The year is racing by again as I sit to do this report and reflect on thelast few months it is a daze as I am not sure where the days go.We are planning a family trip to D’Urville for Easter and we are lookingforward to the break away from the hussle and bussle of our ever daylives, just to stop and reflect for a few days is what the order of theweekend is. Can’t waitWe have our new edition to the family coming with us too so that willbe Casper’s first trip to the island. Casper is a 5 month old Burmese catthat travels to work with us every day. His official title is PublicRelation Officer which works most of the time except when you have acustomer that is allergic to cats then he is locked away from the mainoffice.I have just completed my second every triathlon with amazing results (Ididn’t come last)A group of us did it and it was a lot of fun generally I just need to spendmore time on the bike; you never know we might even do somethingelse too. Might take the bike to D’Urville and get a ride to the top ofthe island.We have had some new people coming along to the club nights andjoining upThe Club dinner is on the radar for later this year so watch this spacefor the info for that and get ready to mark your calendar for a greatnight of entertainment, Brian has it all in hand so farJust remember that the AGM is coming up soon too so if any of you arekeen to come on the committee there is always room for new bloodand it will be very much appreciated if you did get in there a dosomething for YOUR club.That’s all from me this monthTight lines to you all From Your most Gorgeous presidentMaree Peter

Friday the 13th – by Jacob LucasTo some folk in Western civilisation, the day of Friday the 13th is consideredan unlucky one, triggering irrational behavior such as avoidance of black catsand ladder dodging, to name just a few. By no means would I deem myselfsuperstitious, but when given the option of Friday the 13th or Saturday 21stfor our wedding day, my wife and I choose the latter. Some believe the day isassociated with bad luck and misfortune (ask the poor English kid who gotstruck by lightning on Friday 13th at the time of 13:13), and I was ponderingthese very sentiments as I made my way up the Motueka River on a grey,blustery day. Usually, I wouldn’t bother fishing the Mot in these conditions,however the pressure to supply a fish for a BBQ that evening trumped normalcustom to stay at home, and my thoughts were elsewhere as Iabsentmindedly flicked a nymph into likely looking water that usually alwaysproduces a few fish. Today, just as I expected, the cupboards were bare. Itrudged onwards to the next run, convincing myself I was more walking theLabrador rather than catching dinner.Sometimes you have to be in the right frame of mind to fish, and in manycases I believe that concentration and positive thinking helps produce fish.As I gazed into the water, I was looking but not really focusing, and no doubtwalked past a few, until I stumbled onto a fish steadily feeding its wayupstream in the shallows. I counted myself lucky, this display of casualinattention would usually see trout melting into the depths, but this fish wason the move, energetically seeking nymphs, and fortuitously did not noticeme. I cast, saw the fish move towards my fly then the indicator shotupstream. It was a good solid hook-up and the fish rocketed out into themiddle of the river, jumped into the air several times before I managed to getit into the net. At 5 ¼ pounds, this was my biggest fish for the Mot thatseason. Images of smoked trout were put on the back burner as the fish wonits freedom to fight another day.With enthusiasm somewhat invigorated, I carried on and was rewarded withanother fish moments later after probing some likely looking water. The fishagain was a beauty, weighing in at over 4 pounds. Again it was carefully heldinto the water until it quietly slipped away into the shadows.Things were looking up, the wind persisted making spotting difficult. Periodicgusts created ripples on the water, but it was in between gusts that I spottedwhat looked like a very good fish stationed in a channel of deep, swift water,above a smooth piece of bedrock. Cont

