Title at head of French abstract: Documentation du comportement de nettoyage de la tanche-tautogue (Tautogolabrus adspersus) dans les réservoirs contenant des saumoneaux de l'Atlantique (Salmo salar) infestés par le pou du poisson (Lepeophtheirus salmonis) [Ottawa] : Fisheries and Oceans Canada, c2016. vi, 11 p. : ill.

The delousing efficiency of cunner (Tautogolabrus adspersus) against Lepeophtheirus salmonis infecting Atlantic salmon (Salmo salar) is documented in a tank study through the assessment of cunner behavioural responses. Lice counts are reduced by 89.3% in salmon smolts after 78 hours residence with cunners (2 tanks; cunner to salmon ratio of 1:10); as compared to the control tank without cunners that did not show a significant reduction of lice over the same time period (p=0.275). Video data show a significant increase of cunner activity (salmon chasing, and lice picking) with cohabitation time with salmon. This study confirms the lice cleaning efficiency of cunner through the documentation of behavioural responses in a tank study. Findings suggest that cleaning is likely an opportunistic behaviour not occurring naturally in cunner, but easily acquired through cohabitation with salmon. gccst Salt water fish gccst Parasites Costa, I.
