Madagascar reckons with an invasive crayfish

The headline buries the lede about these things being able to self-clone hundreds of themselves every few months.

Yep, I think that part was the interesting bit here.

One of my early childhood memories was crayfishing. You can pretty much put anything on a string and these things will bite onto it. They are not picky. It's not even really fishing, it's almost as easy as just grabbing them from the water. It's a fun activity for kids because it doesn't require any skill to get good at.

They are an indicator species. They are not known for tolerating polluted bodies of water and quickly die if the water becomes toxic.

So their economy is now dependent on this newly acquired evasive specie. Very interesting article.

'In Mahasoa, nearly everyone participates in the crayfish economy in one way or another. People use them to fatten up pigs and chickens, or eat them with rice'

evasive != invasive

Crayfish are very good at hiding.

Once the ecosystem changes to a lower energy stable level, is basically inmutable. To revert it to its former rich energy state is practically impossible, even for humans. One of the laws of ecology.

All amphibians and fishes are now crayfish meat (and mosquitoes).