Off went the weighted hare’s ear and on went a not– so– subtle monstrosity,commonly used on the Tongariro. I cast well above the fish, the disturbedsurface meaning I would not line it, ducking low as the bomb sailed forth,mere inches away from cranial collision.The fish seemed to show interest but declined the first offer. Again I cast,this time well above the fish and a metre to the right. It spotted the nymphand immediately moved towards it. I looked in dismay as a strong gust ofwind ruffled the surface and my indicator was dragged under with the weightof the nymph. I slowly stripped the line to remain in contact with the fly andwas delighted when I felt a solid resistance and struck. On setting the hookthe rod buckled and nothing moved. It was a Mexican standoff of sorts, and Iknew from experience this was a sign of a good fish as it wanted to play thelong game, never conceding any line. I was powerless, it made a fewattempts at dragging me towards the bedrock where it would look to breakme off, but after a while it surfaced and I caught a glimpse of the fish. It wastime to get serious. On several occasions I had the fish partially in the net,only to have it regain its freedom as I clumsily lifted, and thus the battleresumed. On my third attempt at sealing the deal I managed to coax thebeast into the net and was stunned at the size of it. The weigh net reveled abeautifully conditioned jack of 8 ½ pounds, easily my biggest fish from theMot after a good deal of effort over a number of years. I was astounded withits bulk, and was cursing myself for not bringing my camera, but I guessMurphy had to appear at some point.Elated with what had just occurred, I wandered upstream in a haze ofdisbelief. I peered into the next run and immediately spotted a dark shapebusily feeding on drifting nymphs. Again, it was a good fish, probably over 5pounds. This was a proverbial sitter and confidence was sky high as I shot theweighted hare and copper 5 feet above the fish, only to have it ignored.Nearly a dozen fly changes later, I was thinking of giving up on the fish, whenI spotted another fish a rod length upstream.Staying put, the cast was true and the fish obliged. Smaller in size, itimmediately sailed into the air and careered down past the lower fish. I didmy best to keep it away from the larger specimen and was pleased to see itcontinue on its feeding frenzy. A plucky hen fish – too small for the smoker –was landed and released.Sneaking past the still actively feeding fish, I headed to the eye of the pooland spotted another big shape, feeding well. Cont

A short cast was all that was required and the indicator was sucked into theripples. I realised this was, again, a good fish, due to the amount of heat Iwas putting into the rod for little return. The fish shot downstream andstraight past the other fish. I tried to keep a low profile – somewhat crab-like– as I hurriedly followed it down. Applying plenty of side strain, this fish wasnot to be easily persuaded. I eventually bought it in to submission 80 metresdownstream, and as it slipped over the rim of the net I again marveled at itssize. At over six pounds this was another uncharacteristic Motueka trout.My luck ran out when I made an attempt on the still feeding fish. Drained yetcontent from my efforts, a few more fly changes was all I could musterbefore I did something I don’t often do – I walked away from the still feedingfish, leaving it be, and deservingly so.It was a day when your average ‘run of the mill’ Motueka trout was not to beseen, replaced by fish which usually reside in deeper waters, mostly unseento anglers, and probably do their feeding at night. A day when the delusionof unlucky ‘Friday the Thirteenth’ was reversed, the superstition erased.Afterwards I was informed by my spouse that I had to, indeed, go to thesupermarket to purchase some steak for the BBQ. In her eyes I was a failure,but for me it was a day never to forget. Lake Argyle Tail race

Autumn fishing on the Tongariro RiverRecently I travelled north to visit a friend who, for 27 years,has been a victim of Multiple Sclerosis. This cruel disease hasleft him bedridden with little movement left in his limbs.Visiting him made me very grateful for my health and myability to carry on fishing.I took advantage of being in the North Island to add a fewdays to my trip and go fishing on the Tongariro, arriving atTurangi to stay at TALTAC, a very comfortable angling clublodge. Initially I planned to fish the Tongariro on day 1, theWanganui on day 2 and see what happened from there. Basedon last years’ experience of poor fish size and slow fishing Ihad low expectations of the Tongariro.After a visit to Sporting life, the local tackle shop, to stock upon flies, leader material, and advice, I started on the HydroPool, fishing a caddis imitation with a size 16 flashbacknymph below. On my second cast of the trip I caught my firstfish, a nice feisty rainbow of 2.5lbs or so which I released.Continuing upstream, fishing the shallow (knee deep) andpocket water in the faster water above the Hydro Pool, therewere several fish seen feeding, but my lack of skill let medown and I failed to catch them. Having crossed the riverabove the Never Fail pool I saw several fish feeding in thechute above, but as a guide and his client were already there Icarried on further upstream to the Kamahi Pool. At the baseof this pool trout were rising, some large fish 4lb+ clearing thewater, a sight to gladden any angler’s heart. I caught severalfish on the nymph, all about 5lb, like rugby balls, silver freshrun fish in superb condition.

