Abstract: Ecosystems are not closed, but receive resource subsidies from other ecosystems.

Energy, material and organisms are moved between systems by physical vectors, but migrating

animals also transport resources between systems. We report on large scale energy transport from

ocean to coast by a migrating fish population, the Norwegian spring-spawning (NSS) herring Clupea

harengus. We observe a rapid body mass increase during parts of the annual, oceanic feeding

migration and we use a bioenergetics model to quantify energy consumption.
