Embodiment 1

[0026] Such as figure 1 As shown, the experimental device for studying the behavior of fishes affected by light according to the present invention has a structure including a water tank 1, a double-layer sleeve, a transparent waterproof glass fiber reinforced plastic lampshade 5, an LED lamp group 6, a motor 8, a circuit control system 7 and video camera9.

[0027] The water tank 1 is a cylindrical fiberglass tank with a diameter of 2 meters and a height of 1 meter. The double-layer sleeve is made of opaque PVC material, and the double-layer sleeve is arranged in the water tank. The double-layer sleeve includes an outer circle Tube 2 and inner layer cylinder 3, the inner and outer cylinders of the double-layer sleeve all have a plurality of light-transmitting circular holes 4 arranged according to certain rules. In the present embodiment, the height of the double-layer sleeve of PVC material is 80 centimeters, and the diameter of the inner layer cylinder is 75 centimeters. Th...

Embodiment 2

[0034] The experimental device of the present invention is applied to the experiment of studying the influence of red light on the behavior of juvenile grouper fish with a body length of 15 cm. The water tank 1 used is a cylindrical glass fiber reinforced plastic tank with a diameter of 2 meters and a height of 1 meter. The PVC cylinder of the cylinder structure is made of opaque PVC material, the height of the double-layer sleeve is 80 cm, the diameter of the inner cylinder is 75 cm, and the inner and outer layers of the double-layer sleeve have 8 rows of light-transmitting round holes , the number of light-transmitting round holes in each column is 4, the number of round holes in each layer of sleeve is 4×8=32, the diameter of the round holes is 12 cm, the outer cylinder is fixed and cannot be rotated, and the inner cylinder is composed of Driven by the motor at the top, the motor and its transmission device are fixed on the base composed of transparent waterproof glass fiber...

Abstract

The invention discloses an experiment device used for researching effects on fish behaviors imposed by light and the application thereof. The experiment device comprises a water tank, a double-layered sleeve, a transparent waterproof glass reinforced plastic lampshade , an LED lamp pipe set, a motor, a circuit control system and a camera. According to the invention, by arranging a PVC cylinder of the double-layered sleeve, the experiment is carried out when fish freely swims in an experiment water tank, so via light transmitting holes in the PVC cylinder, experimental fish can freely swim in and out of the cylinder, and an ideal habitat is provided for the experimental fish, thereby simulating the free choices to light wave length and illuminance of the fish in natural sea and industrial aquaculture conditions in a more real manner. Thus, data deviation caused by harmful effect to the fish behaviors by improper structure and operation is avoided. Via the experiment device, many kinds of experiments on effect on fish behaviors imposed by light can be well finished, and the experiment device can satisfy many experimental objectives and requirements for researching effect on fish behaviors imposed by light.

Description

technical field [0001] The invention belongs to the field of biological research of aquatic animals, in particular to an experimental device for studying the behavior of fishes affected by light and its application. Background technique [0002] Fish behavior refers to the various movements of fish, which are the external responses of fish to environmental changes, mainly including swimming, feeding, reproduction, breathing and other behaviors; Movement forms are also included in the category of behavior. The purpose of studying fish behavior is to observe and record the behavior of fish, so as to clarify how and why fish behave in that way; at the same time, it is also to enrich the subject content of animal behavior, fish physiology and fish ecology, and contribute to fishery production and Environmental protection provides an important theoretical basis. Fish behavior is affected by various biotic and abiotic factors, among which light is an important environmental fact...
