The brook trout, the aurora trout, and the (extinct) silver trout all have physical characteristics and colorations that distinguish them, yet genetic analysis shows that they are one species, Salvelinus fontinalis. Lake trout (Salvelinus namaycush), like brook trout, belong to the char genus.
In the Little Delaware River the wild brown trout and brook trout populations are supplemented with the stocking of about 700 brown trout yearlings each year. The fish are stocked in a 0.8 miles (1.3 km) zone at the mouth and a 1.2 miles (1.9 km) zone downstream of the hamlet of Bovina Center.
The river itself and its many tributaries are home to many typical New England freshwater species.

The backcross is the result of an F1 splake male being crossed with a female lake trout (i.e., 75% lake trout and 25% brook trout).

In a 2001 study by the Pennsylvania Fish and Boat Commission, five fish species were observed at the mouth of Burgess Brook, including wild brook trout and brown trout. These included 41 individual brook trout, ranging from 50 to 199 millimeters (2.0 to 7.8 in) long, and one brown trout, between 150 and 174 millimeters (5.9 and 6.9 in) long.
