Effect of a shore-based sampling programme on Notothenia coriiceps populations
The effect of an intensive sampling programme on an inshore population of Notothenia coriiceps was studied at Potter Cove, South Shetland islands, by comparing catch data taken in successive summers of 1992/93 to 1994/95 at one specific zone (site 1) with those taken in the 1994/95 summer at two clo...
