Netting laws were a little different in my old neighbourhood,I often had 150 yards of netting right across the river,though not at the estuarine mouth but further upstream,never once prosecuted for it neither,so obviously legal,none of the anadromous fish I netted ever held owners-tags nor names and return-addresses,neither do I suspect they were bar-coded either,however should I have been committing an unlawful act then i was fully prepared to accept the consequences of my actions
