Funny thing is, many pro fishermen's attitude to rec fishermen is exactly the same as some of the most extreme greens: they'd be all too happy if rec fishing were banned or at least severely restricted in Moreton Bay.
Politics does make strange bedfellows though, just have to be real careful who you climb into bed with (to continue the metaphor; you don't want to be having to gnaw the old arm off in the morning rather than wake your sleeping partner ;-).)
