The variation in egg size present in the eggs of Arctic charr, Salvelinus alpinus , was significant for the survival and growth of newly hatched alevins. Alevins from large eggs were larger, grew more quickly, and suffered less initial mortality than alevins from small eggs. The yolk sac was proportionately larger in alevins from large eggs. The largest eggs produced a relatively high proportion of abnormal alevins.
