After all, angling is all about understanding how the fish operates. By ensuring your bait, line, method, and tackle suitable for the fish you’re about to catch, you save yourself plenty of time and effort.

Brook Trout have recently seen a decline in their populations due to loss of habitat and other factors.

But what makes the Brook Trout different? How can you distinguish it from a tiger Trout? Let’s see.

The Brook Trout, similar to its hybrid offspring, is covered in vermiculation. Vermiculation is the dark irregular pattern that you can see all over its body. Its colour ranges from greenish brown to lighter shades, with the vermiculation appearing in lighter colours all over the body.

The colour of the belly ranges from light yellow to orange, depending on the season as the adult males get reddish-orange bellies during spawning season.

Its size is in the range of 10-25 inches. Some Brook Trout weigh as low as under 1 lb, whereas some weigh as much as 6 lb. Their tail fin is similar in shape to the Tiger Trout’s, as it is also square-shaped.

However, a few things can help you differentiate the Brook Trout from the Tiger Trout. The Brook Trout has a scattering along its flanks of red dots surrounded by a blue shade. The Tiger Trout does not have that.
