Calculate biomass using the CPUE seabed area analogy
cpue_bio(fish_CPUE, fish_area, ref_CPUE, ref_area, ref_bio)
| fish_CPUE | CPUE data from the research area |
|---|---|
| fish_area | habitat area (km2) in research area |
| ref_CPUE | CPUE data from reference area |
| ref_area | habitat area in reference area |
| ref_bio | biomass estimate in reference area |
