Target strength measurements on three pelagic fishes from the Java sea Cotel P. auteur aut IRD Petit Didier auteur aut IRD text conferencePaper eng text/pdf reformatted digital access Using acoustics for biomass evaluation, the back scattering cross section of species has to be determinated to convert the data into weighted values. During the cruises of EU Project "Java Sea Pelagic Fishery", TS measurements on three pelagic fishes of economic importance : Decapterus russelli, Selar crumenophthalmus, Rastrelliger kanagurta were carried out, using a Biosonics dual beam echosounder at 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.
