Russian expedition - part I


In 2010, Saša got acquainted with Dr. Oleg Askeyev, the head of Biomonitoring Laboratory at the Institute of Problems in Ecology and Mineral Wealth, Tatarstan Academy of Sciences in Kazan. He found out about us via this website. Due to our common interests, we saw a potential of mutual collaboration; in August 2011, Saša, Matjaž Červek (my outdoor buddy) and I responded to a Russian invitation for a 14-days expedition to pre-Ural area in Tatarstan, Orenburg and Bashkiria, in the first place to perform Thymallus thymallus sampling, which took place in the middle Kama and upper Ural river systems.

 > The expedition team: Igor (Oleg’s twin brother, ichthyologist), Aleš, Oleg, Matjaž, Saša, Sergey Monakhov (ichthyologist, PhD student), Rustem the driver, Dmitry (biologist and excellent cook in the field) and the famous UAZ 4WD van. Saša Belayev (small mammal  expert and curator of the Natural history museum) is taking the picture.

From my perspective, the celebrity of this expedition was grayling; we found them in small headstreams, which are in Slovenia normally populated with brown trout only. This is only one of several differences that make the Caspian grayling distinct from the Sava ones.

Net was the main fishing tool; quite some skill is needed to use it effectively.

Nejc presented his Diploma work


In September, Nejc has accomplished his diploma work “Taxonomic analysis of bullhead (Cottus sp.) in Slovenia with application of molecular methods” and presented it at the Department of Biology, University of Ljubljana.

Diploma highlights: •mtDNA analysis revealed the distinctness of C. metae and supports its classification into a new species •considerable phylogeographic polymorphism was found in the Western Balkans possibly giving rise to new species •two major colonization waves of bullhead to Europe presumably started in the Western Balkans

During his diploma stage, Nejc was brought face to face with the concept of minimalism.

Staff changes and other important events


Anja defended her PhD thesis in April, 2012, “Molecular ecology of imotska gaovica (Delminichthys adspersus (Heckel, 1843))”, a minnow-like fish, endemic to karstic environment of the Western Balkans. They are found only in springs and associated subterranean waters. In many locations, gene flow is maintained across geographically separated populations despite the absence of superficial interconnections of those waterways. Anja concluded that the only apparent explanation for this is subterranean migration of the fish between populations, a phenomenon never before documented in epigenic fishes.

A part of her work was published in Molecular Ecology, and the picture of the studied fish, taken by Arne Hodalič, appeared as the cover image of the journal.


Two others publications came out as a result of this study, one in Journal of Biochemical Systematics and Ecology and one in Ecohydrology.

She just left afterwards.

Introducing Nejc

Named Nejc after Neal Armstrong, the greatest man who walked the faces of Earth and Moon (not at the same time). Currently finishing Biology at Universitas Labacensis. In a year and a half I will be on the job market, so anybody interested in me can send an e-mail to bravnicar.nejc@gmail.com

Important information about me: if I was a Transformer, I would be a yellow VW T3 van (Transporter Transformer) with cool Cottus gobio stickers on the hood. C. gobio is a super cool benthic fish and the subject of my graduation thesis. I will try to determine phylogenetic relations between different populations of probably two different species of the Cottus genus. Aleš Snoj is my mentor, I know you are all familiar with his work and describing him would just make me look like an ass kisser. And same goes to all members of BTRG, especially my working chief Anja. Glad to be on baord.

Visiting Johannes

Saša, who is staying in Slovenia at the moment, Aleš and his wife Nada visited Johannes Schöffmann and his wife Ida in St. Veit, Austria. We admired Johannes’s rich collection of stuffed salmonids exposed across the living-room wall and enjoyed a lunch prepared by Ida. In the evening, we tasted delicious cakes from Franz Schöffmann Bäckerei und Konditorei, made by Johannes himself.

Inspired by beer and wine, we were discussing Moroccan trout and planning future projects and field trips…Algeria seems to be the next tempting destination.

Unfortunately, most of the taken pictures were accidently deleted from the camera.

LIFFe 2009

LIFFe stands for Ljubljana International Film Festival. To be honest, most people still refer to the festival as LIFF (especially those who are aware of the meaning of liff). As mentioned last year, BTRG selects a movie with a fish related title. There were 5 movies to choose from this year, last year's winner was Encounters at the End of the World, this year it was Fish Tank. There is hardly a place for fish in an English social drama, but several things were unexpectedly connected to our work. For instance, there actually was a fishing scene and a memorable "fish are stupid" quote. The main actor was Michael Fassbender, who also played in Inglourious Basterds, last movie we saw as a part of team building. And of course, the main music theme was Bobby Womack's version of California dreamin', a very appropriate song just 2 months before Urška and Aleš will represent BTRG at the Plant and genome conference on a winter's day in the same state.
Anyway, Tamara, Urška and Andrej attended this year's LIFFe event, along with Daliborka and her team as special guest stars. Anja and Aleš were absent at the last minute notice due to emergency sampling expedition. In the boss's absence there was enough time for conversation and some gossiping after the movie (until the waitress kicked us out).

