Fisheries management has typically focused on the use of mathematical modeling to estimate current and future population trends to maintain the maximum sustainable yield in managed populations. However, modern advances in geospatial technologies and the emerging field of marine landscape ecology now provide landscape approaches and theory that can be applied in the management of marine fisheries. The use of landscape ecological approaches can provide important insights into the role that landscape complexity plays in the population dynamics and habitat requirements of commercially important species. Here, I review recent advancements in geospatial technologies and marine landscape ecology and their application to one experimental marine landscape study, and three studies dealing with managed fisheries populations across complex marine landscapes. I close with a discussion of emerging approaches in marine geospatial technology and how they may further enhance our understanding of the relationship of landscape complexity to the ecological dynamics of managed marine populations.
