Distribución y abundancia de la raya del Magdalena (Potamotrygon magdalenae: Potamotrygonidae) en el Complejo Cenagoso de Zapatosa, Colombia

Abstract: La raya del Magdalena (Potamotrygon magdalenae) no es considerada una especie objetivo de las pesquerías de la cuenca del Magdalena. Habitualmente es descartada viva, no sin antes quebrarle la espina caudal o aguijón, por lo cual no aparece frecuentemente en los desembarcos artesanales de esta zona, de allí que se desconozca el impacto sobre sus poblaciones. Este estudio determinó la distribución espacial de la abundancia y los tamaños de P. magdalenae en el Complejo Cenagoso de Zapatosa (CCZ). A partir de una… Show more

“…The reproductive strategy of P. magdalenae consists of early sexual maturity, high fecundity, small offspring, and likely a continuous reproductive cycle (Mejía‐Falla et al, 2016). Furthermore, various studies on the biology, physiology, and ecology of P. magdalenae have been conducted (Anaya‐López & Ramírez‐Pinilla, 2017; Castañeda et al, 2021; Lizcano‐Gutiérrez, 2022; Márquez‐Velásquez et al, 2019; Mejía‐Falla et al, 2016; Ogawa & Hirano, 1982; Pedreros‐Sierra et al, 2016; Pedreros‐Sierra & Ramírez‐Pinilla, 2015; Pérez‐Rojas et al, 2020; Ramos‐Socha & Grijalba‐Bendeck, 2011; Singer & Ballantyne, 1989; Teshima & Hara, 1983; Teshima & Takeshita, 1992). However, to date, there has not been any research of this species' thermal biology.…”
