Chub versus trout?

Luxurious fly-fishing blog
In the latest – autumn issue of Pêche Mouche one of the authors inserted an article about fly-fishing for white fish. This is indeed an interesting alternative, in particular in months when both trout and greylings are protected (whole 3 long months in Luxembourg!). One of the fish mentioned is naturally the chub – it turns out that in the past many French fishers considered the chub to be in direct competition with the trout and killed every one hooked, leaving them on the bank (the meat is considered not to be very tasty). The author says their assumption about the chub competing with trout were false but, unfortunately, doesn’t present any arguments on which his own assumption was based. The issue is of particular interest to me as, especially this hot summer, I saw the whole lots of rivers completely dominated by the chub, with no sign of trout presence.

60 cm Alzette chub, how many little trout were in his stomach?
 I do not pretend to be an ichthyologist but I consulted one and read some articles on the web: the early conclusion is following: the chub can be and often is a menace to trout population. Let me cite you just one article concerning Irish waters:
Chub, a popular coarse fishing species in Britain, has already wiped out native trout on one of the most popular trout fisheries in Co. Westmeath. The problem poses such a threat to other trout waterways that the Minister for the Marine, Noel Dempsey, will next month introduce emergency legislation to prevent the introduction of chubb to Irish trout waterways.

Nice Sure trout, this one is rather safe from the voracious chubs
Yes, both species compete for the same food and habitat and it would be probably naive to think they don’t affect each other. With the difference that chubs are much more tolerant to unfavorable environmental conditions and can survive even in a very polluted and warm water. I saw myself many trout ‘hot spots’ occupied by big hoards of chubs ranging from 30 to 60+ cm. No trout could penetrate there.
When chub and trout are side by side competing for habitat, the chub will always win” 
The question is now, how to deal with this situation? I don’t support killing the unwanted fish (i.e. chubs), apart from it, they are simply too numerous. A good starting point would be a solid research project evaluating the potential threat posed by the chubs in Luxembourg and monitoring it’s influence on other species. This, however, is only a dream, as mentioned in an earlier post, here even the most basic data are kept secret and there is no sign it could change in the near future. If no effort at all was taken to deal with gobbies in Moselle, what to expect?

 

Green energy?

chub

This poor dead 50 cm common nase (or nasel) was spotted today in the Sure. As it didn’t show any signs of being hurt by cormorant, etc., the question arises, what happened to him? One possibility is that it became another victim of the Esch-sur-Sure dam and sudden releases of water that are so deadly for every living creature in the Sure. It’s really a pity that 3 of the most important Luxembourgish rivers: Moselle, Sure and Alzette, were so badly managed in the last century. It’s difficult to imagine what the Sure was before the construction of the dam, the task is easier with the Moselle – one hour drive in France and you can already see a nice river which has not been canalised (with such a dreadful consequences).

This is a very big specimen and it is really a pity it had to die.

Summer fly-fishing: can it be effective?

Luxurious fly-fishing blog

Calendar says we still have whole month of summer before us so the question remains valid. I recently read a section of the Orvis’ Guide to Fly-Fishing beginners (by Tom Rosenbauer) when it is argued that fishing in warm and shallow water is perfectly possible and even “can offer the most interesting fishing of the season”. The author gives a piece of advice how to succeed in these conditions, this can be summarised as follows:

  • Fish at the dawn, when the water is coldest
  • Keep your profile low and movements slow, wear camouflage clothing
  • Look for fish in fast riffles or behind the boulders, don’t omit entries of tributary streams
  • Use small flies, 18 size being maximum
  • Light rods (below 5) and tippets

I can well subscribe to all this with the caveat that it doesn’t guarantee anything at all, at least in the local rivers. I know parts of the Upper Sure where no tricks can help you when the water temperature is above 20 degrees and the sun is shinning strong. Apart from it, don’t expect anything bigger than 20-23 cm in a water which looks like this:

Yes, I know some places where fish stay whole year but these are very rare and are normally overcrowded. I also noticed that sometimes when nothing else works trying natural size mayflies brings surprising effects, exactly in the summer. Nevertheless, hot summer is definitely the worst part of the trout season and I cannot really guess how can it be considered the ‘most interesting’ one.

