aIn this table a delivery represents a landing made at a specific dealer (processing facility) by a vessel and a particular fishing gear. For example, a boat that landed two market categories at a dealer, each of which was harvested using different gears, would result in two deliveries. There are cases when a vessel unloads some of its landings at one dealer and some at another dealer, where in this table, the multiple landings are together defined as a single delivery. Thus, the number of deliveries presented here does not correspond to the number of deliveries (fish tickets) given in Table 3.1. See section (3.2.2) for a further discussion regarding the system used in Oregon for processing fish tickets.
bCoverage estimates are calculated as:
[ (Number of deliveries with logbooks / Number of deliveries) x 100 ]
