Sonar tagging Zambezi Sharks with Calum Murie

Although Zambezi Sharks are on the top of our hit list, these blacktips are also featured.

Sonar tagging Zambezi Sharks: Calum Murie could have been anything. But he chose to spend his life chasing huge sharks around with sonar tag in hand, ready to abuse the first full grown Zambezi Shark he sees. In the name of science, research and conservation, Calum’s motivation for this career path runs deep and his commitment is exemplary.

And so it was that Calum enlisted the crew and facilities at the BCSS (Bazaruto for Scientific Studies) this September, to get some more tags installed in some Zambezi Sharks and other suspects. The tags are monitored by sonar listening stations set out up and down the coast between Pemba and Cape Town. So if one of Calum’s tagged sharks goes on leave and heads off for a holiday, Calum is gonna know about it.

This behavioural study of horizontal movement is aimed at supplying decision makers with the correct information regards shark activity along our coastline. Sadly, there have been over ten shark attacks in the Inhambane Estuary just down the coast from the BCSS. It’s the poor crab ladies who are getting taken the most. They are sitting ducks working in a metre of cloudy water at best.

And so Calum is fiercely chasing Zambezi’s, the prime suspect as usual. Although bronze whalers are also on our shark tagging list for being a suspicious character. Calum is also after Tiger Sharks, but we have not been successful at this as of yet. Hopefully we can find a small one somewhere!

You can actually get involved in our shark tagging exploits if you like. The success of the project that Calum is running, has opened up more funding for his studies. More listening stations are being deployed in association with the BCSS and Dr. Mario Lebrato. And we now have another batch of tags to deploy. At over $1000 per tag, we have got responsibilities!

The BCSS was built in order to facilitate research and conservation. So if you are aligned with these objectives, get in touch to join the team for a week or two. Rates are very reasonable. And you get to stay with us out here on the edge of the whole world!

More predator fish attack behaviour with the BCSS

Dorado Weather! A Bull Dorado comes storming up the white water behind and slammed this little rubber lure. Letting go at the last minute.

More predator fish attack behaviour with the BCSS

Fish behaviour studies at the Bazaruto Centre for Scientific Studies: The accompanying video features four species of fish and their different reactions to some of our trolled baits up here in Vilankulos waters.

Some days the water got real blue lately, but many other days have been plagued by a bit of green in the water. However, we have worked out distances from camera to fish nicely – the last clip in the sequence shows a huge blackfin shark come screaming on our marlin bait, chomping the wax thread that help the tuna to the circle hook, as they do.

The first clip, is that of a real nice sized bull dorado having a go at a paddle tail. Spectacular as the fish uses it’s prolific sail in the attack sequence. One of our best shots ever (thanks to Dr. Mario Lebrato for going to all the effort to get these clips).

Then a real interesting one comes on, revealing a noisy, ugly white hard plastic noisy lure, that just outright fails to convince the spritely little Cobia that came up from out of the depths to have a look. A very close look. Centimetres behind the clanging lure. And then, unbelievably, he gives it a nudge. When it doesn’t react like a real fish, the Cobia tries again until he convinces himself that it’s not worth it. And peels away unimpressed.

Then we were going slow for some reason, and a whole shoal of cute little yellowfin tuna come into the scene. The camera was upside down at this slow speed so the video can look a little confusing.

Enjoy the fish behaviour action…

The BCSS, on Benguerra Island, has been real busy hosting a group of whale behaviour scientists right now. More about that to follow…

BUT, Captain Duarte Rato officially started his season this week, and he will certainly be doing his homework and tagging and posting for us. His latest report can be seen here -> http://fishbazaruto.com/2018/09/18/early-september-18-fishing-update/, and is a real good one again featuring shoals of yellowfin, some wahoo, and two sailfish. All in days work for Duarte and crew once again on the good boat Vamizi. Who I saw moored at Vilankulos the other day – looking beyond spectacular in preparation for the season.

Now if only this East wind would stop!

The day the “mojo” worked: The Sailfish Interprovincial by Captain Len Mathews

Another beautiful Sailfish lives to tell the tale

The day the “mojo” worked: The Sailfish Interprovincial by Captain Len Mathews

Mydo team rider Captain Len Mathews checks in with a fantastic roundup of his teams recent success at the 2018 Sailfish Interprovincial held at Sodwana recently. It is an extremely technical and thorough reference as to what it takes to consistently catch more fish than the competition.

Congratulations Len, and thank you for the informative and totally interesting article!

Keep winning!


Hi Sean,

Been a while since I last spoke to you or contributed to The Sardine News. You asked me for a story and pics on the Sailfish Interprovincial we won recently, so here it is:

The day the “mojo” worked:

The Sailfish Interprovincial Is a yearly event held at Sodwana, in winter. The “who’s who” of sailfish angling represent our country’s Provinces in this event. This year 11 Provincial teams, consisting of salted provincial, SADSAA and Protea anglers participated in this 5 day competition.

