| الوصف: | Abstract Marine reserves aim to protect harvested species within their boundaries and can therefore provide insurance against the effects of overfishing. To evaluate whether marine reserves are meeting this expectation, we compiled over 40 years of rock lobster (Jasus edwardsii) monitoring data and examined long‐term trends in three relatively small marine reserves (c.4–8 km2) in northern New Zealand, a region that has experienced large‐scale declines in the fishery over the last decade. In all three reserves, lobster density initially increased by at least a factor of three following protection. However, over the last 10 years, lobster populations have experienced large declines in all three reserves with densities now 59–80%, and spawning stock biomass (SSB) now 51–86%, below historic levels. Using peak lobster density in each reserve as an unfished reference point, current densities on fished reefs are |