Introducing Klavdija

Klavdija Bogataj is an undergraduate student of animal science and is currently preparing her graduation thesis "Genetic analysis of autochthonous brown trout (Salmo trutta) in Slovenija and identification of genetically pure populations" (working title).

Her practical working experience as a part of animal science curriculum at the Angling Club of Tržič was followed by sampling expedition with the Fisheries Research Institute of Slovenia. After realising that sampled fish are studied by Aleš Snoj she asked him for a graduation thesis mentorship. At the end, Simona Sušnik became her mentor. Klavdija started to work in the laboratory in October 2008 both for her thesis and the autochthonous brown trout project. As the later is done under a scheme similar to summer work she will probably be one of the few people actually working in the lab during the summer.

Introducing John

John Zablocki is a recent graduate in Chemistry and Spanish from the University of Montana. He came to Slovenia this September on a Fulbright grant for his project titled "Characterization and conservation of endangered Balkan trout". His first several months in Slovenia were spent working in the Marble Trout Restoration Program in Western Slovenia with the Tolmin Angling Association (Ribiška družina Tolmin). In January he moved from Tolmin to join our lab and is currently working on a project to possibly identify a remaining pure population of Marble trout that were thought to have gone extinct.

He is obsessed with trout, language, fly fishing, and conservation. He plans to continue working in the Balkans to help protect its unique and fragile salmonid biodiversity.

Vrljika field trip, March 09

In a frame of collaboration with prof. dr. Ivan Bogut from Osijek University, Mr. Ante Mikulić, a representative of Angling club Proložac and our old friend Dušan Jesenšek from RD Tolmin, BTRG organized another field trip to Imotsko polje, in the first place to sample minnows. We were again accompanied with a photographer Arne Hodalič and also with his friend Matej Mihailovski; they were mostly interested in taking photos of the Vrljika softmouth trout and Red Lake scenery.

It was also our intention to meet Manu Esteve and John Zablocki there, who were in the mean time trying hard to film spawning behaviour of the softmouth trout in the neighbouring Neretva River. Unfortunately, we somehow didn’t make it and we are now trying to organize this meeting in Slovenia, were Manu is currently making a stay waiting for Hucho spawning.

An interview and a fishing story

James Prosek was interviewed by The Itinerant Angler, you can also download the interview (mp3, 41 MB). Among other things he mentioned our group and one of the more memorable field trip. He mentioned that he personally wasn't there, but Steve and Aleš often entertain us with the story.



Fishing story

In 2004 a field trip to Montenegro was organized, involving people from Austria, Slovenia and Serbia, along with local biologists and fisherman. The primary motivation for this trip was to search for the extremely rare and perhaps extinct form of softmouth trout from the Zeta River. The group was well equipped to sample trout, bringing several experienced fly-fisherman, an inflatable boat, and a 5 KW stationary electro-fishing generator, lugged all the way from Austria. The first glimpse of the Zeta generated quite a bit of excitement in this fish hungry crew. The river was surprisingly large and deep, lined with overhanging trees, and teeming with invertebrate life. While we did not necessarily expect to immediately find softmouth trout, we assumed that other trout would be plentiful. However, it quickly became painfully obvious that our experienced and well-equipped crew lacked a certain something necessary to catch Zeta River fish. The first reaction was natural – there are no fish! But each evening around sunset a local guide, Mlađen, who was observing us with some amusement the whole time, slipped away from the café veranda overlooking the Zeta - within an hour or so five or six plump freshly brown trout were slapped down before our eyes. Suspicions, confusion and frustrations were being muttered among us before the fourth evening when Mlađen offered to take Steve along and open Zeta’s door of enlightenment. Some may have thought there was a pond or hatchery around the bend that Mlađen would finally reveal, but instead he pulled one shy trout after another off the bottom of the Zeta with a Tyrolean nymph rig, sometimes from the same run where Steve had just thrown the same rig, 20 times. The rig was key, but not in anyone’s hands as it seemed that only Mlađen had some kind of Dr. Dolittle-like bond with Zeta’s trout. Nonetheless, even he could not come up with any softmouth, are real quarry.

Nearing the end of our week, the pessimism had reached its peak and some of us took a side trip to visit the famous monastery Ostrog, nestled into the high cliffs of the upper Zeta valley. According to common belief, wishes made in certain holy nooks of the monastery can come true. Maybe this is really so, because later in the day upon returning to the river we were approached by a local man who had heard of our struggles to find softmouth trout. He claimed to know where some were, in a small tributary of the Zeta, a few hundred meters from that all too cosy café on the banks of the Zeta. This was our last chance, though we were skeptical. Our skepticism increased as we gazed into the little stream’s clear waters which, like those of the Zeta, revealed no image worthy of even a mirage of a trout. But Johannes, the Carinthian baker who doubles as one of the more well-known explorers of exotic populations of Salmo, quickly donned his snorkelling attire, and made a survey more reliable than any we could have managed with fly lines or electrofishing gear. There were indeed softmouth trout in the stream!

