RUEDA, Mario Enrique  and  MANCERA P., José Ernesto. ALTERACIONES FÍSICO-QUÍMICAS DE LA COLUMNA DE AGUA, GENERADAS POR EL USO DEL BOLICHE (MÉTODO DE PESCA ARTESANAL) EN LA CIÉNAGA GRANDE DE SANTA MARTA, CARIBE COLOMBIANO. Bol. Invest. Mar. Cost. [online]. 1995, vol.24, n.1, pp.23-37. ISSN 0122-9761.

With the purpose of assessing the impact generated by the use of an artisanal fishing method populary called "boliche", in the tropical coastal lagoon Ciénaga Grande de Santa Marta, different aspects were quantified; being one of them designed to analyze some physical-chemical alterations of the water column, produced during the fishing operations. The dissolved oxygen concentration, water transparency and seston composition and concentration, before and after of 70 boliche's thrusts were determinated. The results show that fishing operations generate some momentary changes of little repercution to the ecosystem, such as particle resuspention principally inorganic an increase in seston concentration and a consequen water column transparency decrease. The dissolved oxygen concentration does not show appreciable alteration.
