A Truro man has been convicted for taking almost six times over the bag limit for Callop.
The Berri Magistrates Court imposed a $5,900 penalty, including fines and court costs for taking 39 Callop near Loxton in June 2018.
Minister for Primary Industries and Regional Development Tim Whetstone said the offender was detected and caught by PIRSA Fisheries Officers while on patrol.
"Most recreational fishers do the right thing. This conviction demonstrates if you choose to deliberately do the wrong thing and break the rules, you will be caught and face hefty fines," said Minister Whetstone.
"The bag limit for Callop is five per day. It is illegal for recreational fishers to take in excess of the daily bag limit, if caught you will face a fine of up to $20,000.
"It is up to all of us to ensure that our fishing stocks remain sustainable so if you see or know of anyone who is breaking the rules, please call the 24 hour Fishwatch number 1800 065 522 so that Fisheries Officers can investigate."
Reports of illegal fishing activity can also be made through the SA Recreational Fishing Guide smartphone app.
