Utah Lake Mullet 



In the spring of the year, as the spawning season approaches, 

 they run up the streams in great numbers and spawn upon the

Catostomns ardcns Jordan & Gilbert 



This species is very close to the common sucker, differing 

 chiefly in the larger mouth and lips. Abundant in the Snake 

 River basin above Shoshone Falls and in the lakes and streams 

 of the Great Salt Lake basin. It swarms in myriads in Utah 

 Lake, "the greatest sucker pond in the world." In Heart Lake of 

 Yellowstone Park this fish is infested by a parasitic worm (Ligula 

 catostoini) which is often larger than the fish's viscera. 



Like all other suckers, this species is a spring spawner, and 

 at that time immense numbers are said to come into the shallow
