here's info i found dealing with safety:
Freezing Cooked Fish Leftovers: If you have cooked fish leftovers that are not going to be eaten within 2 or 3 days, you can freeze them for extended storage. Place the cooked fish in shallow covered container to allow the fish to freeze more quickly. Cooked fish can be stored in the freezer for up to one month.
It is always best to freeze and store frozen food in a freezer unit, rather than a refrigerator freezer. The freezer units will maintain a temperature of 0°F or below, which will allow food to be stored for longer periods of time. A refrigerator freezer will generally only maintain a temperature of 10°F to 25°F and is opened more often, which causes fluctuation in temperature. If fish is stored in a refrigerator freezer, it should be used within one to two months. The chart below shows storage times for fish when stored in a refrigerator or freezer.
Storage Times
(Suggested times for maximum quality)
Refrigerator (40°F) Freezer (0°F)
Fresh Oily Fish - Whole Fish Two to three days 1 1/2 to 2 months
Fresh Oily Fish - Steaks & Fillets Two to three days 1 to 1 1/2 months
Fresh Lean Fish - Whole Fish Two to three days 4 to 6 months
Fresh Lean Fish - Steaks & Fillets Two to three days 3 to 4 months
Store Packaged Frozen Fish Use within 24 hours of thawing 3 to 6 months
Cooked Fish Two to three days One month
Note: If storing longer than the storage times shown above, the quality may be affected
BUT, I think QUALITY would be 'not so good',, greasy food frozen tends to get even greasier and crisp food tends to loose it's crispness
Might just try doing a couple portions this go round, for a 'test' before ya do a BUNCH, unless someone with actual personal experience comes along
