Electronic Monitoring (EM) offers the potential to reduce CCAMLR scientific observer tasking onboard vessels, while improving data quality, increasing data collection and improving observer safety. Fisheries observers should be utilised to fulfil and integrate the reporting requirements carried out by EM on these vessels, using a holistic approach. In the mid to longer Read More

Here we outline a proposal for a workshop to enhance the CCAMLR Ecosystem Monitoring Programme (CEMP) based on recommendations arising from WG-EMM-2022.

Summary

Over the past years, the subject of whether there is a functional overlap between the krill fishery and pelagic krill predators has been discussed throughout the SC-CAMLR Working Groups. Specifically, these discussions centre around two key issues: a) whether there are potential interactions and competition between the krill fishery and krill-dependent predators during Read More

Among large cetaceans in the Southern Hemisphere, fin whales were the most heavily exploited in terms of numbers taken during the period of intense industrial whaling. Recent studies suggest that, whilst some humpback whale populations in the Southern Hemisphere have almost completely recovered to their estimated pre-whaling abundance, much less is known about the status of Southern Hemisphere Read More

This paper summarises data collected by Scheme of International Scientific Observation observers and vessels, of incidental interactions between fishing vessels, seabirds and marine mammals during fishing activities undertaken during the 2020 and 2021 seasons. The extrapolated total of 44 seabirds caught in 2020 is the lowest on record for CCAMLR fisheries. Three humpback whales were recorded Read More

Antarctic krill fishing started in the 1970s and has undergone a gradual increase in activity over recent decades. For the very first time, three incidental mortalities of humpback whales (Megaptera novaeangliae) were reported during the 2020-21 fishing season due to interactions with the fishing gear, and one more case was reported in the 2021-22 Read More

The incidental mortality (bycatch) of seabirds in longline and trawl fisheries continues to be a serious global concern, especially for threatened albatrosses and petrels, resulting in a Conservation Crisis being declared by the Agreement on the Conservation of Albatrosses and Petrels (ACAP) in 2019. There are currently 31 species listed in Annex 1 of the Agreement.  Of the 22 species of Read More

This paper summarises data collected by Scheme of International Scientific Observation observers and vessels reporting incidental interactions between fishing vessels, seabirds and marine mammals during fishing activities undertaken during the 2022 season. The extrapolated total of 15 seabirds caught as of 12 September 2022 is the lowest on record. One humpback whale was recorded Read More

In this paper we share the New Zealand experience to reduce the observed New Zealand Sea Lion bycatch in the Southern Squid Fisheries. Some of the experience gained during the design, development and implementation of the marine mammal mitigation devices in this fishery could be explored for relevance to the CCAMLR krill fisheries. The New Zealand Sea Lion/Pakake/Whakahao ( Read More

In 1991, CCAMLR adopted Conservation Measure (CM) 25-03, which prohibits the use of net monitoring cables in the Convention Area following concerns over potential seabird mortalities, it applies to all trawling techniques. Technology has developed since the introduction of this CM and the Read More

This report presents the preliminary results of the 2021/22 season net monitoring cable (NMC) trials, representing the third season these trials have been undertaken. The rationale behind these trials has been presented in WG-FSA-2021/13 which outlined the reasons behind the original prohibition of NMCs in Conservation Measure (CM) 25-03 Read More

1. The impact of industrial fisheries on marine biodiversity is conspicuous in large pelagic vertebrate's fisheries bycatch. In seabirds, this led to the decline of many populations since the 1980s following the rise of global fishing effort. Bycatch

mitigation measures were implemented since the 2000s, but their effects on the concerned seabird populations remain poorly quantified and Read More
