A management plan for the sport fishery of Parachromis dovii (Pisces: Cichlidae) in Hule lake, Costa Rica
(Universidad de Costa Rica, 2000-06)A first attempt to regulate the fishing activity while preserving the species and its habitats is presented for Hule lake. We intensively sampled the "guapote" between March 1996 and April 1997 using monofilament gill nets ... -
Batch fertility and larval parameters of the jaguar cichlid (Cichlasoma managuense) spawned in the laboratory
(Universidad Nacional (Costa Rica), 1994-05-06)Abstract: Batch fertility and larval parameters of 32 spawns of the jaguar guapote (Cichlasoma managuense) in the laboratory were analyzed. Batch fertility was positively correlated with the female weight with spawns between ... -
Changes in digestive enzymes activities during the initial ontogeny of wolf cichlid, Parachromis dovii (Perciformes: Cichlidae)
(Sociedade Brasileira de Ictiologia, 2019)Wolf cichlid, Parachromis dovii, is a species with a high potential for aquaculture in Central America; however, the knowledge of the digestive physiology in larvae period is limited. For these reason, this study evaluated ... -
Crecimiento del guapote lagunero (Cichlasoma dovii) en regimen de cultivo intenso en estanques y su dependencia de la densidad
(Universidad Nacional (Costa Rica), 1996)Se determinan las características de crecimiento del guapote lagunero, Cichlasoma dovii, en régimen de cultivo intensivo en estanques de tierra y a dos densidades diferentes (1,4 y 2,8 peces /m2). El crecimiento y la ... -
Desarrollo del comportamiento agresivo en el Guapote Tigre (Cichlasoma Managunse, cichlidae) en relación con el crecimiento y la coloración de juveniles en cultivo intensivo.
(Universidad Nacional (Costa Rica), 1998-01-01)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 ... -
Effects of the protein: energy ratio in isocaloric diets on the growth of Cichlasoma managuense (Gunther 1869)
(Wiley & Sons, 1994)A feeding experiment was conducted to evaluate the growth of tiger guapote, Cichlasoma managuense (Gunther), fed on isocaloric diets with varying proteinxnergy ratios. The relative metabolic growth rate increased with ... -
Growth of Jaguar Cichlid (Cichlasoma managuense) juveniles at different oxygen levels
(Universidad Nacional, Costa Rica, 1992-01-01)The dependence of growth on the dissolved oxygen level was analyzed un juveniles of the guapote tigre, Cichlasoma managuense, in a recirculated system. The guapote tigre is relatively tolerant to low oxygen levels, averaging ... -
Intensive Rearing of Juveniles of cichlasoma managuense (Günther 1869) in recirculated systems
(Universidad Nacional, Costa Rica, 1991-01-01)The growth performance of guapote juveniles in recirculated systems from spawning to a mean weight of about 3 gramms is described. Culture began with a 15 days nursing phase with either first instar-nauplii or fresh ... -
Social effects in growth experiments. Growth of jaguar guapote (Cichlasoma managuense) in isolation and in small groups
(Universidad Nacional (Costa Rica), 1997)Se evaluaron el crecimiento y la conversión alimenticia de juveniles de guapote tigre (Cichlasoma managuense) mantenidos a densidades constantes de 1, 2, 5, 10 y 20 individuos por pecera. La densidad mostró una correlación ... -
The effect of high rearing densities on the growth of juveniles of the cichlid, cichlasoma managuense
(Universidad Nacional, Costa Rica, 1992-01-01)The effect of high density culture on the growth of juvenile jaguar cichlids was investigated. Mean growth rate decreased with density, while the growth rate of the largest fishes was not affected. Reduction in mean growth ... -
The growth of juvenile jaguar guapote (Cichlasoma managuense) fed diets with different carbohydrate levels
(Universidad Nacional (Costa Rica), 1995-06-27)Se evaluó el crecimiento de juveniles del guapote tigre (Cichlasoma managuense) alimentado con dietas isocalóricas conteniendo niveles de carbohidrato del 11 al 36 por ciento. El experimento se realizó en un sistema de ...
