Application of Species Cumulative Curve in the Investigation of Swimming Organisms in the Fishway of Cao’e River

View through CrossRef
Abstract Using the species cumulative curve (EstimateS) to analyze the monitored swimming biological data in the Cao’e River gate fishway, the results showed that as the number of sampling increased, the number of species gradually increased, and the cumulative curve rose sharply and then became smooth asymptote, indicating that the swimming organisms in the fishway were fully sampled; there were estimated to be 30 species of swimming organisms in the fishway, and 27 species were found in the actual sample survey, and the survey discovery rate reached 90%, and the sampling survey effect was good.
