Résumé:

During its 2022 meeting, WG-IMAF noted the need to develop a data collection template and accompanying instructions for krill trawling vessels to report standardised data in the event of a whale mortality event. Independent of WG-IMAF discussions, the US Marine Mammal Commission generously provided to IWC-SC a potential data collection form for recording information on whale Read More

Résumé:

The Agreement on the Conservation of Albatrosses and Petrels (ACAP) has identified nine Priority Populations for conservation on which advocacy and other activities might focus. Here we present the results of an analysis of global political responsibility for the seven ACAP Priority Populations of relevance for CCAMLR, based on tracking data, that identifies the Read More

Résumé:

CCAMLR achieved a significant progress in addressing seabird bycatch in its longline fisheries, model that is followed in a range of fisheries worldwide. New actual and potential challenges and opportunities are changing the scenario of conservation issues and strategies to address incidental mortality, in particular for Read More

Résumé:

CCAMLR conservation measures for seabird bycatch mitigation in longline and trawl fishing in the Convention Area seek to minimise artificial light at night. But advice is not provided about how minimisation of any light pollution is to be achieved. Light pollution guidelines for wildlife, and mitigation standards for reducing light-induced vessel strikes of Read More

Résumé:

For vulnerable marine megafauna, understanding migratory connectivity and its implications for spatiotemporal overlap with threats is crucial for developing targeted management strategies. Amongst their most severe threats is incidental mortality (bycatch) in fisheries. However, few studies have examined year-round co-occurrence of populations and the Read More

Résumé:

During its 2022 meeting, the Working Group on Incidental Mortality Associated with Fishing (WG-IMAF) reviewed results of extrapolations of the number of warp strike incidents, as informed by the protocols for SISO observers in CCAMLR trawl fisheries requiring one 15 min observation period per vessel per day. As a result, WG-IMAF noted that the recommended one 15-minute warp strike observation Read More

Résumé:

1. Antarctic fur seals (Arctocephalus gazella) are an iconic marine mammal, an important component of Antarctic ecosystems, and a key indicator species for regional fisheries management. Recent studies have demonstrated A. gazella is composed of at least four distinct subpopulations, including one breeding on the South Shetland Islands. These South Shetland Read More
