The decline in the sea-run trout fishery in Canterbury has little to do with angling pressure. Winter closure on its own will have little impact in bringing about an improvement in fish numbers.
How have we come to this state of affairs? The real cause of the fisheries decline is political. Too many consents being granted resulting in water being drawn from Canterbury’s rivers and aquifers to the point of un-sustainability. Added to that the ever increasing toll from pollution caused by sewage, storm water and agricultural run-off making our rivers unfit for swimming without becoming ill. When fishing the lower Waimakariri River anglers must be careful to avoid getting even a small amount of water in their mouths!
Environment Canterbury (ECan) was replaced by a commissioner, Dame Margaret Bazley, and other government-appointed commissioners, in 2010. You can read about it here in Rod Oram’s Sacked ECan Board was no Damp Squib. The reason the ECan Councillors were replaced is not hard to work out. It’s difficult to see real change happening there anytime soon!
The Once Mighty Lake Ellesmere Brown Trout Fishery
If we take a look at the shocking demise of the once incredibly productive Lake Ellesmere brown trout fishery you get an idea of how things can go badly wrong. The North Canterbury Acclimatisation Society (the predecessor of Fish & Game New Zealand) back in the 1940s, estimated the spawning population of the Selwyn River at around 65,000 trout. At that time the entire Lake Ellesmere brown trout fishery could possibly have numbered 100,000-200,000 adult fish – many of which were double figure trout. Back in its heyday prior to the 1950’s, Lake Ellesmere and its tributaries, most notably the Selwyn, were regarded as the best brown trout fishery in the dominion. The Lake Ellesmere fishery is still good, with some large browns being caught, it just isn’t a patch on what it once was.
Although there is no single cause for the dramatic decline man-made environmental factors have taken their toll.

Some Questions for Licence Holders Answered
Yesterday, (Tuesday 22 March 2016) I put the following questions to Rod Cullinane, General Manager of North Canterbury Fish & Game Council, concerning the urgent closure of the Eastern Zone below SH1, on 1 May 2016.
1. Is this closure now a certainty? No – the Conservation Act 1987 stipulates that the Director General of Doc needs to agree to it. An application to approve has been lodged.
2. Will those who have purchased a Full Season licence receive a partial refund – in particular, those who have purchased a whole season licence recently? Unfortunately no. S26ZL(1)(c) of the Conservation Act 1987 provides for the Director-General of Doc (at the request of Fish & Game s 26ZL(2)) to prohibit or restrict any waters or part thereof at any time. There is no requirement to make refunds.
3. How will licence holders be notified about the closure? By public notification in the newspaper and by email to all current licence holders.
4. What methods will be employed to monitor the health of the sea-run trout fishery going forward? Our Council has several ways it is considering doing this and will apportion resources both internally and externally to ensure that these waters are monitored so that this decision to close (or to re-open) the waterways concerned can be reviewed in the future.
We will keep you posted of further developments regarding the closure of the Winter Eastern Zone NCF&G 1 May 2016.
