Experimental infections with Lepeophtheirus salmonis (Krøyer) were established on threespine sticklebacks, Gasterosteus aculeatus L., juvenile pink, Oncorhynchus gorbuscha (Walbaum), and chum, Oncorhynchus keta (Walbaum), salmon. The prevalence and abundance of infections were initially higher on sticklebacks than on either salmon species. The initial prevalence and intensity of infections on chum salmon were higher than those on pink salmon, and declined on both species during louse development. The rate of parasite development to adult stages was similar on all species although development beyond the preadult stage was not observed on sticklebacks. These results confirm previous field observations on the occurrence and development of L. salmonis on threespine sticklebacks.
