Variable population responses by large decapod crustaceans to the establishment of a temperate marine no-take zone
In 2003, an area adjacent to Lundy Island was designated as the United Kingdom’s first no-take zone (NTZ) for nature conservation. The only significant fishery at Lundy was for lobster ( Homarus gammarus L.) and various crabs. The Lundy NTZ provided an opportunity to test hypotheses about the recove...

The NTZ also appeared to cause a small, but significant increase in the size of brown crab ( Cancer pagurus L.) and a decrease in the abundance of velvet crabs ( Necora puber L.) (the latter potentially owing to predation and (or) competition from lobsters). Unlike many previous studies, these results are unambiguous, owing to a robust asymmetrical experimental design. We suggest that regulatory and conservation agencies use this approach, which we have demonstrated to be relatively straightforward, whenever the NTZ requiring evaluation cannot be replicated.
