Abstract

Estimates of various life history parameters of sympatric populations of Ammodytes dubius and A. americanus from coastal waters of Newfoundland are presented for the first time. Significant differences between the two species of sand lances were evident for length-weight and age-weight relationships. In addition, A. americanus tended to have a slightly earlier spawning season, and matured at a slightly earlier age than A. dubius. Similarities in these vital rates were noted between A. americanus populations in Newfoundland coastal waters and those in New England waters. Likewise, populations of A. dubius from coastal Newfoundland waters had similar vital rates as those published for A. dubiuspopulations on the Grand Banks.
