You can buy GS spawning mats. Pond fish require light (photoperiod) to spawn and hatch eggs. I would not put spawning sites/material under a dock. Might have better success buying GS fry by the box and releasing them into a protected area.

Don't know if you are feeding but well fed fish reproduce better and the fry grow quickly on feed.
