DETERMINACION DE EDAD EN “BOQUICHICO” (Prochiodus nigricans AGASSIZ, TELEOSTEI: Characoidei) MEDIANTE LECTURA DE ESCLERITES EN ESCAMAS.

Abstract: En la determinación de la edad en peces tropicales, se viene confirmando que uno de los mejores métodos lo constituye la lectura de marcas periódicas que se forman en las estructuras óseas. Últimamente se esta analizando un nuevo método que representa un avance del conteo de anillos diarios en otolitos a la lectura de esclerites en las escamas. En la presente investigación se aplica la metodología propuesta por WERDER (1983) y otras recientes contribuciones. Se analizan 191 ejemplares de “boquichico”(Prochilod… Show more

“…Loubens and Panfili (1992) reported age estimation, validation and related growth parameters for P. nigricans based on scale data for a Bolivian population. Others have estimated age based on sclerite numbers (Werder and Soares 1985; Montreuil and Tello 1988). Factors influencing growth of young P. nigricans and other floodplain fishes were reviewed by Bayley (1988).…”

“…The reproductive, growth and mortality patterns of P. nigricans have been studied in Bolivia (Loubens, Panfili, 1995), Ecuador (Silva, Stewart, 2006) and Brazil (Ruffino, Isaac, 1995;Catarino et al, 2014;Camargo et al, 2015). Surprisingly, in spite of its commercial importance, very few studies have been carried out on this species in Colombian and Peruvian rivers, apart from preliminary studies on its growth (Montreuil, Tello, 1988) and reproductive biology in Peru (Montreuil et al, 2001;Riofrío, 2002). Information about the population dynamics of this species is lacking to guide fisheries management.…”
