Assessing the risk of vulnerable species exposure to deepwater trawl fisheries: the case of orange roughy Hoplostethus atlanticus to the west of Ireland and Britain ArchiMer
Dransfeld, Leonie; Gerritsen, Hans D.; Hareide, Nils R.; Lorance, Pascal.
With slow growth rates, late maturity and a high maximum age of 100 years or more, orange roughy can be classified as a vulnerable deepwater fish species that can only sustain low rates of exploitation. Historical patterns of exploitation associated with this species suggest that it is currently not possible to manage its fisheries in the Northeast Atlantic sustainably, and the total allowable catch for orange roughy has been gradually reduced to zero for European fisheries since 2010. Orange roughy to the west of Ireland and Britain occurs on distinct bathymetric features (seamounts, hills and canyons) as well as on flat ground along the continental slope. Productivity-susceptibility analysis (PSA) was performed to evaluate the biological vulnerability of...

Strengths and Weaknesses of the Management and Monitoring of Deep-Water Stocks, Fisheries, and Ecosystems in Various Areas of the World-A Roadmap Toward Sustainable Deep-Water Fisheries in the Northeast Atlantic? ArchiMer
Large, Philip A.; Agnew, David J.; Alvarez Perez, Jose Angel; Barrio Frojan, Christopher; Cloete, Rudi; Damalas, Dimitrios; Dransfeld, Leonie; Edwards, Charles T. T.; Feist, Stephen; Figueiredo, Ivone; Gonzalez, Fernando; Gil Herrera, Juan; Kenny, Andrew; Jakobsdottir, Klara; Longshaw, Matt; Lorance, Pascal; Marchal, Paul; Mytilineou, Chryssi; Planque, Benjamin; Politou, Chrissi-yianna.
Scientific interest in deep-water marine resources has increased dramatically over the last 10-20 years as management bodies have sought advice on how to manage deep-water fisheries and protect deep-water ecosystems. The strengths and weaknesses of the management and monitoring of deep-water stocks, fisheries, and ecosystems in various areas of the world are described, with the objective of informing the EU FP7 DEEPFISHMAN project so that it can fulfill its primary aim, which is to develop strategic options for a short-and long-term management and monitoring ecosystem-based framework for the northeast Atlantic. To provide a baseline, the current monitoring and management regime in the northeast Atlantic is reviewed, followed by a brief description of the...
