A controlled experimental device and construction method for simulating the habitat of tidal flat fish

Abstract

The invention relates to a controlled experimental apparatus for simulating a beach fish perch habitat, and a construction method thereof. The controlled experimental apparatus comprises a habitat controlled experiment device and an intelligent tide level simulation device, wherein the habitat controlled experiment device comprises a breeding box, a tidal creek is arranged in the middle of the breeding box, the flood tide direction of tide submerges the upper portion area of the tidal creek, the interior of the breeding box and both sides of the tidal creek are respectively connected to grassless beach and salt marsh vegetation, the side surface of the breeding box is provided with the intelligent tide level simulation device, the breeding box is connected to the intelligent tide level simulation device respectively through a water inlet pipe and a water outlet pipe so as to be used for water circulation in the breeding box, the intelligent tide level simulation device comprises a cubic box, an intelligent water pump is arranged on the right side of the cubic box, and is connected to the water outlet pipe, the side surface of the intelligent water pump is provided with a water level regulation device, and the intelligent water pump is connected to the water level regulation device through a circuit. According to the present invention, the controlled experimental apparatus is the good device for studying the fish perch habitat, and has advantages of generalizability and ease operation.

Description

technical field [0001] The invention belongs to the technical field of tidal flat habitat investigation and controlled experiment, in particular to a controlled experimental device and construction method for simulating the habitat of tidal flat fish. Background technique [0002] Estuarine wetlands have rich topographic features and habitat differences, especially in the tidal flat waters of the intertidal zone. In this special habitat of the intertidal zone, the structure and composition of subhabitats (mainly tidal trenches, light flats and salt marsh vegetation) are different It has an important impact on the distribution, density and feeding strategy of fish, and fish also have different feedback mechanisms and adaptation mechanisms to different subhabitat types. There is a large area of ​​intertidal salt marsh wetland in the Yangtze River Estuary, and the habitat types are diverse and complex. There are mainly three types of subhabitats: tidal trench, salt marsh and li...

Problems solved by technology

The traditional indoor controlled experimental device is generally a simulation of a single habitat, and it is mainly aimed at the simulation of the breeding environment of the cultured species, which cannot represent the characteristics of the natural environment in the wild.
