Natural mortality estimations for beaked redfish (Sebastes mentella) – A long-lived ovoviviparous species of the Northeast Arctic
Höffle, Hannes; Planque, Benjamin (Peer reviewed; Journal article, 2023)Beaked redfish (Sebastes mentella) is one of the few commercially important fish species producing living offspring. Like many other deep-water fishes, it is slow growing, late maturing and long-lived, getting as old as ... -
Non-deterministic modelling of food-web dynamics
Planque, Benjamin; Lindstrøm, Ulf; Subbey, Samuel (Journal article; Peer reviewed, 2014-10-09)A novel approach to model food-web dynamics, based on a combination of chance (randomness) and necessity (system constraints), was presented by Mullon et al. in 2009. Based on simulations for the Benguela ecosystem, they ... -
Now you see me, now you don’t: uncertainties in projecting spatial distribution of marine populations
Planque, Benjamin; Bellier, Edwige; Lasram, Frida; Loots, Christophe (Conference object, 2010-04) -

Plankton community structure and fish spawning area indicators in the Bay of Biscay, using Laser Optical Plankton Counter
Dupont, Nicolas; Planque, Benjamin (ICES CM Documents;2005/P:13, Working paper, 2005)In the Bay of Biscay, regular fisheries acoustic cruises are conducted to assess small pelagic fish stocks. Within the frame of the Bay of Biscay integrated project, measurements of additional biotic and abiotic variables ... -
Quantification of trophic interactions in the Norwegian Sea pelagic food-web over multiple decades
Planque, Benjamin; Favreau, Aurelien; Husson, Berengere; Mousing, Erik Askov; Hansen, Cecilie; Broms, Cecilie; Lindstrøm, Ulf Ove; Sivel, Elliot Manuarii (Peer reviewed; Journal article, 2022)While ecosystem-based fisheries management calls for explicit accounting for interactions between exploited populations and their environment, moving from single species to ecosystem-level assessment is a significant ... -
Quantifying diets for small pelagic fish: effects of weight versus occurrence methods and sampling effort
Mousing, Erik Askov; Planque, Benjamin; Arneberg, Per; Bjørdal, Vilde Regine; Keulder-Stenevik, Felicia Juanita; Liebig, Penny Lee; Mørk, Herdis Langøy; Skern-Mauritzen, Mette (Peer reviewed; Journal article, 2023)In the Norwegian Sea, assessment of diet composition relies on annual cruise activity combined with visual identification and weight determination of prey from fish stomachs. This weight-based method is labour intensive, ... -
Quantile regression models for fish recruitment–environment relationships: four case studies
Planque, Benjamin; Buffaz, Laure (Peer reviewed; Journal article, 2008-04-07)Understanding and modelling the environmental control of fish recruitment has been a central question in fish population ecology for the last century. Most environment–recruitment models have primarily been developed to ... -
