    Contribución al estudio del comportamiento de las pinturas antiincrustantes: II) Influencia del contenido de tóxico
    (1969) Rascio, Vicente J. D.; Caprari, Juan José; Bastida, Ricardo
    Se ha continuado con el estudio del comportamiento de las pinturas antiincrustantes en las condiciones ambientales del puerto de Mar del Plata (Argentina). Se realizaron experiencias en balsa, en las cuales se determinó que en las pinturas a base de colofonia, la incorporación de cantidades crecientes de óxido férrico al pigmento, tiene influencia sobre el poder antifouling, el cuál se reduce a medida que aumenta la proporción de inerte. En pinturas vinílicas el estudio de esta variable ha dado resultados contradictorios. Se proporciona información sobre formulaciones oleoresinosas y vinílicas a base de diferentes tóxicos, que previenen totalmente la fijación de Jouling durante un año en el medio marino citado.

    Las incrustaciones biológicas en el puerto de Mar del Plata, periodo 1966/67: primera parte
    (1968) Bastida, Ricardo
    The present paper is the first part of a complete study about Mar del Plata port’s fouling communities. Besides biological aspects, ambiental factors and experiments on anticorrosive and antifouling paints were considered. An experimental raft was used for this purpose. Preliminary observations on the harbour benthic communities were made in order to establish its differences with those that are settled in the outer zones. The main difference observed is chiefly due to the low turbulence and organic pollution of the port’s water. Fouling organisms were collected on achrylic sanded panels immersed at different depths from the surface, being the maximun 2 meters. In this study two series of panels were used. The fouling process was recorded monthly during one year. The cumulative or long term panels were used in order to examine the fouling communities development from the beginning to the end of the experiment. These results will be informed in another paper.

    Preliminary notes of the marine fouling at the port of Mar del Plata (Argentina)
    (1967) Bastida, Ricardo
    Reference is made in this note to the qualitative and quantitative composition of the benthic communities of the Mar del Plata harbour (Argentina). Researchs on the fouling organisms were carried out based in our former studies of the area. This is the first time that fouling studies are being done in our country. Studies in detail of the fouling organisms constitute the present stage of the investigations, and are made over an experimental raft. As at the present time we have only reached up to the 6th month of observations, we are given a preliminary idea of the fouling development. We include the diagrams of the monthly main species frequency. Data of the accumulative panels are excluded.
