An overview of the argentine red shrimp (Pleoticus muelleri, Decapoda, Solenoceridae) fishery in Argentina : biology, fishing, management and ecological interactions.
The worldwide shrimp (Penaeid) landings has remained stable in almost 3.5 metric tons since 2012. The Argentine red shrimp (Pleoticus muelleri) fishery done in the Argentine Sea, has been the only crustacean fishery increasing their captures and its total value in recent years (FAO, 2016). Historically, landings of this species has been highly variable, with inter-annual differences of up to 30,000 metric tons, but since the 2006 fishing season annual landings have consistently increased up to a maximum of 170,000 tons in 2016 (Argentine Statistics, SSPyA, 2017). The Argentine red shrimp is the main target of part of the Argentinian freezer trawlers exclusively dedicated to catch this crustacean, in addition to coastal and deep-sea fresh trawlers that, depending on the commercially available marine resources, decide which species to catch. It life cycle is exclusively spent in marine waters, without any need to migrate to coastal lagoons and/or estuaries as other Penaeid families, thus being distinguished from most commercial subtropical and tropical shrimps. This shrimp fishery has been extensively studied by Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) since its beginnings, when large volume shoaling were detected in San Jorge Gulf at the beginning of the 1980s by the fishing fleet . INIDEP research is intended to present scientific data and management tools to avoid growth and/or recruitment overfishing of this important fishery for Argentina, with the objective to look for ecological sustainability. Studies regarding shrimp population dynamics, fishery assessment, status evaluation of benthic organisms found in the shrimp distribution areas, and continuous surveillance of the bycatch of bony and cartilaginous fish are carried out. Ecosystem approach goals are being developed with the purpose of understand and manage the ecosystem where the species thrive.Its northern and southern limit distribution are: Río de Janeiro, Brazil (23°00'S) and Santa Cruz, Argentina (50°0'S).
