Reproducción, Crecimiento y Tasa de Explotación de Chiochio (Psectrogaster rutiloides) en la Cuenca del Río Ucayali entre 2008-2012

Abstract: El chiochio (Psectrogaster rutiloides) es una las 10 especies más representativas en la pesca de la flota comercial de Pucallpa, Perú. Esta investigación tuvo el objetivo de generar información para la comprensión de su biología y pesquería. Se estudiaron los aspectos reproductivos (época de reproducción, talla de primera madurez [TPM], proporción sexual), relación Longitud-Peso, crecimiento y tasa de explotación del chiochio desembarcado en puertos de Pucallpa entre 2008 y 2012. Datos de distribución de frecu… Show more

“…Mylossoma albiscopum from the Ucayali river basin, according to the seasonality of reproductive cycle, size and age at maturity and total spawning, can be considered as r‐strategic species, as defined by Winemiller (1992). The breeding period of M. albiscopum , which coincides with rising and high‐water periods, is a characteristic pattern of many migratory and commercially important Amazonian fishes (Bonilla‐Castillo et al, 2018; García‐Vásquez et al, 2015; Riofrío‐Quijandría et al, 2017). During this period, floodplains represents as biotopes that are used as refuge and breeding grounds for these species (Azevedo et al, 2021; Zacardi & Ponte, 2021), also generates favourable conditions for the development of plankton and periphyton that serve as food for the early life stages of these species, such as postlarvae and juveniles (Cajado et al, 2020; Campos‐Silva et al, 2021) that favour their development and recruitment (Castello et al, 2019), until they reach sizes that allow them to avoid predators.…”

“…La literatura existente muestra resultados solo para 56 especies, de un total de 1 141 especies reportadas para aguas continentales peruanas (MINAM, 2019). Los estudios han sido obtenidos a partir de datos colectados en estanques piscícolas (Felipa et al, 2016), a partir de desembarques en principales centros urbanos (Riofrío, 2002;García et al, 2010;Flores-Gómez, 2015;Riofrío-Quijandría et al, 2017;Bonilla-Castillo et al, 2018), y en algunos casos para determinadas cuencas (Alcántara et al, 2008;Tobes et al, 2015;Chuctaya et al, 2017;García-Ayala, 2017). Prochilodus nigricans (Familia Prochilodontidae) y Potamorhina altamazonica (Familia Curimatidae) son dos especies de gran importancia en la economía regional de Loreto.…”
