Effect of Triaenophorus on Growth of two Fishes

Abstract

Whitefish parasitized with plerocercoids of Triaenophorus crassus are slightly shorter and considerably lighter than non-parasitized fish of the same age. Heavily parasitized tullibee (Leucichthys sps.) grow slightly more slowly than lightly parasitized fish.Whitefish are more affected by the parasites than tullibee, a fact which favours the argument that Leucichthys sps. are the more natural hosts for T. crassus.
