Description:

Encrusting "Balanus hesperius laevidomus" and "B. crenatus" on carapaces of Gulf of Alaska "Chionoecetes bairdi" were examined to determine if barnacle age could be used to provide a qualitative estimate of tanner crab intermolt periods. From a quarter to a half of harvested male crabs had barnacles on their carapaces; the age and basal diameter of the largest barnacles on each crab were determined. The prevalence of newly settled barnacles, and individuals that had settled the previous year, on harvested "C. bairdi" suggests that most crabs molted within the expected period. The results of this study suggest that for some Gulf of Alaska areas, barnacle age can aid in estimating tanner crab intermolt periods.
