Florida: fish positive for 17 different drugs

"The need for Florida to modernize statewide wastewater treatment plants. 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 lowland fishing, a major part of Florida's recreational saltwater fishing, which has an annual economic impact of $ 9.2 billion and directly supports over 88,500 jobs, "said Jim McDuffie, President and CEO of BTT.

But what happened?

A fish off the coast of Florida has been found positive for several drugs, such as antidepressants or others, such as those to fight blood pressure. It was precisely conducted by researchers from Florida International University and the Bonefish & Tarpon Trust (BTT).

The bonefish is a type of fish found in the Atlantic and Pacific oceans, while the tarpon is found in the Atlantic and Indo-Pacific. Jennifer Rehage, coastal and fish ecologist and associate professor at the University added: "These results are truly alarming.

Pharmaceuticals are an invisible threat, unlike algal blooms or murky waters. Yet these results tell us they are a formidable one. threat to our fisheries and highlight the urgent need to address our long-standing wastewater infrastructure problems."

About the bonefish

It is a tapered fish with a large head with an elongated snout on the lower part of which the rather small mouth opens.

The caudal fin is large and deeply forked, the caudal peduncle is quite thin. The fins do not have spiny rays but only soft: the dorsal fin and the anal fin are short, the anal is placed far back, close to the caudal peduncle.

The ventral fins are also inserted much posteriorly, under the dorsal fin; the pectoral fins are inserted at the bottom, near the ventral profile. The color is silvery with dark longitudinal lines similar to those of the common mullet.

The size reaches one meter per 10 kg of weight. This species is widespread only in American waters, both on the Pacific Ocean side (from California to Peru) and on the Atlantic side (from the southern USA to Brazil). It is very common in the Caribbean Sea and the Gulf of Mexico.

It populates very shallow coastal waters close to the coast on sandy or muddy bottoms, especially in areas with weak hydrodynamics such as gulfs and bays. Being euryhaline it also frequents estuaries.
