Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device suitable for large benthic animals in water bodies. Background Art

[0002] Benthic animals are a crucial component of the food web. They serve as a food source for upper-level consumers (such as fish and birds) and maintain energy and material cycles by consuming organic debris and algae in sediments. Through bioturbation, benthic animals promote the redistribution of sedimentary materials and the release of nutrients, thereby influencing the productivity and ecological function of water bodies. Furthermore, benthic animals are highly sensitive to environmental changes and serve as important bioindicators for assessing water quality and ecosystem health.

[0003] However, benthic animals often live in muddy environments, making survey and sampling difficult. Traditional survey tools are complex to make and often get stuck in the mud during use, making them inconvenient to use and making it impossible to obtain samples. Therefore, it is urgent to design a new sampling tool that can only scrape benthic animals and avoid getting stuck in the mud. Utility Model Content
