Journalist Rona Kobell takes the pulse of the aquaculture community and dissects conflicting messages from the White House. On one hand, Commerce Secretary Wilbur Ross wants to cut the seafood trade deficit and eliminate barriers for domestic aquaculture, but the proposed federal FY17 and FY18 budgets contain large cuts to aquaculture funding across NOAA and USDA.

Genetically modified (GM) salmon could be raised in Canada. AquaBounty, the company that sought and was awarded FDA approval to sell GM salmon produced in Panama, now wants to start raising the fish in their Prince Edward Island (PEI) facility. The PEI Salmon Council is concerned about this new development and is asking for a new federal risk assessment to be performed for the PEI facility. Read more at CBC News.
In a recent study, researchers purchased salmon from a fish market in Barcelona, Spain, and looked for a common sea lice drug called pyrethroid. They tested 39 farmed salmon raised in Alaska, Chile, Denmark, France, Norway, the Pacific Ocean, Scotland and Spain. All of the samples contained pyrethroid—but the researchers also wanted to know if the amount of drug remaining in the fish was a health risk for consumers. The drug was detected at mean concentrations of 1.3 ppb in fish tissue, which would provide estimated daily intake rates of 0.1 to 0.9 picograms (kg bw)−1 for consumers, which is 0.002% of the acceptable daily intake of pyrethroids [0.02 – 0.05 micrograms kg bw)−1 day]. Therefore, the researchers concluded that pyrethroid treatment of salmon does not pose a health risk to consumers. Read more at the journal Food and Chemical Toxicology.

We came across a must-read report called “Seafood in Europe—A Food System Approach for Sustainability,” led by Constança Belchior and Benjamin Boteler, and published in October 2016. The report is intended for policymakers, researchers and practitioners. Read more at the European Environmental Agency.
Writer Vinita Govindarajan covers the environmental damage done by shrimp farms in Tamil Nadu, India. Salination of groundwater by shrimp farms renders the drinking water unusable for locals, and even after the shrimp farms shut down and move on the soil is too saline for crops to flourish. Wonderful investigative reporting and photographs. We look forward to reading Part II in the series! Read more at Scroll.in.
A land-based recirculating aquaculture system (RAS) salmonid farm is coming to Wisconsin. The producers expect to raise 120,000 pounds of salmon and 40,000 pounds of trout a year, and the waste will be fed into a hydroponics system to grow leafy greens and herbs. What’s intriguing to us is the design of the system. This will be one of the first industrial-scale trials in which RAS waste will feed a hydroponics system. Read more at Aquaculture North America.
The Center for a Livable Future has two news releases out this month! One is about our recent paper analyzing federal aquaculture spending and return on investments, and the other is based on a commentary we wrote with NOAA scientists about aligning federal fisheries and health policies to advance health and fisheries sustainability goals. Read both of them at our website: federal aquaculture funding; seafood policy.
The state of Alaska is easing restrictions and providing seed to aquaculturists interested in aquatic plant and shellfish production. The statewide legislation received support from fishers, economic development groups and others. Read more at The Fish Site.
