Abstract— The wintering success of young‐of‐the‐year pikeperches (Stizostedion lucioperca) was examined in the laboratory during the winter of 1993‐1994. From September to November half the fishes were offered artificial fishfood; the others received plankton with river water. Pikeperch did not eat the fishfood properly, and poorer condition of the smallest fish fed artificially was reflected in a lower amount of lipid in the whole fish at the beginning of the experiment in November. The autumnal diet played an important role in determining the wintering success even when the effect of size was removed. In contrast, feeding during the experiment did not affect survival. However, feeding fishes had more lipid at the end of the experiment in April than starved ones and their protein content also increased during the winter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
