The best way I know to make fish soggy no matter how they are cooked, is to cover them tightly after cooking. The hot fish will cause foil/lids to condensate and the result is soggy crappie. The longer they sit under the cover, the soggier they get. This is why restauarants use heat lamps. If you need to keep flies, or bugs away, make yourself, or buy a cover made from screen wire and don't pile em too high.
