Channel Catfish ( Ictalurus punctatus ) By Josh Otten
Channel Catfish (Ictalurus punctatus) Also known as spotted cat, blue cat, river catfish, fiddler, willow cat Identification: skin instead of scales upper jaw longer than the lower jaw whiskers around mouth dorsal and pectoral spines are sharp and deeply serrated slender body/deeply forked tail anal fin curved/24-30 rays (blue has 30+) body is bluish silver on the sides and generally has dark spots shading to silvery white on belly

Channel Catfish (Ictalurus punctatus) can live as long as 25 years state record 36 pounds 8 ounces max 60 pounds (world record 58 pounds) Typical Adult Length: about 24 inches Weight: about 20 pounds Life span: about 11 years
Channel Catfish (Ictalurus punctatus) Habitat: found in most large streams, lakes, and many farm ponds prefer areas with deep water, clean gravel boulder substrates and low to moderate current tolerant of a wide range of conditions during the day found in deep holes with protection of logs and rock most movement occurs during feeding, around sunrise and sunset
Channel Catfish (Ictalurus punctatus) Distribution catfish
Channel Catfish (Ictalurus punctatus) Diet: use taste buds in the sensitive barbels and throughout the skin to locate prey primarily but not excessively bottom feeders omnivorous feeder/prefer smellier foods less than 14” primarily eat aquatic insect larvae and other invertebrates found on bottom over 14” primarily eat dead or alive fish also eat aquatic and terrestrial worms, frogs, crayfish, mollusks, mulberries, elm seeds and algae
Channel Catfish (Ictalurus punctatus) Reproduction: sexual maturity comes at five to eight years of age begin spawning when water temperatures reach 70 °F male channel cat builds a nest in underwater holes, logs or among submerged rocks use natural cavities, undercut banks and muskrat burrows as nests female lays a gelatinous mass containing between 8,000 to 15,000 eggs parents remain over the nest to fan the eggs and guard the young after hatching
Channel Catfish (Ictalurus punctatus) Conservation: none but raised in hatcheries and fish farms and distributed commercially Economic Importance: commonly in supermarkets and on restaurant menus heavily stocked in any water that will hold them important commercial fish considered one of the best-eating freshwater fish most familiar and popular catfish in North America Ecological Importance forages bottom, cleans up carrion eats smaller fish

Brown Bullhead (Ameiurus nebulosus, LeSueur) Chris Lee Iowa DNR Other common names:Bullhead, horned pout, red cat, creek cat, mud cat, speckled bullhead, and common bullhead. Other scientific names:Ictalurus nebulosus (Armstrong 1962).
Identification: Olive to brown with dark mottlings on sides fading to cream/white underneath. Fleshy whiskers (barbels) dusty to black. Relatively short anal fin with rays. Rear of caudal fin slightly notched. May be confused with Black bullhead, (Ameiurus melas). However, A. nebulosus has 5-8 large sawlike teeth on rear of pectoral spine whereas A. melas has none. Also, A. nebulosus does not have black membranes contrasting with pale rays on caudal and anal fins. Brown Bullhead (Ameiurus nebulosus) Brown bullhead Black bullhead
Distribution: Not common anywhere in IA, but is widely distributed in the northern part of the state. Very few found in interior waters. Most taken from the upper Mississippi backwater sloughs. A. Nebulosus is native and common to the Atlantic and Gulf slope drainages. Brown Bullhead (Ameiurus nebulosus) Habitat: Slow moving or stagnant parts of rivers, and streams, also ponds, lakes, and pools that offer a soft bottom. Diet: Brown Bullheads are schooling bottom feeders that feed primarily on crustaceans, insect larvae, worms, snails, crayfish, and small fish, though they will eat virtually anything available, either alive or dead. A large part of their diet is midgefly larvae, or “bloodworms” which they pick up off of the soft bottom ooze. Teeth in pads on both top and bottom jaws; used for tearing food. They seem to have ravenous appetites and will eat day or night. Iowa DNR
Brown Bullhead (Ameiurus nebulosus) Reproduction: Spawn in late April or May. Males fan out a saucer- shaped nest where females lay 2,000 to 10,000+ eggs that hatch in 5-8. Both parents guard the eggs during incubation and herd young around for several weeks after hatching. Young reach 2-1/2 – 4 inches in first year and mature in 3 years. Can reach two pounds. (IA Record: 2-1/2 pounds, no specific species given though. World Record: 6 lbs, 1oz., NY) Economic/Recreational Importance: Popular game species where they exist. Ecological Importance: Not much due to their lack of distribution and non-predacious lifestyle. Conservation Status: Abundant. Limit is same as catfish (?): DBL = 8 lake, 15 stream, PL = 30. No limit in Mississippi River. Other: Can reach 2+ pounds under ideal conditions, but most commonly range from inches and less than a pound Konrad Schmidt, University of Minnesota

