Condition And Size Composition Effects On The Simulated Relationship Between Spawner Biomass And Total Egg Production For Northeast Arctic Cod (Gadus Morhua L.). ...
No abstracts are to be cited without prior reference to the author.Spawner biomass (SB) is often assumed to be proportional to total egg production (TEP) by fish stocks. Recent studies suggest that this assumption may not be valid, particularly when the physiological condition of fish varies. This s...
