Splake Brook Trout SQUARE TAIL FORKED TAIL While neither of these species are native, the creel limits differ and anglers fishing areas where both are present need to be able to distinguish them. Both brook trout and splake have light spots on a dark background. Some red or pink spots with blue halos concentrated on lower half of body. Lower fins and tail have striking white border offset by black. Angler can distin- guish brook trout by their almost square tail, whereas splake have a forked tail.
