1 IIFET 2014 Conference, 7-11 July 2014, Brisbane, Australia Exploring fisheries dynaics according to different quota governance echaniss: application to the bay of Biscay coon sole fishery Manuel Bellanger, Claire Macher, Mathieu Merzéréaud, Olivier Guyader IFREMER, UMR AMURE

2 Outline Introduction Governance syste of bay of Biscay sole quota Methods for ipact assessent and governance scenarios Preliinary results of bio-econoic ipacts of alternative governance systes Conclusions / perspectives 2

3 Introduction French context Gradual transfer of copetence (including quota anageent) to Producer Organizations (POs) Fishing rights are not transferable Evolution of quota anageent in response to constraining quotas => PO ergers & IQ systes 3 Issues addressed: understanding quota anageent syste evolutions and anticipating their bio-econoic ipacts What are the effects of quota governance on fisheries dynaics including distributive effects? Present work follows Macher et al where quota arkets were tested and investigates the effects of quota anageent by POs

4 Introduction Case study: bay of Biscay coon sole fishery 450 vessels > 1 Ton 1400 fisheren Landings = 4600 Tons (2011) GR 191 illion euros (2011) Other fleets 75 Nephrops trawlers Sole landings 2008 (projet Gepeto) France 161 Mixed botto trawlers Innovative quota anageent (IQ since 2006) 120 Sole gillnetters 34 Mixed gillnetters 4 Spain

5 Governance syste of bay of Biscay sole quota Meber State share based on a relative stability key Quota share by PO based on historical landings ( ) of their ebers. 5 Larabi et al Manageent by POs: collective and/or individual quota allocation based on a collective-pooling anageent syste specific for each PO

6 Governance syste of bay of Biscay sole quota Manageent by POs: Individual vs Collective quotas 2006: Individual Quotas = 20% TAC 2011: Individual Quotas = 65% TAC Evolution towards IQ systes as TACs becoe ore and ore constraining Adinistration s deands for ore transparency + PO ergers Probable hoogenisation of 6 PO Sub-groups Quota anageent Allocation criteria PMA Trawlers and gillnetters vessels Mean production by Individual quotas with production >2 t vessel Trawlers and gillnetters vessels Individual quotas Package of 2 t by vessel with production <2t Large gillnetters<18 Individual quotas Package of 18 t by vessel OPOB Large gillnetters>18 Individual quotas Package of 26 t by vessel Other fleets Collective quotas Noiroutier All vessels Collective quotas Vendée All vessels Collective quotas Yeu All vessels Collective quotas Fro Sud- Ouest Gillnetters fro royan fleet Other fleets Individual quotas Collective quota La Côtinière All vessels Individual quotas ArcaCoop CapSud Vessels outside the Arcachon Basin Vessels inside the basin Vessels targeting sole Other vessels by-catching sole Individual quotas Collective quota Individual quotas Collective quota Historical basis Historical basis and ean landings Max landings in the last 10 years by vessel Historical basis Quota anageent and allocation criteria by PO (2011) Map of Bay of Biscay POs (France)

8 Governance syste of bay of Biscay sole quota POs & ergers: In 2011: 9 POs operating in the Bay of Biscay On-going PO ergers Short ter probable situation 7

9 Methods for ipact assessent 1 An algorith for collective and individual quota allocations Adaptable rules by PO or by set of POs (erger) 2 An aged-structured bio-econoic odel: IAM (Macher et al. 2013) Multi-species, Multi-étier, vessel-scale odel Inputs files based on DCF data and stock assessent outputs Siulation/optiization The odel adjusts individual fishing efforts to atch quota allocations derived fro the algorith 8

10 Methods for ipact assessent Inputs: 392 vessels individually odelled (+ Fother fleets): effort, production and econoic costs structure Nephrops and sole paraeters for stocks dynaics Price for sole Quotas & sub-quotas by POs, vessels track records, PO eberships 9 Outputs: Indicators on the stock status: Bioass Fishing ortality Landings-Catches Indicators on the vessels activity Distribution of effort on étier sole for active vessels Indicators of econoic perforances (at fleet & vessel levels) Gross value added Gross cash flow

20 Preliinary results Overview Does the governance have the potential to soften the loss in a quota diinution context? In average: Yes In ters of variance: Yes as well! PO ergers & hoogenisation of quota : Who is winning? Who is losing? North bay of Biscay POs: large sole gillnetters (>16) would give up quota shares to sall gillnetters and to trawlers South bay of Biscay POs: soe would suffer fro ergers, and viability ay be a concern in a quota diinution context 16

21 Conclusion Results highlight inter- and intra-group differences in ters of effort and econoic perforances according to alternative governance scenarios Fleet structuration in ters of POs + their quota anageent systes have significant ipacts on fisheries dynaics Perspectives Developent of the governance odel: PO dynaics (ergers) and PO behaviour to be explicitely odelled 17 Modelling the behaviour of producers: etier choices, adjustent of capacity, copliance with rules
