Fishing behaviour of Chinese krill fishing fleet
Abstract: Understanding the fishing behavior of a kind of fishery is a very important part of developing and managing this fishery comprehensively. In this paper, based on the random walk model, the relationship between distance and frequency distribution of the adjacent krill fishing positions

Linking acoustic scattering coefficient to krill fishery data: feasibility of estimating krill abundance using fishing survey
Abstract: Antarctic krill (Euphausia superba Dana) is a key species in the Southern Ocean ecosystems and supports different levels of predators. It is also an important economic species for Antarctic fisheries. In this paper, using the multi-frequency acoustic data and the fishery data, the

Increasing abundance of Type A killer whales (Orcinus orca) in the coastal waters around the Antarctic Peninsula
Abstract: The physical marine environment around the Antarctic Peninsula (AP) is rapidly changing and we need to understand the impact on marine ecosystems. A diverse community of killer whales (Orcinus orca; Types B1, B2 and A) are important top predators around the AP, but there are currently no

Estimating nest-level phenology and reproductive success of colonial seabirds using time-lapse cameras
Abstract: We wish to draw the attention of Members to an online application of the R code published in the attached paper. The web-based app ‘photoR’ (https://jefferson.shinyapps.io/photor2) implements the methods of the paper and provides summary outputs for direct input to CEMP A6b and A9

Impacts of rising sea temperature on krill increase risks for predators in the Scotia Sea
Abstract: Climate change is a threat to marine ecosystems and the services they provide, and reducing fishing pressure is one option for mitigating the overall consequences for marine biota. We used a minimally realistic ecosystem model to examine how projected effects of ocean warming on the

The winter pack-ice zone provides a sheltered but food-poor habitat for larval Antarctic krill
Abstract: A dominant Antarctic ecological paradigm suggests that winter sea ice is generally the main feeding ground for krill larvae. Observations from our winter cruise to the southwest Atlantic sector of the Southern Ocean contradict this view and present the first evidence that the pack-ice

Competition-induced starvation drives large-scale population cycles in Antarctic krill
Abstract: Antarctic krill (Euphausia superba)—one of the most abundant animal species on Earth—exhibits a five to six year population cycle, with oscillations in biomass exceeding one order of magnitude. Previous studies have postulated that the krill cycle is induced by periodic climatological

Spatial and temporal distribution patterns of acoustic backscatter in the New Zealand sector of the Southern Ocean
Abstract: Mid-trophic level organisms (MTLO) of open-ocean marine ecosystems play a key role linking primary and tertiary consumers. Despite their importance, characterisation of MTLO is limited due to sampling difficulty, and is largely obtained through active acoustics. Acoustic data collected

Predicting distribution and relative abundance of mid-trophic level organisms using oceanographic parameters and acoustic backscatter
Abstract: Data on the distribution and abundance of mid-trophic level organisms (MTLOs) in the pelagic open-ocean ecosystem are normally sparse or absent. Consequently, ecosystem models are limited in their ability to support decision-making for issues ranging from fisheries management to
