Assuming you have a dock that is made of concrete, out GBS Penetrating Concrete Sealer will seal it well provided it is clean, dry and has not been previously sealed or painted. It will not change the surface or make it slippery as it is a penetrating, not a topical sealer. It has not been tested on fish but once it has cured inside the concrete, there will be no exposure.
