Investigation of echosounder finger prints of Dutch pelagic freezer trawlers (SEAT II) evaluation of the SEAT II joint-industry project : evaluation of the SEAT II joint-industry project

The SEAT algorithm aims at classifying different fish species using relative frequency response acquired by downward looking echosounders operating at multiple frequencies. The performance of the system has been being evaluated on three Dutch freezer trawlers: Fishing Vessel (FV) SCH302 Willem van der Zwan, FV SCH6 Alida and FV SCH24 Afrika. One of these vessels (FV Alida SCH6) operates a mixture of SIMRAD EK60 & EK80 software while others operate only Simrad EK80. As reported by these vessels, the classification accuracy of the SEAT software has been reduced particularly at the later stag... Mehr ...
