Southern Gulf of St. Lawrence (NAFO Division 4T) Atlantic Herring Experimental Gillnet Surveys
PURPOSE:
To provide demographic parameters and relative indices of abundance for Atlantic herring in NAFO Division 4T.
DESCRIPTION:
The experimental gillnet survey is conducted in collaboration with Atlantic herring harvesters and uses standardized multi-mesh gillnets. Gillnets are set on spawning grounds in the spring and fall. Data (fish and sample) are collected to provide: (1) relative age-disaggregated indices of abundance, (2) an indicator of relative changes in fishery selectivity over time, and (3) information on the demographic composition of herring on the spawning grounds.
PARAMETERS COLLECTED:
Sample: sample location; sample weight; mesh size; length frequency
Biological: length; weight; gonad weight; maturity stage (biological); sex (biological); ring count (biological)
USE LIMITATION:
To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.
