Can fisheries-induced evolution shift reference points for fisheries management?
A new paper in the ICES Journal of Marine Science discusses whether and how fisheries-induced evolution will shift reference points, a key tool in fisheries management.
ICES Journal of Marine Science has just published a paper entitled Can fisheries-induced evolution shift reference points for fisheries management? Fisheries-induced evolution alters fish life histories, and consequently, population characteristics (see the figure below). Because of these changes, it will also lead to “shifting” of reference points by modifying the underlying biological processes or by changing the perception of a fishery system. Whether these changes make the reference points more or less precautionary than intended depends on the details—the reference point in question as well as the biological and fishery context. The bottom line is that the reference points will change. And unless updated, their intended meaning will gradually be lost.
In addition to discussing reference points, the paper also reviews our current knowledge on life-history responses to exploitation and the population and fishery level consequences of these. It is a good read for any body interested in fisheries-induced evolution!
The paper is coauthored by the participants of the Study Group on Fisheries-Induced Adaptive Change (SGFIAC), now Working Group on Fisheries-induced Evolution (WGEVO). The group includes many past and present EvoFishers.
