Improving bioremediation with extractive species in integrated aquaculture - Towards application in tropical recirculating systems


Faced with resource limitations and environmental regulations, aquaculture operations have to augment their output while decreasing the relative use of resources. Integrated aquaculture is seen as a strategy to meet demands for more efficient and sustainable aquaculture production. This thesis provides an example of IMTA with edible tropical species at three different trophic levels. A proof-of-concept tests the viability of a low-technology recirculating aquaculture system of fish, sea cucumbers and halophytes. Subsequent experiments applying different methods of stable isotope analysis investigate how the performance of the extractive species can be optimized to imporve the recovery of nutrients in intefrated aquaculture.
