Parentage and grandparentage assignment with known and unknown matings: application to Connecticut River Atlantic salmon restoration
Large-scale use of parentage assignment of stocked Connecticut River, U.S.A., Atlantic salmon (Salmo salar) fry to determine stocking tributary of emigrating smolts and returning adults requires both parentage assignment and grandparentage assignment. Using computer simulations, we explored the leve...

Large-scale use of parentage assignment of stocked Connecticut River, U.S.A., Atlantic salmon (Salmo salar) fry to determine stocking tributary of emigrating smolts and returning adults requires both parentage assignment and grandparentage assignment.