Fishing policy in Luxembourg: some issues

Luxurious fly-fishing blog

In the July issue of its magazine, the local fishing organisation (FLPS – www.flps.lu)  has raised many important issues concerning the developments in the fishing environment in Luxembourg. They talk inter alia about such subject as:
– removing artificial obstacles preventing fish migration, among which the most important is the dam in Rosport;
– re-naturalisation of creeks and rivers (almost all bigger rivers in Luxembourg were unfortunately de-naturalised);
– cormorant plague.
They seem to have a very reasonable approach but it also appears that the government turns a deaf ear to their appeals. For me one of the most interesting aspects was the lack of reliable information concerning fish population in local rivers. I know that electrical fishing takes place regularly in different waters throughout the country yet, for the reason I completely ignore, the results are not made public. I tried to obtain this data by writing to the the responsible body (Administration de la gestion de l’eau – http://www.eau.public.lu/administration) but, naturally, got no answer. In the era of open linked data one cannot really understand the fact of hiding the information obtained for taxpayers’ money. The only source of information so far is this book:

It’s very interesting but the latest data about fish populations come from 2005 so have now only historical value (as rightly remarked by the FLPS). For example one of the dominant species featuring in the book is perch, while in recent years it’s often easier to catch a salmon then a little perch in Luxembourgish waters. Chub, which has now completely dominated most of the rivers, only appears on distant places numbers-wise, etc. It is time now that the water administration makes the data available to the public following the modern open data principles. The prices of fishing licences are supposed to be increased, it would be fair to allow the fishermen to make an informed choice whether to buy a licence: it is up to them to decide, whether they want a licence for the Moselle where probably 95% of fish population is composed of round gobbies (grundel), etc. This could also show the evolution of fish stock, whether the measures taken to protect fish (for instance water treatment stations) bring the expected effects, and have many other benefits.

Noteć Forest in Poland

Luxurious fly-fishing blog

I normally try to go at least once a year to Noteć Forest (Puszcza Notecka) in Poland, an area said to be the least populated in Europe. This can be true, judging from the map:

There, without any effort, you’ll see castors, eagles, cranes, etc. Fish are also there but the summer time is not the best one for fly-fishing, as we all know it. However, I did take two rods, 8 and 4 strong this time. Unfortunately, the conditions in my lakes were hopeless, high temperatures all the time, water at 28 degrees Celsius, so I had no choice but to do some spin fishing. Pikes were completely passive, except for the ones like this:

Perches were much more active but only around 5 a.m., no mercy ;). I had some decent ones like this below:

 But the biggest surprise was when I did some worm fishing at the end:

I had some nice tenches, the fish I caught only once before, in Echternach lake. They are said to be very cautious but these ones were quite aggressive and took the worms like crazy. All were returned to the water, I was probably only one there practicing C&R but anyway. The question is now where one can regularly fish tenches in Luxembourg and how to do it with dryflies?

Giant grayling

Luxurious fly-fishing blog

I often fish with a colleague who has longer experience in fly-fishing. He’s an expert in barbels and greylings, The first ones are beyond my reach so far as I hardly use nymphs, but I do always try to catch some graelings (they are unexpectedly numerous in the rivers here). So far, however, my results are mediocre at best, I only had 3-4 this year. Probably the size of flies has a lot to do with it, when I fish in the sun I must use bigger flies to see them. My colleague catches them much more often and his last fish is great also literally, almost 50 cm! Of course it was released in good shape.
I support a size limit for taking fish home say maximum 40 cm for the trout and greylings. Bigger fish should be released, as well as those not having the minimum size, naturally.

Fly fishing 2015

Luxurious fly-fishing blog

Above is my first true video dedicated to fly-fishing in Luxembourg. So far I was only publishing tubes around spin fishing but from now on you it will be rather with the flies that I will intend to seduce the fish. As mentioned in the video the Spring was quite generous, I could fly-fish even up to 30 fish during a short 4-hours session. Yet, then came July, the hottest I remember here, one day I measured the temperature and it was 24 degrees in the Upper Sure! The fish we were taking out were so tired that even after a short fight they would need a long therapy for a full recovery. I hope the temperatures will lower a bit in August,otherwise I’ll have to wait for September, the last month for trout!

Welcome!

Luxurious fly-fishing blog

Hi,

Welcome to my new LUXurious Fly-fishing blog dedicated to the most beatiful fishing method in Luxembourgish waters. I fly-fish in the Éislek which is Luxembourgish name for the northern part of the country, wild and full of trout and grayling -type streams and creeks. I’ll regularly post here not only reportages from my fishing trips but also news concerning fish and fishing in Luxembourg and neighbouring countries, summaries of articles in the fishing press, some research results, etc., in brief, it should be quite interesting.

To tease you a bit please find a photo of a nice shoal of 30+ trout released this year into the Northern waters.
