Maturation, Fecundity, and Intertidal Spawning of Pacific Sand Lance in the Northern Gulf of Alaska

Journal of Fish Biology, 1999
Pacific sand lance Ammodytes hexapterus in Kachemak Bay, Alaska, showed no sexual dimorphism in length‐to‐weight (gonad‐free) ratio or length‐at‐age relationship. Most matured in their second year, males earlier in the season than females, but females (31%) attained a higher gonadosomatic index than males (21%).

Forage fish are primary prey for seabirds, fish and marine mammals. Contaminant transfer and biomagnification of the toxic compounds measured in this study likely contribute to elevated levels in Puget Sound, Washington, salmon and killer whale tissues that could be sufficiently high to elicit adverse effects and hamper population recovery efforts ...
