A series of acoustic surveys of the adult component of the Norwegian
spring-spawning herring was conducted in Ofotfjorden and Tysfjorden in December
1992. Preliminary results are reported. These include compensation for the
effect of extinction when estimating mean abundance, and allowance for
autocorrelation when estimating associated variance by means of geostatistics.
