摘要：
Underwater acoustic and marine radar survey was conducted for assessment of fish near seabed and for seabed mapping. For the purpose, underwater acoustic instrument (split beam echo sounder), and ground penetrating radar (GPR) were used around Seribu Island, Jakarta Bay. Research vessel Mina Jaya (30 GT) and various marine research instruments were employed during the survey. The results show that fish density near seabed are 0.3 to 35.0 fish/1000 m(3) with fish length up to 44.6 cm. Radar has a high resolution for subbottom detection than high frequency acoustic.
