Titre Robbing Peter to pay Paul: replacing unintended cross-taxa conflicts with intentional tradeoffs by moving from piecemeal to integrated fisheries bycatch management Type Article scientifique

Résumé 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 seine, gillnet and trawl fisheries. We identified priority improvements in data quality and in understanding ecological effects of bycatch fishing mortality to support holistic ecological risk assessments of the effects of bycatch removals conducted through semi-quantitative and model-based approaches. A transition to integrated bycatch assessment and management that comprehensively consider biodiversity across its hierarchical manifestations is needed, where relative risks and conflicts from alternative bycatch management measures are evaluated and accounted for in fisheries decision-making processes. This would enable managers to select measures with intentional and acceptable tradeoffs to best meet objectives, when conflicts are unavoidable.

Titre The 'new' European fish culture systems: Recirculating systems, offshore cages, integrated systems Type Article scientifique
Année (down) 2009 Publication Cahiers Agricultures Revue Abrégée
Volume 18 Numéro 2 Pages 227-234
Mots-Clés Pisciculture; Offshore structures; Integrated management; Fish cages; Europe
Résumé Over the last few decades, European fish culture was developed mainly as a intensive monospecific activity. In most countries, marine aquaculture cannot continue to develop on the shore line where it first settled due to high competition with other activities. It has now to move either offshore or into recirculation systems located in less occupied spaces. Fresh water availability and impact of fish production farms on the environment are strongly restraining the development of the activity, which is even declining in some countries such as France. Recirculation systems make it possible to decrease water consumption and facilitate waste treatment. Their economical feasibility is being demonstrated and they offer an alternative to developing fish farms. Whatever the rearing system, nutrients of feed are partially converted into fish flesh and most of them are thrown back as wastes into the environment. Integrated systems make it possible to convert such nutrients into algae, molluscs or fish and to release purified water. This article presents some aspects of the development of three types of rearing systems which are increasingly used in northern Europe: offshore cage culture, recirculation systems and integrated systems.
