Earlier this month, thousands of Atlantic salmon escaped a net pen in Washington state, raising concerns from environmentalists and questions about farming non-native species. Here are some answers.
The invasive species have been caught mere miles from Lake Michigan. Scientists fear if they invade the lake, they could spread throughout the Great Lakes.
Because demand for seafood is rising and wild stocks are not, a hatchery owner in Canada is hoping his model of "responsible agriculture" can keep the prized fish both on the menu and in the water.
In order to investigate how eating fish affects our health as well as the oceans, author and fisherman Paul Greenberg spent a year eating fish every day.
