Aquaculture is an important industry that is developing rapidly in temperate coastal regions worldwide. While soft-sediment impacts have been relatively well described, there is much less know regarding trophic interactions and how marine food webs may uptake and assimilate additional organic carbon loadings. As aquaculture continues to expand, a greater understanding of these trophic linkages is vital for sustainable development.
Sponges are sessile filter-feeders that are a ubiquitous feature on temperate reefs worldwide. They can be sensitive to organic enrichment, with increases in sedimentation potentially smothering sponges and limiting their capacity to feed and respire effectively. However, they also have the capacity to remove both particulate organic carbon (POC) and dissolved organic carbon (DOC) from the water column. With a high filtering capacity and association with diverse microbial communities, they are a key link in carbon flow from pelagic to benthic systems and a potential pathway for mitigating aquaculture waste into marine ecosystems. While the role of sponge communities in POC and DOC cycling in tropical reef systems is acknowledged, the capacity for this in temperate reef systems is less well understood. This PhD will explore the assimilatory capacity of temperate reef sponge communities and their potential interaction with finfish aquaculture.
