Distribution, abundance, and preliminary estimates of production potential for the ocean quahaug (Arctica islandica) and Stimpson's surf clam (Spisula polynyma) on the Scotian Shelf / by T.W. Rowell and...: Fs70-8/86-56E-PDF
"Both the ocean quahaug (Arctica islandica) and Stimpson's surf clam (Spisula polynyma) resources of the Scotian Shelf appear to have potential for future exploitation. Six areas, totalling 2,452 km 2 , on Western and Sable Island Banks had a mean quahaug density of 0.256 kg/m 2 and a biomass on the order of 628 kilotons. Additionally, two areas, totalling 2,298 km 2 , on Banquereau Bank had a mean surf clam density of 0.244 kg/m 2 and a biomass on the order of 561 kilotons. Mean densities of ocean quahaugs and Stimpson's surf clams on the remaining areas of these banks were 0.042 and 0.034 kg/m 2 respectively and unlikely to support commercial activity. Using instantaneous natural mortality (M) rates of 0.020 and 0.043 for ocean quahaugs, a MSY of between 6,277--13,495 t was derived. For Stimpson's surf clam a MSY of 16,821 t was derived using M= 0.060"--Abstract.
