IMO fishing and kayaking don't go together. At least in the type of kayaks we used. Limited space for fishing gear to begin with and tough to land any fish on a closed deck with spray skirt.

Your Kruger style boat would work better for fishing.

Not any weed beds that I saw, looked pretty sterile to me. I would think you'd have to focus on the river mouths.

Wait a couple weeks for the finish. ~ early Nov.
