New Hampshire IMTA Study Shows Oysters Reduce Nitrogen in Shrimp Farming

New research out by graduate student and scientist Elizabeth Martin with funding support from both the UNH Center for Sustainable Seafood Systems and UNH College of Life Sciences and Agriculture, advised by Michael D. Chambers, with Dave Fredriksson, Mike Coogan and Chris Neefus. Lizzy studied nitrogen production from shrimp with corresponding nitrogen uptake rates with gracilaria (instead of using a biofilter). She also investigated treatments with oysters.

Deep Water Seaweed Farming Successful Technology Demonstration in Maine

Members of the CSSS, Michael Chambers, Zach Moscicki, Rob Swift and Igor Tsukrov collaborated with Umaro Foods, Otherlabs, Kelson Marine and Stationkeep LLC to design and test a resilient, low-cost system for growing macroalgae (a.k.a seaweed) at large scales in the open ocean environment. The project is funded by the US Department of Energy ARPA-E’s MARINER program, which aims to encourage technologies that could someday support a macroalgae based biofuel industry. This presentation serves as summary of the key project objectives.

Aquaculture Research at UNH:
Using Fish Physiology to Help Growers of Commercially Important Species

The work done in the Berlinsky Lab at UNH helps to improve the cultivation of commercially important finfish species by understanding and ultimately controlling physiological processes. For example, by understanding reproductive processes, researchers can control the timing of fish breeding, alter the ultimate sex of fishes in an aquaculture system, and enhance egg quality.

Graduate Student Feature: Gender Equity in Aquaculture

Graduate Research Fellow and former intern of Michael Chambers, Natalie Lord, researched the gender norms of the aquaculture industry. Entering into a previously male-dominated sector has often been a challenge for women and they are working hard to dismantle the perceptions of traditional roles for women in the maritime sector.

Open Ocean Aquaculture symposium presentation

On October 6, 2022, Michael Chambers joined a team of aquaculture experts presenting material at the Commonwealth of the Northern Mariana Islands (CNMI) Offshore Aquaculture Symposium. The goal was to initiate a new aquaculture industry that would create seafood security for the local population and provide opportunity to export seafood to other Pacific Islands. Dr. Chambers presented on behalf of the CSSS with a focus on how his Integrated Multi-trophic Aquaculture (IMTA) work can be applied for island communities.

Aquaculture Research at UNH:
Using Lumpfish in Aquaculture Production

The University of New Hampshire has been working with the New England aquaculture industry (salmon farmers in Maine and steelhead trout farmers in N.H.) to promote the use of cleaner fish in salmonid cage culture to control parasitic sea lice in a more environmentally friendly and natural way.

Oyster farmers raising awareness of industry with Oyster Fest

Oyster Week 2022 closed with Oyster Fest at Bernie's Beach Bar in Hampton. The event showcased music, drinks and all-you-can-eat oysters from six local farmers. The New Hampshire Shellfish Farmers Initiative organized the event and is made up of all 14 oyster farmers in the Seacoast. Organizers want people to know the environmental and economic benefits of oyster farming.

UNH Receives $5M to Expand Its Commitment to Sustainable Seafood

Thanks to a $5 million gift, the University of New Hampshire will transform and expand its existing open ocean aquaculture site into the UNH Sustainable Seafood Field Laboratory. This first-of-its-kind field lab will provide the critical data needed to monitor local environment conditions and the aquaculture system’s impact on natural fisheries.
