Interactions between seabirds and deep water hake trawl gear: an assessment of impacts in South African waters 2004/05
Abstract: This study estimates the mortality of seabirds in the South African deep water hake ... . Mortalities were greater in winter, when more birds attended fishing vessels, and most occurred during dumping ... average mortality rates were 0.56 (0.32-0.82) birds killed per hour during dumping in winter, 0.21 (0.07 ... -0.38) during dumping in summer, 0.09 (0.02- 0.19) when not dumping in winter, and 0.00 (–) when not ...

Discussion on recent results from an integrated assessment of Antarctic krill (Euphausia superba) in Subarea 48.1
from three of the models provide a robust picture of changes in the krill population. An annual model ... surveys estimated similar absolute biomasses and changes in biomass. A seasonal model estimated similar ... changes in biomass but lower absolute biomasses than the two annual models. A monthly model estimated ... different changes in biomass but predicted absolute biomasses that were similar to those from the seasonal ...
