Fin-tastic Facts About The Splake For Kids

Splake facts about the hybrid fish.

Have you ever heard of a hybrid fish? No? Then you have landed at the right destination to take you through some fascinating Splake fish facts! Hybridization is particularly a hot topic for debate. Some argue it gives bonus points for sustaining and others counter it with the destruction of original species. One such species that could be a moderating bridge between the two arguments is the crossbreed of a Brook trout and Lake trout. The Splake, or as its scientifically called Salvelinus namaycush x Salvelinus fontinalis, possesses features from both its parents' Salvelinus namaycush (Lake trout) and Salvelinus fontinalis (Brook trout).

These Splake trout are found in freshwater habitats, and the trick for Splake identification during fishing is to keep a watch for their slight forky tail. This is their unique body feature. In fact, Splakes are extensively popular for ice fishing as well! What is significant about the Splake is that it is capable of creating quality fisheries where other hatchery species have not been successful, doesn't that count for a brownie point for any hybrid?
