Abstract:
This work aims to investigate the potential capabilities of an uncalibrated Multibeam Echosounder (MBES) in fish school detection, reporting an experience regarding an offshore gas platform in the Adriatic Sea If, on one hand, the Split beam Echosounder technology is traditionally used for the purpose of biomass evaluation , on the other hand recent improvements in Multibeam Echosounder MBES technologies and advancing in water column data processing have made possible to detect schools and obtain some relevant metric information, with the advantage that a wide surrounding environment could be quickly surveyed the possible results that can be obtained with this technology, strength points and weaknesses are presented in this paper. A reflection on other possible usages is given, and a replicable raw data processing method for schools detection and their metric characterization is presented as well.
