- Maturity size and fecundity of hybrid tilapia Oreochromis aureus X Oreochromis niloticus (Perciformes: Cichlidae) from the reservoir Fernando Hiriart Balderrama “Zimapan”, Hidalgo, Mexico Mario Alejandro Gómez-Ponce Claudio Manuel Padilla–González Martín López-Hernández Gabriel Núñez- Nogueira Laura Fernández-Bringas Multidisciplinaria (Ciencias Naturales y Exactas) hybrid fecundity Sexual ratio gonadic maturity condition factor Maturity size and fecundity of hybrid tilapia Oreochromis aureus X Oreochromis niloticus. (Pisces: Cichlidae) from the reservoir Fernando Hiriart Balderrama “Zimapan”, Hidalgo, Mexico were deter- mined in organisms caught between 2007 and 2008. A total of 506 hybrid fishes were captured and showed a range of sizes from 20 to 28,9 cm standard length ( S L ), and total weight of 200 to 750g ( T w ). The estimated maturation size for females was 20,8cm and 22cm for males, respectively. Fecundity was estimated on 50 gonads and a mean of 3 113±1 826 eggs was recorded per gravid female. Based on these re- sults, these fishes are suitable for commercial exploitation and imply good conservation in correlation to the regulatory strategies for fisher- ies established in the area, at least from a reproductive point of view. 2015 artículo científico 1659-4266 https://www.redalyc.org/articulo.oa?id=515651796003 en http://www.redalyc.org/revista.oa?id=5156 UNED Research Journal / Cuadernos de Investigación UNED application/pdf Universidad Estatal a Distancia UNED Research Journal / Cuadernos de Investigación UNED (Costa Rica) Num.2 Vol.6
