| dc.description.abstract | A low cost system for integration of echo signals on a PC has been developed. The system
calculates the area backscattering strength in surface and bottom layers, and is designed both
for the purpose of conventional acoustic abundance estimation and for quantification of fish
school structure. The system has been installed onboard R/V "Fjordfangst" (20 GRT), and
echo integration trials of herring schools have been conducted in Northern Norway. These
measurements revealed great variations in internal packing density of the schools. | no_NO |
