MOVIES+ Movies+ is a powerful tool for the acquisition, archiving and processing of fishing echo-sounder data. It has been used since 1998 during Ifremer oceanographic surveys for the evaluation of fisheries resources, etc.

MOVIES+ software is designed to perform echo-integration from any kind of vertical sounder with digital outputs. It can process standard echo-integration by quantifying back-scattered acoustic energy from specified depth and distance intervals along a transect. But it first enables the detection of shoals as acoustic detection structures, according to spatial, energetic and contiguity criteria. The shoal by shoal echo-integration may lead to a shoal species identification and a better biomass estimation.
