tilapia

In recent years, as evaporation has taken its toll on the Salton Sea, its water has grown progressively saltier — too salty, in fact, for fish such as tilapia, an introduced species that previously provided an abundant food source for migrating birds.

Luke Nguyen’s Tilapia Fish Salad, from his cookbook "From China to Vietnam," is a masterclass in allium layering, using both fresh and fried red Asian shallots, as well as fresh and fried garlic.

Although red snapper is faring poorly in the wild, replacing it with tilapia is not helping snapper conservation.

Several examples of mislabelling involved substituting an expensive product for a cheaper species: tilapia for snapper, rainbow trout for Atlantic salmon.

For instance, a cheap fish like tilapia may be given the name of a more expensive fish, like red snapper, or an endangered species might be passed off as a better-faring alternative.
