Using stable isotopes in mangrove fisheries research--a review and outlook

Mangrove forests are important coastal wetlands in most of the tropics, but their importance to fisheries is poorly understood. Rationales for conserving these ecosystems are partly based on ideas that mangroves are important to food webs that support fisheries. Here we review use of stable isotopes to test the strength of the mangrove forest-fish connection, suggesting that a dual focus on both food web ecology and habitat use may be most profitable in future studies of this type.
