Trout, tiger
(Salmo trutta x Salvelinus fontinalis)
This is a cross between a female brown trout (Salmo trutta) and a male brook trout (Salvelinus fontinalis). It is primarily an artificial cross, though it has been known to occur in nature. Because of genetic differences between the two genera (the brook trout is actually a char), mortality of the eggs and alevin is high. About 65% of hatchery specimens do not survive and the loss is higher in the wild where the majority of normal eggs and alevin perish due to predation. Hybrid specimens that survive are unable to reproduce. They have primarily been produced only on a small scale in private hatcheries for stocking in European club waters and in a few limited areas on an experimental basis. Theoretically, they might occur anywhere that brook trout and brown trout inhabit the same waters.
The wavy tiger like markings on the sides of this hybrid give it a unique beauty. It does not substantially resemble either of the parent species or any other salmonid. The overall color of the tiger trout is brownish on the back, lightening on the sides and belly to a golden yellow with a brown or orange wash. The back and sides both above and below the lateral line display large prominent sunshine yellow vermiculations, or worm like markings, that are much more vivid and extensive than those of the brook trout. The dorsal fin is also brownish with yellow vermiculations. Large brown spots may be present on the adipose fin. The tail is dusky with brown or black markings and yellow visible beneath the dusky color. The rear margin of the tail has a thin black edge. The lower fins are brownish to orange with char like white leading edges. The anterior part of the belly may be white.
Overall, it is stockier and more aggressive than either parent and thus more easily caught. It is a surface feeder and is highly regarded by anglers in waters where it is stocked
