Abstract: Standardized catch rate of cockfish, Callorhinchus callorynchus, in a bottom trawl fishery of Patagonia: Is it possible its use as a predictor of abundance trend?The catch per unit of effort (CPUE) data of cockfish, Callorhinchus callorynchus, during 1986-2011 was evaluated for the bottom trawl fishery of the San Matías gulf (Patagonia, Argentina). The objective of this work was to detect what are the factors related to fishery dynamic that affect catch rate of cockfish and to assess standardized CPUE by Gener… Show more

“…Along the Argentinean Sea (south-western Atlantic Shelf between 35º S and 55º S), this species is abundant from coastal waters to 200 m depth and an important resource for recreational and small artisanal fisheries (Consejo Federal Pesquero, 2009;Cedrola et al, 2011;Cousseau, Perrotta, 2013). Argentinean landings of C. callorynchus represent 97% of the total south-western Atlantic catches of this species (Bernasconi et al, 2015a). In addition, there has been an increase in Argentinean landings from 1992 to 2011, with the highest one recorded in 2009 (2782 tons) (Sánchez et al, 2012;Navarro et al, 2014;Bernasconi et al, 2015a).…”

“…Callorhynchus callorhynchus was one of a few ghost sharks assessed as threatened. Its widespread, inshore distribution off the coast of South America in the Southwest Atlantic and Southeast Pacific Oceans subjects the species to intensive fishing pressure throughout the year across most of its depth and spatial distribution (Aedo et al., 2010; Alarcón et al., 2011; Bernasconi et al., 2015). It is utilized for its flesh and fins in local and international trade (SUBPESCA, 2020).…”

“…De maneira geral, podem ser utilizadas três abordagens: A) ano incluído no modelo apenas como efeito fixo principal (e.g. Bernasconi et al, 2015); B) ano incluído no modelo como efeito fixo principal, mas também em interações de efeito fixo (Mourato et al, 2016) e, C) o ano incluído como efeito fixo principal e também nas interações de efeito aleatório (Wang et al, 2014). O principal objetivo da incorporação do fator ano no modelo é detectar tendências ao longo do tempo na abundância.…”