Now we just needed to catch a few. A circus-like atmosphere soon developed, as we dragged the inflatable boat and electro-fishing gear across a meadow, attracting not only an increasing number of people, but a local television crew as well. As fate would have it, the Zeta softmouth, like the Zeta brown trout seemed immune to electricity, managing to stay on the move and just outside of the field around the anode, as if they were well trained. Our growing frustration was being intently monitored by Đoko, the guy who told us about this secret location. Afterall, he had PROMISED we would catch fish. Suddenly he couldn't stand it any more; he slipped into his wet suit, complete with mask, snorkel and fins and waded slowly into the shallow borders of an otherwise three meter deep pool. Observing his gesticulations, we slowly realized what his intention was: he wanted to dive with the anode pole in his hand and try to “harpoon” the fish with the electric field from a close distance. As the vision of this Rambo-esque plan unfolded in everyone’s minds there were varying degrees of resistance, ridicule and shock. With television cameras ready to roll, a multilingual cacophony rose around the pool as each person attempted to define their level of involvement, ranging from pure disassociation to neutral curiosity and on to legal culpability as expressed by Steve who had organized the Austrian crew and University owned electric-fishing set-up. He screamed: “No, no, no…!” But Danilo, from the University of Montenegro tried to explain to Steve that the man had indeed promised we would catch softmouth, and thus, by some rural code of honour he was determined to deliver, and there was nothing we could do to stop him. The decision was made to proceed, but with pre-determined hand signals and a hand on the off/on switch of the generator. Đoko finally got hold of the pole and quickly dove into pool. His hand went up, signaling for the juice, but he quickly emerged shaking his head in disappointment as the generator was correspondingly shut off. He dove again, gave the sign and everyone gasped at the sight of a swirl and a few bubbles – the electricity was only on for a few seconds, but Đoko emerged triumphantly with a softmouth trout in his net, igniting a cheer and celebration on the banks as if a golden-goal had just crossed the net. The act was repeated and several softmouth were landed in a similar fashion.

There were long debates on the dangers and dynamics of electric currents in water, of grounds and wet-suits and insulation. The popular outcome of this action was most likely the result of the fact that the man was indeed quite distant from both the anode and the cathode, with the electric field held out several meters in front of him at the end of a long anode.

P.S. Please note that the authors adamantly discourage anyone from repeating the actions described in this story. Fishing with electricity can be dangerous and should only be done by licensed operators, and all safety regulations should be followed, which in most countries explicitly forbids any form of diving during a sampling action.

LIFFE

LIFFE stands for Ljubljana International Film Festival. Four years ago we were checking the programme and saw a movie with a very fish related title. So members of the BTRG went to see Fickende Fische (Do Fish Do It?). The idea was good and worth repeating. The following year we waited too long to get the tickets so we went to see a movie with absolutely no fish related subject, Les Poupées russes (The Russian Dolls). Last year it was Sonhos de Peixe (Fish Dreams) and this year we selected a documentary Encounters at the End of the World.

4 core members of the BTRG went to see the movie plus 1 special guest star, we also met 2 former co-workers in the cinema. About the movie shot in Antarctica.... It is not a "fluffy penguin movie", more a series of interviews with "professional travellers and occasional workers", and weirdo scientists. We now understand a little bit better what people we meet on field trips think about us and our work.

Introducing Gašper

Introduction of the new member of BTRG, PhD student under "Young Researcher" program, financed by the Slovenian Research Agency for the next 4.5 years:

My name is Gašper Pustovrh and I study genetics. I love to do things that involve water - like fishing, underwater fishing, free diving, etc. I graduated from veterinary medicine I already as an undergraduate student I knew I want to work with fishes. That is why I applied for a young researcher at the Chair of Genetics, Animal Biotechnology and Immunology in the Balkan trout restoration group. I am trying to find new markers that can differentiate Marble trout from Brown trout which is of great importance in preservation of the Marble trout.

New PhD

Tamara Rozman successfully defended her PhD thesis "Characterization of transferrin locus and its application in phylogenetic analysis of genus Salmo", available here. Transferrin was the marker of choice because mitochondrial markers and microsatellites (frequently used nuclear markers) have several limitations when used in phylogenetic studies. A major problem was ancient tetraploidization of salmonid genome resulting in two actively transcribed transferrin loci.

Tamara was involved in this project for a long time, partially because of this and this reason, and also because the study was carried out on third generation of marble trout × brown trout hybrids (generation time 2-3 years).
