On subjectivity in the judging of acoustic records; comparison of degree of homogenity in allocation of echo values by different teams

On four fish abundance estimation surveys in the Barents Sea, january-february 1993, the acoustic records were judged by two independent teams. We have analyzed the degree of homogenity in allocation of echo values to various species by the different teams. In general the average echo value allocate...
