    Análisis de los desembarques declarados de condrictios a partir de la implementación de la veda en el área del Tratado del Río de la Plata y su Frente Marítimo (2006-2014)
    (Instituto Nacional de Investigación y Desarrollo Pesquero, 2016) Bernasconi, Juan F.; Monsalvo, Mariano; Prosdocimi, Laura; Martínez-Puljak, Gustavo; Navarro, Gabriela
    In 2007 the Comisión Técnica Mixta del Frente Marítimo established a closed area to bottom trawl in fishing rectangle 3656 to protect chondrichthyan reproductive aggregations and juveniles. The aim of this work was to analyze the evolution of said measure, the skate and shark landings declared during the 2006-2014 period in said rectangle and the distribution of the fleet before and after implementation. In the period evaluated, the duration of the closed area it was extended from 59 to 151 days and a reduction of tonnes of skates and sharks declared in the Argentine Uruguayan Common Fishing Zone of rectangle 3656 and an increase in the participation of said species in landings of the area of provincial jurisdiction was observed. The same trend was proved in the fishing activity if compare the season 2006-2007 (without closed area) and the season 2012-2013 (with closed area). During the closed season a northeast displacement of activities, a high catch level and fishing operations in the adjacent rectangles were observed.

    Biology and fishery of the Argentine hake (Merluccius hubbsi)
    (Instituto Nacional de Investigación y Desarrollo Pesquero, 2016) Irusta, Gabriela; Macchi, Gustavo J.; Louge, Elena; Rodrigues, Karina A.; D'Atri, Luciana L.; Villarino, María F.; Santos, Betina A.; Simonazzi, Mario
    Argentine hake (Merluccius hubbsi) is a demersal, eurythermic and euryhaline species associated to subantarctic waters of the continental shelf and slope. The species, considered the main fishery resource of Argentina that in 2011 reached the maximum catch and export levels, distributes from Southern Brazil to 55° S in a 50-400 m depth range. The three stocks identified, located between 34° S-41° S, south of said latitude and in the San Matías Gulf, show differences as regards reproduction and nursery areas and time, meristic and morphometric characters, abundance level and growth parameters. At the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) annual assessments of the exploitation status of the stocks north and south of 41° S are carried out and management recommendations made. In this chapter, the biology, fishery characteristics, population abundance and structure and management recommendations for the two main Argentine hake stocks are described.
