum that adhered to by water mold, improve hatchability of fertile eggs, be convenient to collect the equipment that hatches fry.
The technical solution of the utility model is made up of incubating oosperm groove, water pipe, water pump, water meter, water control valve, tank and net cage, it is characterized in that boring an apopore in a side wall upper part of incubating oosperm groove, and at outlet pipe of this apopore connection, this outlet pipe connects a plastic flexible pipe and leads to the net cage that is placed in the tank; The incubating oosperm trench bottom bores an inlet opening, and adorns a water inlet pipe in this inlet opening, and the end that this water inlet pipe stretches into the incubating oosperm groove connects hemisphere face shape or the umbrella shape nozzle that an edge is provided with a plurality of spray orifices; Water inlet pipe in incubating oosperm groove bottom connects water meter, water control valve successively and is located at immersible pump in the cistern.
The utility model is because controlled water inlet water velocity and flow, nozzle in the incubation tank bottom is sprayed water continuously, oosperm of northern pike is evenly rolled, in dead ovum imbibition phase and water mold outbreak period, impel the dead ovum of suction come-up to separate, guarantee the normal hatching of fertilized egg from the outlet pipe discharge.After fry hatched out substantially, fry all was expelled to net cage from outlet pipe and collects.The utlity model has the raising hatchability of fertile eggs, be convenient to collect the advantage that hatches fry, can improve the pike incubation rate more than 20%.
Description of drawings
What accompanying drawing was represented is structural representation of the present utility model.
Embodiment
The utility model (seeing accompanying drawing) is made up of incubating oosperm groove 1, water pipe, immersible pump 10, water meter 7, water control valve 8, tank 3 and net cage 4; Incubating oosperm groove 1 adopts thickness 10mm glass to make, it is wide at the top and narrow at the bottom trapezoidal that the sidewall of incubating oosperm groove 1 becomes, trapezoidal last bottom width 500mm, following bottom width 200mm, high 1000mm, be seamed into up big and down small truncated rectangular pyramids shape by 4 blocks of above-mentioned trapezoidal glass with the bonding corner connection of silica gel, continue to use the bonding square floor of silica gel at truncated rectangular pyramids shape end opening; Can fix with brandreth in the outside of incubating oosperm groove 1; Side wall upper part at incubating oosperm groove 1 is bored a diameter 40mm apopore apart from base plate 900mm, and at this apopore bonding outlet pipe 2 of silica gel, this outlet pipe 2 connects a plastic flexible pipe and leads to the net cage 4 that is placed in the tank 3; Net cage 4 adopts mesh 40 bolting silks, net cage 4 long 700mm, wide 600mm, high 500mm; Incubating oosperm groove 1 bottom center is established a diameter 40mm inlet opening, this inlet opening bonding external diameter 40mm water inlet pipe 5 of silica gel, water inlet pipe 5 stretches into incubating oosperm groove 1, and stretch at 20mm place, distance incubating oosperm groove 1 bottom surface an edge be provided with the hemisphere face shape of a plurality of spray orifices or umbrella shape nozzle 6 inner chamber and with the inlet opening welding of nozzle 6; Nozzle 6 internal diameter 190mm, the thick 5～8mm of the shell of nozzle 6 establishes an aperture 2mm spray orifice apart from the wall body at 10mm place, nozzle 6 edge every 10mm; Water inlet pipe 5 in incubating oosperm groove 1 bottom connects water meter 7, water control valve 8 successively and is located at immersible pump 10 in the cistern 9.
When the utility model uses, put into about 50,000 in fertilized egg at every turn, import the phreatic water of 12 ℃ of water temperatures (electrical bar temperature control), oxygen content 7～9mg/L continuously, oosperm of northern pike is evenly rolled from the incubator bottom nozzle.Incubating oosperm adopts the measure of controlled water flow speed and flow (with valve and flowmeter control) flowing water hatching under the low light level, preceding 1～3 sky and water current control of fertilized egg is at 3～4L/min, subsequently the 4th～6 day was dead ovum imbibition phase and water mold outbreak period, current are controlled at 6～8L/min, impel the dead ovum (being adhered to by water mold basically) of suction come-up to separate, guarantee the normal hatching of fertilized egg from the outlet pipe discharge.After treating that fry hatches out substantially, current should be controlled at 8～9L/min, fry all is expelled to net cage from outlet pipe collects.
