this study aimed to evaluate the efficacy of silver sulfate (agso4) as a toxicant in goldfish (carassiusauratus). one hundred and forty-seven live specimens of c. auratus were obtained and exposed to 1, 10, 100, 500, 1000 and 2000 ppm of agso4for 96 hours. there was one control group (no agso4) and three replicates. the physicochemical properties of water and the following parameters were const...

The masking effects of tones on the detection auditory signals were studied in goldfish using the psychophysical tuning-curve paradigm. For signals below 350 Hz, masking is an inverse function of the frequency separation between masker and signal; a finding consistent with previous masking studies on fishes, birds and mammals. For signals above 350 Hz, masking peaks occur both in the 350 Hz reg...
