Despite its importance, biological information about this species is too scant to guide fisheries management in this portion of the Colombian Amazon. In this study, 10884 individuals were sampled in the fish markets of Puerto Leguizamo between 2009 and 2017. This sampling was used to document reproductive patterns, but also growth and mortality parameters from length frequency distributions. The size at which all fish were mature was 22 cm Ls, which should be the established as the minimum size of capture to ensure that all fish have had a chance to reproduce before being caught. Growth and mortality parameters indicated a slower growth in the Putumayo than in other Amazonian rivers and a relatively high exploitation rate. specialized Black prochilodus Colombia Growth Mortality Reproduction AMAZONIE PEROU EQUATERU COLOMBIE PUTUMAYO COURS D'EAU 034 16 2 art. 170139 [12 p.] 2018 1679-6225 https://www.documentation.ird.fr/hor/fdi:010073645 10.1590/1982-0224-20170139 1679-6225 [F B010073645] https://www.documentation.ird.fr/hor/fdi:010073645 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-09/010073645.pdf IRD - Base Horizon / Pleins textes 2018-09-12 2018-10-03 fdi:010073645 fre
