1 INTRODUCTION Acoustic signalling using vocalisations is an important mode of communication in fishes (Amorim, 2006). These signals serve social functions such as individual recognition (Myrberg & Riggio, 1985), competitor evaluation during aggressive interactions (Ladich, 1997) and courtship displays (Amorim et al., 2003; Dos Santos et al., 2000; Mann & Lobel, 1997; Miguel Simões et al., 2008).
