Description:

The fallfish has a similar body shape as the creek chub, but is more laterally compressed and has a more pointed head.  Its back is dark olive, brown  to black in colour and its sides are silvery to a white belly.  The scales are large  with 43 - 50 along the lateral line.  Young fallfish generally have distinct mid-lateral  band.  They also have a dark pigmentation (cresent shaped) on the anterior edge  of its scales. The average length is around 5 inches, but the fallfish can grow  between 10 and 15 inches.

Biology:

The fallfish are commonly found in pools and runs of rivers, but are  also found in lakes.  Food consist mostly of aquatic insects, plankton, and other fishes.  The fallfish spawn in the spring.  Like creek chub males the male fallfish takes on a rosy colouration and develops tubercles on its head. The male creates a  depression for egg deposition by removing pebbles with its mouth.  The fertilized, non- adhesive eggs are then covered with gravel.  Commonly referred to as "chub" by anglers, fallfish are rarely kept for food.   They are preyed upon by fish-eating birds and larger fish.
