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 OceanDocs
Rueda, Mario E.; Mancera-Pineda, José E..
Con el propósito de evaluar los impactos generados por el uso de un método de pesca artesanal denominado "boliche" en la laguna costera tropical Ciénaga Grande de Santa Marta, se cuantificaron diferentes aspectos; uno de los cuales fue orientado a analizar algunas alteraciones físico-químicas de la columna de agua, producidas durante la maniobra de pesca. Se determinó la concentración de oxígeno disuelto, la transparencia del agua y la concentración y composición del seston, antes y después de 70 lances de boliche. Los resultados indican que la maniobra de pesca genera algunos cambios momentáneos de poca repercusión en el ecosistema, tales como resuspensión de partículas principalmente inorgánicas, aumento de la concentración de seston y en consecuencia...

Historia de vida y dinámica de poblaciones de Lychnorhiza lucerna (Scyphozoa) ¿Un recurso pesquero alternativo? OceanDocs
Schiariti, A..
In this Thesis we presented the first steps in the study of the life history and population dynamics of Lychnorhiza lucerna as well as the possibilities of development of its fishery in Argentina. L. lucerna presented a metagenetic life cycle characteristic of most scyphozoans. Polyps reproduced asexually by the production of podocysts and polidisk strobilation. The combination of both types of asexual reproduction resulted in a high strobilation rates indicating that the abundance of medusae would strongly depend on polyps abundance and reproduction. The absence of ephyrae in the Río de la Plata estuary suggest that L. lucerna doest not complete its life cycle locally but medusae would be produced by polyps located northwards along the Uruguayan or...

Impact du milieu sur les nourricieres de poissons plats de la Baie de Seine ArchiMer
Duval, P.
This study has two objectives: (1) the knowledge of spatial and temporal characteristics of flat fish nursery grounds, and, (2) the determination of natural or man-induced factors affecting these nurseries: hydrodynamics, sediment properties, predation, competition, water quality, pollution. To protect these grounds the author proposes a fisheries management plan and an impact study before all port installations or all coastal equipment use.
Tipo: Text Palavras-chave: Resource conservation; Predation; Juveniles; Flatfish fisheries; Pollution effects; Environmental impact; Estuarine fisheries; Nursery grounds.
