Spatial Management of Fisheries

MPA Network Design and the Value of Spatial Fisheries Management

In the last two decades, networks of marine protected areas (MPAs) have been created at a rapid rate around the world. Because MPA locations are often difficult to change once established, the design process is a crucial step for achieving successful networks. Here I use a bioeconomic model of seven nearshore fisheries in Southern California to estimate the value of MPAs relative to other manag...

Modeling spatial patterns in fisheries bycatch: improving bycatch maps to aid fisheries management.

Fisheries bycatch, or incidental take, of large vertebrates such as sea turtles, seabirds, and marine mammals, is a pressing conservation and fisheries management issue. Identifying spatial patterns of bycatch is an important element in managing and mitigating bycatch occurrences. Because bycatch of these taxa involves rare events and fishing effort is highly variable in space and time, maps of...

Toward Darwinian fisheries management

There is increasing evidence that fishing may cause rapid contemporary evolution in freshwater and marine fish populations. This has led to growing concern about the possible consequences such evolutionary change might have for aquatic ecosystems and the utility of those ecosystems to society. This special issue contains contributions from a symposium on fisheries-induced evolution held at the ...
