摘要：The movement of eels produces a sound called a hydrodynamic sound which is the sound or vibration that results from a change in the medium due to the movement of fish. Hydrodynamic sound intensity occurs when the direction and speed of fish swimming change rapidly. The deflection of the head position will cause a strong displacement of the medium. The displacement causes changes in pressure waves on the medium, which can be detected as sound by the hydrophone. This research aims to analyze the differences in the sound of elver phase eel fish and yellow phase in controlled conditions. The research was conducted at the Laboratory of histology and embryology of the Faculty of Biology, Gadjah Mada University. The research time is August 4-7, 2016. The tools used in this research are: Aquarium glass, headphones, hydrophone, Seaphone, alkaline battery box, laptop. The ingredients used were 5 yellow phase eel and elver phase respectively. Data processing is carried out with the help of the wavelab program 6 and analyzed using the Duncan Multiple Range test (DMRT). The results showed that the elver and yellow phase ell activities are very diverse in terms of the duration of eel's sound during morning, afternoon and night. Sound frequencies patterns recorded from 0 - 22.03 KHz. The sound frequency of ell is dominant from 151 - 450 Hz of range, and has different sound patern during morning, afternoon and night. The conclusion is that the duration and hydrodynamic sound patterns of elver phase eel and yellow phase were significantly different between morning - afternoon, also afternoon – evening, but for the morning - the evening is not significantly different.
