American sea scallop
Genetic differentiation between banks is considered as weak due to gene flow but there are recruitment and growth regional variations that support the consideration of distinct assessment and management units (Caddy et al. 2010): Eastern Scotian Shelf (SFA 25), St. Pierre Bank (SFA 10, 11, 12), Browns and German Banks (SFA 26) and Eastern Georges Bank (SFA 27A). SFA 27 was divided into 'A' and 'B' in 1998 (each with different TACs) due to differences in productivity and historical fishing patterns (DFO 2018).
