Pharmaceutical contaminants discovered in South Florida bonefish

Quote:

A three-year study by FIU and Bonefish & Tarpon Trust (BTT) has discovered pharmaceutical contaminants in the blood and other tissues of bonefish in Biscayne Bay and the Florida Keys.

“Coastal fisheries face increasing threats associated with human-based contaminants,” said Jim McDuffie, BTT President and CEO. “Pharmaceuticals are an often overlooked dimension of water quality and their presence in South Florida bonefish is cause for concern. These contaminants pose a significant threat to the flats fishery, an important part of Florida’s recreational saltwater fishery, which has an annual economic impact of $9.2 billion and directly support over 88,500 jobs.”

Since the study began in 2018, FIU scientists and BTT research associates, in partnership with Sweden’s Umeå Unversity and the University of Agricultural Sciences (SLU), have sampled 93 fish in South Florida, finding an average of seven pharmaceuticals per bonefish, and a whopping 17 pharmaceuticals in a single fish. The list includes blood pressure medications, antidepressants, prostate treatment medications, antibiotics, and pain relievers. Researchers also found pharmaceuticals in bonefish prey — crabs, shrimp and fish — suggesting that many of Florida’s valuable fisheries are exposed, and not only the bonefish fishery.
