ARANA, Patricio M.; ROLLERI, Renzo  and  DE CASO, Álvaro. Chilean Antarctic krill fishery (2011-2016). Lat. Am. J. Aquat. Res. [online]. 2020, vol.48, n.2, pp.179-196. ISSN 0718-560X.

Antarctic krill (Euphausia superba) is a key resource in the Antarctic region, as it is the primary food source for fish, whales, seals, flying birds, penguins and cephalopods. The high concentrations of the species and its possible uses -food for human and animal consumption and in the production of industrial, pharmaceutical and dietetic products- generates interest in the fishing industry. Its relevance motivated the implementation of administrative measures and international regulations for this fishery, which are summarized in this review. Chile is the only South American fishing country that has shown interest in participating in Antarctic krill fishery. Thus, between 1983 and 1994, the Fisheries Development Institute and some companies carried out fishing activities mainly aimed at prospecting and researching this species. However, starting in 2011, the factory trawler FV Betanzos began sustained commercial krill fishing aimed at krill meal production. This document analyzes the information collected by said vessel between 2011 and 2016, including areas of operation, fishing depth catches and CPUE obtained. Also, the main challenges faced by this fishery and the actions planned as solutions are assessed.

Keywords : Euphausia superba; krill; fishing operations; CPUE; Conservation Measures; Antarctic region.
