Estuary Fish Inventory Network (EFIN)

Since 2009, annual monitoring of the estuary fish population has taken place at four different experimental fishing sites located on both the north and south shores. Two of these stations are located in the middle estuary, at Rivière-Ouelle and St. Irenaeus, the other two in the fluvial estuary in Cap-Santé and St. Nicolas. All sampling operations of the St. Nicolas station fall under the responsibility of the Aquarium du Québec. The St. Lawrence Estuary Fish Inventory Network provides an updated picture of the dynamics of fish populations encountered in the fluvial and middle estuaries. These official data were produced as part of the St. Lawrence Action Plan 2011-2026.For more information, please see the data context.

Parameters: presence / absence, individual count.

Access the data in the BIODIVERSITY application.
