Acadian redfish, Ocean perch, redfish
Acadian redfish in the Gulf of St. Lawrence (unit 1) and the Laurentian Channel (unit 2) were previously assessed separately but from 2010 a joint assessment was conducted as there is evidence that the two units belong to the same biological unit. However uncertainty remains as to exchange with adjacent units (Valentin et al, 2005).Historically, Acadian redfish in the Gulf of St. Lawrence (Unit 1) and the Laurentian Channel (Unit 2) were assessed separately but from 2010 a single assessment was conducted following evidence that fish from these two units belong to the same biological stock. Units 1 and 2 are two of nine NW Atlantic redfish management areas. Detailed genetic studies have shown a complex sub-stock structure for this species, with components often referred to as ecotypes (Valentin et al. 2014, Benestan et al. 2021). Unit 1 and Unit 2 Acadian redfish remain assessed and managed as a single stock.
