  abstract = {{B}iomass evaluation by means of echo-integration, needs to be applied with strictness. {T}he better the dominant factors acting on the area are targeted and analyzed, the better will be the accuracy of estimation. {A} phase of descriptive observation is necessary, taking into account abiotic and biotic factors, as well as the one on species behaviour, as it can appear throughout the acoustics tool. {T}his descriptive stage will comfort the elaboration of a stratification which will serve as a model to calculate the abundance level and its accuracy. {D}uring acoustic cruises performed from 1992 to 1994 in the {J}ava {S}ea open waters, various parameters were measured. {R}egional differences can be observed, and they allow a three-area stratification to be elaborated.
