Grass carp used to clean Phoenix canals overeating, growing by leaps and bounds

PHOENIX — Officials say the fish they use to help clear algae and weeds from Phoenix canals are overeating and getting even bigger.

The Arizona Republic reports Salt River Project crews use about 50,000 white amur fish, or grass carp, a species native to China, to help clean the canals. The crews drain portions of the major canals each year so they can repair cracks, remove trash and clear debris.

Crews have to move the fish to properly repair and clear the canals. But Salt River Project spokesman Jeff Lane says the fish recently pulled out of the canals measure between 40 and 45 inches. He says they’re typically around 30 inches.

SRP says the dry-up is scheduled to run through Feb. 5.
