    Algunos aspectos de la biología pesquera del langostino (Pleoticus muelleri) de la Bahía Blanca y un análisis del desembarco comercial del período 1955-1979
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1982) Bertuche, D.A.; Wyngaard, J.G.
    This study was carried out in order to get somme knowledge on the characteristics of the fisheries of the shrimp Pleoticus muelleri in the area of Bahía Blanca during 1980-1981. Monthly samplings in the fishing area were performed, and the landing data from 1955 to 1979 were analized.

    Estudio de edad y crecimiento de la sardina fueguina (Sprattus fuegensis) de las costas de la provincia de Santa Cruz e Islas Malvinas
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1982) Cousseau, M.B.; Gru, D.L.
    Samples of Sardina fueguina (Sprattus fuegensis) were taken during research cruises carried out in 1974 and 1978. Length and age frequency distributions were analyzed, and von Bertalanffy growth parameters were calculated for the coastal waters of two geographical regions: Province of Santa Cruz and northern part of Malvinas Islands. Lenght and weight growth curves have been calculated for each region and each year. Marked differences have been found between gowth parameters of both regions, and the calculated values showed a good fit with the observed ones. According to these results, it is possible to assume that the sardines of both regions constitute two different populations. However, more information on the total distribution of the species will have to be obtained in order to confirm the present observations.
