Long-term changes in the size composition of fjord Notothenia rossii, Gobionotothen gibberifrons and Notothenia coriiceps at Potter Cove, after the 1978–1980 fishery in the area
the impact of the fishery in the area in 1978-80, allowed the comparison of the variations in mean annual ... for the period 1983- 1991/2 is consistent with the increase in mean size observed between 1983 and 1986 ... with the consequent reduction in mean size. The above interpretation is supported by the length distributions observed ... the densities, mean sizes and abundances do not depend on a single forcing event but on several interacting ...
