Resumen: "The Mexican cichlid, Cichlasoma beani has potential to be a candidate for the aquarium trade and the food industry.
However, currently there are no studies regarding the effect of environmental factors on the species in culture conditions.
The aim of this study was to assess the potential of C. beani to be maintained in cultured conditions. Additionally, the fish
were exposed to different temperatures to examine the effect of temperature on growth, condition and survival of cultured
juveniles in 26, 28 and 30°C, for six weeks in recirculation systems. Fish were fed 2.4 mm pellets (40% protein, 15% fat)
at a ration rate of 5% body weight per day (dry weight food: wet weight fish). An aggressive behavior in all treatments led
to lowered survival, making it impossible to conclude that temperature had an effect on the recorded variables. However
the results showed a tendency that indicated the final weight and specific growth rate at 30°C was greater than in 26 and
28°C, perhaps due to a better metabolism and nutrient assimilation."
