    Distribución del mercurio total en pescados y mariscos del Mar Argentino.
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1986) Pérez, A.; Moreno, V.J.; Aizpún de Moreno, Julia E.; Malaspina, A.M.
    Fish and shellfish samples for total mercury analysis were provided by the local fish export industry. Data collected through the years 1981-83 are processed and information was obtained on actual total mercury values in edible muscle of sampled species. On the basis of these results, future trends in mercury concentration values are hoped to be predicted. The authors suggest a revision of standards in force at present and the proposal of new ones, taking into account species involved and size of specimens.

    Estudios sobre el régimen alimentario del mero (Acanthistius brasilianus) y su relación con las características morfométricas del sistema digestivo (Pisces, Fam.Serranidae)
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1987) Goldstein, H.E.; Cousseau, M.B.
    Observations on the stomach content of the sea bass have been made in order to study the trophic spectrum and the feeding habits variations, according to the season, region and individual size. On the other hand, some morphometric and meristic characters of the buccopharyngeal cavity have been statistically analyzed in relation with the total length and compared with size and shape of the preys. The following characters were studied; length and width of the mouth; size of branchial arch; number and length of the gillrakers and distance between them.
