White Sucker (Catostomus commersonii)

white_suckerThe White Sucker is a bottom feeding fish, preferring shallow and warm waters.  They are known by many other names including things like mullet, common sucker, mud sucker, coarse-scaled sucker, June sucker, brook sucker, gray sucker, sucker, black mullet, slender sucker, and white horse.  Whatever name they are known by, these fish spawn in the spring among pebble and gravel beds in the shallows.  Both male and female suckers can become sexually mature at anytime between 3 years of age to 8 years of age, however, female suckers tend to grow faster, grow larger, and live longer than males.  On average however, the white sucker grows to be 12-20 inches long, and rarely lives over the age of 17. 

Under 12 inches in length, white suckers are vulnerable to bass, burbots, walleyes, northern pike, and muskellunge.  White Sucker fry however is also vulnerable to fish-eating birds, and Atlantic Salmon.  White Suckers themselves are bottom feeders as mentioned before, and so only eat algae, aquatic animals, and small invertebrate animals, worms and crustaceans especially.
