Predation Mortality Calculation Plot abundance maps per predator, depth, month, year. 5 standard regions, 3 depth ranges Add distribution of prey Predator abundance x feeding rate = Predation Capacity for each station Adjust Predation Capacity for temperature effect & prey selection  to models Divide Predation Capacity by target prey abundance for Instantaneous Mortality Sum Instantaneous Mortality values for all co-occurring predators = total predation impact per prey species
