When an uplift pushes a batholith or smaller body of hardened magma toward the surface. And sometimes when magma fails to reach the surface it hardens in to rock. Over time, the forces that wear away Earth's surface such as flowing water, ice, or wind-may strip away the layers above the hardened magma and finally expose it.
Deciding if a trout is a sea trout or a brown trout can be easy if the sea trout is fresh run from the sea âsea trout are distinctively silvery in colour and may still carry sea lice. However, once they have been in fresh water for a while they return to brown trout colours.
Any brook trout taken today along the south shore are stocked fish which do not reproduce. Preferring clear, cool water of around 40-55 degrees, it is near impossible to have stocked fish holdover from year to year since few of the bodies of water here on the south shore can keep that environment throughout the year.
