  1. From Trawl to Pots: an Analysis of Gear Shift in Norway Lobster (Nephrops) Fisheries Claire Macher1 Guyader, O. Talidec, C. Thebaut, O. Bertrand Le Gallic2 1. UMR AMURE, Ifremer, France 2. UMR AMURE, Université de Brest, France

  2. Introduction • Norway Lobsters (Nephrops) bottom trawling fisheries  High levels of joint productions (by-catches, discards) High social costs • Make management more complicated (right based management is difficult to implement in a joint production context) • High incentives to circumvent selectivity measures in the framework of a non cooperative game • High production costs

  3. Introduction • Objective: analysing the consequences of gear shifting (pots) in both value chain and environmental impacts • Presentation of the the Loch Torridon fishery (film) • Comparison with the Nephrops trawl fishery in the bay of Biscay.

  10. 1. Comparison between the 2 fisheries

  11. 1. Comparison between the 2 fisheries

  12. Landings distribution per age groups and correspondence between grades and age groups

  13. Nephrops pot might be both a profitable and a very selective gear when used in adequate regulation system

  14. Fuel cost increase favours alternative gear

  15. Concluding remarks • Higher ex-vessel price • Reduced operating costs • Improve fishers revenues • Improve rent generation / value chain • Potting instead of trawling can be a profitable activity (individually and socially) • But • Competition for stock and space Spatial incompatibility between these two metiers • Short term losses of the gear change and social cost of the status quo  question of financial support to gear change, could be legitimate in this case
