Hey,
A while back a couple years ago there were a number of fisheries volunteers that would survey our catch when we would come back to the boat ramp after a days fishing in the hacking. They told me that they were undertaking the survey to establish how healthy the systems were and to get an understanding as to how good the general fishing experience was. The guy who was doing the survey at yowie boat ramp was a nice guy and he was there pretty much every weekend for a year.
Anyway i was always interested in what the results of the survey was, and i have come past the final report issued from the DPI for this survey.
Its a good read if you are interested in whats being caught in your local fishery...
