WG-IMAF-09

CCAMLR Members monitor beached debris, entanglement of marine mammals, marine debris associated with seabird colonies and animals contaminated with hydrocarbons at a number of sites, primarily in Area 48. Overall non-fishing debris items (mostly packaging items) have made up the majority of debris reported from monitoring sites. Relatively large amounts of fishing items have been reported at Read More

Surveys of beached marine debris at Bird Island, South Georgia recorded a total of 142, 96 and 148 items during summer 2007/08 (October 2007 to March 2008), winter 2008 (April to September) and summer 2008/09 (October 2008 to March 2009). Surveys at Signy Island, South Orkneys recorded a total of 113 items during summer 2008/09 (November 2008 to February 2009). Plastic, trawl webbing and ropes Read More

Fisheries are increasingly adopting ecosystem approaches to better manage impacts on non-target species. Although deliberate dumping of plastics at sea is banned, not all fisheries legislation prohibits discarding of gear (hooks and line) in offal, and compliance is often unknown. Analysis of a 16 year dataset collected at Bird Island indicated that the amount of gear found in association with Read More

For operational reasons it would be more convenient to extend the 48.3 fishing season into April rather than into September. A proposal is developed to experimentally allow incremental extensions into April, accompanied by a bird bycatch limit, starting with an allowance for all vessels having full compliance with CM 25-02 in 2009 to fish from 26 April 2010 in the 2009/2010 fishing season.

Within the Crozet Islands Exclusive Economic Zone (EEZ), the Patagonian toothfish longline fishery is exposed to high levels of depredation by killer and sperm whales. In this context, this study (i) provides estimations of annual depredation levels on a 5-years period (2003-2008), (ii) proposes operational measures to reduce depredation levels using the current longline fishing technique.

Three GLS datasets were added to the BirdLife Global Procellariform Tracking Database in 2008. 

In recent years there has been an increased focus on reducing ‘residual’ seabird captures that occur during hauling in CCAMLR longline fisheries. Haul captures were first recognised by CCAMLR as a problem as early as 1994/95 when steps were taken to reduce the attraction of birds to vessels during the hauling process.  Since 2003 increased efforts have been made to improve the design and Read More

Seabird mortality levels caused by net entanglement in the icefish trawl fishery in Subarea 48.3 became a concern in the late 1990s. At this time there was little knowledge on how to mitigate such mortality. As an interim measures a vessel specific 20‐bird mortality threshold was introduced for Subarea 48.3 in 2001. This provided a strong commercial incentive for industry to develop measures  Read More

This paper documents recent and ongoing developments in New Zealand’s Exclusive Economic Zone that are relevant to the work of the IMAF working group. The bycatch of seabirds by fisheries within New Zealand’s EEZ in recent years that either breed or forage within the CCAMLR convention area (Convention Area seabirds) is detailed. This paper contains description of the recent and ongoing seabird Read More

The Agreement on the Conservation of Albatrosses and Petrels held the Third Session of its Meeting of the Parties from 27 April – 1 May 2009. Key outcomes of relevance to the Ad Hoc WG-IMAF were the adoption of the Advisory Committee’s Work Programme for 2010-2012 and the granting of approval for the ACAP Secretariat to enter into a Memorandum of Understanding with CCAMLR. The proposed MoU has Read More
