dc.description.abstract | The entrance region to Tysfjorden was acoustically surveyed a total of eleven times
during the December 1996 abundance survey of the spawning stock of Norwegian
spring-spawning herring (Clupea harengus). The observations are summarized
through maps of the distribution, vertical sections, and statistical measures of acoustic
density in each of two strata. Experimental variograms are modeled, yielding
parameter values that summarize the major properties of aggregation. The collective
measures of density and aggregation portray a highly dynamic situation with strong
diel variation but a general persistence of the fish distribution over the eleven days of
its repeated observation. | no_NO |
