Relevé acoustique et aux filets maillants expérimentaux sur les frayères locales de hareng de printemps

Since 2002, similar projects have been conducted in the southern Gulf of St. Lawrence (NAFO area 4T) on fall spawning herring. The strength of age-classes entering the fishery is important because the numbers of new age-classes entering the fishery have the most influence on changes in determining the recruitment and changes in size at maturity, as well as providing valuable information to set appropriate fishing levels from year to year. Conducting this study on each major spring herring spawning area in the southern Gulf of St. Lawrence will provide a better understanding of the zonal abundance of fish in the region, and improve the spring stock assessment.
