It's just the way the 90% who cant catch fish bring the 10% who can down to there own level!!!
As far as at home goes i think your pretty safe unless you are blackmarket selling and fisheries get wind of it! The fillets in your freezer would have been portioned and maybe skinned, now unless they are going to DNA test to prove species and number ( there maybe just 5 VERY VERY BIG FISH) you'll be safe! Now as far as i know the dna tests are 18 month behind ( unless you rob the police ministers office ) so i cant see fisheries bothering with the time or expense can you!
