An emerging issue in the science of whales is the role of whales in the ecosystem. When stomach contents were analyzed as part of the scientific whaling programs, it was found that baleen whales eat a large amount of commercially important fish . Clearly, when conservation requires a reduction in fishing effort or the number of fishing vessels in order to realize the recovery of fishery resources, we need to consider whether the consumption of these resources by whales undermines such efforts. Fisheries management organizations including the United Nations FAO are increasingly expressing the need for an ecosystem approach to fisheries management .
