The specific working principle of the invention is as follows: the submersible pump 9 is started, the jet flow injection device 4 injects water flow towards the first opening 11 at a certain flow speed to form forward jet flow parallel to the fish sampling channel 7, two rows of jet flows injected by the first group of jet flow injection device 41 and the second group of jet flow injection device 42 are quickly diffused in front of the fish sampling channel 7 to form a whole due to underwater resistance, and the peripheral water body of the jet flow is driven to move along the jet flow direction and extend to a far position underwater. The water flow characteristics formed after the first group of jet flow injection devices 41 and the second group of jet flow injection devices 42 inject the water flow simulate the water flow movement mode of a natural flowing water body or a closed pond water inlet to a certain extent. The water flow (jet flow) ejected by the first group of jet flow ejection devices 41 and the second group of jet flow ejection devices 42 drives the water bodies at the rear part and the side part to flow along the direction of the jet flow, and the water body in the fish sampling channel 7 is also influenced by the jet flow to form water flow in the same direction as the jet flow. Since most of the conventional cultured fishes naturally have the habit of top water play or reverse flow play, the top water of the cultured objects (fishes) moves reversely within the water flow influence range caused by the forward water flow, and is continuously gathered and close to the first group of jet flow injection devices 41 and the second group of jet flow injection devices 42 (especially, the effect is better in the closed pond water body) until entering the fish sampling channel 7 in the center of the fish collecting and sampling frame 1 (because the forward water flow has a driving effect on the peripheral water body, the water body in the middle of the two longitudinal water flows injected by the first group of jet flow injection devices 41 and the second group of jet flow injection devices 42 is caused to form a tendency of flowing towards the first opening 11 along with the jet flow, so that the water body in the fish sampling channel 7 is driven to flow towards the first opening 11 at a slower flow speed, and the forward water flow outside the fish sampling channel 7 towards the first opening 11 forms an outer circulation behind the side of the first jet flow spray heads 412 and the second jet flow heads 422). The fish entering the fish sampling passage 7 can only allow the fish to pass through the fish sampling passage 7 in a longitudinal single-tail mode in sequence and enter the fish temporary culture net cage 2 at the rear end due to the limitation of the width of the fish sampling passage 7. When fish pass through the fish sampling channel 7, optical sampling equipment arranged on non-contact type measuring device brackets 6 on two sides of the fish sampling channel 7 penetrates through a sampling window 5 (made of high-light-transmittance isolating material) on the outer side of the fish sampling channel 7 to measure and sample the physiological growth characteristics of the cultured objects in the fish sampling channel 7 with higher definition and identifiability. And the related sampling result is used for calculation and reduction of a later-stage non-contact equipment measurement algorithm into actual measurement data of the breeding object.

(1) The method utilizes the life habit that fishes move against the water top flow in the natural environment, adopts the mode of artificially manufacturing the one-way water flow of the underwater specific local area under water, naturally induces the fishes to move against the water top flow to automatically enter a sampling area, adopts a non-contact optical measurement mode to sample and record data of the physiological growth condition of the fishes, conveniently obtains the growth physiological information of the cultured objects in the water body at any time, and simultaneously reduces the interference stimulation and influence to the cultured objects in the sampling process. The cultured fishes flow reversely through the fish sampling channel and then enter the temporary culture net cages one by one (the fishes in the temporary culture net cages cannot swim out reversely due to the structural shape of the fish collecting sampling frame).
(2) This application drives peripheral water syntropy with two efflux that are on a parallel with fish sampling channel and flows, forms the one-way rivers of simulation in specific local area, lures to arouse fish adversity top current, moves about to get into fish sampling channel along rivers against the current, avoids the interference stimulus and the influence to the breed object.
(3) The fish after the sampling measurement is concentrated and temporarily stayed in the fish temporary rearing net cage at the rear end of the fish collecting sampling frame, the fish temporary rearing net cage can be used for measuring sampling and the like in other forms at any time, the rearing objects can be placed in the rearing water body at any time, and the situation that the same rearing object is possibly repeatedly sampled for multiple times in one-time sampling can be avoided.
(4) The utility model provides a trap and the whole completion of sampling process under water, not only convenient and practical, reduction that simultaneously can furthest is to the stimulus and the influence of breed object, is showing the adverse effect to breed object when having reduced the in-process measurement sampling of breeding.

2. The contactless fish sampling device for an aquaculture pond of claim 1 wherein the length of the sampling window is greater than 1.5 to 2 times the maximum length of the farmed objects and the width is greater than the maximum width of the farmed objects.
3. The non-contact fish sampling device for aquaculture ponds according to claim 1, wherein the temporary fish culture cage is provided with a cage release opening, and after the cage release opening is opened, the culture objects stored in the temporary fish culture cage are placed in a natural aquaculture water area.
4. The non-contact fish sampling device for aquaculture ponds according to claim 1, wherein the first group of jet flow injection devices and the second group of jet flow injection devices are communicated with a water main, the water main extends to the outer side of the fish collection sampling frame, the tail end of the water main, which is positioned on the outer side of the fish collection sampling frame, is connected with a submersible pump, the submersible pump supplies water to the water main, and the water main supplies water and pressure to the first group of jet flow injection devices and the second group of jet flow injection devices.
5. The non-contact fish sampling device in an aquaculture pond of claim 1, wherein the first water jet spray head comprises a plurality of water jet spray heads, and the plurality of water jet spray heads are arranged at intervals along the length direction of the water distribution pipe; the second water jet spraying head comprises a plurality of water jet spraying heads which are arranged at intervals along the length direction of the water distribution pipe.
6. The non-contact fish sampling device of claim 1, wherein the temporary fish farming cage is formed by splicing a plurality of meshes.
