The length‐weight relationship for Ammodytes americanus sampled from the New England coast was determined and compared to the relationships for five other sand lance species available from the literature. Postspawning A. americanus females weighed up to 45% less than prespawning females of the same length. The relationship between fecundity (F, number of eggs/female) and fork length (L, cm) is log 10 F = 3.857 log 10 L ‐ 0.484. Ovarian egg diameters were unimodal which suggests once‐a‐year spawning for this species.
