Abstract

The invention relates to a method for using a device for quantitative investigation of Chinese mitten crab early resources. The device includes a pipe column, a water pump, a collection filter and a hand-made net. The pipe column is a transparent hollow cylinder structure and the side wall is marked with a height scale , the suction port of the water pump is connected with the water inlet pipe, the other end of the water inlet pipe extends into the inner cavity of the pipe string, and the water outlet of the water pump is connected with the mesh port of the collection filter screen through the water outlet pipe. The invention can fully sample the early resources of Chinese mitten crabs in different water layers and inhabit the water bottom or hide in the bottom of the water, so as to ensure the accuracy of statistical data, realize accurate quantitative investigation of the early resources of Chinese mitten crabs, and effectively It is beneficial to improve the accuracy of the assessment of the overall level of the early resources of the Chinese mitten crab, and the device has a simple structure and is easy to operate, and is convenient for investigation and research in the field.

Description

technical field [0001] The invention belongs to the technical field of aquatic resources investigation, and in particular relates to a method for using a device for quantitative investigation of early resources of Chinese mitten crab. Background technique [0002] The natural resource of Chinese mitten crab is not only an important fishing target in my country, but also a source of excellent germplasm that supports the green and healthy development of the aquaculture industry. However, under the influence of multiple pressures such as climate change and human activities, the natural resources of Chinese mitten crabs fluctuate drastically, which has attracted widespread attention. The early developmental stage is a very important key link in the entire life history of organisms, which is related to the effective replenishment and sustainable development of the entire population. Therefore, investigating the dynamic characteristics of the early resources of the Chinese mitten...
