    Efectos del deterioro producido por mixosporidios de la especie Kudoa rosenbuschi en la musculatura de Merluccius hubbsi
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1987) Sardella, N.H.; Trinchero, J.L.; Manca, E.A.
    Parasitized and non-parasitized hake fillets obtained at fish processing plants were compared in order to assess the efects of Kudoa rosenbuschi myxosporidia on muscle of Merluccius hubbsi. The following studies were carried out: a) incidence and severity of parasitism; b) proteolytic and spoilage at a histologic level; c) pH and proximal composition in parasitized and non-parasitized fillets; and d) parasitism action on gelified products. Gel strength, elasticity and organoleptic level in gelified products were lower for parasitized samples. Recommendations are put forward as to conditioning and cooling of the catch and subsequent processing in order to lessen the effects of parasitism.

    Procesamiento y comercialización de la anchoíta (Engraulis anchoita) del Mar Argentino
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1986) Bertolotti, M.I.; Manca, E.A.
    The anchovy (E.anchoita) is one of the most abundant species in the Argentine Sea. Distributed in between latitudes 34°S and 48°S, it has only been caught, traditionally, along the coasts of Buenos Aires Province - particulary in the vicinity of Mar del Plata. Anchovy-like items are exported both to producing and consuming countries. During the last three years markets have been lost. In order to regain them and to develop new ones, particularly in Europe it shall be necessary to compete with products that are well-priced and of the high quality and have a substantial aggregate value. The anchovy domestic market could be enlarged- with certain limitations- be developing new products.
