DIET: Steelhead feed on a variety of aquatic and terrestrial invertebrates and small fish. Unfortunately, steelhead are also very susceptible to hybridizing with other trout which might include non-native species. Missouri’s official state aquatic animal, the paddlefish is highly valued as a sport fish. Because they need lots of open, free-flowing rivers plus oxbows and backwaters for feeding and gravel bars for spawning, paddlefish numbers have declined with stream channelization, levee construction, and drainage of bottomlands. The trees have come to life a bit, and you can actually flip a few, squarebill a few, and sometimes whack em on a spinnerbait. We would like to show you a description here but the site won’t allow us.

Steelhead are one of the top five recreational fish species in North America. Unlike our plankton-feeding paddlefish, the Chinese paddlefish was a fish-eater. Spawning occurs in late spring at times of high water; eggs are deposited on silt-free gravel bars where, during regular water levels, they would be exposed to air or are covered by very shallow water. These two reproductive types are named “stream maturing” and “ocean maturing.” Steelhead can be grouped into winter or summer runs, depending on when the adults return to fresh water to spawn. It was native to the Yangtze and Yellow River systems in China (huge rivers that are similar to our Mississippi and Missouri rivers). The National Marine Fisheries Service (NMFS) has designated 12 distinct population segments of steelhead on the west coast of the United States.

Lurking among the plants in the water is a master hunter ready to pounce and devour an unsuspecting fish. Steelhead, the anadromous form of rainbow trout, are economically important as a commercial fishery and culturally important to Native American Tribes. Native populations of steelhead are threatened by habitat degradation, fishing pressure and diseases such as “whirling disease,” a parasitic disease that can cause skeletal deformities and death in young steelhead. Length: to about 7 feet; weight: to 160 pounds or more. The National Fish Hatchery System of the U.S. SIZE: Steelhead normally reach lengths of 24 in (61 cm) but have been reported reaching lengths of 45 in (120 cm). Channelization, damming, impoundments, and other river modifications have greatly diminished the habitat for this fish. There are no scales, except for a patch on the tail. Paddlefish have a long paddle-shaped snout and a sharklike body. Dams prevent paddlefish from being able to move upstream to their spawning territories, which prevents them from reproducing on their own.

Steelhead trout are migratory rainbow trout. The offspring of two steelhead parents may become a purely fresh water form of rainbow trout and the offspring of two freshwater resident forms of rainbow trout might evolve into the anadromous form of rainbow trout called “steelhead”.

The constant grazing of these fish on tiny aquatic organisms helps to keep their populations in check; paddlefish and their eggs and fry provide food for other aquatic predators. Paddlefish, also known as spoonbill, have long, paddle-shaped rostrums that are about one-third the length of their bodies. In regions with large infestations of the invasive zebra mussel, those mussels filter significant amounts of plankton out of the water, plankton that would otherwise feed native paddlefish. The Polyodontidae family of fish goes back to the Early Cretaceous, 120 to 125 million years ago, about the same time that flowering plants (angiosperms) appeared on Earth.
