Method for monitoring and evaluating environment quality of Laizhou Bay marine ranching on basis of living body response

Abstract

The invention discloses a method for monitoring and evaluating environment quality of Laizhou Bay marine ranching on the basis of living body response. Four key species of different living habits areselected as biological indicators from Laizhou Bay marine ranching, one biomarker of gene expression or enzyme activity levels is selected from target tissue of each biological indicator, various types of biomarker data are integrated by using a multi-biomarker pollution index MPI method, and monitoring and evaluation on biomarkers of multiple species at multiple levels are achieved. Defects of indirectness, secondary pollution and the like of conventional chemical detection can be overcome; hysteresis of biological community diversity detection can be overcome; and the method is an effectiveand sensitive biological monitoring method, in addition, the method is low in professional requirement on operators, rapid in detection speed and low in cost, and technical support can be provided forearly warning and biological monitoring system establishment for marine ranching environments.

Description

technical field [0001] The invention belongs to the technical field of biological monitoring, relates to a cross-species monitoring technology for monitoring the environmental quality of marine pastures, and in particular relates to a method for evaluating the environmental quality of Laizhou Bay marine pastures based on biological response monitoring. Background technique [0002] Marine ranching is a new type of modern marine fishery production mode, and a new form of marine fishery that realizes the integration of land and sea and the integration of three industries. It is of great significance to ensuring marine food supply and ecological security. From the central to local governments, the construction of marine ranches is highly valued. Marine ranches are mostly built in the offshore areas that are seriously affected by land-based input. The 2018 China Marine Ecological Environment Bulletin shows that the pollution of some coastal areas is still serious. Therefore, ecol...

Problems solved by technology

[0003] Ecological environment monitoring mainly includes physical and chemical monitoring and biological monitoring, but physical and chemical monitoring cannot cover unknown risk substances, nor can it evaluate the biological effects of pollutants. Therefore, biological monitoring is more important for marine ranches whose main service function is to provide high-quality aquatic products. important

However, there are still some problems that need to be solved urgently in the existing biological monitoring. For example, biological monitoring indicators such as community diversity and biological pollutant levels are lagging behind in indicating the environment, and cannot meet the needs of marine ranching management. In addition, the current marine ranching The current biological monitoring methods focus on the biome level, and an earlier early warning monitoring technology has not been established; therefore, it is urgent to develop a new type of pasture environmental biological monitoring technology at this stage
