Facts About Tiger Trout

| Updated September 26, 2017

The tiger trout is a kind of fish that is born due to the breeding of male brook trout with female brown trout. The hybridization process occurs when the male sperm is fertilized with the female eggs. The sterile game fish is known scientifically by the name of Salmo trutta x Salvelinus fontinalis.


The tiger trout has a grayish-brown body that is covered with a dark pattern which resembles a labyrinth. The fish has a square tail fin and a bright belly that is a blend of orange and yellow. The pelvic and pectoral fins are a similar color to the belly. Similarly to the brown trout, the tiger trout has a spotted pattern by its head. Female tiger trouts are a little more lackluster in color compared to the male tiger trouts. The females tend to be tan and light brown, with less orange and yellow tones. The trout weighs up to 3 lbs.


Tiger trouts are classified as piscivorous, meaning that they consume fish on a regular basis (particularly of the smaller variety). The regular diet of the tiger trout consists of a lot of larvae, insects and invertebrates. The territorial fish, which is notorious for its strong feeding patterns and appetite, also prefers streamers, nymphs and trout dries.


The tiger trout is relatively mysterious when it comes to temperament, although they are notorious for being able to fight aggressively and with a lot of strength. The fish is capable of swiftly traveling to the surface of water to eat. Since the fish does not reproduce, nutrients are unnecessary for reproductive matters and instead are used mostly for growing purposes.


Tiger trout do not exist naturally and only appear where they are produced. Some places with known populations of tiger trout include Utah, Indiana, Wyoming, West Virginia, Michigan, Colorado, Minnesota, Pennsylvania, Washington state, Ohio, New Jersey, South Dakota, Nevada, Montana, Illinois, Connecticut, Saskatchewan in Canada, New Zealand, Australia and the United Kingdom.


Tiger trout thrive in cold water environments, especially lakes. The hybrid fish does well in water that features sufficient aquatic vegetation, such as freshwater algae.
