Abalone survey in the Estevan Group and Aristazabal Island, June 1985 / by S. Farlinger and K.T. Bates. : Fs97-4/1896E-PDF

"Reductions in the commercial abalone fishery quota in recent years have been supported by surveys indicating substantial declines in the index of abalone abundance. In 1985, the Central Coast commercial fishing areas were resurveyed in response to reports of increasing availability of abalone. In 12 out of 25 comparative sites, an increase in density of legal size abalone was observed relative to the 1983 survey. Mean total density increased from 1.43 abalone per square meter in 1983 to 1.57 abalone per square meter in 1985. A non-significant increase in abalone density was observed in a comparison of new recruits and pre-recruits. The abalone population in the surveyed area does not appear to have decreased since 1983"--Abstract, page v.
