THE EFFECT OF LONG-TERM, LOW-LEVEL EUBOTHRIUM SP (CESTODA, PSEUDOPHYLLIDEA) INFECTION ON GROWTH IN FARMED SALMON (SALMO-SALAR L)

Loss of potential growth in farmed salmon with persistent low-grade infection of Eubothrium sp. is shown to be approximately 450 g per fish for females and 800 g per fish for males. The systematics of Eubothrium sp. are discussed with regard to Eubothrium crassum and its sibling species in relation to salmon farming. The epidemiological implications of the infections are discussed with regard to aquaculture.
