We sought to establish baseline values for two basic reflex behaviors and for ventilation rate in the toadfish, Upsanus tau, over a range of temperatures. Righting response and escape response were chosen as measureable reflexes indicative of activity level in these animals. Between September, 1996, and January, 1997, ten fish were held in an isolated tank at ambient temperature in the Marine R...

The present exposition was designed to evaluate blood serum changes in tiger grouper, Epinephelus fuscoguttatus in response to changes in water temperature and salinity. Uniformly sized fingerlings were randomly distributed into different groups at fifteen fish per tank, in two replicates. Each group represented experimental fishes subjected to water temperatures of 18, 24, 28 and 30°C (control...

The effect of intermittent feeding on growth, feed utilization and body composition of subadult olive flounder fed extruded pellet (EP) in suboptimal temperature (13.5±2.10°C) was determined. Two hundred twenty five subadult fish averaging 272 g were randomly distributed into fifteen of 300 L circular flow-through tanks (fifteen fish per tank). Five treatments with different days of feeding a w...
