The maternal effects on Pikeperch ( <i>Sander lucioperca</i> ) larvae depend on temperature

We studied the influences of female pikeperch (Sander lucioperca) length and growth (i.e., maternal effects) on hatched starved larvae as well larval starvation resistance in two different temperature conditions (mean temperatures 13.2 17.9°C). The data included fertilised eggs reared from 21 individuals caught during spawning season eutrophic Lake Pyhäjärvi Finland. hatching was dependent size but also water potential energy had invested reproduction. Maternal effects seemed to influence timing growth, that were large at grew less mere yolk sac reserves, vice versa. Female a positive effect only under cold conditions. results suggest higher might reduce advantage females get for resistance.
