That's interesting because our company Habitat Solutions did over 2 miles of bank stabilization and habitat work on Wedge Creek which flows into Fountain Lake in Albert Lea. Just with the bank stabilization and habitat work alone sediment flowing into Fountain Lake from the once eroded banks in Wedge Creek was reduced by over 50%. I'm know there was a electric fish barrier built at the mouth of Wedge Creek because we were asked to bid on that project but that is not within our expertise so we declined.

An effective (but very controversial, to some), potential tool for actually ELIMINATING some invasive species is the use of gene drives. This involves genetic engineering where (for instance) ALL of the offspring (AND subsequent generations) of a species, like common carp, would be males. Eventually, the population becomes so skewed toward males that there are no longer ANY females left to produce eggs. Google it.

Of course, in the wrong application entire species could be eliminated (go extinct), but in controlled areas, like watersheds, and with invasive/destructive species (think deer ticks, carp, zebra mussels, etc), the benefits to Man and environment, as well as cost savings could be enormous.

Can this be rendered ineffective by a jerk carrying a few fish over and past the barrier?

I am thinking about the spread of asian carp and snakeheads from a few people intentionally releasing those fish in new waters.

Yes It can!!! Birds and other critters could easily cause a spread as well.

But because something COULD happen is that a good enough reason not to build it?
