Abstract

The utility model relates to an incubator, in particular to a salmon fertilized-egg incubator. The utility model solves the problems that the wetted area of a traditional old-style incubator is small, and the non-wetted dead angles of the fertilized eggs are quite easily generated in the old-style incubator to cause that water moulds are bred in water by the fertilized eggs, and the survival rate of the fertilized eggs is low. An inner barrel body is positioned in the middle of an outer barrel body, the upper end of the inner barrel body is clamped on the inner wall of the outer barrel body, a ring cavity is formed between the inner lateral wall of the outer barrel body and the outer lateral wall of the inner barrel body, a plurality of through holes are uniformly distributed and drilled on the lateral wall of the inner barrel body and the barrel bottom of the inner barrel body, and the lower end of a running-water pipe is positioned above the barrel bottom of the outer barrel body after penetrating through the barrel bottom of the inner barrel body. The non-wetted dead angles are not easily generated in the fertilized-egg incubator disclosed by the utility model, the exchange area of eyed eggs in a water body is increased, the breeding and the spreading of the water moulds are effectively inhabited, and the hatching rate of the salmon fertilized eggs is greatly increased.

Description

The salmon fishes oosperm hatcher

Technical field

The utility model relates to a kind of fishes oosperm hatcher.

Background technology

Salmon fishes has that fine and tender taste, nutritious, edible part are big, sting, be easy to characteristics such as processing between no flesh, the most important thing is protein content height in the muscle, and containing a large amount of unsaturated fatty acids, is one of China and even important in the world high-quality protein and source of nutriment.The salmon fishes great majority are lived water temperature below 20 ℃ for cold water fishes throughout the year, the breed variety of the main salmon fishes of China is an introduced variety, for example rainbow trout, golden trout, Atlantic salmon and hickie torgoch etc., the salmon fishes ovum is the heavy inviscid ovum of property, the thicker yolk content of egg membrane is more, blastodisc is less, and mature egg is orange-yellow.Because salmon fishes fertilized egg is lower and last longlyer to eyed eggs stage water temperature, so very easily grows water mold, causes lethality to increase.

Present domestic salmon fishes fertilized egg hatching facility, some old-fashioned incubator (see figure 2)s that the over-borrowing mirror is external, existing old-fashioned incubator discharge area is little, fertilized egg very easily produces only water dead angle in old-fashioned incubator, cause fertilized egg to grow water mo(u)ld in water, the survival rate of fertilized egg is low.

The utility model content

Existing old-fashioned incubator discharge area is little in order to solve, fertilized egg very easily produces only water dead angle in old-fashioned incubator for the utility model, cause fertilized egg in water, to grow water mo(u)ld, the problem that the survival rate of fertilized egg is low, and then a kind of salmon fishes oosperm hatcher is provided.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: salmon fishes oosperm hatcher of the present utility model is by exterior bowl, overflow pipe and inner drum are formed, the profile of described exterior bowl and inner drum is truncated conical shape, described inner drum is positioned at the middle part of exterior bowl, the upper end of described inner drum is installed on the inwall of exterior bowl, form ring cavity between the madial wall of exterior bowl and the lateral wall of inner drum, the bucket of the sidewall of described inner drum and inner drum is uniform on the end to have a plurality of through holes, and the bucket end that inner drum is passed in the lower end of overflow pipe is positioned at the top at the bottom of the exterior bowl bucket.

The utlity model has following beneficial effect: salmon fishes oosperm hatcher of the present utility model has a plurality of through holes in that the bucket of the sidewall of inner drum and inner drum uniform at the end, comparing with old-fashioned incubator has increased the discharge area greatly, has advantages such as water-based is good, the water exchange is fast; Be difficult for producing only water dead angle in the oosperm hatcher of the present utility model, increased the area that eyed eggs exchanges in water body, effectively suppressed growing and spreading of water mo(u)ld, improved the salmon fishes hatchability of fertile eggs greatly, the salmon fishes hatchability of fertile eggs is by bringing up to below 70% more than 85%, for the salmon fishes breed provides powerful guarantee.

Description of drawings

Fig. 1 is that the master of incubator of the present utility model looks schematic diagram, and Fig. 2 is the structural representation of old-fashioned incubator.

Embodiment

Embodiment one: in conjunction with Fig. 1 explanation, the salmon fishes oosperm hatcher of present embodiment is by exterior bowl 1, overflow pipe 2 and inner drum 3 are formed, the profile of described exterior bowl 1 and inner drum 3 is truncated conical shape, described inner drum 3 is positioned at the middle part of exterior bowl 1, the upper end of described inner drum 3 is installed on the inwall of exterior bowl 1, form ring cavity 4 between the lateral wall of the madial wall of exterior bowl 1 and inner drum 3, the bucket of the sidewall of described inner drum 3 and inner drum 3 is uniform on the end to have a plurality of through hole 3-1, and the bucket end that inner drum 3 is passed in the lower end of overflow pipe 2 is positioned at the top at the bottom of 1 barrel of the exterior bowl.

Embodiment two: in conjunction with Fig. 1 explanation, the upper end external diameter of the exterior bowl 1 of present embodiment truncated cone-shaped is greater than the lower end external diameter.So design, bucket 3 is fixing in helping,

bucket

3 and 1 sealing of outer bucket in making.Other composition is identical with embodiment one with annexation.

Embodiment three: in conjunction with Fig. 1 explanation, the upper end external diameter of the inner drum 3 of present embodiment truncated cone-shaped is greater than the lower end external diameter.So design has increased the fish-egg fish and has flowed into the water body contact area, ensures good mistake water-based, prevents that fish-egg is because of hypoxia death.Other composition is identical with embodiment one or two with annexation.

Embodiment four: in conjunction with Fig. 1 explanation, present embodiment through hole 3-1 is a manhole, and the aperture of through hole 3-1 is 3mm.So design, salmon fishes ovum footpath all more than 3mm, guarantee that fish-egg can not expose from through hole 3-1.Other composition is identical with embodiment three with annexation.

Embodiment five: in conjunction with Fig. 1 explanation, the internal diameter of the described overflow pipe 2 of present embodiment is 3.5cm.So design makes water body flow into from top, is flowed out by the bottom again, guarantees that current are unobstructed.Other composition is identical with embodiment four with annexation.

The course of work:

Salmon fishes fertilized egg is put into inner drum 3, to the water filling of the bottom of exterior bowl 1, continue after the fills with water in the exterior bowl 1 water in the exterior bowl 1 to be overflowed, finish until the salmon fishes incubating oosperm by overflow pipe 2 water filling in exterior bowl 1 by overflow pipe 2.
