Embodiment Construction

[0029] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited to the scope expressed in the examples.

[0030] Such as Figure 1-3 As shown, a fish temperature preference test experimental device is characterized in that it includes a main water tank 1 and a low-temperature water tank 2, the low-temperature water tank is connected to the main water tank 1 through a water delivery pipeline 9, and at least one temperature chain 3 is arranged in the main water tank 1 , which is vertically arranged, a plurality of temperature sensors 8 are installed on the temperature chain, a camera system 5 is also arranged in the main water tank, and a plurality of heating devices 4 are arranged in the main water tank from bottom to top.

[0031] In a preferred solution, the main water tank is provided with a layer of thermal insulation material 7 to isolate heat exchange with the outside world, so...

Abstract

The invention discloses a fish temperature preference testing experiment device which comprises a main water tank and a low temperature water tank, wherein the low temperature water tank is connectedwith the main water tank through a water conveying pipeline; the main water tank is internally provided with at least one temperature chain; the temperature chains are vertically arranged; a pluralityof temperature sensors are mounted on the temperature chains; the main water tank is also internally provided with a camera system; a plurality of heating devices are arranged inside the main water tank from bottom to top. As low temperature water inside the main water tank is heated at different layers, and a water temperature layering effect is observed through the temperature chains, simulation similarity of a water temperature layering structure is ensured; swimming process of fish individuals or groups in a layered water body is monitored and recorded through a camera mounted inside a water trough, and together with temperature chain observation data, temperature preference behaviors of fishes in a layered environment can be observed and studied.

Description

technical field [0001] The invention belongs to the field of aquatic products and fishery, and also relates to related fields such as water conservancy and hydropower engineering and fish behavior science, and specifically relates to an experimental device for testing temperature preference of fish. Background technique [0002] Most fish are temperature-changing organisms that live in water all their lives, and the selection behavior of fish on the temperature field can run through the entire life stage of fish. In the natural environment, because most fish cannot generate and obtain stable endogenous heat, they need to continuously exchange heat with the surrounding environment through the gills and body surface to maintain the body temperature consistent with the surrounding environment. Therefore, the ambient temperature directly affects the growth and development of fish, and indirectly affects the survival of fish. The construction of hydropower projects, especially t...
