    Conocimiento biológico pesquero del recurso merluza (Merluccius hubbsi) y su pesquería en la República Argentina.
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero, 1995) Bezzi, S.I.; Dato, C.V.
    This paper summarizes the present knowledge on Merluccius hubbsi and its fishery in Argentina, based on the model proposed by the Technical Secretary of Comisión Técnica Mixta del Frente Marítimo, in 1990. It includes the taxonomic location of the species, its geographical distribution, stock unity, structure and population dynamics. It describes the fishing gear and fishing operations and presents the available information on selectivity and discards. The paper shows the data landings separated by fleet. Exploitation regulatory measures in force are included.

    Report of the INIDEP working group on assessment of hake (Merluccius hubbsi) north of 48° S (Southwest Atlantic Ocean)
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero, 1994) Bezzi, S.I.; Cañete, G.R.; Pérez, M.; Renzi, M.A.; Lassen, H.
    The assessment covers hake between 34° and 48°S (Argentina and Uruguay), excluding Golfo San Matías. Total international landings and Argentine catch-at-age and effort data available for the 1983-1991 period allowed an analytical assessment. Tunning of the VPA was made using Laurec-Shepherd analysis and Extended Survivor analysis. The results of these analysis are congruent with the information about the state of the stock. VPA biomass estimates are aound 2.1 and 2.7 mill. Tonnes, which are similar to those calculated through surveys. The Spawning Stock Biomass estimated for 1991 is considered to be within limits where the stock shows stable recruitment. At the present effort level, yield and Spawning Stock Biomass appear to remain stable. Management measures are also discussed.
