excerpt:
In parts of rural Mexico, the invasive diablo – devil – fish, a brown, ugly creature with spines, had all but blotted out the bottom of creeks, rivers and wading pools.
The fish choked off native species like mojarra, which is popular on dinner tables, and made it all put impossible for Mexican fisherman to make their livings. Every time they put their nets into the water, they’d pull out dozens of diablo fish, and maybe one or two mojarra.
