The disclosure is directed generally to an apparatus used to adjustably mount a fishing reel to the control end of a fishing rod. The fishing-reel-mounting apparatus is comprised of two main parts: (1) a rigid, light-weight, longitudinal track that is adapted to be securely and coupled to the standard reel-mounting region at the control end of a fishing rod, and (2) a sturdy, light-weight reel-carriage device that is adapted to be surely coupled at its top surface to the base of a fishing reel and is adapted to be slidably, adjustably, and lockably coupled at its lower surfaces to the longitudinal track. Among the key advantages of the fishing-reel-mounting apparatus is the ability for fishermen in the field to easily manipulate the balance of a fishing rod by allowing the adjustment of the longitudinal position of a fishing reel attached to a fishing rod.
