Se evaluó el desempeño productivo de bujurqui-tucunaré Chaetobranchus semifasciatus, paco Piaractus brachypomus y gamitana Colossoma macropomum criados bajo el sistema de policultivo y alimentados con una dieta extrusada de 25% de proteína bruta durante 160 días. Un total de 900 peces (peso inicial de 6.5, 25.8 y 25.3 gramos para bujurqui-tucunaré, paco y gamitana, respectivamente) fueron asociados en tres policultivos (T1: bujurqui-tucunaré + paco, T2: bujurqui-tucunaré + gamitana y T3: bujurqui-tucunaré + paco + gamitana), 2 2 distribuidos al azar dentro de nueve corrales de 100 m , a razón de 1 pez/m , densidad que se mantuvo hasta el final de estudio. La calidad del agua (transparencia, dióxido de carbono, alcalinidad, dureza, amonio, nitritos, temperatura, oxígeno disuelto y pH) fue monitoreada periódicamente. Los tres policultivos produjeron interesantes tasas de creci...

The tiger shovelnose catfish Pseudoplatystoma fasciatum (Linnaeus, 1766), a species widely distributed in South America, is a fish that due to its high-quality meat and fast growth, has been arising the interest of fish farmers, specially in countries like Brazil, Colombia, and Peru. The Peruvian governmental agency known as PROMPERU, has been looking for new international markets for this fish overseas, and at the same time linking efforts with other Peruvian organisms in order to develop strategies and studies that can lead to the establishment of a sustainable meat production of tiger shovelnose catfish, for international trade. One of these institutions is the Peruvian Amazon Research Institute–IIAP, which is developing a series of studies in order to generate culture technology for this catfish. The main goal of this study was to evaluate the effects of three feeding frequencies (...
