Rapid ichthyological inventory of lower Pachitea Basin, Peru
This paper reports on the fish diversity in the lower Pachitea River basin. In July 2005 a rapid inventory in 31 field stattions (14 rivers, 13 streams and 4 lagoons) was conducted. The area was located between Honoria (456195E, 8830474N) and Zungaro (486747E, 8965585N) between the departments of Huanuco and Ucayali. Fishes were caught using seines (4 mm, mesh), and 3967 were captured. 116 species, 25 families and eight orders were identified. Characiforms (59%), Siluriforms (22%) y Perciforms (12%) had the greatest richness. Commercial fishes as Cichla monoculus, Prochilodus nigricans, Salminus hilari, Hoplias malabaricus, Liposarcus sp., Plagioscion squomosissimus and ornamentals as Heros severus, Corydoras stenocephalus, Mesonauta festivus, Pyrrhulina brevis were fished too. Analysis of the richness by types of habitats showed that the streams were more diverses (64 species) than rivers (54) and lagoons (45). The rivers (1934 individuals) and streams (1745) were the habitat with higher abundances followed by and lagoons (253).

El presente trabajo informa sobre la diversidad de peces en la Cuenca del Bajo Pachitea. En julio de 2005 un inventario rápido en 31 estaciones (14 ríos, 13 quebradas y 4 lagunas) fue realizado. El área comprendió entre Honoria (456195E, 8830474N) y Zúngaro (486747E, 8965585N) entre los departamentos de Ucayali y Huánuco. Para la colecta se utilizaron redes de arrastre a la orilla, obteniéndose un total de 3967 individuos. Se identificaron 116 especies reunidos en 25 familias y 8 órdenes. La mayor riqueza la tuvieron Characiformes (59%), Siluriformes (22%) y Perciformes (12%). Se registraron especies de consumo humano como: Cichla monoculus, Prochilodus nigricans, Salminus hilari, Hoplias malabaricus, Liposarcus sp., Plagioscion squamosissimus; peces ornamentales: Heros severus, Corydoras stenocephalus, Mesonauta festivus, Pyrrhulina brevis. El análisis de riqueza por tipo de hábitat indica que las quebradas fueron las que presentaron mayor número de especies (64 especies), seguidas por ríos (54) y lagunas (45). Los hábitats con mayor abundancia fueron los ríos (1934 individuos), seguidos por quebradas (1745) y lagunas (253).
