Project Description The overall goal of this project is to develop value-added products from invasive green crabs. Researchers are working on identifying and extracting functional ingredients and/or bioactive proteins and compounds from green crab biomass that would identify the crab as a useful species. Specific goals for green crab research: To develop appropriate methods to […]

Project Description Arctic surf clams are a commercial species only in Atlantic Canada, although their distribution ranges from Rhode Island to Labrador. Researchers have been culturing this species, Mactromeris polynyma, at UMaine–Machias’ Marine Science Field Station at the Downeast Institute since 2012, thanks to an NSF grant (PFI-BIC: Award # 1317268). While project personnel have […]

Project Description Sugar kelp is a globally important seafood and a nutritious source of dietary fibers, vitamin C, vitamin K, iron, calcium, magnesium, and iodine. Apart from dietary value, kelp is extensively cultivated for polysaccharides such as carrageenan, alginates, and fucoidan, which are used in emulsifying, food thickening, cosmetics, and the paper industry. The quality […]

Project Description Marine biofouling on aquaculture infrastructure increases fuel and maintenance costs for the aquaculture industry. Current methods to prevent biofouling do not fully prevent organism attachment or use chemicals that are toxic to biofouling organisms as well as other marine life. Cellulose nanofiber (CNF) is a non-toxic material that is economically available at a […]

Project Description Some harvested seaweeds are not suitable for sale to the food market, either because of contamination, biofouling, or aesthetic flaws. One way to derive value from such harvests could be to use the seaweed as a source of extracted compounds, such as polysaccharides, which have valuable properties for nutritional, chemical, and material applications. […]

Project Description Marine biofouling on aquaculture infrastructure increases fuel and maintenance costs for the aquaculture industry. Current methods to prevent biofouling do not fully prevent organism attachment or use chemicals that are toxic to biofouling organisms as well as other marine life. New methods are needed to effectively prevent biofouling in an ecological manner. To […]

Project Description This study evaluates the production efficiency of New England’s oyster aquaculture industry. A mixed mode survey has been designed and implemented to collect information from oyster growers in the region. This survey was sent to 530 oyster farming businesses located throughout Maine, New Hampshire, and Massachusetts. Growers were asked about their production methods […]

Project Description Social acceptance is a major component in slowing the growth of the U.S. marine aquaculture industry. One of the principal concerns that is frequently heard during lease hearings, is that property values will be adversely affected if a nearby aquaculture farm is allowed to develop. Unfortunately, there are few, if any, analyses of […]

Project Description This study assesses the market integration of domestically produced and imported catfish products in the United States. In 2003, the US adopted legislation that established anti-dumping tariffs for Vietnamese catfish products entering the country. One goal of this analysis is to determine how these tariffs have impacted the relationship between foreign and domestically […]
