| Del análisis de 12 tipos de diferentes maderas expuestas al medio marino, durante 3, 8 y 12 meses, entre Julio de 1984 y Junio de 1985; en cinco puertos de la costa Ecuatoriana, se encontró 8217 paletas, que pertenecen a 14 especies de moluscos bivalvos perforadores; de las cuales 13 pertenecen a la familia TEREDINIDAE y una a PHOLADIDA. Las especies más abundantes fueron: teredo fucífera con el 33%; Bankia gouldi con el 32% y Bankia orcutti con el 29,9%. entre las 14 especies encontradas en los cinco puertos estudiados. Bankia destructa fué la única especies que se presentó en todos los puertos o estaciones. En la costa Ecuatoriana, después de tres meses de exposición de las maderas al medio amrino, la especie más dominante fue Bankia orcutti, con el... |

| Continuous monitoring of Sea and Harbour (Lagoon) Surface temperature and salinity at two stations has been carried out from 1978 to 1981. This paper presents the findings for the period and relates it to the prevailing meteorological regimes. The pattern of sea surface temperature at Victoria beach in the study period shows a clearly defined mean maximum temperature of 29.34oC in April, and clearly defined mean minimum temperature of 25.63 in August. Depending on the year, there may be a less clearly defined mean maximum and minimum temperature in October/November and in January respectively. The pattern of surface temperature in the Harbour station is basically similar. The salinity cycle especially in the Harbour was found to be critically... |

| Les ports de mer, infrastructures terminales et lieux de rupture de charge entre les transports maritimes et continentaux, contrôlent toujours un arrière-pays qui peut déborder du cadre national et déboucher sur des pays enclavés, sans accès direct sur la mer. |

| En 1992 fueron visitados los puertos de Esmeraldas, San Mateo, Manta, Anconcito, Sta. Rosa, Engabao, Playas y Puerto Bolívar, obteníendose información de la actividad pesquera artesanal mediante un sistema de entrevistas aplicado a 2000 embarcaciones, las que en conjunto forman la flota operativa de los ocho puertos antes mencionados. El desembarque total acumulado durante 1992 se estimó en 38632,8 t, fluctuando entre 897 t en Playas y 9006 t en Anconcito. Este desembarque total acumulado fue superior al realizado durante los años 1990 y 1991. El esfuerzo pesquero se mantuvo casi constante en los puertos visitados durante 1992, sin embargo el número de botes activos registrados al día del muestreo presentó una variación significativa. |

| The survey of sediment and hydrological parameters in the old harbor of Bizerte has revealed that this ecosystem knows a high anthropogenic pressure. In this area waters were characterized by weak contents in dissolved oxygen and sediments, rich in fine fraction, were loaded in hydrocarbons and in organic matter. The free-living nematodes, predominant taxa, responded to these disturbances by a significant decrease in their densities and their biomasses and had tendency, notably at the most isolated sites, to penetrate deeply to escape surface sediments highly loaded in hydrocarbons and in organic matter. |
