Methods for assessing social status in Arctic charr
The aggression index is a more reliable method for assessing the social status of Arctic charr Salvelinus alpinus held in small groups, than is food intake or position relative to a defensible food resource. However, care must be taken when assigning rank, as all three of these commonly used methods...

However, care must be taken when assigning rank, as all three of these commonly used methods can result in different social ranks for an individual fish. |
