By water pump toward fish movement region water filling, until the depth of water (is less than or equal to the first wall 10 in desired depth
Highly).
S1.2, fish to be tested is placed in barrier net 30.Fish to be tested can be a species or multiple species
Fish.After fish to be tested is put into barrier net 30, may wait for (such as 2 hours) for a period of time and facilitate fish to be adapted to.
S1.3, unlatching underwater lamp 11, barrier net 30 is extracted out from the inner side of the first wall 10, records the behavior of fish to be tested
And distribution, analyze the phototaxis of fish.
In step S1.3, after extracting barrier net 30 out, the photochromic trip that fish to be tested can be liked according to it is to corresponding test
Region 50.
The behavior of fish to be tested and distribution can be recorded by camera head 80.Therefore, step S1.3 it
Before, the visual angle of size and angle adjustment camera head 80 always according to each test zone 50 makes test zone 50 entirely fall into it
In angular field of view, whole monitored area monitored picture is complete.
Second embodiment of the research fish of the invention method of testing of factor selection to external world, research fish is to the flow velocity of water
Selection.With reference to Fig. 1,2, the selection of the research fish to the flow velocity of water is comprised the following steps：
S2.1, toward the fish movement region water filling in the first wall 10, the multiple test zones 50 of water filling of injection and
The inner space of barrier net 30.Wherein, by water pump toward fish movement region water filling, until the depth of water desired depth (be less than or
Equal to the height of the first wall 10).
S2.2, to the outside water filling of the first wall 10, the outside of the first wall 10 is formed with the multiple of correspondence test zone 50
Aquifer zones, are that flow velocity mouthful 12 provides pressure differential.
Wherein, step S2.2 may include：
S2.2.1, peripheral the second wall 20 that annular is set in the first wall 10, the second wall 20 and the first wall 10
Between be formed with the water storage space 60 of an annular.The interval of multiple dividing plates 70 is laid in water storage space 60, by water storage space 60
Be separated into it is multiple respectively with the corresponding aquifer zones of test zone 50.
S2.2.2, by water pump respectively to multiple aquifer zones supply water.Each aquifer zones can be supplied water by a water pump,
By water pump toward aquifer zones water filling, until certain altitude, reaches the head difference between aquifer zones and fish movement region
Preset value.
S2.3, fish to be tested is placed in barrier net 30.Fish to be tested can be a species or multiple species
Fish.After fish to be tested is put into barrier net 30, may wait for (such as 2 hours) for a period of time and facilitate fish to be adapted to.
The flow velocity mouthful 12 of S2.4, open test zone 50, makes the water of aquifer zones with predetermined flow velocity by flow velocity mouthful 12
Flowed to corresponding test zone 50.
