According to a four-year study published on Wednesday by researchers at the University of California Los Angeles and Loyola Marymount University, nearly half of the fish served at more than two dozen highly-rated sushi restaurants in the city is mislabeled. Willette said the study, conducted between 2012 and 2015, looked at 26 sushi restaurants that were highly rated on the reviewing sites Yelp and Zagat. Biology students at UCLA were sent out to the restaurants over the four years to collect samples of 10 popular varieties of fish used for sushi. "I would say if you're going to a sushi restaurant, probably avoid the halibut and red snapper," he said. "Eat salmon because salmon is almost always salmon."
