First published in 1993, The Biology of the Southern Ocean has been referred to as international research at its best and an invaluable reference. Drawing on the considerable volume of information published in the last ten years, this second edition retains the format that made the first edition a popular bestseller, while updating the information with the latest research results available. The book begins with a description of the physico-chemical environment and, in a logical sequence, covers phytoplankton and primary production, the sea ice microbial communities and the secondary consumers, the zooplankton. The author includes an extended chapter on the biology and ecology of Antarctic krill that highlights its central position in the Southern Ocean food web. A series of chapters consider the higher consumers, nekton (with an emphasis on cephalopods) fish, seals, whales, and seabirds. The following chapters explore selected ecosystem components; the benthic communities, life beneath the fast ice and ice shelves, recent advances in understanding decomposition processes, and the role of bacteria and protozoa. The author synthesizes ecosystem dynamics, with an emphasis on the pelagic ecosystem. He covers resource exploitation, the impact of such exploitation on the marine ecosystem, and the problems involved in the management of the living resources. His epilogue summarizes the extent to which our understanding of the functioning of the Antarctic marine ecosystem has changed in the last 50 years; for example, there has been a dramatic change in our view of krill and its role in the Southern Ocean marine ecosystem. The book concludes with the statement that research carried out under the AGCS Programme and the Scientific Committee on Antarctic Research (SCAR) will continue to provide critical information on the functioning of Antarctic marine ecosystems. Intended for all those with an ongoing interest in Antarctic research, conservation, and management, this volume represents one of the most authoritative resources in the field as it covers all aspects of this important marine ecosystem.

Antarctic krill (Euphausia superba) is the target of the largest commercial fishery in the Southern Ocean. Its abundance varies regionally and exhibits great interannual variability. This natural variability, combined with climate change effects, could have substantial consequent impacts on krill predators and the magnitude of ecologically sustainable fishery catch limits. Recent increase in the krill catch is due to technological developments in both harvesting and catch processing methods, as well as interest in new products derived from krill (e.g., dietary supplements and pet food). The krill fishery is managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). The krill fishery first commenced in 1970’s off East Antarctica, but the main fishing ground shifted to the South Atlantic sector from the 1990’s. Interest to fish off East Antarctica has been expressed by CCAMLR Member nations in recent years, and the krill fishery recommenced in Indian Ocean sector of East Antarctic sector in the 2016/17 fishing season. Given the increase in recent commercial interest – the ‘trigger level’ (total allowed catch) in one of the management areas (CCAMLR Subarea 48.1) has been reached seven times in the Southwest Atlantic – the East Antarctic fishery is likely to expand in coming years. CCAMLR employs an ecosystem-based management approach. This requires a wide range of data and information from across regional ecosystem components. In the southwest Atlantic sector krill management is based on large-scale krill biomass surveys undertaken in 2000 and 2019, together with various national Antarctic programs conducting annual regional-scale monitoring; this provides assessments of year-to-year variation of krill ecosystem parameters for CCAMLR to ensure harvesting is carried out in a sustainable manner. Contrary to the relatively data-rich Southwest Atlantic sector, current precautionary catch limits for the krill fishery off East Antarctica are solely based on information collected through the two large-scale multidisciplinary surveys conducted by Australia in Divisions 58.4.1 in 1996 and 58.4.2 in 2006. This Research Topic gathers up-to-date scientific analysis on the East Antarctic ecosystem arising from recent marine science voyages such as ENRICH (Euphausiids and Nutrient Recycling In Cetacean Hotspots) in 2019 and TEMPO (Trends in Euphausiids off Mawson, Predators and Oceanography) in 2021. Our topic provides an opportunity to explore ecosystem-wide scientific studies including (non-exclusively): krill biomass, ecosystem structure and interactions between krill, krill predators, oceanography and primary production, to inform sustainable krill fishery management in the region.

Marine/freshwater biological resources are of great economic, social and ecological value. Aquatic ecosystems, mainly formed by aquatic biological resources, play an important role in maintaining material circulation, energy flow, and environmental purification. Efficient, safe, sustainable utilization and high-value development of marine/freshwater biological resources, thereby promoting grain security, food security, and environmental security, has been a long term research focus. It is one of the most practical and innovative fields in global scientific and technological innovation and an effective way to solve the major problems restricting human resources shortage.
