Tianjin Fisheries Continue Using Illegal Chemicals Amid Dearth of Checks

(Beijing) — Many private fisheries in Tianjin’s Tanggu riverside district are using illegal chemicals to keep their farmed fish alive, a report said on Tuesday.

Commercial fish farms in Tanggu can contain up to 6,000 fish per acre, a fishery owner speaking under the pseudonym Chen Ming told the Beijing News. Fish reared in such crowded conditions are especially vulnerable to contagious diseases, so each farm receives seven or eight rounds of chemical treatments a year, Chen said.
