Results of the 1985 winter acoustic survey of NAFO Div. 4WX herring stock / by Udo Buerkle. : Fs70-8/86-47E-PDF
"An acoustic herring survey was carried out on the winter fishing grounds of the SW Nova Scotia herring stock. As in previous years, herring were found concentrated in a small area. Replicate surveys of the area of concentration during five nights showed biomass to vary by a factor of about three. Differences in length distributions of herring caught on different nights raise the possibility of a different population of herring moving into the area between Jan. 24 and 30. The maximum biomass recorded was 74% of that recorded in 1984"--Abstract.
