Résumé :	Red abalone (Haliotis rufescens) were assessed inside and outside a "de facto" reserve before fishing, after 3 and then 6 years of fishing. In just 3 years, there was a 65% decline (p 72% decline). Before fishing began, the intertidal density at the reserve was 86% greater (p = 0.001) than at a nearby fished site, however after 3 years of fishing there was no difference (p = 0.764). Abalone fishing report cards revealed a 950% increase in local catch once the reserve site was opened, however after just 1.5 years of fishing, catch declined sharply (59%) compared to the previous year. In 3 years, mean abalone catch per hour declined significantly (p
