Seafood may be contaminated with bacterial pathogens, such as vibrio and salmonella

New research by USC scientists shows domoic acid from ocean algae is a growing problem

About 25 percent of the world’s food supply is discarded or burned because of contamination or spoilage

Study finds retention of protein and calories in feed similar for major aquaculture and livestock species

"Mollusc shells are viewed by the aquaculture and seafood industries as 'nuisance waste' and largely disposed of in landfills", says researcher

The Centers for Disease Control and Prevention estimates Vibrio cause 80,000 illnesses and 100 deaths in the U.S. annually

The markers, called single nucleotide polymorphisms, are individual locations in the genome that, in this case, allow researchers to distinguish between the different variants of sockeye salmon

DNA barcoding analysis finds no evidence of seafood fraud; swaps are mostly with closely related species

The practice often occurs on the high seas and beyond the reach of any nation's jurisdiction

The research uses a new biophysical ecosystem model, based on simple metabolic principles and meticulously constrained with records of fish harvests provided by governments around the world
