Problems solved by technology
[0002]Now there are two major problems in the development of fish farming in lakes and reservoirs. One is that putting in a lot of feed will bring about enrichment of water resources and damage the natural water environment
Second, due to the deep depth of most lakes and reservoirs, it is difficult to catch individual cultured fish after they grow up. The existing fish aquaculture system cannot test the living behavior of fish, because the current fishing system and the fishing nets used are all It is just a layer of net, and it is impossible to distinguish the habits of fish living in each water layer

Embodiment 1
[0017] Fish behavioral biology testing device, its composition comprises: fish aquaculture system 1, described fish aquaculture system comprises the fishing system 6 of measuring fish habitat behavior, fish tank 13, adjustable frequency sound wave generator 11, The fish aquaculture system includes a video surveillance system 10 and an oxygen enricher installed outside the fish tank.
[0018] In the fish behavioral biology testing device, the fish tank 13 is connected to the left and right guide cable fixing frames 15 of the fishing net, and the described frequency-adjustable sound wave generator 11 is fixed on the left and right guiding cable fixing frames 15 of the fishing net. Sand filter 12 position is not fixed in 13, is generally installed in the fish tank bottom, and described fish tank 13 tops are equipped with bait throwing machine 14.

Embodiment 2
[0023] Fish behavior biology test device described in embodiment 1, described fish habitat behavior fishing system can fish different kinds of fish, fish with different habitat behaviors, such as silver carp, bighead carp, carp, Crucian carp, catfish, red trout, sturgeon, and snout sturgeon have the habit of inhabiting the upper, middle, and lower water layers, which can make better use of the learning of different habitats of fish to guide the development of deep waters such as lakes and reservoirs in our country. In fishery production, rationally match fish species to adapt to the production mode of ecological fishery, rotation catch and release.
[0024] working principle:
[0025] The same or different species of fish are cultured simultaneously in the same environment in the laboratory to observe and monitor fish behavioral biology. The automatic pellet feeding machine can automatically set the 24-hour cycle timing and quantitative feeding of pellet feed. The oxygen-enri...

Abstract
The invention relates to a biological test device for fish behaviors. The development of fish culture in lakes and reservoirs in the prior art faces two difficulties: 1, the throw of a large amount of feed can cause eutrophication of water resources and destroy natural water environment; and 2, since water in most of lakes and reservoirs is too deep, cultured fish individuals are difficult to catch when growing up, and since habits of fishes living in different water layers can not be distinguished as a result of the fact that a fishing net of the traditional fishing system in the prior art is simply a single-layer net, the traditional fish aquatic culture system can not be used for testing life behaviors of fishes. The biological test device for fish behaviors comprises a fish aquatic culture system (1), wherein the fish aquatic culture system (1) contains a fish perching behavior-based fishing system (6), a fish tank (13) and a frequency-adjustable sound generator (11), and the outside of the fish aquatic culture system (1) is provided with a video monitoring system (10) and an oxygenator. The invention is used for testing habits of fishes.
Description
Technical field: [0001] The invention relates to a testing device for testing the activity rule of fish. Background technique: [0002] Now lakes and reservoirs are facing two major problems in the development of fish farming. One is that putting in a large amount of feed will bring about eutrophication of water resources and destroy the natural water environment. Second, due to the deep depth of most lakes and reservoirs, it is difficult to catch individual cultured fish after they grow up. The existing fish aquaculture system cannot test the living behavior of fish, because the current fishing system and the fishing nets used are all It is just a layer of net, and it is impossible to distinguish the habits of fish living in each water layer. Contents of the invention [0003] The object of the present invention is to provide a kind of fish behavioral biology test device that is used for indoor fish of the same or different species to observe, domesticate and test fish b...
