Balanced harvest in the real world. Scientific, policy and operational issues in an ecosystem approach to fisheries ArchiMer

M.; Atcheson, Megan; Bartley, Devin; Borges, Lisa; Bundy, Alida; Dagorn, Laurent; Dunn, Daniel C.; Hall, Martin; Heino, Mikko; Jacobsen, Brigitte; Jacobsen, Nis S.; Law, Richard; Makino, Mitsutaku; Martin, Felix; Skern-mauritzen, Mette; Suuronen, Petri; Symons, Despina.
The concept of the Ecosystem Approach has entered the fishery harvesting discussions both from fishery perspectives (Reykjavik Declaration; FAO 2003 Annex to the Code of Conduct and from the principles of the Ecosystem Approach adopted by the CBD in 1995. Both perspectives establish the need to maintain ecosystem structure and functioning, whether for sustainable use of biodiversity (CBD) or simply to keep exploited ecosystems healthy and productive (fisheries). In response, the “Balanced Harvest” (BH) concept was suggested by a group of scientists brought together by the IUCN Fisheries Experts Group during the CBD CoP 10 in 2010. The meeting and the BH concept as consolidated there highlighted some of the collateral ecological effects of current fishing...

Robbing Peter to pay Paul: replacing unintended cross-taxa conflicts with intentional tradeoffs by moving from piecemeal to integrated fisheries bycatch management ArchiMer
Gilman, Eric; Chaloupka, Milani; Dagorn, Laurent; Hall, Martin; Hobday, Alistair; Musyl, Michael; Pitcher, Tony; Poisson, Francois; Restrepo, Victor; Suuronen, Petri.
Bycatch in fisheries can have profound effects on the abundance of species with relatively low resilience to increased mortality, can alter the evolutionary characteristics and concomitant fitness of affected populations through heritable trait-based selective removals, and can alter ecosystem functions, structure and services through food web trophic links. We challenge current piecemeal bycatch management paradigms, which reduce the mortality of one taxon of conservation concern at the unintended expense of others. Bycatch mitigation measures may also reduce intraspecific genetic diversity. We drew examples of broadly prescribed ‘best practice’ methods to mitigate bycatch that result in unintended cross-taxa conflicts from pelagic longline, tuna purse...

Selective fishing and balanced harvest in relation to fisheries and ecosystem sustainability. Report of a scientific workshop organized by the IUCN-CEM Fisheries Expert Group (FEG) and the European Board of Conservation and Development (EBCD) in Nagoya (Japan) 14-16 October 2010 ArchiMer
Garcia, Serge; Kolding, Jeppe; Rice, Jake; Rochet, Marie-joelle; Zhou, Shijie; Arimoto, Takafumi; Borges, Lisa; Bundy, Alida; Dunn, Daniel; Graham, Norman; Hall, Martin; Heino, Mikko; Law, Richard; Makino, Mitsutaku; Rijnsdorp, Adriaan D.; Simard, François; Smith, Anthony D.m.; Symons, Despina.
The conventional selectivity paradigm is briefly reviewed and its performance examined from an ecosystem perspective. It is stressed that the overall (cumulative) selectivity of the harvest process in an ecosystem is the result of nested selection by fishers and fisheries of: (i) habitats; (ii) species assemblages; (iii) populations and (iv) individuals. A range of ecosystem models predict a strong impact of concentrated fishing (selective fishing) on the ecosystem structure stability, resilience and productivity. There seem to be advantages (in both yield and maintenance of ecosystem structure and functioning) to distribute fishing pressure broadly across available species and ecosystem compartments. Balanced harvesting was therefore defined by the...
