Live and frozen freshwater zooplankton as alternative startfeeding diets for Atlantic salmon in trays
Six groups of Atlantic salmon (Salmo salar) fry were starfed with frozen Daphnia longispina, standard start food type EWOS or water with natural content of live zooplankton drained from the littoral zone in a coastal lake. In last five days, those fed live zooplankton were given additional food in t...

Six groups of Atlantic salmon (Salmo salar) fry were starfed with frozen Daphnia longispina, standard start food type EWOS or water with natural content of live zooplankton drained from the littoral zone in a coastal lake.

Fry fed live zooplankton had the highest activity but the natural species composition of the offer was not optimal for startfeeding. Survival was highest in the group fed frozen Daphnia whose tank had bottom drainage.
