Chilean jagged lobster, Projasus bahamondei, in the southeastern Pacific Ocean: current state of knowledge

Abstract

ABSTRACT. The Chilean jagged lobster (Projasus bahamondei) is a deep-water crustacean (175-550 m) occurring in certain areas of the southeastern Pacific Ocean, including the Nazca Ridge, Desventuradas Islands, the Juan Fernandez archipelago and ridge, and the continental slope off the central coast of Chile. This review describes the taxonomic status, geographical and bathymetric distribution, some biological aspects and habitat characteristics of this species. Additionally, both artisanal and industrial exploitation attempts made within the region are detailed, as well as fishing operation results, chemical composition, different elaboration procedures and the destination of the catch. The main objectives of this review are to contribute to the knowledge of P. bahamondei as a component of the deep-sea ecosystem and to highlight its importance as a potential fishery resource. Keywords: Projasus bahamondei, Chilean jagged lobster, distribution, biology, fishing, southeastern Pacific.Langosta enana, Projasus bahamondei, en el océano Pacífico suroriental: estado actual de conocimiento RESUMEN. La langosta enana (Projasus bahamondei) es un crustáceo de aguas profundas (175-550 m) presente en el océano Pacífico suroriental: en la cordillera de Nazca, islas Desventuradas, archipiélago y cordón submarino de Juan Fernández y en el talud continental frente a la costa central de Chile. Se describe su estatus taxonómico, distribución geográfica y batimétrica, diferentes aspectos sobre su biología y las características del hábitat donde vive. Adicionalmente, se detallan los intentos de explotación realizados en la región, tanto a nivel artesanal como industrial, así como los resultados de las operaciones de pesca, su composición química, los diferentes procesos de elaboración y el destino de las capturas. El principal objetivo de esta revisión es contribuir al conocimiento de P. bahamondei, como componente del ecosistema de aguas profundas, así como destacar su relevancia como recurso pesquero potencial en el océano Pacífico suroriental.

Record of stomatopods and decapods, including descriptions of the species of commercial interest from the submarine rises and surrounding waters of the Chilean oceanic islands (southeastern Pacific Ocean)

“…On the Nazca Ridge, this species has been recorded between 225 and 420 m (Arana & Venturini, 1991;Arana & Soto, 1994;Parin et al, 1997;Arana, 2014a), and around Robinson Crusoe and Santa Clara at depths of 250 m (Arana & Vega, 2000). In the South American continental slope, the bathymetric range inhabited by this species is between 175 and 550 m (Dupré, 1975;Andrade & Báez, 1980;Báez & Weinborn, 1983).…”

First Description of Phyllosoma Larva in the Genus <i>Projasus</i> (Crustacea: Decapoda: Palinuridae)

“…They are deep-water dwellers found in south American, south African, and southern Pacific regions (Holthuis 1991). In the previous life history studies on Projasus, only the postlarval puerulus stage has been described from the Chilean and Australian waters (Berry 1974;Webber and Booth 1988;Báez and Ruiz 2000;Arana 2014). No information about the larval phyllosoma stage of Projasus has been presented to date.…”
