Can fisheries-induced evolution shift reference points for fisheries management? ArchiMer
Heino, Mikko; Baulier, Loic; Boukal, David S.; Ernande, Bruno; Johnston, Fiona D.; Mollet, Fabian M.; Pardoe, Heidi; Therkildsen, Nina O.; Uusi-heikkila, Silva; Vainikka, Anssi; Arlinghaus, Robert; Dankel, Dorothy J.; Dunlop, Erin S.; Eikeset, Anne Maria; Enberg, Katja; Engelhard, Georg; Jorgensen, Christian; Laugen, Ane; Matsumura, Shuichi; Nussle, Sebastien; Urbach, Davnah; Whitlock, Rebecca; Rijnsdorp, Adriaan D.; Dieckmann, Ulf.
Biological reference points are important tools for fisheries management. Reference points are not static, butmay change when a population's environment or the population itself changes. Fisheries-induced evolution is one mechanism that can alter population characteristics, leading to "shifting" reference points by modifying the underlying biological processes or by changing the perception of a fishery system. The former causes changes in "true" reference points, whereas the latter is caused by changes in the yardsticks used to quantify a system's status. Unaccounted shifts of either kind imply that reference points gradually lose their intended meaning. This can lead to increased precaution, which is safe, but potentially costly. Shifts can also occur in...

FLR: an open-source framework for the evaluation and development of management strategies ArchiMer
Kell, Laurence T.; Mosqueira, I; Grosjean, P; Fromentin, Jean-marc; Garcia, D; Hillary, R; Jardim, E; Mardle, S; Pastoors, M.a; Poos, J.j.; Scott, F; Scott, R.
The FLR framework (Fisheries Library for R) is a development effort directed towards the evaluation of fisheries management strategies. The overall goal is to develop a common framework to facilitate collaboration within and across disciplines (e.g. biological, ecological, statistical, mathematical, economic, and social) and, in particular, to ensure that new modelling methods and software are more easily validated and evaluated, as well as becoming widely available once developed. Specifically, the framework details how to implement and link a variety of fishery, biological, and economic software packages so that alternative management strategies and procedures can be evaluated for their robustness to uncertainty before implementation. The design of the...

Reference points for predators will progress ecosystem‐based management of fisheries ArchiMer
Hill, Simeon L.; Hinke, Jefferson; Bertrand, Sophie; Fritz, Lowell; Furness, Robert W.; Ianelli, James N.; Murphy, Matthew; Oliveros‐ramos, Ricardo; Pichegru, Lorien; Sharp, Rowland; Stillman, Richard A.; Wright, Peter J.; Ratcliffe, Norman.
Ecosystem‐based management of fisheries aims to allow sustainable use of fished stocks while keeping impacts upon ecosystems within safe ecological limits. Both the FAO Code of Conduct for Responsible Fisheries and the Aichi Biodiversity Targets promote these aims. We evaluate implementation of ecosystem‐based management in six case‐study fisheries in which potential indirect impacts upon bird or mammal predators of fished stocks are well publicized and well studied. In particular, we consider the components needed to enable management strategies to respond to information from predator monitoring. Although such information is available in all case‐studies, only one has a reference point defining safe ecological limits for predators and none has a method to...

Scientific rationale and international obligations for protection of active hydrothermal vent ecosystems from deep-sea mining ArchiMer
Van Dover, C. L.; Arnaud-haond, Sophie; Gianni, M.; Helmreich, S.; Huber, J. A.; Jaeckel, A. L.; Metaxas, A.; Pendleton, L. H.; Petersen, S.; Ramirez-llodra, E.; Steinberg, P. E.; Tunnicliffe, V.; Yamamoto, H..
There is increasing interest in mining minerals on the seabed, including seafloor massive sulfide deposits that form at hydrothermal vents. The International Seabed Authority is currently drafting a Mining Code, including environmental regulations, for polymetallic sulfides and other mineral exploitation on the seabed in the area beyond national jurisdictions. This paper summarizes 1) the ecological vulnerability of active vent ecosystems and aspects of this vulnerability that remain subject to conjecture, 2) evidence for limited mineral resource opportunity at active vents, 3) non-extractive values of active vent ecosystems, 4) precedents and international obligations for protection of hydrothermal vents, and 5) obligations of the International Seabed...
