Established link between individual growth and puberty in sibling groups of salmon

Monitoring growth performance and age at puberty in large groups of individually tagged salmon at different sites revealed that the bigger individuals with high condition factor around the time of winter solstice had a much higher likelihood of early maturation than their smaller and leaner siblings. This clearly suggests a link to body size, growth and adiposity for recruitment into puberty. However, restricted feeding prior to winter solstice has less effect than expected on age at puberty when studied on 3 sibling groups with individually tagged salmon in sea cages. This may imply that other factors than growth and adiposity modulates the outcome of a certain treatment.
