It's very interesting, but take a notepad and pen. Yes it's only 2 days but covers a lot of stuff and some of it can be a bit intense. 2 days isn't enough really and if it's something you're interested in doing I suggest a proper course on fishery management not just a 'taster'. There should be courses in your area.
If you are interested in learning a bit more about fish and fisheries management after the weekend then the IFM offers a course that may be of interest. The Certificate in Fisheries Management is a one year correspondence course that you can study in your own time and at your own pace. There are seven units to choose from and it is assessed by open book exams that you can take at home. All of the details can be found on the IFM website IFM Certificate Course - IFM
