'Hairy crab' threat to Scottish fish (BBC) {invasive species}
An invasive crab species discovered in a Scottish river could have a "devastating impact" on salmon and trout if it spreads, experts warn.
The remains of a Chinese Mitten Crab - also known as "hairy crab" - were found in the Clyde in June.
Scientists have warned the crabs will eat fish eggs if they spread to areas where trout and salmon spawn.
The Mitten is classed as one of the top 100 worst alien species and threatens biodiversity.
It preys and on native species and causes severe structural damage to riverbanks.
