Abstract
The 1989 red abalone sport creel was conducted at eleven key study areas in Humboldt, Mendocino, Sonoma, and San Mateo counties where 1,247 divers and 1,408 shorepickers were interviewed. Boat divers were the most successful type of access, followed by shore divers and shorepickers. Shelter Cove, as in 1988, ranked last among study areas in catch rates, return rates, and size of abalone taken. Creel survey and random telephone survey data were combined to estimate effort, take, and return mortality for the red abalone sport fishery in northern and central Californiafrom Monterey through Del Norte counties for 1989. The 1989 telephone survey results showed most red abalone sport fishing trips were in Mendocino county (47.7%) and Sonoma county (40.5%). The results of the 1989 combined creel and telephone survey indicated 56,178 (35,216 to 77,139) divers, and 24,277 (12,352 to 36,102) shorepickers participated in the fishery. However these estimates were inflated by not considering sportsmen that repeated trips throughout the season. An estimated 88,320 (60,729 to 115,911) diving trips and 46,676 (26,668 to 66,685) shorepicker trips were made. The estimate of landed weight in the shell by both divers and shorepickers combined was 1,160,729 (865,862 to 1,455,595) pounds. Red abalone return mortality in 1989 was 3.3% of total mortality for divers and 6.6% for shorepickers. (97pp.)
