Spratt, Jerome D.
In Tomales Bay, 4-, 5-, and 6-yr-old herring, Clupea harengus pallasi, composed 70% by number of the 1985-86 season's catch. In San Francisco Bay, 2-, 3-, and 4-yr-old herring composed 78% by number of the roundhaul catch, and 4- and 5-yr-old herring composed 64% by number of the gill net catch.The percent of 4-yr-old herring in both the Tomales Bay catch (25% and San Francisco Bay gill net catch (39%) is at a high level for the second year in a row.Recruitment of 2-yr-old herring into the San Francisco Bayroundhaul fishery was about average, with 2-yr-old herringcomposing 33% of the catch.The mean length of herring in the San Francisco Bay roundhaul catch increased to 178 mm BL, while the mean length of the gill net catch remained 196 mm BL. The mean length of the Tomales Bay catch decreased to 198 mm BL due to the increased number of 3- and 4-yr-old herring in the catch. (18pp.)
