The aims of this study is to report some characteristics of fishing trips, effort, catches, fishing areas and bycatch through observations on board and logbooks. 85% of sets were in the first 574 Km of distance from the coast (309 nautical miles). Farthest set was located at 1320 Km (712 nautical miles). A total of 382000 hooks were used to catch Mahi mahi, in 224 sets and 29 fishing trips, 94.6% of catch was Mahi mahi, 2.7% blue shark (Prionace glauca) y 1,3% mako shark (Isurus oxyrinchus). Also, 103790 hooks were used to catch sharks, in 109 sets y 12 trips, 81.9% of catch was blue sharks and 16.8% mako sharks. Catch per Unit of Effort (CPUE) for Mahi mahi shows significative difference among seasons; with a peak from November to January. CPUE for shark shows significative difference among seasons, with peaks in September and October. The Green turtle Chelonia mydas agassizii was the m...

The important breeding areas of Wedge-rumped storm petrel were unkwnown until recently. This species breeding in the central cost of Peru: Ferrol, Chao and Corcovado islands. We reported Santa island as a breeding area of this seabird. We located a total of 407 active nests, including 92 (22%) with eggs and 7 (8%) with chicks. Most breeding birds were found in an area near to the guard house in the east of the island,in the south and southwest of the island, where guano birds and large numbers of ticks were registered, we found few storm petrel nests. The south and southwest of the island has a high humidity and several of the dry-stone walls were covered with moss and algae. In those walls no storm petrel nests were found. It is possible other breeding sites exist on the Peruvian coast. Surveys of nesting areas in coastal Peru will provide much-needed information on Wedge-rumped storm-p...

Las áreas reproductivas de la Golondrina de la tempestad Peruana eran desconocidas hasta hace poco. Esta especie anida en la costa central del Perú, en las islas: Ferrol, Chao y Corcovado. Reportamos un área reproductiva para esta ave marina en la isla Santa. Localizamos un total de 407 nidos activos, incluyendo 92 (22%) con huevos y 7 (8%) con polluelos. La mayor parte de las aves reproductivas se hallaron cerca de la casa al este de la isla, en el sur y suroeste, donde se registraron aves guaneras y altas cantidades de garrapatas pocas golondrinas fueron halladas. En el sur y suroeste de la isla la humedad contribuye a que algunas pircas estén cubiertas de musgos y algas, en estas paredes no se hallaron aves anidando. Es posible que existan otras áreas de reproducción en la costa peruana. Estudios de las áreas de anidación en la costa del Perú proveerá la información necesar...
