Australia wants to give their carp herpes

Historically, these kinds of things have always gone terribly wrong for Australia. If it works for 95% or the carp, how do they keep the other 5% from rebounding? How do they keep them from forming resistance? If the virus emerged relatively recently in Israel, doesn't it stand to reason that it could mutate to infect other native fish? Do enough of the original species still exist to repopulate? If they are going to do it then they need a plan to get the 5% that still exist, like a GMO carp males that produce sterile offspring, though it might not work if multiple males spawn the same clutch.

They send their army to kill feral camels :biggrin:

Yeah, like I said it's not really set and forget. They'll have to coordinate a massive cleanup of all the dead fish to keep water oxygen levels from dropping while odor levels rise, and they'll have to introduce huge numbers of (previously) native fish in order to fill the gap. Even after all that, the 5% of survivors could conceivably outcompete all the local species again.

yeah, because when they did that with rabbits it totally worked.

That's just one example. There are many more. For example, they introduced a cactus for erosion control but it spread like crazy and ruined a huge amount of land, so they introduced a moth with caterpillars that destroy the cactus and now the moth thrives on native plants and crops.

The surrounding islands have many examples as well.
