Figure 3. Herring NASC per coverage part in Stratum 6 and 7 (in this case the strata are merged into one) from the spawning survey 15. February - 3. March 2025 (dates for each coverage part are given in Table 1). Each individual underlying NASC observation is mean NASC by transect (primary sampling unit), and the total mean of these is weighted by transect distances.
