A grass-type lake benthos collector

A benthic animal and collector technology, which is applied in fish farming, animal husbandry, fishing, etc., can solve the problem of poor collection effect, inability to collect submerged plants and surface mud samples at the same time, and inability to meet grass-type lake benthic animals. Collection requirements and other issues, to achieve the effect of accurate sample collection and flexible sampling depth

Problems solved by technology

However, for grass-type lakes, these mud collectors cannot collect submerged plants and surface mud samples at the same time, or the collection effect is very poor
All in all, the current collectors for benthic fauna can no longer meet the needs of collecting benthic fauna in grass-type lakes in the current research on aquatic ecosystems

Abstract

The invention discloses a grass-shaped lake benthic animal collector, which comprises a shell, a cutting board, a net pocket, a load-bearing cardboard and a double pull rope. The shell is fixed under the net pocket, the upper part of the shell is connected with the double pull rope, and the shell is installed inside Cutting board, the exterior of the shell is connected to the load-bearing card board; the cutting board can be used with double pull ropes to complete the cutting of surface sediments; the net bag can prevent the escape of benthic animals during the sample collection process, and can also be used for the initial screening of samples; load-bearing card The plate can determine the thickness of the surface sediment collected by the collector according to the scale line outside the casing; the double pull ropes are respectively connected with the casing and the cutting plate, and the descending and ascending operations of the collector are completed respectively. The grass-shaped lake benthos collector is easy to operate, can simultaneously collect submerged plants in grass-shaped lakes and benthic animals in surface sediments, and can improve the accuracy and efficiency of sampling.

Description

technical field [0001] The invention relates to the field of water ecological environment, in particular to a grass-type lake benthic animal collector. Background technique [0002] Benthos are groups of animals that live at the bottom of bodies of water. In addition to settled and active life, the forms of habitat are mostly fixed on hard substrates such as rocks and buried in soft substrates such as sediment. In addition, there are attached to the body surface of plants or other benthic animals. Most benthic animals live in the sediment for a long time and have the characteristics of strong regionality and weak migration ability. They usually have little ability to avoid environmental pollution and changes, and the destruction and reconstruction of their communities takes a relatively long time; Larger and easier to identify; at the same time, different species of benthic animals have different adaptability to environmental conditions and tolerance and sensitivity to unf...