I am sharing what our Griquas green team did to pull this off. It is in no way whatsoever a seminar on sailfish angling, a “what to do” article or any intent for this article to be of any educational value. This what we did to catch 5 sails in 2 days. Considering the other 10 boats caught 4 between them, I consider this not to have been a “luck shot” (no pun intended).  (ha ha thanks Len – Sean)

My team consisted of myself, my wife and fishing partner Alta and my good mate and longtime fishing buddy Donald Finlay, We fished off Jannie Nel’s “My Lady”, skippered by seasoned Sodwana skipper Follie van Vuuren. Between myself (40 years), Follie (15 years), Donald (30 years) and Alta (5 years), we have 90 years of combined experience fishing Sodwana. This also proved to be of great value, especially in this Competition!!

I am dividing this story into subsections, to form a clearer picture of the “process” we followed with preperation and execution of our plans.

Bait:

We all know proper bait is the answer to most questions. THE bait for sailfish is obviously halfbeaks, the fresher the better. On a good day a well presented stripbait also does magic, but in my book it is nothing more than a good second prize. I am lucky enough to have access to prime halfbeaks, so this is what I stick to!!

Bait preparation:

I was introduced to a good brine that my good mate and Protea angler, Paul Borcherds brought in from the USA. I had it analysed by a lab and now probuce a 100% copy of it. I brine all my baits for 12 hrs before rigging it. The advantages of the brine is tougher baits with much more enhanced colour. After brining baits, I have used the same bait for 4 days in a row, without it showing signs of excessive deterioration.

Bait rigging:

I rig sailfish baits in 3 different ways, depending on the position you want to swim it in. I rig them headless, whole double hook rig or chin weight rigged for circle hooks.

What goes where?:

I normally (take note I say normally, not always) swim smaller (head off) baits on my long riggers, 10-15 m behind my short riggers. On the short riggers I normally (….) swim larger (whole) baits, not more than 5m behind my teasers. This can either be a whole halfbeak with lure over it or a chinweight rigged halfbeak on a circle hook. On shotgun I will use any one of the two double hook rigs, mostly with a small bird in front of that. My teasers I will usually swim 20-25 m behind the boat, from the middle of the outriggers, in clear water next to the white water. In “normal” angling conditions this causes just enough commotion close to the boat, to get attention and lure the fish to the boat. This covers 5 baits. My 6th bait will be a lipped lure below and between the teasers or a normal bait behind a cupped lure running in the “dead triangle” between the long riggers and shotgun, in line with the long riggers. I use a dark lure to contrast in the little foam or white water there is. This is my “basic” spread, that works well 80% of the time.

Conditions:

Weather was not too good for the whole of the Sailfish interprovincial 2018. The first two days of the comp was blowouts, leaving only 3 days to fish. There was an abnormally high barometer at the time, for the whole duration of the comp. That proved to be the major decider in the end!!

Day 3 (1):

The day “normal” left the bus!!

I firmly believe that on this day, the comp was “handed” to us. 2 Fish were caught by rival teams. Reports of fish coming into spreads, appearing to be shy and skittish to attack baits and eating baits furthest away from the boat, made us fall back on experience. We als had fish pop up further from the boat than usual and showing a general skittishness to eat. It took us half a day to figure this out, but we immediately knew that the “culprit” here was the high barometer. We also realised that this was a situation of “to achieve something different, you have to do something different”. We had a good idea what to do the remainder of the competition.

Day 4 (2):

Mojo day!!

We changed our game totally!! Firstly we did not put a single teaser in the water.We believed that too much commotion close to the boat scared the fish, especially as a result of the high barometer. Secondly we only used dark or lumo lures in front of our baits and only one circle hook bait in the water. Thirdly, we also used very small baits, as the sailys were mostly small fish. Lastly, we dropped ALL the baits at least 15-20m further back than what we normally do and we slowed down our trolling speed to just enough to make the baits break water every 4-5 seconds….. Just before 08:00 we had a tripple strike. One did not stick for long and came off quickly, but 2 were vas!! 20-25 mins later, myself and Donald each released our fish and jubilation was the order of the day. At this stage we KNEW we had diled in on the mojo and this was our comp to lose. We also noticed that it appeared as if none of the other teams changed their modus operandi to suit the conditions.

After brief congrats, we put out an identical spread. We knew it would only be a matter of time………which it was. 11:50 we had another triple strike, one on the circle, long rigger and one on shotgun. I took the circle, set the hook properly and Alta took the other.The third rod was on, but also came loose quickly. Another 20-25 min later, we both released our fish. To say that a small party broke out on “my Lady” is an understatement!! We knew that for anyone to catch us now, they had to release 5 fish, a tall task is conditions like this!!

