Ok, show of hands - how many know what endocrine disruptors are? Yeah we didn't either until North American Fisherman's Dr. Hal Schramm enlightened us.
They are the chemicals entering into our fisheries from a variety of sources; industry, agriculture, landscaping, even discarded pharmaceuticals. They disrupt the natural cycle of hormones, thus creating a wide range of abnormalities in humans, and enter through surface and ground water and can pose similiar risks to aquatic species.
While it's a complex issue, Hal offers a few suggestions for becoming aware of them and helping reduce their spread in the environment. It's good for the fish, and good for the fishing.
