The prehistoric-looking alligator gar was once driven out of its native waters, but recent reports are touting the top level predator as a possible solution to the influx of Asian carp that are devastating local fish stocks. But could reintroduction actually work?

The Associated Press reports:

But the once-reviled predator is now being seen as a valuable fish in its own right, and as a potential weapon against a more threatening intruder: the invasive Asian carp, which have swum almost unchecked toward the Great Lakes, with little more than an electric barrier to keep them at bay.

Efforts are underway to reintroduce the alligator gar to the northern part of its former range.

Wherever ecosystems rich in species develop on the rocky shores of the Baltic Sea, the bladder wrack Fucus vesiculosus has provided perfect groundwork. By colonizing pebbles and rocks, it creates habitats for many other species. Other algae grow on the seaweed to be grazed by snails, isopods and amphipods. Crustaceans, mussels and predatory fish as well as many smaller organisms that are important for the Baltic Sea ecosystem thrive in submarineFucus forests. Fucus vesiculosus is one of the main producers of organic matter in the Baltic and plays a crucial role for its biodiversity and biogeochemical cycles. These functions could be lost due to a series of reactions triggered by climate change.
