PURPOSE:
To monitor juvenile Atlantic salmon densities over time.
DESCRIPTION:
Indices of freshwater production are derived annually from electrofishing surveys in Southeast New Brunswick. Juvenile Atlantic salmon abundances at sites, divided by age or size group and reported in terms of number of fish per habitat area sampled (density), are obtained using successive removal sampling or catch per unit effort sampling (which is calibrated using successive removal sampling data). Sampling intensities vary among years and among rivers.
This dataset comprises raw data on all fish captured and effort invested in the course of monitoring juvenile Atlantic salmon in Southeast, New Brunswick, from 1974 to 2024. Sampling was focused on habitat suitable for Atlantic salmon, and capture of any other species was incidental.
PARAMETERS COLLECTED:
Distribution (ecological); species counts (ecological); fish lengths (biological); fish weights (biological); point (spatial).
USE LIMITATION:
To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.
