Resumen
Se tipifican las coloraciones juveniles y adultas del guapote tigre y se realiza un inventario de los despliegues agresivos de juveniles. En 5 cohortes peces en condiciones de cultivo intensivo se analiza la evolución del nivel de agresividad y la aparición de los diversos patrones agresivos hasta las 40 semanas de edad. Se establece la relación de algunos patrones de coloración con la posición jerárquica del animal. Se caracteriza el crecimiento de las cohortes observadas y se realiza su variabilidad con las consecuencias de la competencia en condiciones de alta densidad.
The aggressive behaviour and the color patterns of juvenile and adult jaguar guapote are described. In five different sibling groups in conditions of intensive culture the ontogeny of aggression is analyzed by the sequential appearance of the various aggressive displays and by the changes in aggressive motivation until the age of 40 weeks. A high correlation between some color patterns and the hierarchical position of the fishes is demonstrated. The growth parameters of the observed groups are quantified and the variability of the observed groups are quantified and the variability of growth related to be the consequences of enhanced competition in high density culture.
