"...worse than an oil spill, because we can clean that up"

The Mozambique tilapia (Tilapia mossambica) may be catch-of-the-day in many restaurants, but on the island of Palau, it's poisson-non-grata. As reported by Channel NewsAsia, officials have eradicated almost 30,000 of them, out of concern for the likelihood of their escape into the natural environment. Tilapia are considered invasive in many parts of the world, and are thought to be a major threat to Palau's native fish populations. Looks like Palau's poison of choice is rotenone...couldn't they just have had an island-wide fish fry?
