Scoot,

Not sure if this is answering your question, but here goes.

The best, quickest, and safest way to thaw out your fish
quickly is to place the fish in a plastic bag, then place it
in a tub of water with a faucet just barely running into the tub.

The just barely running water will circulate water around the
frozen fish while safely thawing it.

FYI: This method prevent bacteria back up on the surface of you thawing fish (or any proteins).
Leaving meat or fish on the counter to thaw is a dangerous practice.
