Merimbula Fisheries bust: Victorian man caught with 106 bream

All of the fish were in breeding condition and the man is expected to be prosecuted for the offence, which carries a maximum penalty of $44,000.

NSW DPI Fisheries director of fisheries compliance Patrick Tully said the SOIG teams are working with local fisheries officers using a wide variety of sophisticated investigation techniques and those flouting the rules should be concerned.

"We have had some great results across NSW on the North Coast, Illawarra, Hunter and South Coast. We have a range of surveillance technologies available to us and we're employing them across the state," Mr Tully said.

"The vast majority of fishers do the right thing but unfortunately there is a small minority that does the illegal fishing and those responsible need to think about whether they're being watched by our fisheries officers."
