Vertebral Numbers in Atlantic cod, Gadus morhua , of the Newfoundland and Adjacent Areas, 1947-71, and Their use for Delineating Cod Stocks

Abstract

A total of 416 cod vertebral samples collected from the Newfoundland and adjacent areas during 1947-71, are analyzed in relation to their use for delineating the cod stocks of the region. Differences greater than two vertebrae were found between the highest and lowest vertebral means for different stocks. The overall vertebral mean for females exceeded that for males by 0.10.
