Ø.(1997): MULTSPEC - A Multispecies Model for Fish and Marine Mammals in The Barents Sea
A detailed description is given of MULTSPEC, which is an area, age and length structured multispecies simulation model for the species capelin (Mallotus villosus), her-ring (Clupea harengus), cod (Gadus morhua), harp seal (Phoca groenlandica) and minke whale (Balaenoptera acutorostrata) in the Baren...
