摘要： Oyster reef habitats in estuarine areas are an important marine ecosystem globally. Due to the destruction of oyster reef habitats within the Luanhe River estuarine area, Bohai Sea, China, a local fisheries company created 2 km(2) of artificial oyster reef habitats by deploying artificial reef blocks that provided a settling surface for a natural oyster population and conducted sea cucumber aquaculture. The aims of this study are to help fisheries managers to understand whether the ecosystem function of created oyster reef habitat is consistent throughout the seasons and to assess if the current fishing production policy which varies with seasons is reasonable. We presented steady-state trophic models in different seasons of a newly created artificial coastal oyster reef within the Luanhe River estuary to address the above issues. We concluded that seasonality is an important factor that needs to be carefully considered in the fisheries management of oyster reef ecosystems.
