Integrated Multi-Trophic Aquaculture in the Gulf of Maine

Muscles and seaweed in Aquafort

 

Please join the University of New Hampshire for a 10-part learning series on integrated multi-trophic aquaculture (IMTA) approaches in the Gulf of Maine.

When:

March 22 – April 21, 2022. Twice a week: Every Tuesday and Thursday afternoon from 4:00-5:00 p.m. over the 5-week period. See complete schedule of dates and topics below.

Series Format:

Each 1-hour session will be presented via Zoom (virtual/online). Expert speakers will discuss different aspects of IMTA farming –from site permitting to harvest of seafood products to the economics of the business. Q&A will be encouraged.

More about IMTA:

Researchers at the University of New Hampshire have been developing integrated multi-trophic aquaculture (IMTA) approaches for steelhead trout (Oncorhynchus mykiss), blue mussels (Mytilus edulis), and sugar kelp (Saccharina latissima) on a nearshore, floating platform since 2010. In this aquaculture system, the shellfish and seaweed species are suspended around the fish nets, which hang from the inside of the floating platform structure. Shellfish and seaweed bio-extract nutrients generated from the fish to reduce Nitrogen and Phosphorus input to the surrounding marine environment. The additional species provides extra income to the farmer and better utilizes the entire culture space.

In 2018, NOAA’s National Sea Grant Office awarded UNH research funds to further develop the IMTA system into what we now call the AquaFort. This uniquely engineered system is robust and can withstand 4 m (13 ft) waves, strong currents, and culture the three species together in a semi-protected site. Recent research results suggest a winter grow-out of the steelhead trout from 150g to 2kg can be obtained in 9 months with survival rates of 87% and a feed conversion ratio (FCR) of 1.2:1. Economics of the system are underway and will be shared with fishing/aquaculture industry members, students, and entrepreneurs that may have interest in this new technology.
