| Résumé: | Esta investigación tiene como propósito el de identificar las especies de los poliquetos bentónicos y conocer la actividad biológica de estos organismos marinos en las diferentes bahías y puertos en el área del Archipiélago de Galápagos, con la finalidad de determinar la composción, distribución y abundancia de cada uno de ellos y sus asociaciones existentes en la zona estudiada, durante el segundo Crucero de la Armada del Ecuador a bordo del B7I "ORION" entre septiembre y octubre de 1999.
During the II Oceanographic Cruise accomplished by the Oceanografic Institute of the Navy of the Ecuador aboard B/I "ORION" between September and October of 1999, 11 sediment samples obtained with drag type Van Veen, were studied in the principal ports and bays of the Genovesa (Bay Darwin)), Floreana (Pto. Velasco Ibarra). St. Cristobal (Naufragio) Bay), Isabel (Pto. General Villamil) and Santa Cruz Islands (Academy Bay) of the Galapagos Islands, Ecuador. In this period of taking samples the temperature of the water of the sea oscillated between 20° C in the south part under study are and 25° C northward. The salinity between 33.9 and 34.7 ‰. A total of 11 families of poliquetos (bentonic) distributed in 12 genus and 12 especies were identified, being Boccardia tricuspa the most frequent species with 41.6%, followed by Capitella capitata, Glicera branchiopoda, Ophiodromus sp. and Pilargis sp. with 16.6%, the other species represent 1%. The Naufragio Bay (St. Cristobal) was the area of highest abundance of specimens with 59 organism. The most extense diversity of 6 species was found on the Isabel Island in sediment of sand. |
