J. Astrup et B. Mohl, DISCRIMINATION BETWEEN HIGH AND LOW REPETITION RATES OF ULTRASONIC PULSES BY THE COD, Journal of Fish Biology, 52(1), 1998, pp. 205-208
Cod were trained to detect a shift in the repetition rate of intense u
ltrasonic pulses (approximately 210 dB re 1 mu Pa). For cod exposed to
predation by toothed whales, this ability may provide information to
guide evasive manoeuvres. (C) 1998 The Fisheries Society of the Britis
