Gonadosomatic index (GSI) and mean body length of mature females, and egg mass and egg numbers vs. body mass of the three coregonid eco-species.

<p>A: Mean fish length and gonadosomatic index (GSI), with error bars showing 1 SE. DR = densely-rakered whitefish, SR = sparsely-rakered whitefish. The difference in GSI was significant between all three ecospecies (p<0.001). B: Egg mass vs. body mass. Mean egg mass per female fish was modelled with the statistical model = log(Egg mass) x Ecospecies, model predictions indicated by lines. Confer text for statistical results. C: Egg numbers vs. body mass.
