Snapper spread thin across inner gulf as post-spawn season shifts tactics

5 min read

Decades on the water teach you that change is constant, but the past ten years have brought a shift unlike anything before. Adapting is no longer optional.

With spawning behind them, snapper push deep into the inner gulf, hunting baitfish and shellfish to restore condition and rebuild fat reserves. The traditional pattern holds to a point: fish move through the channels where current runs, then push further into the shallows of harbours and estuaries. What is different this year is the speed of that channel transit. Once clear of the channels, these fish spread across open sand and graze in ones and twos, much like brown cows scattered across a paddock. That is why so many anglers are reporting only a handful of marks on the sounder, where dense schools were showing just weeks earlier during spawning.

It helps to think about what your sounder is actually showing you. The coverage on the bottom is surprisingly narrow, comparable to a torch beam on a wall. Up close the spot of light is tight, and it only widens as you step back. In ten metres of water the sounder may be reading a strip of bottom less than a metre across, which is why a slow zig-zag approach into the current is the best way to build up a true picture of fish numbers across a given area.

The past three trips out produced scattered marks rather than any real volume, and anchoring strategy matters more than ever in those conditions. Setting burley and ground bait out from the stern lets it sink and spread over a wider area, drawing in fish that are well dispersed. Placing it close to the bottom concentrates the coverage far too much to be effective when fish are this spread out.

Patience is part of the equation now. It can take a good half hour for fish to work their way into the burley and start feeding confidently, so that waiting time is well spent collecting fresh bait. Pillies and squid will work, but it pays to consider what snapper are actually eating right now: shellfish, shrimp, and small baitfish. When bait comes back shredded, it is not always small fish to blame. That is simply how snapper feed in this mode, picking and tearing until the burley and ground bait draws in more competition, at which point they switch to aggressive, committed takes.

Fresh jack or slimy mackerel holds on the hook far better than a soft pilchard, and when fish do turn competitive they demolish it cleanly, producing a much better hook-up rate. Away from the channels, a quarter-ounce sinker is usually enough to get the bait down, but as the tide eases off it is worth removing the sinker entirely. A fish picking up a bare bait meets no resistance, and any movement in the line becomes easier to read. Cast well away from the boat and let the bait sink slowly back through the burley trail. Keep the rod tip low, stay alert to the slightest twitch or movement in the line, and when the moment comes, strike hard and fast while winding simultaneously to close out the slack and keep the hook buried.

A recent session showed how well this approach can work even when the sounder looks discouraging. Anchored in 12 metres over open flat sand with barely a mark showing, two baited rods were set with a coffee in mind and a quiet wait expected. It did not turn out that way. Both rods fired up and within 30 minutes a limit was on board, with the boat back at the house by 8.30.

The following weekend, the same ground looked even quieter, so the decision was made to push further out to around 22 metres. The sounder was no more encouraging there either, but anchoring up and sticking to the method was the right call. Two large unweighted baits went out: one directly astern and one off mid-ship to take advantage of the slight current and cover more ground as the bait drifted back behind the boat.

The first rod did not go off for about half an hour, and when it did, the excitement of the moment led to not winding down properly to account for line stretch and slack. The result was a missed fish. The same thing happened on the next bite, but the lesson was clear: let them feed, give a touch of slack, then wait with the rod tip pointing at the water until the line draws up tight before striking. With six adults and two hungry grandkids to feed that day, four snapper that would normally have been released were kept on board.

Conversations with bait fishermen over the past three weeks point to the same experience across the board. The general expectation is that as the water temperature drops a little, the bite should sharpen up.

Reports consistently describe fish running on the smaller side, mostly in the 29 to 35 centimetre range. The better fish are showing up at the change of light, tight to the rocks around Rakino and the Noises. The channel running between the South Island and Awash Rock is worth a look on an outgoing tide with a southwest to west wind. It has always been a reliable producer of quality fish, and at this time of year a line bait dropped there can also turn up some good-sized kingfish.

Closer to Auckland, slowly steaming into the current once in 12 metres from the Rangitoto light out towards A buoy has been fishing well on the incoming tide, particularly around dusk.

The summer weather has been inconsistent, but every chance to get out on the water with family and friends is worth taking.
