Science Advisory Report 2011/042
An assessment of Sea Scallop on the St. Pierre Bank (Subdivision 3Ps)
- This is a pulse fishery with peaks in 1982, 1988 and 2004. Since 2005 landings have ranged between 300 t and 800 t (in 2010).
- A Canadian research survey in September 2010 resulted in a minimum dredgeable biomass estimate of 7,500 t, the lowest since 2005. The majority of the biomass is in the North bed.
- The biomass is currently predominated by a modal group of larger scallops (130 mm) in the North and South beds with a secondary mode of smaller recently-recruited scallops (90 mm ).
- Recruitment prospects are unknown.
- The reduction in biomass was mainly due to a dramatic reduction in the Middle bed after 2005. The Middle bed should be closed until a new recruitment pulse appears and contributes to the exploitable biomass.
- Meat quality in the larger-sized scallop in the North and South beds is expected to deteriorate and natural mortality to increase. Under this scenario the remaining exploitable biomass could be harvested.
