UNICIENCIA54502018-08-08T22:52:43Z The effect of high rearing densities on the growth of juveniles of the cichlid, cichlasoma managuense (Günther, 1869) (ESP) The effect of high rearing densities on the growth of juveniles of the cichlid, cichlasoma managuense (Günther, 1869) Günther Nonell, Jorge Gálvez Hidalgo, Nazira effect densities growth juveniles cichlid The effect of high density culture on the growth of juvenile jaguar cichlids was investigated. Mean growth rate decrease with density, while the growth rate of the largest fishes was not affected. Reduction in mean growth resulted from a greater number of stunted individuals as well as from a higher degree of stunting. Skewness appears to be a better indicator of competitive effects than the coefficient of variation. It is concluded that at least in stagnant waters, even high densities do not affect the strong dominance hierarchy which establishes among guapote juveniles. Se investigó el efecto del cultivo en alta densidad sobre la tasa de crecimiento de juveniles de guapote tigre. Mientras que la tasa de crecimiento promedio disminuye con la densidad, el crecimiento de los peces más grandes no resultó afectado. Con altas densidades de cultivo, el crecimiento promedio disminuye tanto debido a un mayor grado de enanismo en los individuos pequeños, como a que aumenta su cantidad relativa. El coeficiente de asimetría resulta ser un mejor indicador de los efectos competitivos que el coeficiente de variación. Se concluye que por lo menos en aguas estancadas, las altas densidades no afectan la jerarquía de dominancia que se forma entre individuos de guapote tigre.
