A method for establishing a standardized Anodonta dorsalis population dedicated to freshwater environmental monitoring

Abstract

The invention relates to a standardized anodonta woodiana population establishing method special for freshwater environment monitoring. The standardized anodonta woodiana population establishing method special for the freshwater environment monitoring is characterized by comprising the following steps of screening out anodonta woodiana for being used as parent anodonta woodiana for artificial breeding, and putting the selected anodonta woodiana into a culture pond to enable parasitic Glochidium to be cultured into juvenile anodonta woodiana; during the peak time of separation of the juvenile anodonta woodiana, transferring Pelteobagrus fulvidraco into the culture pond to enable the juvenile anodonta woodiana to be evenly distributed at the bottom of the pond so as to be cultured into young anodonta woodiana; transferring out the young anodonta woodiana from the culture pond and evenly placing the young anodonta woodiana into net cages; evenly distributing the net cages filled with the young anodonta woodiana into a culture pool for hanging culture until the young anodonta woodiana develops into offspring adult anodonta woodiana; transplanting the offspring adult anodonta woodiana into a natural water area of Taihu lake to serve as an experimental group and recapturing the offspring adult anodonta woodiana regularly, comparing the offspring adult anodonta woodiana with the offspring adult anodonta woodiana which is of the same batch, is still bred in an artificial breeding base and serves as a control group, and detecting the residual concentration of pollutant inside the offspring adult anodonta woodiana. The standardized anodonta woodiana population establishing method special for the freshwater environment monitoring enables the results of the water environment pollution monitoring to be more reliable and the comparability to be enhanced and is beneficial to monitoring the pollution level of the pollutant in the water environment more conveniently and rapidly.

Description

technical field [0001] The invention relates to a method for establishing a "standardized" Anodonta dorsalis population specially used for freshwater environment monitoring. Specifically, on the basis of learning from the breeding experience of freshwater bivalve pearl molluscs, the freshwater biological indicator clams independently screened are used. Species - Anodonta dorsalis ( Anodonta woodiana ), belongs to the technical field of biological monitoring environment through a series of artificial breeding and breeding condition optimization methods. Background technique [0002] Freshwater fishery is a very important part of my country's fishery industry. So far, the output of freshwater fishery aquatic products has accounted for 45% of my country's total. However, the freshwater ecological environment has become the most serious victim of water pollution. Therefore, it is necessary to strengthen the construction of an effective monitoring system for the ecological env...

Problems solved by technology

However, we have gradually noticed that the current research and application that only rely on the sampling of wild mussels in surveyed waters will be greatly limited (such as uneven sample sizes, samples cannot be collected in some waters to be surveyed, etc.
