Nile Perch vs Asian Carp or Lionfish or Green Crabs?

Nile Perch aren't picky eaters and are voracious predators. It would be worthwhile to conduct experiments on whether they would preferentially eat Asian Carp or other invasive species. The variety from Lake Maryut could be introduced to brackish waters and thence gain the ability to survive in the ocean.

Of course, a repeat of the rabbit or cane toad incidents in Australia is possible, but less likely in the ocean.
