dc.description.abstract | Prognoses for catch of sprat in 1976 in different fjords of
western Norway are presented. The prognoses are based on
indices of abundance of 0-group sprat calculated from echo
recordings obtained on a survey in October-November 1975
by R. V. "Johan Hjort". The echo signals are processed by a
computer system, and a relative measure of sprat density per
distance travelled, combined with the area of each fjord, provides
the abundance index. This index reflects the abundance of sprat
available to the fishery 6 -8 months later. | en |
