"With the expansion of the West Greenland salmon fishery in the mid 1960s came the need for an accurate assessment of the effects of this fishery on North American stocks of salmon. A first step in this assessment has been to determine the proportion of the West Greenland salmon that originate in North American rivers. One approach to this problem is based on observed differences between North American and European salmon in serum transferrin phenotypes (Payne 1973). … Payne (1973) developed an estimator of the number of North American salmon using the observed transferrin phenotypes and the assumption that these phenotypes are in genetic equilibrium (distributed according to the Hardy-Weinberg equation) in the American component of the West Greenland stock complex. … It is the thesis of this paper that Payne's estimator has a persistent negative bias, and therefore, that the tendency in the past will have been to underestimate the proportion of North American salmon in the West Greenland aggregate."--Introduction, pages [1]-2. gccst Fisheries gccst Salt water fish Canada.
