Research on the behavior of eels with bioacoustics has never been done, because eels are catadromus fish that lay eggs in the deep sea and then grow in freshwater area. This study aims to observe the behaviour of Anguilla bicolor when feeding with passive sonar bioacoustic methods by hydrophone in the elver and yellow phases. The eel is placed in an aquarium and fed with pellets. The data were processed to get the duration and characteristics (frequency and intensity) of sound. Data were analyzed using the Duncan Multiple Range Test (DMRT) to determine the difference in the sound of eel before and during feeding. The results showed that the duration of the sound of the elver phase fish was significantly different for the duration before and after feeding, but for the yellow phase, the duration before and after feeding was not significantly different. When compared between the elver and yellow phases for before and when feeding both are significantly different. The sound pattern of elver phase itself is significantly different for before and after feeding, as well as for the yellow phase. When compared between the elver phase and the yellow phase on the sound pattern before feeding it was not significantly different, so did the sound pattern of the elver phase when feeding was not significantly different than the yellow phase sound when feeding. The conclusion of this study shows that the bioacoustic of eel fish comes from the movement of fish when swimming. Each phase of eel has different sound characteristics seen before feeding or when feeding. © BIOFLUX SRL. All rights reserved. |
