Book excerpt: Traditional approaches to research and management of striped bass have tended to be mechanistic, numerically oriented, and based on limited life history information. In the study presented here, comprehensive conceptual perspective was used in a multivariate study of life history and evolutionary adaptation of 10 striped bass populations representing the full geographic and ecologic diversity of striped bass. The colonization trajectory of populations originating from a small colonizing population from the Hudson River demonstrated how striped bass adapted in varying degrees of success in their reproduction, development, behavior, survival, and trophics to a range of western North American habitats. Habitats that were marginal through infrequent suitability for successful reproduction or survival of early life stages, or through limiting longevity, resulted in life history tactics that consisted of tradeoffs between life history traits, especially reproduction and development. Fishery management effects (exploitation and stocking) and habitat effects (water temperatures, freshwater inflows, forage and pollutants) influenced life history and evolutionary adaptive capacities of all populations. Highly variable and indeterminate environments also affected these capacities and related to year-class dominance. This helped to explain declines in five of the study's populations.