All in all a great day fishing on the river, with 5 good feistyfresh run fish landed, and a few more hooked and lost.This fishing was so good that instead of going to theWanganui River the next day, I walked downstream to fishthe Judges Pool. (A favourite of Lester’s, such that some werecalling Lester the judge). Unfortunately there was no actionthere, but upstream in the braid of knee deep fast water thedry fly and nymph did its magic with two fish hooked andlanded and one hooked and lost. All this action happened in avery small 30metre section of river.The next fishing spot downstream was a remnant pool fed bya moderate braid where trout were freely rising to insects onthe surface. My initial try with the caddis fly was refused, aswas the passion vine hopper, but the nymph did its job,

allowing two very nice fish to be caught and released. At onestage a mallard duck tried to take the caddis imitation, and Ihad to flick the fly away. It’s the first time I have a duck showinterest in my dry fly.Back downstream, fishing the bridgepool below the main road, I changed to the conventionalTongariro nymph rig of a canary indicator, and two weighted

flies, in this case a “bomb” size 8 weighed price nymph, and aflashback pheasant tail nymph. Here I caught three andlanded three and failed to land another, lost at the bank. Alltook the small nymphNot all my fishing was a bed of roses as I managed to catchmyself, and set my heavy weighed nymph into my neck.Getting the hook out was not much fun, a good argument forbarbless hooks, but there is no excuse for my poor castingskill.The next two days was spent in the company of a familymember who wanted to learn how to fly fish. I spent anenjoyable two days showing him how to cast and trying toteach him the ways of the river and the fish. We caught veryfew fish and those we did we failed to land, but he seemed toenjoy the challenge and just being out on the river.To finish on a high note a final evening fish in the Bridge Poollanded three nice fish in less than an hour.For me, this was magic fishing. I was, by luck, fishing at atime when recent rains had caused a run of fish in the river.These fish were in superb condition and 4-5lb which augerswell for the coming season.Jean

A Photographer goes fishing by Pam FrahmFilling Dennis Ealam’s shoes is not an easy task. Last year I agreed tobe Fred’s off-sider for the March fishing challenge, i.e. to fill enoughAgee jars to have salmon for lunch for the next year. But, before Icould even depart with the boat, Fred and the caravan were evacuatedin the Great Flood of 2016, when the Waiho River broke its banks. Theonly thing entertaining that trip was seeing him on the 6:00 newsbeing interviewed by Channel One as a brave survivor.So, here I am, loaded with Merino and wet-weather gear from theKatmandu 50% Off Sale. While Fred checked his lures and lines, I filledboxes with things to do, expecting days of cold rain, holed-up in ourlittle house on wheels.Planning to “leave tomorrow morning”, our first delay was the campernot passing the WOF. Nothing easy, it was electrical, and after manylearned men couldn’t find a fault, they just re-wired it. Then wedelayed a few more days waiting for another messy front to passthrough Glacier Country – it’s no fun setting up in the rain, on soggygrass.Then, since I’m more a precious orchid than a hearty weed, I insistedon a 2-day drive, stopping in Greymouth for one night. Long-story-short, we set up, in the sun, at the Top 10 Holiday Park at Franz Josef.We chose site 113 (and 114 and 115) with 2 cars, a boat, a caravanwith the canvas Annex, and extra picnic table for the satellite dish…directly across from the toilets and kitchen. The management was finewith our arrangement, since every sensible tourist had left the district.We didn’t fish for the next 3 days because of another big front, but wedid venture to the Otto/MacDonald’s DoC camp to let all the annualregulars know we had arrived. Many had already left, with nothingcaught, but we chatted about Dennis and years past, and hoped this

present downpour would do the trick: raise the lake level and send aflush of water down the river to the sea.The DoC camp is still non-powered, but has a new covered area withtables and sinks, and there are even 3 flush toilets at the picnicgrounds. But the fees have also gone up, so for a few dollars more Iwas happy with the extra luxuries down the road: TV room with Sky,Spa, Laundry, free Wifi… and long, hot showers.When conditions were finally perfect we launched out… at 10am.Sand fly stuff, sun burn stuff, packed lunches, dry-bag with a variety ofclothes, umbrellas, hats, magazines, and my green garden deck-chair. Ihad never been in the yellow Smart Wave before, and would alsochristen all my new clothes, my new rod, and exercise my first everFishing License.Trolling is the name of this game… and on this magnificent lake, youdon’t go far. The fish arrive from the sea in one river, take a breatherin the lake, and then go up another river to spawn, the mouth of whichis only 100m away. So, like a crescent moon merry-go-round, theboats go up and back all day shouting to each other, “nothing yet”.This year the problem was, that both the Okarito and MacDonaldrivers were so low they had gone underground, and the fish out at sea,and in the Lagoon, were waiting for rain, while we were waiting forsun. Even after our mini Weather Bomb, it would take 2 days for thelake to rise enough to fill the Okarito River, and then 2-3 days for thesea-run salmon to maneuver the 12k to Lake Mapourika.So, prepared to be quite bored, once our lines were out (I used aWarden M2 Flat Fish lure which was blue with orange dots), and ourroutine was set in motion, I began to read, out-loud, 8 issues of theTasman District Council’s newsletter. Cont

