It is important to understand that there are sometimes perceived 'negative' effects of protecting a species from exploitation. However, the overwhelming take-home message from this paper seems to me that lobster populations within the No-Take Zone at Lundy are thriving and likely to benefit the fishery through export of larvae and perhaps adults displaced by overcrowding. The higher incidence of (low level) disease in large males is, well, perhaps what happens when you get older. I am surprised that a title that majored on, what I think is, a minor and unsurprising (for older animals) 'cost' passed the referees.
