Ecological carrying capacity in shellfish culture Operational models of carrying capacity applied to a Norwegian fjord

摘要

Estimation of production carrying capacity for shellfish culture has become a major focus inresearch, with operational models applied at culture sites worldwide. Fundamental to theseefforts are an understanding of the relationship between nutrients, primary production, andshellfish bioenergetics. The potential for manipulation of nutrients via artificial upwelling hasbeen undertaken in a Norwegian fjord in the CANO Project. Research in this area includesseveral types of models at varying spatial scales. One of the more useful configurations has beena box model allowing variation in the location of the upweller as well as the sites of musselculture. In a companion conference paper in by Filgueira and Grant, optimization routines areused to maximize mussel production in the upper fjord based on projected nutrientphytoplanktonenhancement by the upweller. The present paper considers the initial stages of afully spatial companion model where the results can be mapped in detail.
