Making the Best of Invasive Species

Sometimes species are introduced to a new environment by mistake, and sometimes on purpose with the best of intentions. Often the unintended consequences are that the new species takes over and drives out native plants and/or animals because its natural controls are not in place in a different place. What to do? How about making the pest into the guest of honor at the dining table?
Take the Asian carp (please!). Imported from China in 1973 to clean algae from Southern ponds, the carp soon broke from their confines and infested Mississippi River waterways. Gobbling up the phytoplankton that support native species, the carp can grow four feet long and weigh 100 pounds. They continue to swim north and could establish themselves in the Great Lakes, the world’s largest freshwater system, and decimate native fish populations there.

Wildlife managers have tried to prevent Asian carp and other invasive species from reaching the Great Lakes by installing electric underwater fences and, occasionally, poisoning the water. But chefs from New Orleans to Chicago have also tried to put a dent in the population by putting the fish on their menu. Now, a researcher at the Aquaculture Research Center at Kentucky State University is trying to figure out how to harvest and promote carp as a food source. Currently, a few processing plants are converting Asian carp into ingredients for fertilizer or pet food. “That’s a shame, because the meat quality is excellent,” says Siddhartha Disgupta, an associate professor at the center.

Disgupta argues that the carp has all the health benefits associated with eating fish and, since it eats low on the food chain, has few contaminants such as mercury that tend to be concentrated in the flesh of other fish species. He says he’s eaten Asian carp in various preparations and found it delicious.

Smithsonian looks at several programs designed to get people to consume more invasive species as a way to either control them or make the best of a bad situation. Link

Asian Carp are being marketed as Silver Fin in many places or Kentucky Tuna even, if "Asian Carp" doesn't suit you. And they are best when filleted well to remove the bones (search Youtube for tips), and cooked very fresh. There are many other invasive species out there, and most taste pretty good. Give them a try!

I love to fish, and I love to eat fish, but I'm not about to eat a carp! Now, if they were to change its name to Asian Tiger Fish, or Freshwater Killer Shark, I'd be all over it.
I'd bet Bass Pro Shops could do some clever marketing and have thousands of rednecks with fishing gear swarming the Mississippi in no time.
