Electrofishing Data from Nova Scotian Rivers (SFA 18A, 18B)

PURPOSE:

To track juvenile Atlantic salmon densities.

DESCRIPTION:

Indices of freshwater production are derived annually from electrofishing surveys in the rivers of Nova Scotia flowing into the Gulf of St. Lawrence. Fixed site sampling for juvenile salmon has been conducted most consistently since the mid-1980s for these rivers. Juvenile salmon abundances at sites, in terms of number of fish per habitat area sampled by age or size group (densities), are obtained using successive removal sampling or catch per unit effort sampling calibrated to densities. Sampling intensities vary among years and among rivers.

PARAMETERS COLLECTED:

distribution (ecological); species counts (ecological); point (spatial)

USE LIMITATION:

To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.
