  abstract = {{T}he present study objective was to determine some of the main life history characteristics of the chiochio, {P}sectrogaster rutiloides, a heavily fished, yet poorly studied species of the {P}eruvian {A}mazon. {O}ver an annual cycle between 2006 and 2007 a monthly sampling of {P}. rutiloides on the {I}quitos market provided a total of 2973 individuals. {T}he species reproduces during the rainy season, during the first part of the flooding period. {F}irst sexual maturity is reached at about 2years of age and 95mm standard length ({SL}) for both males and females. {B}atch fecundity was related to fish size and varied from 59800 to 149100 oocytes, with oocytes diameters of 1.34 +/- 0.11mm, valid for females of 141 and 152mm {SL} and of 102.9 and 149.6g body mass, respectively. {F}emales grew faster than males in every age class, a difference gradually increasing from 7% at age one to 10% at age nine, which corresponded to the oldest individuals sampled. {E}stimated mortality parameters and exploitation rates suggested over-exploitation of the species in the {L}oreto region.},
