Technically no.Is there any such thing anymore?
Id just be overly cautious of storm drainages and eating frogs im guessing they absorb way more toxins than fish.

Frogs have lungs. They also absorb oxygen directly through their skins, and there are lots of capillaries and blood vessels beneath the skin, just as there are beneath the oxygen absorbing tissues in our lungs. But absorbing oxygen through their skin is only sufficient when there is plenty of oxygen in the water or the frog is inactive, such as when hybernating in winter. Frogs and other amphibians tend to absorb pollutants and chemical contaminants through their delicate skins. This makes amphibians the canaries in the coal mine when it comes to evaluating pollution. I recall reading a summary on the effects of Roundup on frogs. When Roundup is sprayed on fields at ordinary concentrations, it kills about 98% or more of the frogs in the ditches and waters receiving the runoff from the fields. Summary of many studies, many areas of the country, tracking the populations of different species of frogs. Didn't matter which frog species. Roundup killed nearly all of them. Interestingly, it isn't the glyphosate in the roundup that kills the frogs. Its one of the so-called "inactive" ingredients, a soapy substance used to make the Roundup stick to the plants. The summary was in a book titled The Truth About Organic Gardening.Iirc frogs also breath thru their skin, make certain you get them from a clean water source....
