Temperature-dependent reproduction and survival of Gyrodactylus salaris Malmberg, 1957 (Platyhelminthes: Monogenea) on Atlantic salmon ( Salmo salar L.)
SUMMARY The relationship of survival and reproduction of Gyrodactylus salaris Malmberg on the Atlantic salmon ( Salmo salar ) to water temperature (2·5–19·0 °C), was studied on the basis of temporal sequence of births and age at death of individual parasites on isolated salmon, and of infrapopulatio...
