Recent decline of New Hampshire’s iconic groundfish industry has created hardships for local fishermen. The few fishermen that remain are currently contemplating alternative sources of income through shellfish aquaculture, seaweed farming or integrated multi-trophic aquaculture (IMTA). Funded by NOAA Sea Grant, the University of New Hampshire has been developing IMTA approaches for Steelhead trout (Oncorhynchus mykiss), Blue mussels (Mytilus edulis), and Sugar kelp (Saccharina latissimi). The benefit of this culture method is the lower trophic shellfish and seaweed species bio-extract nutrients generated from the fish to reduce Nitrogen input to the environment. They also provide extra income to the farmer and better utilize the 3D farming space of a permitted site. A new winter growout model was demonstrated in 2021 with trout survival of 95%, FCR of 1.2:1 and growth from 150g to 1.85kg in 7 months. Economics of the system are underway and will become available to help fishermen and entrepreneurs adopt this new technology in the Gulf of Maine.
