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.

Topic(s)

• Population size
• Abundance
• Depletion methods
• Leslie method
• DeLury method
• Catchability
