Spatial distribution of Champsocephalus gunnari size and age are related with depth
all species resulted significantly associated with depth, positively in the case of C. gunnari and N ... . rossii and negatively for the remaining species. Less association with depth is observed in C. gunnari as ... the fish grow older, indicating that the spatial separation is controlled by depth. The accumulated ... catches of age I- present maximum difference with the older age classes at about 150 meters a result which ...
