Tiger Trout (Salmo trutta X Salvelinus fontinalis)

, ,


The tiger trout (Salmo trutta X Salvelinus fontinalis) is a sterile, intergeneric hybrid of the brown trout (Salmo trutta) and the brook trout (Salvelinus fontinalis). The name derives from the pronounced vermiculations, evoking the stripes of a tiger. It is a rare phenomenon in the wild, with the brook trout having 84 chromosomes and the brown trout 80. Records show instances as far back as 1944. Because it’s sterile, the tiger trout is unable to reproduce and does not pose a threat of further hybridization with other trout species, however it is not often used in aquaponics systems because of this. They co-exist well with other fish species, and anglers are rapidly inquiring about how to add one of these gorgeous fish to their creel.
