Canada Greenland & Faroe Islands Russia Federal Research Centre for Fisheries, Hamburg/Germany (Co-ordination) Institute of Marine Research, Vigo/Spain Marine Research Institute, Reykjavík/Iceland University of Bergen, Bergen/Norway Institute of Marine Research, Bergen/Norway Close cooperation with: Tæt samarbejde med: EU REDFISH Project (2000-2003)

4.  Investigating the biology of redfish as a basis for fisheries management Undersøgelse af rødfiskens biologi som basis for fiskerimanagement 1. Species and population structure / Arter og populationsstruktur 3. Abundance and demography / Hyppighet og aldersstruktur 2. Reproductive strategies / Forplantningsstrategier EU REDFISH Project Project aims /Projektmål ? • Are there differences between species and stocks ? Er der forskelle mellem arter og bestande ? • When and where do redfish mature and bear larvae ? Hvornår og hvor sker rødfiskens modning og fødsel af larverne ? • How many eggs & larvae do female redfish have ? Hvor mange æg & larver har hunrødfisken ? • How are redfish distributed, and where being fished ? Hvor finds rødfisk, og hvor fiskes rødfisk ? • How old are these redfish ? Hvor gammel er disse rødfisk ?

5. 1. Species and population structure • Separation of species and stocks by different methods: Adskillelse af arter og bestande ved hjælp af flere metoder: 1.2 Otolith shape / Otolitomrids 1.3 Genetics Genetiske undersøgelser 1.1 Body shape / Kropsform

6. 2. Reproductive strategies 2.1 Investigation of female fecundity (number of eggs/larvae) Undersøgelse af hunfiskens frugtbarhed (antal æg/larver) 2.2 Reproductive cycle Reproduktionscyklus

7. 3. Abundance and demography • International database (research surveys, commercial fishery) International database (forskningstogt, kommerciel fiskeri) • Hydro-acoustic measurements of fish density Hydroakustisk målning af fisktæthed • Age determination and validation Aldersbestemmelse og validering