Day 5 (3):

After very little sleep, we went out to continue our “quest”, adopting the identical tactics as the previous day. Low and behold, 08:00 we had a strike, solid hookup and 25 mins later Donald released his 2nd fish for the comp. It was more or less then that we knew we had it done and dusted. The rest of the day we decided to practice our circle hook skills and had all 6 baits out on circles. That did not produce any results, but at that stage we did not really care if it did or not……………. 14:00 was lines up and……………..GOLD!!

Conclusion:

After each sailfish interprovincial, or any competition we fish, we usually have a debriefing and summarise events in our own way and fasion. I have a saying, “I never lose. Either I win or I learn” In this comp it was more true than ever!!

We learned a lot from this experience:

  1. Experience is worth GOLD!!
  2. Never be afraid to try something different. It may just work…..
  3. Learn how to read changing conditions.
  4. Be willing to adapt to those conditions.
  5. Persistence pays off!!
  6. PREPARATION BREEDS SUCCESS!!

Hope you find this interesting.

Regards,

Len Matthews.


Wowser, what a story! Those Sodwana sailfish can drive you mad sometimes, but Len and crew seem to have it down pat. Thanks again Len

It’s totally wild down there as GoFish blows it up!

It’s totally wild down there as GoFish blows it up!

Gofish Cameras. Totally wild.

When we first reviewed a bunch of underwater recordings shot with GoFish trolling cameras – of fish attack behaviour, that we made out off of the Bazaruto Centre for Scientific Studies recently – some crazy sounds came booming from out of the studio.

More and more gasps and exclamations, hoots and howls from the reviewer – until he crescendoed with an almighty bellow, “COME AND SEE THIS!”

Myself and Callum Roberts (visiting shark scientist and the reason for us targeting Zambezi Sharks as he completes some serious scientific research work at the BCSS) bounded into his office, only to be exposed to the most eye-widening imagery ever seen by either of us. Mainly Zambezis – the particular troublesome species we have been targeting for spatial monitoring and movement tagging.

But also King Mackerel – reckless and lethal as they were hunting in packs – they operate together. Amazing to see. Even the big ones. And when your livebait starts to panic like it would after a few minutes in these waters, make no mistake your bait is being stalked and charged from all angles. What was amazing is that they turn away so often. It’s about one in ten charges – that the ‘couta actually hits the bait. The pack seems to goad one of them into eventually taking on strike duty. And they all hang around and share the spoils after the striker gets the bait off the trace! Which happened surprisingly often.

The Zambezi’s were the same, as in there was never only one of them. Up to six at a time were recorded happily sitting barely two metres below the propellers, easily keeping pace with us as we dragged a dredge and a bunch of lures around behind us, at quite some speed. Obviously, as we had a strike, it was barely a few seconds and a shark would climb on.

The Cobia acted the same. And often swam with the sharks. In amongst them. Huge fish.

As did the Talang Queenfish we were lucky enough to film off of Paradise Island. We scored an unlucky flying fish that flew onto the boat. About 5 inches long. The trace we had was too heavy for starters, but a bunch of queenfish came in and inspected, mock charged, turning away every time. A custom trace with light nylon would have gotten that strike. But we did get one on spoon, which may show a relationship between strike rate and live baits in the water.

Yellowfin Tuna, at these initial stages of fish behaviour analyses, have been the most wary and sensible. The bonito and skipjack footage that we recorded in our wake following us – unbelievable. Like an over-stocked aquarium, there were fish everywhere, and going in all directions!

This particular application of video technology to our favorite past time of fishing has potential to completely shift the way we see and treat the ocean and it’s fish. It was far more of a thrill seeing what had happened as recorded and reviewed through the day than actually catching and fighting the fish.

The following video was compiled to study the king mackerel as they come in hot and fast onto the target. You will see that they definitely come in from the flank or rear, and that they go for the tail first. In this clip, one couta actually removes the tail completely with a lightning-fast strike. And then another of the three featuring king mackerel comes in and takes the bait right off the trace. But he hooks himself. And then, in a flash, he just shakes the trace free. All we could see from the boat, was a few dips on the rod tip. The fish never even took drag, since they were coming in for the strike in the general direction of the boat ie towards us! And for sure the camera was always deployed on a real stiff big gun. Tackle just too much for them. We lost quite a few cameras in the end. Sharks and other beeeeg fish we will never know about.

But basically, without the GoFish camera, we would have experienced none of the thrilling wildlife action going on barely a few metres behind the boat. It really has made an effect on us as we now are using this information to make new sfyle traces. But more about that in another article.

All the imagery we attained on our last three weeks of shooting underwater with GoFish cams, has been processed into data and video and is studies. Some of which you can see online at the following links:
