Summary of holdings of Patagonian toothfish (Dissostichus eleginoides) otoliths and size-at-age estimates from Heard and McDonald Islands (Division 58.5.2)
Abstract: Scientific observers aboard vessels in the Australian fisheries in 58.5.2 have collected Dissostichus eleginoides otoliths since the fishery commenced in the 1996/97 season. This program has yielded data which has assisted with understanding age structure and growth rates of toothfish in

Integrated weight longlines: potential for reduction of skate by catch in demersal longline fisheries
Abstract: We analyzed data collected during 2005 seabird mitigation experiments on integrated weight longlines (IW) in a demersal longline fishery for effects on skate bycatch. Trials took place on two vessels targeting Pacific cod (Gadus macrocephalus) over a five-month period in the Bering Sea,