Flathead Catfish Dark to olive-brown with dark brownish mottlings on the sides Tan to yellow colors on their ventral sides from swimming on sand and light bottoms The anal fin is very short with rays The head is broad and flat The lower mandible is longer than the upper unlike channels or blues Pylodictis olivaris Iowa DNR
Distribution/Habitat Where Can I find Flatheads: Submerged Brushpiles Logjams Slack Water just off main Channel Sandy Areas Distribution: Most of Iowa and its mid to large size rivers. Common in many other areas of the US also.
Diet/Reproduction Spawning occurs in June and July Flatheads are nest builders Grow 2-6 inches in the first year Sexually mature in their 3 or 4 year Adult diet consists usually of small to mid size fish Smaller fish eat crayfish and minnows
Conservation status Flathead Catfish are not protected in any way Are a popular recreational fish that are healthy in population numbers
Economic/Recreational importance Commercial fishermen along the Mississippi and Missouri rivers bring in $32,500 yearly from the Mississippi Flatheads are a highly sought after fish by Iowa Fisherman. Flatheadcat.com

Blackstripe Topminnow Fundulus notatus By Emily Mae Hoffman Ohio DNR
Identification Prominent black stripe from snout to caudal fin Flattened head and nape Silver-white spot on top of head Incomplete lateral line Epiterminal mouth with small teeth on both jaws Dorsal fin begins behind anal fin Adults are inches long, max. is 3 inches Illinois DNR
Habitat Small streams in Eastern Iowa Low current Travel in pairs Swim near water surface Iowa DNR
Diet Feed on water surface Aquatic and terrestrial insects Crustaceans Snails Algae Feed in morning, late afternoon, and evening
Reproduction Summer spawning season Male and female lay side by side on aquatic vegetation Female deposits eggs singly on aquatic vegetation eggs are deposited at one time, and is usually repeated after several days No further care is provided
Conservation Status Common in Eastern Iowa Population doubling rate of less than 15 months Can survive harsh environmental conditions due to breathing oxygen- rich surface water Is threatened in some states due to water pollution and habitat destruction University of Michigan
Ecological Importance Preyed upon by larger fish Known to jump out of the water to avoid predators Hide motionless in aquatic vegetation When feeding, their image reflects on the water surface. When a predator approaches, they dart one way and their image goes another way, which confuses the predator.

Brook Stickleback Habitat: Prefers moderate current; sand to gravel bottom; clean to slightly turbid waters Diet: aquatic insects, terrestrial insects, worms, snails, and sometimes fish eggs; occasionally algae What eats them: Brook Trout, Walleye, Basses, and fish-eating birds
Brook Stickleback Reproduction: Males build nests in late spring (May-June). Males secrete white cement chemical to attach nest to vegetation. The nest is made of organic material, algae, and other debris. Female releases eggs. Conservation: Brook Stickleback is not considered threatened or endangered. Ecological Importance: Serve as natural mosquito control
