摘要：

The effect of kinship on growth and growth variability was studied by rearing young-of-the-year Arctic charr in full-sibling, mixed-sibling or non-kin groups for 11 weeks. Both weight and length were found to be significantly greater among full-sibling v. mixed or non-kin groups. Also, variance in weight and length of the individuals within groups was found to be significantly lower in full-sibling v. mixed or non-kin groups. These data suggest that relatedness of group members has a significant effect on both the growth rate and variation in growth of juvenile Arctic charr.
