Abstract
The differing contribution of the wetland areas of seagrass, mangroves and saltmarsh to the commercial catch in estuaries were unraveled using step-wise regression of each wetland area against catch, and using existing knowledge of their importance. The areas of mangroves, saltmarsh and seagrass all made important contributions to the commercial catches. The areas of each wetland developed within the estuaries are proxies for estuarine production of food that supports the fish catch, suggesting that the fish catch is related to the productivity of the estuaries. The estimated catch was about 15% lower than the reported catch, apparently due to contribution of the microphytobenthos to the estuarine production by "bare' areas. The catch in the Port Stephens Marine Park was lower than predicted, apparently due to increased management relative to the other estuaries. Mangroves are potentially more important to the commercial fish catch than currently understood.
