Hi Fishraiders, mrsswordfisherman has asked me to clarify some of the issues you guys are discussing. Inevitably, this becomes a bit of complex discussion because ti involves animal welfare and best-use-of-resource issues aside from the strict rules and regulations, but at least you guys consider these things when you are fishing which is very refreshing! So, strictly speaking, the regulations with respect to releasing undersized fish or fish caught in excess of the bag or possession limits are:
1) If a fish is caught which is below the minimum legal length or in excess of the the bag or possession limit for that species, it must be returned to the water regardless of condition. Irrespective of the species, being caught is stressful for the fish and there are many complications which arise as a result of capture (bleeding resulting from deep or gill hooking, exhaustion, barotrauma, to name a few). It is, of course, up to the fisher whether or not they choose to attempt to help a fish recover from capture-related stress and therefore release the fish in better condition to improve its chances of survival. This is an excellent guide to best practices for successful catch and release of a heap of popular recreational fish species (http://www.dpi.nsw.gov.au/__data/assets/pdf_file/0005/605732/nsw-recreational-fishing-catch-and-release-handbook.pdf) - i think Paul may have already posted a link to this above. Sometimes however, despite the best efforts of the angler utilising all the best practices for that species outlined in the above document, the fish does not recover. If this occurs and the fish is undersize or in excess of the bag or possession limits, it must be returned to the water, even if severely impaired or even dead. This does not sit well with many people as essentially the fish is wasted, but unfortunately if this regulation was not back-or-white, there would be unscrupulous anglers who would take advantage of the loophole and intentionally keep undersized fish claiming that they could not be released. I doubt any of you guys would fall into this category
2) As far as fishing with underaged children goes (ie. less than 18), they are not required to have a licence, but still must adhere to size and bag/possession limits. So if you are fishing with two 10 year olds, the bag limit applies for each person fishing, not just the adult. The adult must be licenced however, even if not actually fishing. A full list of licence exemption circumstances can be found here (http://www.dpi.nsw.gov.au/fishing/recreational/recreational-fishing-fee/exemptions)
Hope this helps. Feel free to reply to this post or email me directly at julian.hughes@dpi.nsw.gov.au with any queries and i will try to clarify any confusion
cheers
