Spain is definitely the place to go in Europe, if you want to try something different, virgin waters and the chance to catch little known but big barbel. Naturally, the Iberian species have been caught by the Spaniards themselves, but they don’t seem very interested in going into detailed studies of the various species, and therefore much is undocumented and many of the stories about huge barbel widely thought to be exaggerations. 

First time I saw a photo of a comizo barbel (Barbus comizo) in Blinker magazine I really thought it was a trick photo, and I know for a fact, that many other specimen anglers thought the same, but later Blinker ran an article by Arnout Terlouw, who caught these monstrous barbel, so fortunately it was all true – they do reach at least 40 lbs.The comizo is a big barbel, similar in many ways to the common barbel, but having a longer snout, which makes it look a little like a pike, when you see it in the water. Locally it is also known as “pike-barbel” – not far off, when you know more about it, which I will tell more about in the article. 

Distribution & Location
Comizo barbel are quite common in the huge rivers Guadiana and Tajo, but that doesn’t mean they are easily located or caught – especially not the big ones - this I have learned, myself, from many trips with my great friend, Peter Staggs, in Spain. 

In clear water we have had most success with big fish at night and early morning, and even when we have seen big comizo in the daytime, we had no chance to get near them. Daytime fishing is difficult because they are shy, and not due to the warm weather. It is a general mistake to assume, that these barbel will go off feeding during the heat of the daytime hours, because in Spain the fish are basically used to it, and it doesn’t seem to have the effect it does in our part of Europe.

The advantage of clear water is, naturally, that you have a chance to see the fish, the bottom landscape, and where there may be logical feeding areas and snags. In big waters with slow or no current, the comizo tend to have very systematic patrol routes, and once these are found, you can be pretty sure a comizo will be around during the course of a day. In clear, weedy waters you can locate the patrol routes by finding areas, which the comizo deliberately keep free of plants - these are obvious and very visible feeding areas. In running water, the comizo is as fond of water plants as the common barbel, where they have cover, and where they seek food. 

In murky water the advantage is that the comizo is less shy, and doesn’t hesitate to show itself in the surface. Daytime fishing in murky waters is quite feasible, by using the common barbel location techniques and by sight. 

There is one occasion, when the whole “location picture” turns upside-down, and that’s when there is very little natural food to be found on the bottom. Then the comizo aggressively hunts smaller fish, so it is to be located and caught as you would a pike or a trout.
When the comizo hunts prey in the surface, or when it’s playful in murky water, it makes a telltale “swish”-like sound, which is very different from any other fish I have encountered. It is also identifiable by its dorsal fin, which is triangular and relatively small. 

Tackle & Techniques
Targeting the big comizo, we almost always use carp style approach, and most often we fish both the near bank and at quite long distances to get to where the comizo have their patrol routes. This usually means placing the baits by boat. Precision baiting is vital when fishing for comizo in weedy waters, because the weeds can reach more than 3 feet in length, and any bait in that is as good as no bait at all. The comizo search their cleared spots for crayfish and other food, and rarely stray from their usual routes, unless the natural food is sparse or unavailable.
Long distance fishing demands good teamwork, where one angler rows out the baits and the other makes sure to keep the lines tight. The lead must be fairly heavy, so the bait doesn’t get dragged away from the intended fishing area and into the weeds.
Strong rods, strong reels and strong lines are essential to have any chance of landing a big comizo. We always use strong braided lines because the comizo does not hesitate once it is hooked, and finds whatever weeds or snags in area to hide in. The comizo actually make tunnels in the weeds, and needless to say, they use them for escape any chance they get, and then a mono line is not very good news.
The comizo are supremely strong and hard fighting, which adds to the joy and terror of catching them. It has happened several times that they have taken the rod right out of the rodpod even when fishing at distances of 100+ yards. 

I can only emphasize that strong tackle and strong rigs are crucial, as well as strong and sharp hooks. The big comizo are not easily found and lured to take the bait, so every detail counts if you don’t want to lose the rare opportunity of a comizo hit.
If you are looking for good tackle, look no further than Drennan, Nash and Fox for rods, lines and end-rigs, and Shimano for reels. These tackle producers make gear in high quality, which I have been able to trust on my many trips abroad, fishing for the strangest big and strong fish. 

Baits & Presentation
The big comizo have almost all been caught on rock-hard boilies. The reason we use hard boilies is because of the extreme amount of crayfish, where we usually fish. One year there were so many crayfish, that they were literally crawling around on dry land, so imagine what it looked like around our baits. Of course, there is no rule without exceptions, and on one trip my friend Kenth made some nice, but soft, boilies at the waterside. They were truly good boilies, but as they were soft, only he used them – I didn’t want to take any chances and used the proven hard baits. As it had to happen, Kenth was the only one to catch comizo on that trip!
Crayfish flavour is my preference for obvious reasons, but we have had good results on other flavours, for example Mistral’s Remedy. 

Another good bait for the comizo is maize – especially the triple rig, where two strings are baited normally, and the last string is fitted with foam to make it buoyant. This is a true “killer”, also for carp. 

We almost always boost our baits – both wet- and dry boost. I use either the boost that comes with the bait, or simply liver extract, which works well with both boilies and particle baits. After leaving the hook bait in soak for a while, I dry boost it in either crayfish powder or other attractors – making sure both bait and rig is totally covered - and let it harden for a while, preferably in the sun. 

The small comizo are quite easily caught on sweetcorn, maggots and casters. The match anglers in the area use these baits and catch many small comizo, but it happens at almost every match that one or more anglers get spooled by either big comizo or big carp. 

As mentioned previously, it happens that the normal food for the comizo is hard to find, for example the years when the crayfish are few, then the comizo changes its feeding habits and is very hard to catch on standard bottom baits. Under these conditions the best bait is whatever small fish found in the area. A local angler, José-Luis, has caught well on live-baited rudd – rigging the rudd precisely as you would for pike.
The local anglers in Extremadura have also caught whopping great big comizo on both spoon and fly – several between 30 and 40 lbs! 

More Big Barbel
The comizo is not the only big barbel in Spanish and Portuguese waters; far from it. The other big barbel are even less known about, much less documented, photographed or written about. The reach of the comizo is from the river mouths at the Atlantic to about the middle of the state of Castilla la Mancha. From here and eastward, and with very little overlap, the Valencian barbel (Barbus guiraonis) is dominating the rivers and lakes. The Valencian barbel has almost as great a growth potential as the comizo, and Peter Staggs has managed to catch a phenomenal and rarely seen specimen of 24 lbs. I have only caught a small one myself in Peter’s company, but make no mistake; I will be back.
In the same waters, where the comizo live, you can also be lucky to catch both the common Iberian barbel (Barbus bocagei) and the smallhead barbel (Barbus microcephalus). Both species grow to well over 25 lbs, and are just as fun to pursue, fight and catch. Peter has caught them both, and even some heavy specimens.
 

I may have painted a bleak “comizo picture”, but this is only to give you the best chance to land a whopper, should you get the chance. The comizo is a beautiful and strong adversary, and I must admit that it still gives me butterflies when I see big specimens roaming around in the water.
And as you can tell, there are many adventures yet to undertake on the Iberian Peninsula, pursuing the several big species of barbel, which are even quite common. The food and accommodation is cheap and very good there + you have a bonus of a sublime wildlife including nosy wild boar, lynx, mountain goat, and deer and birds of all sorts.
