Two acoustical surveys took place in October 1993 and February 1994, covering the main part of the Java Sea, below a 50 m depth. The echo-integration process was performed through a BioSonics 120 kHz Dual Beam echo-sounder. Fish shoal characteristics and their behavioural aspects were observed. The shoals' configurations were extracted from the echograms and quantified. This information allows the spatial and bathymetric distribution to be presented. An analysis on the abundance and the distribution of shoals is proposed, as well as their contribution to the global clusters and a description of their behaviour during the day and night periods.
