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.
Antarctic krill (Euphausia superba) aggregations are important in the Southern Ocean ecosystem; however, the amount of energy that krill swarms contain is unknown. We assessed the population structure of E.
In February and March 2021 an acoustic-trawl survey was carried out to estimate the biomass of Antarctic krill (Euphausia superba) in the eastern sector of the CCAMLR Division 58.4.2 (area = 775,732 km2.)…
CCAMLR Conservation Measure 25-02 requires Spanish-system longline vessels to attach 8.5 kg weights at 40 m intervals on longlines to minimise interactions with seabirds. The weights typically used are collections of rocks enclosed in netting bags.
Based to a large degree on the precedent set by CCAMLR in 1991, the streamer line has … become the primary, and most commonly prescribed, seabird mitigation device in world … longline fi sheries. This paper reviews CCAMLR streamer line requirements (Conservation … Measure 25-02 (2002)…