It was 1:15 when I heard my reel start to m:ake noise. Not reallyknowing what to do, I tried to hand the rod to Fred, but he insisted I“bring it home”… he would man the net. It jumped twice inspectacular fashion and after reeling in the 50m of lead line, it was inthe net. Having only seen fish at Guyton’s, it was ENORMOUS, and hadto be bent to fit in “Fred’s Coffin Box”. On shore, someone had a scaleand it weighed in at 7.2lbs.I would catch one more that week weighing in at 9.6. And, that waswith his tail cut off, because he was way too big for the box. Scrapswere eaten for breakfast, cocktails, and dinner, while most of the meatwas bottled in Dennis’ old pressure cooker.I suppose my “beginners luck” is all used up, but I think I’m hooked –fishing is fun. And maybe next year I’ll even wake up earlier, and fishin the rain. Cont.Lake 1 Lake 2

Report from the bimonthly meeting of the Nelson Marlborough Fish andGame Council meeting held 11th April 2017 in BlenheimThe meeting agenda included a review of the Council’s governance rules,financial statements, accounts for payments , adoption of the annualoperational work plan, and setting the meeting date for the fish sub-committee.The “Fish” sub- committee will meet in Havelock on the 23rd May. (This iswhere the recommendations for local regulations, bag limits and river statusare determined. The recommendations of the Fish committee are approvedby a full council meeting, before being presented for the Minister to approvefor the next season’s gazetted regulations)If wish to have a say on bag limits, permitted fishing methods, or any part ofthe local fishing regulations this is the venue. Put your views in an email orletter, or talk to your elected councillor. The meeting is open to the public. ******************The council was advised that the “Guide’s License” still is waiting for theMinisters signature before it can take effect. This Guide’s license is a sagathat goes back many years and many people have been involved in trying tobring it into being. We have now achieved agreement with the affectedparties and only require the Minister’s signature. It is disappointing andfrustrating that this has not happened. The council passed a motionexpressing its concern about this delay. ******************Reports were received by the Council of fishing guides monopolising rivers,claiming that they had been allocated a beat of the river, and that all otheranglers were excluded. The reports concerned the Branch River, and theguide(s) had a European accent.The council was outraged by this and directed its manager to respond. Part ofthe response will be a reminder to all anglers, and especially guides andfishing lodges, of the ethics of angling in the region ******************A paper presented to council generated intense debate about fishinglicenses. Topics includ4ed participation, type, cost duration, non-residentlicences , and the impact on our fisheries. : ContOf concern was a graph showing the number of fishing licenses sold as aproportion of the population. If the trend in this graph, which dates backto1987, continues there will be no anglers in the future. The message fromthis information is that we have to be more inclusive, and seen as not just a

white Anglo-Saxon male group. We need to be more inclusive, get intoschools. Ideas include getting information into schools, contact with ethnicgroups.Changes we recommended include:-  Imposing a limit on the number of consecutive days that a day licence can be issued for, with the proposed limit being three days, and then not reusable for a further five working days.  Broadening the use of designated fisheries as a useful management tool in the promotion of more whole season(including non-residents) licences.Jean Willis.

