The Area of Interest
Considered one of the seven forgotten wonders of the world, Niagara Falls is a breathtaking tourist destination. Located on the Niagara River, it acts as an international water barrier separating the United States from Canada. It is composed of two major sections, the Horseshoe Falls on the Canadian side, and the American Falls on the U.S. side. These two sections are separated by Goat Island, a popular destination on the American side accessible by foot, car or trackless train. It derives its name from a herd of goats that was kept on the island in the late 1700s, but due to an extremely harsh winter, only one goat survived. Also included in Niagara Falls is another smaller waterfall called Bridal Veil Falls. At its base is the Cave of the Winds which provides a protective barrier from the runoff - and is a very kitschy place for people to get married – hence its name. The name Niagara is believed to be derived from “Niagagarega” who were a local branch of the Iroquois Nation that resided in the area when French settlers arrived in the 1700s.

Gone Fishing – Invasion of the Snakehead
In the US we have seen our fair share of invasive species including the Peacock Bass that made its way from the depths of the Amazon River to waters of South Florida; or the wild boar that has all but taken over most of North America. Truth be told, you probably encounter many invasive species throughout your lifetime that have been around for so long that are, for the most part, now considered native, such as dogs, cats and even elk. But there is one creature that has sounded the alarm for concern and even panic, the freshwater snakehead.

So let’s take a step back and first come together on what exactly an invasive species is. An unofficial definition is a species that does not naturally occur in a specific area, and whose introduction does or is likely to cause economic or environmental harm. Well, we have hit the nail on the head with the snakehead. Normally native to Africa and Asia, this predatory fish not only breaths air but can survive on land for up to 4 days. The snakehead can migrate up to ¼ mile on wet land to other water bodies by wriggling their bodies and fins, giving way to their nicknames: Frankenfish or Fishzilla. With an appetite that spans from small fish to birds and reptiles to small mammals, this top-level predator has no natural enemies outside of their native environment which points to a disastrous future for our native aquatic species.
In the U.S., four species of the snakehead have been found in California, Florida, Hawaii, Maine, Maryland, Massachusetts and Rhode Island. While most cases involved a single fish, reproducing populations were found in Florida, Hawaii and Maryland. In one case in 2002, a pond in Maryland had to be poisoned after it was infested with snakehead fish. In October 2004, a snakehead was found for the first time in Lake Michigan, at Burnham Harbor in Chicago.
Most snakehead findings in the US have involved the northern snakehead, which is not known to be dangerous to humans. However, the giant snakehead, a tropical variety indigenous to Southeast Asia, has been found in waters in Maine, Massachusetts and Rhode Island. This species has reportedly attacked and even killed people who approached its young.
In 2002, the US Department of Interior banned the importation and transportation of live snakehead fish, or their eggs, considering them a potentially damaging form of wildlife; they also made possession of the snakehead illegal in 16 states. The hunt is on as many states and agencies are offering cash rewards for catching and killing these foreign fish; and please be warned if you do come across the sneaky snakehead DO NOT release it back into the water.
If for any reason you should catch a fish that looks like this immediately kill it and make sure that you notify the Department of Fish and Wildlife in your state. (Source: Associated Press)
