%X Using acoustics for biomass evaluation, the back scattering cross section of species has to be determined to convert the data into weighted values. During the cruises of the EU Project "Java Sea Pelagic Fishery", TS measurements on 3 pelagic fishes of economic importance : #Decapterus russelli$, #Selar crumenophthalmus$, and #Rastrelliger kanagurta$ were carried out, using a BioSonics dual beam echo-sounder at a frequency of 120 kHz. The observations on single or multiple targets in a cage, revealed a large dispersion of the responses, even in the same experiment. These results are discussed and compared with Johannesson's (Anonymous, 1984) in the same area. (Résumé d'auteur)