Drift of invertebrate larvae in theTONGARIRO RIVERBy Dr. Ivan TomkaThe current in a running water body may carry invertebrate larvaebelow the surface. This phenomenon is called in aquatic biology, thedrift. Needham discovered the drift in 1924 as a widely occurringphenomenon and it has since been confirmed in many rivers around theworld. We are still unsure why the larvae release their hold of thesubstrate in the benthos. One frequently mentioned reasoning impliesthey require new feeding sites. However, it is well established that thedrift is a collective phenomenon covering the whole mobile benthicfauna; only the net building Trichoptera don't leave their habitat and arenot participating in the drift. It is also obvious there must be sometrigger for the drift. What we do know is that rivers inhabited by troutshow a distinct daily distribution of the drift: it follows a timelydistribution showing high drift concentration at given hours.Researchers have also found rivers in New Zealand which are notinhabited by trout but otherwise similar to those which are, showing nosuch timely peaks of the drift. They concluded that trout as typical driftfeeders may terrorize the benthic fauna elements, which themselves tryto avoid this pressure by escaping in high numbers. The feeding time of the trout is strongly related to the peaks of thedrift; also that of another salmonid drift feeder, the grayling. The authorremembers well the good fishing times in Switzerland before egoisticdiary farmers ruined almost every river there. One could catch trout upto 12 pound and grayling up to 5 pound in the middle of the capital,Bern. In winter when the fingers were freezing, at 9 and 11 o'clockthere was a drift peak and consequently feeding time for the biggrayling. Once somebody landed a huge grayling at 10 o'clock, creatinga tremendous discussion whether this was a late 9 or an early 11 o'clocktake. New Zealanders by the way, could learn from the mistakes ofthose money-oriented Swiss farmers but obviously they are even morestubborn. :Cont

The extremely rich fauna of the Tongariro River allowed theutilization of a drift net with a rather small cross-section. The usual sizeof the net is several square metres and will be spanned across the riverby ropes. We used a bag-shaped, at one end closed net which was fixed to aframe of 0.07sqm. Two steel slabs of 2cm thickness were driven intothe bottom of the river at the sampling site. The frame was fixed to theslabs using 4 short tube sections welded to the frame of the net. Thisway the net could be adjusted at the proper depth of water. The lowerend of the frame was 20 cm above the bottom of the river, the upperpart was 5 cm below the water surface. The net was emptied every hourand the catch counted.THE SAMPLE SIZE AND CORRESPONDING SAMPLETIMING5.30-6.30 o’clock: 7 (captured fauna elements),6.30-7.30: 97.30-8.30: 88.30-9.30: 259.30-10.30: 1510.30-11.30: 711.30-12.30: 2612.30-13.30: 1513.30-14.30: 1014.30-15.30: 2315.30-16.30: 1716.30-17.30: 1317.30-18.30: 1018.30-19.30: 1319.30-20.30: 1120.30-21.30: 1221.30-22.30: 11922.30-23.30: 70

An accidental drift can happen at any time to larvae living in runningwater but above this we observe at given time-intervals a more frequentdrift rate. There seem to be 3 smaller drift accumulations between 9 and10, 12 and 13 and 15 to 16 o'clock.A much more pronounced drift peak occurred between 22 and 23o'clock. Sampling in Europe – in May, which correlates to ourTongariro sample made in November – we observed a similar driftdistribution.: ContDuring the drift sampling several fishermen were active in thesurroundings, taking very much care not to go into the water above thesampling site. The observed catch rate correlated well with the driftpeaks. The hatching insects and their larval shucks were also collectedin the drift net.The drift samples contained all the fauna elements found in the kicksamples. It astonishes the author every time dealing with the drift thatthere are accumulations in the drift. It means that the benthic fauna ofthe river reacts concertedly in this respect.



AQUATIC INVERTEBRATES COLLECTED BY \"KICK-SAMPLING\"THE TONGARIRO RIVER, 11/11/2016A tubular, on one end closed 1 m long net was fixed over a 50x40 cm frame tocollect invertebrates from the benthos of the Tongariro River. Two collectingsites were investigated each 1 sqm: 1. 200 m below Red Hut Bridge and 2. 1500m below the SH1 Bridge. The composition of the samples was similar and thetwo samples were pooled. The sampling sites were covered with pebbles of 1-10cm size and boulders of 10 to 30 cm diameter. The speed of the current wasguessed to 30 metres per second and the depth of the water was 50 centimetres.Plecopera (stoneflies): 3Austroperlidae - Austroperla cyrene (Newman): 1nonidentifiable plecoptera: 2Ephemeroptera (mayflies): 270.OligoneuridaeColoburiscus humeralis (Walker): 123last instar*: 41instar 7 - 10: 20instar 4 - 6: 33 Common pattern: Kakahi Queen Nymphinstar 2 - 3: 29Leptophlebiidae: 142Deleatidium lillii - group: 126last instar: 21instar 7 - 10: 38instar 4 -6: 41instar 2 - 3: 26Zephlebia inconspicua (Towns): 2Mauiulus luma (Towns and Peters): 1 :Cont
