Typically, fishing kayaks are too unstable and uncomfortable to be effectively motorized, and the maximum that anglers are willing to do with their kayak is to outfit it with a weak electric trolling motor, which is a solution for short term and short range, and not well suited for moving water.
Pedal driven kayaks present the same problems as kayaks propelled by a paddle, plus some more.
