New information about the factors that affect the dynamics of fish populations and new policies that expand the responsibilities of managers beyond single species are changing our attitudes of how we should be stewards of ecosystems. For example, there is accumulating evidence that climate, climate change and the ocean environment affect the abundance trends of commercially important fishes1 in a manner that we previously believed was exclusive to fishing impacts. This new information indicates that fish populations are affected by atmospheric impacts as well as by human interventions into their ocean habitats.
