SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Placopecten magellanicus

SPECIES NAME(s)

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).


ANALYSIS

Strengths
  • For Georges Bank ‘A’, which accounts for >70% off the offshore scallop fishery landings in the Canadian Maritimes, annual TACs are set based on an analytical assessment model that incorporates annual survey data and commercial fisheries data. DFO’s Precautionary Approach ensures that the Management decisions based on this advice maintain the resource in Georges Bank ‘A’ in the ‘Healthy Zone’ (DFO 2018; Knapman et al. 2020).
