article_snippet.sent: Water temperature, tide level, fish motivation and the level of social interactions affected most acoustic parameters analysed (shown above).
article_snippet.sent: For example, during low tide, the sounds made by the fish were shorter in duration and had lower main frequencies .
article_snippet.sent: The sounds are modified by environmental factors such as tide level and water temperature as well as courtship motivation and by social interactions.
article_snippet.sent: For example, during low tide, the water temperature rises slightly and it's harder for sound to travel in shallow waters, which means that fewer fish sing and fewer fish noises are shorter in length and lower in pitch.
