The life spans of demersal species of fishes occurring in deep-waters are much longer and their potential growth rates much lower than those of related shallow water species. As a result, deep-sea demersal fish species are more vulnerable to exploitation. This is because low growth rates...

While the recurrent cost of managing marine protected areas (MPAs) has been documented and estimated, there has been virtually no attempt to quantify the cost of establishing MPAs in the first place. This lack of attention is likely the result of the complexity of the process, involving often...

A flurry of articles in recent years shows that loss of knowledge about the past may have contributed to an acceptance of other losses, such as declines in biodiversity. I first identified this form of collective amnesia in a 1995 article describing how fisheries biologists assess changes in...
