Catch and effort data for Fantail Darter.
Description
Catch and effort data for Fantail Darter (Etheostoma flabellare) from seven removal events conducted by Mahon (1980).
Format
A data frame with 7 observations on the following 2 variables.
- catch
Catch of Fantail Darter.
- effort
Constant electrofishing effort.
Details
Catch (number of fish) was recorded. Effort was a constant amount of electrofishing for each sampling event and is, thus, entered as a constant value of 1.
These data are used in many publications because the stream section was rotenoned following the removal surveys to determine a known population size of 1151 individuals.
