Statistically speaking, no significant difference. Fishing from a boat, regardless of gear type, often results in a quicker landing than fishing from shore. Steelhead resist being pulled toward shallow water along the shoreline, and they like to try to hide under boats, sometimes making for a real quick net job, well before the fish is played out. Nonetheless, mortality rates are about the same. Playing the fish a bit longer is irrelevant during the winter season because water temperatures are low, and lactic acid build up is not an issue. The primary factor affecting mortality is hook placement. Fish hooked in the corner of the jaw usually survive, even if handling is otherwise pretty bad. Fish hooked in the gills or eye are the most likely to die.
