Summary

AKES (“Antarctic Krill and Ecosystem Studies”, 2008-2011) was an IMR project that focused on mapping the abundance and distribution of Antarctic krill (Euphausia superba) in the central to eastern parts of the Atlantic sector of the Southern Ocean. Through the project IMR has contributed with highly relevant science and new knowledge to the management of ecosystem resources within the management area of CCAMLR (“Commission for the Conservation of Marine Living Resources”). The expedition was conducted during two consecutive surveys carried out during the Austral summer of 2008. In these areas, detailed knowledge of the ecosystem is limited and poorly described. This report presents results from taxonomic analyses performed on fish worked up from trawl catches in the upper ~750 m of the water column. Taxonomic identifications are based on morphological characteristics using the most updated identification keys. Following identification, each species or genus is illustrated by an image, while its distribution and numbers caught are presented in associated figures and tables. This work is important for future surveys in the Southern Atlantic when assessing ecosystem change, bycatch related to ongoing and new fisheries, management as well as the functionality and design of future marine protected areas (MPA’s). For further descriptions of relevant survey design, methodology, trawl gear and associated investigations, see descriptions in Iversen et al. (2008) and Krafft et al. (2010).

1 - Background

AKES 2008-2011 (Antarctic Krill and Ecosystem Studies) was an IMR (Institute of Marine Research) project primarily aimed to investigate the abundance and distribution of Antarctic krill (Euphausia superba) in a region of the Atlantic sector of the Southern Ocean (Figure 1), where knowledge about the ecosystem is limited. The expedition consisting of two survey legs carried out during the Austral summer of 2008 (4 January to 28 March) in the CCAMLR (Convention on the Conservation of Antarctic Marine Living Resources) area.

Map — Figure 1. The AKES survey was conducted as two separate expeditions or legs. Leg_1 started from Montevideo, Uruguay 4th of January 2008 and ended in Cape Town, South Africa 14th of February. Leg_2 started when the vessel departed Cape Town 19th of February 2008 to survey the Southern Ocean along two transects, to and from the Astrid Ridge, and ended 28th of March 2008 in Walvis Bay, Namibia.

Trawling was carried out throughout the area to a maximum of ~750 m depth to the surface. For description of the survey design, methodology and trawl gear, see Krafft et al. (2010).

This report focuses on describing the results based on the fish that were sorted from the total catch where individuals were determined to the highest taxonomic level possible. Total weight per species and individual lengths were measured, following standard methodology described in Mjanger et al. (2007). Taxonomic identification was based on Gon & Heemstra (1990). In cases where taxonomic identification from the work carried out on board needed further validation; they were photographed and frozen for further onshore analyses. Each identified species or taxon is presented with an image, distribution map, station information (including number of specimens, weight (W), total catch weight of fish (TW fish) and total weight of catch (TW catch)), and for the most abundant species a length histogram. Lengths of fish are normally measured as total length (TL) from tip of snout to the end of the caudal fin ("untouched") or as standard length (SL) from tip of snout to the posterior end of the last vertebra. Validity of scientific names was checked with Fricke et al. (2020), systematic order is according to van der Laan et al. (2020), and English common names according to Froese & Pauly (2019).
