3. Analysis of haul data from the South Georgia krill fishery

   Paper Title:  Analysis of haul data from the South Georgia krill fishery Abstract / Description ... :  Data from individual hauls carried out by vessels operating in the South Georgia krill fishery between ... 1994 and 1996 were examined and a range of descriptive measurements reflecting the fishery operation ... were produced. The measurements emphasise that the krill fishery at South Georgia was geographically ... tightly clustered towards the end of the season. After each haul is complete, the distance to the next ... at South Georgia occurs during the austral winter and spans the end of one CCAMLR reporting year ... and the beginning of the next. Therefore to aid clarity in this study, data have been analysed by ... fish; fishing end time: the time at which hauling started and the net stopped fishing; * haul end ...
