Narrow-clawed crayfish (Astacus leptodactylus)
Narrow-clawed crayfish, also known as Turkish crayfish, are found at sites scattered throughout England after being originally introduced to the fish market in the 1970s. They are largely present in the midlands and south-east England including London. They originate from Eastern Europe and do not occur naturally in the UK. Narrow-clawed crayfish have the potential to outcompete the White-claws and can cause angling nuisance but like White-claws they are susceptible to crayfish plague and pollution.
| FACTFILE: The Narrow-clawed crayfish has a long thin body and on average reaches 15cm in length, they are usually olive-green to honey-brown and may be mottled, their joints are often dark orange. Blue varieties of Narrow-clawed crayfish are known. Their claws are very unique with long straight “fingers”. |
