Summary:The occurrence of Caligus elongatus on Atlantic salmon (Salmo salar) cultured in marine waters in the Passamaquoddy Bay region of the lower Bay of Fundy is reported. Two size classes of cultured salmon (smolts and market size) were examined. Prevalence of C. elongatus was 54.5% on market fish and 54.7% on smolts. Intensities of infection for market fish and smolts were recorded as 2.41 and 2.58, respectively. Overall sex ratio of adult C. elongatus on infected salmon was 1:1.4 females to males; mean number of eggs per gravid female C. elongatus was 169.
