A study of Spanish Greenland halibut commercial effort and CPUE in 3LMNO using GIS with comparisons to the Spanish Div. 3NO survey and EU Flemish Cap survey catches
An analysis of commercial CPUEs of Spanish commercial Greenland halibut fishery at depths of more than 700 meters is presented in this paper. We use percentage of effort from NAFO observers and CPUEs from IEO (Instituto Español de Oceanografía) observers. A GIS analysis was used in order to see how...
