WG-EMM-2025

The  scientific and legal aspects of revising the Krill Fisheries Management Approach (KFMA) and establishing the Domain 1 MPA are discussed. . It stresses that proposals to harmonise the D1MPA and KFMA to conserve and
manage krill resources in Subarea 48.1 require scientific and legal justification.

This content is part of the manuscript “Adjusting management of the Antarctic krill
fishery to the challenges of the 21st Century”, which is at present under review in PNAS.
Climate change is threatening krill populations and their predators, while current catch
limits do not take into account climate variability or krill population dynamics. In 2024,
CCAMLR was unable to renew its Read More

This report summarizes the krill fishing activities conducted by Korean-flagged vessels within the CCAMLR Convention Area from 2020 to 2024, with a particular focus on fishing effort, spatial and temporal patterns, catch per unit effort (CPUE), and the composition of non-target species (bycatch). A total of 14,460 hauls were recorded during this period, yielding annual krill Read More

The diet of non-breeding male Antarctic fur seals Arctocephalus gazella was investigated at four localities in the South Shetland Islands (Deception Island, Potter Peninsula, Duthoit Point and Harmony Point), through analyses of 1254 scats collected from 1995 to 2004. The Antarctic krill, fish and penguins were the main prey items at the four study locations. Antarctic Read More

Incidental mortality of non-target species in fisheries (bycatch) is driving population declines of seabirds globally. For wandering albatross Diomedea exulans populations in the Southern Ocean, current fisheries threats are primarily from pelagic longline operations, and to a lesser extent demersal longline and trawl Read More

The Pine Island Glacier Special Area for Scientific Study (SASS) was designated in 2019 under the provisions of CM 24-04, and updated in 2021 and 2023. This precautionary protection aimed to allow for research to be undertaken in the absence of other human activities, recognising the potential scientific importance of marine habitats exposed by glacial retreat. Pine Island Glacier has Read More

A VME is proposed herein based on high abundances of VME indicator taxa that fall within the range of previously registered VMEs. The site is off the east coast of Cuverville Island, Errera Channel, Western Antarctic Peninsula. Video imagery was taken via ROV deployed by M/Y Legend. Data on the relative percent cover of all VME indicator taxa was sourced and analysed in the same manner Read More

The Antarctic Peninsula is increasingly impacted by both global pollution transport and local human activities. This study proposes a standardized, non-invasive framework for monitoring environmental contaminants - specifically heavy metals (Hg, Pb, Cd, As) and phenolic compounds (BPA, 4-NP, 4-t-OP) - using Pygoscelis penguins as sentinel species.

Over the last decade significant evidence has shown that Antarctic marginal seas have been impacted by the effects of global warming, which has motivated more ocean research in those regions. In 2019, a national Antarctic Science Platform was introduced to support climate-focused Antarctic research. In addition, the Ross Sea Marine Protected Area requires underpinning research activity.

The standard method for calculating Antarctic krill biomass relies on hydroacoustic survey data and incorporates krill body length data collected concurrently. Traditional scientific acoustic surveys involve manually measuring the body lengths of individual krill caught using fine- meshed nets or trawls along acoustic transects. This work is resource-demanding and could Read More

Antarctic krill (Euphausia superba Dana) is a key species of the Southern Ocean ecosystem, immensely abundant and targeted by the krill fishery. For their sustainable management, krill distribution and biomass estimates are required, typically achieved through acoustic-trawl surveys. We explore how krill environmental DNA (eDNA) can contribute to our understanding or Antarctic krill Read More

This paper highlights the urgent need for coordinated surveillance, response, and policy action to address the spread of high-pathogenicity avian influenza (HPAI H5) in the Southern Ocean region. The recent incursion of HPAI into mainland Antarctica and associated mass mortality events among seabirds and marine mammals present a direct threat to the objectives of the Convention, particularly Read More

Bransfield Strait is an important spawning, feeding and overwintering ground for Antarctic krill. Increases in both the biomass of krill and the ice-free extent of the Strait makes this area of interest for krill fisheries. While krill are known to have access to food supplies beyond summer, lipid accumulation plays a pivotal role in their ability to survive the food-limited Read More

This paper provides details on proposed new separate C1 haul by haul forms for finfish and krill trawl fisheries and accompanying instructions for review by WG-SAM and WG-EMM. The forms incorporate recommended fields from WG-IMAF to clarify how incidental mortalities are reported on vessels.  

In this paper, the authors consider inter-vessel variability in the length composition of krill in catches from commercial vessels operated in local fishing grounds in Subarea 48.2 during March 2024. The authors obtained additional evidence that existing observation protocols   tend to under sample krill for different length groups especially recruitment groups, Read More
