Ducks, Geese, Deer and Trout

Whether you are an angler targeting spawning trout, a hunter stalking rutting deer species or a shooter waiting for incoming mallards, there is excitement aplenty in autumn, writes Greg Morton.

Autumn is my favourite season of the year because it is the time when all game is active. Recently I fished the Pomahaka River in West Otago and though I was two weeks shy of the duck shooting season, could not believe the number of mallards, paradise ducks and Canada geese I observed. The mallard ducks in particular were black on the water, and the geese and parries I flushed off a riverside pasture numbered in the hundreds. The air was full of beating wings, quacks, squawks and honks. It looks like lockdown last year and a good breeding season has meant a duck and goose explosion.

According to monitoring completed by Fish and Game, mallard numbers are up 10 percent. “Parts of the Clutha and Pomahaka rivers had some of the highest recorded concentrations of ducks since 2015,” said Otago Fish and Game officer Bruce Quirey. He also said that one river section had almost doubled its previous highest count.

Based on his comments, I think the area he was talking about was where I was fishing. The daily bag limit for ducks in Otago is 25 a day.

Deer are another attraction close to here: both red and fallow. The evening before my fishing trip I had hunted for a fallow buck on a nearby farm and though he had proved elusive, I got the drop on a black fallow doe and her young offspring. It’s not often I get to practice ‘catch and release’ with my rifle but because of her smallish youngster, I photographed them instead of harvesting mum.

West Otago is a hunting, shooting and angling paradise, with small community towns, a low human population and well regarded rivers and forests. State Highway 90 runs north-south through a large valley system linking SH 1 near Gore and SH 8 at Raes Junction. The dominating Blue Mountain range (nicknamed the Blueys) near Tapanui is recognised as the historical home to quality black coloured fallow deer.

Once the cloud of ducks and geese above my head had dissipated, I focussed back on the fishing. The Pommy was very low and sluggish but the odd rise meant some fish had survived the big floods back in January. Tree debris littered the banks, but the streambed was clean.

The Pomahaka River’s water colour is dark so you seldom see trout until they hit your offering or when they follow a lure into the shallows. Being late April, I was hoping I might encounter a big Clutha River sea run trout on his spawning run. I fish this river with a white, brown or black spinner as they provide a good silhouette. The first few casts with the white spinner were underwhelming but as I worked my way along a fishy looking stretch, I began to see trout showing interest in its presence. A few followed it in, a couple nipped it and one small fish was momentarily hooked before spitting it out.

Half an hour later I got a good strike but it too escaped so it was time for a change. I removed the white spinner and tied on a brown one of the same Mepps style. Three casts later it was whacked and this fish was a fighter. It ripped off line with ease and then began jumping. At this point his identity was revealed and surprisingly, it was a 1.5kg rainbow jack in early spawning colours. Being well hooked, his efforts to escape were in vain and I eventually landed him. I unhooked him and slid him back into the water.

Success had taken a while but sometimes all that is needed on the day is a colour change. Soon after I came across a pool that just cried, “Trout living here”. It was on a bend, where shallow water hit a submerged tree then became deep, slow flowing water. My first cast was hit instantly and though slightly bigger than the rainbow, this fat brown trout was much easier to land. He too was released quickly.

A change in lure colour quickly produced fish for the writer.

The river had taken a real pounding from the earlier floods and the trout too would have suffered. One dark brown trout I came across nestled against the bank was either a victim of spawning or the angry river. He carried many scars and I think he’d be lucky to make it through winter.

I carried on upstream and came across a new pool created by the floods. Previously the best lie here was impossible to access but now the glide was on my side and casting out was easy. Just like fly fishing, your first cast is often your best chance of success and sure enough, a feisty 1kg brown grabbed it and quickly came to the net. My next cast also attracted action and three times on the retrieve something disrupted its swimming action. There was no hook-up though and as it came into sight, I could see a very big brown trout shadowing it. It saw me as well and sank into the depths, not to be seen again. Its size hinted at sea-runner parentage.

The eye of the same pool was deeper, so to get my lure down I tried a new trick. About 40 centimetres up from my spinner, I added a three-way small swivel and from the bottom eye attached a small weight. I thought it would tangle in flight but instead it worked as intended and was grabbed by my second rainbow of the day. He was a twin of the earlier one and like him was released. West Otago had produced the goods again.
