| Se realizó un estudio piloto de cultivo intensivo por lotes en ciclos de cuatro días de rotíferos pequeños, Brachionus rotundiformis Tschugunoff, 1921, para la alimentación de peces marinos, basado en el uso de Culture Selco Plus® como alimento y oxígeno puro. Se aplicaron los mejores tratamientos de experimentos previos con oxígeno puro, flujo de agua abierto, uso de fibra sintética para la colecta de materia orgánica y el empleo de bombas dosificadoras para el suministro continuo del alimento. Con una densidad inicial de 252±21 rotíferos/ml se logró una densidad media de 1 595±53 rotíferos/ml a la cosecha, sin diferencias significativas entre las repeticiones (ANDEVA, P > 0,05). Los parámetros ambientales se mantuvieron estables e intervalos... |

| A new programme concerning the experimentation of about thirty Fish Aggregating Devices (FADs) is to start in the Cape Verde Islands at the end of 1999. In this context, this communication is intended: - to evaluate the halieutic, economic and social conditions of the artisanal fishery in this archipelago, notably in terms of assets and constraints. Although these conditions are very heterogeneous depending on islands, the fads seem to be able to help the stabilization and the development of the fishing activities, disadvantaged by a low productivity, limited operating ranges of boats, and very irregular outings at sea. But the narrowness of the domestic market is likely to cause drops in the fish prices if the production increases, while the absence of... |
