No idea, but trying to find wild fish is becoming more and more difficult. Almost everything is farmed nowadays. 

Presumably so that they can fool people into thinking it has never been frozen and charge you more for it

Because people are stupid and will pay more for fish that 'looks' fresh that they can buy from a fish counter than they will for frozen fish in a freezer. 

If that wasn't the case, the supermarkets wouldn't do it. 

Stops them getting sued by over zealous lawyers whose clients break their teeth on it if not defrosted. 

I sort of get the point on a proper fish counter because it can be portioned/prepared as you request, but defrosting fish in packets is mental.

You don’t have to be a brain sturgeon to figure it out.

It's a load of old pollocks.

Actually, thinking about it I wonder if the fish is maybe frozen at sea on some giant deep sea trawler then defrosted to be prepped? 

It's a load of old pollocks.

there's a thyme and a plaice for that kind of language 

If anyone comes up with any better puns, please let minnow.

So that I can buy it on my way home from work and not have to wait for it to defrost before I can eat it.  I know that's a radical concept.

DD you may have a good point there tbh

Fish really doesnt freeze well. Cooked prawns ditto, and raw hooless if water added.

Sushi grade tuna must be frozen. 

Fish that is flash frozen on the boat immediately after being caught is ideal. 

Freezing fish in your home freezer is shit though. It freezes too slowly and ends up a bit rank when defrosted. 

If anyone comes up with any better puns, please let minnow.

Dux won't like losing out to other anglers - 'eel no doubt be turbot charged in his efforts to find more star fish puns.

Look all I said was this piece of halibut was good enough for Jehovah 

Stop carping Tesco has some good value packets of wild salmon and wild tuna in frozen.
