On the other hand...
Ages ago, I went houseboating with a heap of relos, including an auntie and uncle from overseas who had never fished before. My auntie kept bringing in yakkas, and she always got excited when she caught anything, so made alot of noise. The people in the neighbouring cruiser started yelling at us and said they were going to call fisheries on us.
We had no illegal catch on board, just a bunch of yakkas (one of my relos likes to eat them, I like to use them as bait).
If fisheries came and checked at the request of those wankers, they would have just wasted their time.
