Geographical size differences in Canadian offshore lobsters / A.B. Stasko and R.W. Pye. : Fs70-8/80-57E-PDF

"The median sizes of lobsters trapped on Truxton Swell and SW Browns Bank were smaller than those SE of Browns and on Georges Bank. Such differences cannot be attributed to fishing pressure, which has been light on Truxton Swell compared to SE Browns and Georges Bank. It is hypothesized that the offshore lobsters are derived from SW Nova Scotia inshore animals some of which at maturity move offshore. A gradation of sizes from smaller to larger is also noted from the canyons off New York to eastern Georges Bank, suggesting a similar outward movement of lobsters along Georges Bank from east to west"--Abstract.
