Problems solved by technology

When carrying out artificial reproduction, it is necessary to catch the four major domestic carps from the broodstock breeding pond and then put them into the spawning pond for induced labor and breeding. Among them, when the induced labor is performed, the female fish and the male fish need to be injected with oxytocic agents respectively, and the female Fish are injected with two injections and male fish with one injection to complete the work of induced labor. After the fish are entwined in the spawning pond, the mixing of sinking eggs and floating eggs in the spawning pond is not conducive to hatching separately. However, the existing technology There is no equipment for separating fish eggs, which only relies on natural sedimentation and separation of fish eggs, which is not efficient

Embodiment 1

[0048] see figure 1 , 2 , 5-11, a collection and separation component device for fish eggs, comprising:

[0049] Spawning pool 10, in the spawning pool 10, at least one egg retrieval pump 12 is hoisted through the depth adjustment member 13 to set at least one egg retrieval platform 20 on the side of the spawning pool 10,

[0050] The ovum separation assembly 40 is arranged on the ovum retrieval platform 20 and connected to the ovum retrieval pump 12 through the ovum retrieval tube 11,

[0051] Wherein, the egg separation assembly 40 comprises a cylindrical egg separation shell 49, the egg separation shell 49 is fixed on the ovum retrieval platform 20 with the axis perpendicular to the horizontal plane, and the egg separation shell 49 has a circular cylindrical surface The center is provided with an egg inlet 44 and is connected to the egg extraction pump 12 through the egg extraction tube 11. The circular cylindrical surface at the bottom of the egg separation shell 49 is a...

Embodiment 2

[0065] see Figure 12 As shown, the method for collecting fish roe using the collection and separation component device of fish roe, the steps are as follows:

[0066] -collect fish roe in the pond with ovum extraction pump 12;

[0067] - separating sinking fish eggs and buoyant fish eggs through the egg separation module 40 and utilizing the sinking and buoyancy of fish eggs;

[0068] - Send the separated fish eggs vertically downwards into the storage container with a transparent tube, and use a counter to count the number of fish eggs during the sending process;

[0069] - Use the optical signal transmitter 64 to irradiate the fish eggs moving downward from the transparent tube, receive the optical signal irradiating the fish eggs through the optical signal receiver 61 and feed back the acquired data to the control unit 60 to judge the activity of the fish eggs, and the control unit 60 calculates the activity of the eggs The body light transmittance is used to judge the e...

Embodiment 3

[0075] Fish egg separation test:

[0076] Separation group 1, separation group 2, and separation group 3 are respectively set up to carry out separation tests on fish eggs containing sinking eggs and floating eggs. The fish eggs separated by each group are 10,000 in total, and the sinking eggs and floating eggs are each 5,000. Separation groups 1-3 all adopt 40 pairs of fish roe separation work of the ovum separation assembly among the embodiment 1, wherein separation group 1 uses such as figure 2 The ovum separator 410 in the separation group 2 is used as image 3 Terminal ovum separation divider 410, separation group 3 using as image 3 Split the ovum dividing plate 410 in the middle.

[0077] The ovum separation driver 48 adopts the rotating speed of 20r / min (flow velocity is 0.1 ± 0.05m / s) to carry out the ovum separation work, and the result of counting the time spent by each separation component ovum is as follows: Figure 13As shown, and the egg separation accuracy ...

Abstract

The invention discloses a collection and separation component device and collection method of fish eggs, which belong to the technical field of fish reproduction. The device of the invention includes: a spawning pool, the spawning pool has buoyancy and the bottom of the spawning pool is connected to an egg collection pump by a depth adjustment member. On the side of the spawning pool, there is an egg retrieval platform and an egg separation component, which is set on the egg retrieval platform and connected to the egg retrieval pump through the egg retrieval tube. The egg separation component includes a cylindrical egg separation shell, and the egg separation The shell is fixed on the egg retrieval platform with the axis perpendicular to the horizontal plane. The center of the circular cylinder at the bottom of the egg separation shell is provided with an egg inlet and connected to the egg retrieval pump through the egg retrieval tube. The bottom of the egg separation shell is The circular cylindrical surface is also connected with a sinking egg outlet tube. The invention realizes the rapid collection of fish eggs and the rapid separation of floating eggs and sinking eggs by centrifugation, effectively improving the separation rate of fish eggs. Obtain relevant data such as the number of fish eggs, fish egg activity, and fish egg density, with high data accuracy.

Description

technical field [0001] The invention belongs to the technical field of fish reproduction, and in particular relates to a fish egg collection and separation component device and a collection method. Background technique [0002] The four major carps refer to artificially raised herring, grass carp, silver carp and bighead carp. Since the 1950s, Chinese aquatic science and technology workers have overcome the artificial reproduction technology of the four major carps, completely solving the problem of relying on river fishing for aquatic seedlings. The passive situation has promoted the overall development of the aquaculture industry. When carrying out artificial reproduction, it is necessary to catch the four major domestic carps from the broodstock breeding pond and then put them into the spawning pond for induced labor and breeding. Among them, when the induced labor is performed, the female fish and the male fish need to be injected with oxytocic agents respectively, and t...
