Abstract
The utility model relates to a modified fish egg taker which comprises a handheld part (1) and a puncture part (2). The handheld part (1) is a sheet with smooth edge. The puncture part (2) is connected to the handheld part (1). The puncture part (2) is a puncture needle with 'V'-shaped cross section. The top end of the puncture part (2) is a blunt, and the cutting head bottom of the puncture part (2) is connected with the handheld part. The modified fish egg taker is made of stainless steel, the surface of the modified fish egg taker is smooth, the top end of the puncture part is blunt, and the modified fish egg taker is capable of effectively protecting ovaries in taking eggs. A groove of the puncture part is long, and required eggs can be taken effectively, so that operating efficiency is improved. The modified fish egg taker is widely applicable to artificial breeding of cultured fishes.
Description
Technical field
The utility model belongs to aquatic animal experiment equipment manufacturing technology field, particularly relates to a kind of modified fish and gets egg apparatus.
Background technology
The seed source that fish culture is produced mainly is the approach through artificial propagation.Though just beginning freshwater before more than 3000 years, China breeds fish, not long to the history of the artificial propagation of cultured fishes.China succeeds to " four large Chinese carps " artificial propagation first from late 1950s, and technology is constantly perfect, and progressively is applied to the artificial breeding of other seawater fishs, has obtained higher production efficiency.Artificial propagation of fish depends primarily on the gonad development state of parent population.The selection most important condition of parent population is that gonad development is good, secondly is that anosis nothing is hindered.Judge in the production that well whether the parent population gonad development, mainly differentiate from outward appearance according to experience, also can directly get ovum to raun and observe.At present common get egg apparatus common plastics or feather etc. are made, show rough, damage ovary easily when getting ovum; Moreover the common egg apparatus puncture portion fluting got is shorter, and disposable to get ovum less, and operating efficiency is low.Therefore, need a kind of structure more reasonable, practical, get egg apparatus easily.
Summary of the invention
The utility model technical problem to be solved provides a kind of modified fish and gets egg apparatus, damages ovary, the inferior problem of inefficiency in the prior art easily to solve.
The utility model solves the technical scheme that its technical problem adopted: provide a kind of modified fish to get egg apparatus; Comprise Handheld Division and puncture portion; Said Handheld Division is a thin slice that outer rim is smooth, and said Handheld Division connects a puncture portion, and said puncture portion is the pricker of a cross section for " V " shape; Said puncture portion top is a blunt round, and an incision bottom is connected with the Handheld Division.
Said puncture cross section is 60 ° for the angle of " V " shape.
As a whole of said Handheld Division and puncture portion.
Said Handheld Division and puncture portion are processed by stainless steel material.
Beneficial effect
The present invention is made by stainless steel material, smooth surface, and puncture portion top blunt round is got ovum and can effectively be protected ovary; Puncture portion fluting is longer, can effectively get required ovum grain, increases work efficiency; Can be widely used in the artificial propagation of cultured fishes.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1; A kind of egg apparatus of getting comprises Handheld Division 1 and puncture portion 2, and said Handheld Division 1 is a thin slice that outer rim is smooth; Said Handheld Division 1 connects a puncture portion 2; Said puncture portion 2 is cross section prickers for " V " shape, and said puncture portion 2 tops are blunt round, and an incision bottom is connected with the Handheld Division.
Said puncture portion 2 cross sections are 60 ° for the angle of " V " shape.
Said Handheld Division 1 and 2 as a whole in puncture portion.
Said Handheld Division 1 and puncture portion 2 are processed by stainless steel material.
During use, hand-held get egg apparatus Handheld Division 1, puncture portion 2 correctly and is gently inserted in the raun gonopore, on the low side to the left or to the right then being permitted slightly firmly inserted ovary, and it is several down to get the egg apparatus rotation, extracts out gently and can obtain required ovum grain.The ovum grain that takes out is with the naked eye directly observed or is handled the back with transparent liquid and observe.
Claims (4)
1. modified fish are got egg apparatus; Comprise Handheld Division (1) and puncture portion (2), it is characterized in that said Handheld Division (1) is a thin slice that outer rim is smooth; Said Handheld Division (1) connects a puncture portion (2); Said puncture portion (2) is the pricker of a cross section for " V " shape, and said puncture portion (2) top is a blunt round, and incision end end to end is connected with the Handheld Division.
2. a kind of modified fish according to claim 1 are got egg apparatus, it is characterized in that, said puncture portion (2) cross section is 60 ° for the angle of " V " shape.
