The Guadalquivir is a hell of a river. It is over 400 miles long making it the fifth longest in the Iberian Peninsula and the second longest to keep itself within Spain and not to go wandering off into Portugal.

We spent a couple of days fishing the upper part of the river around the town of Mogón and further upstream into the section that falls within the Parque Natural Sierras de Cazorla, Segura y Las Villas.

You should see the river here. It is just beautiful and it provides the wild trout with everything they need; cold, clear and richly-oxygenated water that conveys the aquatic invertebrates and terrestrial insects that they need to sustain themselves. Continue reading →

Every now and then my wife tells me off for using bad language. She points out that a blog post is no place for profanities and so I will refrain from using them in describing the tiger mosquitos that are causing a plague on the lower reaches of the Guadalhorce river.

Tiger mosquitos are not endemic. They hail from Southeast Asia but they have become quite widespread as a result of their association with humans. I must confess I did not know very much about them but am now a little wiser having read about them on Wikipedia. The article usefully pointed out that they are not to be confused with tigers which, apparently, are wild mammals! Continue reading →

I don´t know about how high the cotton is but fish are certainly jumping, or at least they were last Saturday. The Guadalhorce was looking good after having been shaken up a little by recent rains. The fish were in the fast water and I managed to catch some barbel, 10 I think, in the faster stretches.

Heading back home I stopped to take in the view of the fish milling around in the water at the foot of a weir. There were mullet, gypsy barbel and carp all packed together just behind the white water. Continue reading →

On the way back from the river the other day I nearly walked on a turtle. At the time I was clambering over some rocks and just before planting my foot I realized that one of the rocks looked odd. It was. It was a turtle that embarked on what, from a turtle´s point of view, would have been a major mountaineering adventure. Continue reading →

Up in the Ebro you can catch catfish that weigh a couple of hundred pounds and must be the best part of 10 feet long. They have mouths that could swallow a football.

The prospect of catching these great lumps draws people from all over Europe and, for many freshwater fisherman, they represent the ultimate catch – the ultimate catch, that is, if you want to catch something bigger than you are, or if you want to brag to your mates. Continue reading →

Perhaps it never occurred to you to ask this question but the answer, to the best of my knowledge, is no. Fish do not play golf. The question arose yesterday in my Science lesson with Year 7 and was in response to some interesting commotion taking place in the fish tank at the back of the lab.

First, let me tell you a little about the fish tank. It is about four feet long and has one pretty sizeable fish in there, a species of pleco. The pleco is one of a small number of common aquarium fish and I understand that our one is Hypostomus plecostomus, a nocturnal catfish which is native to South America but has been widely introduced elsewhere.There is also a bunch of goldfish which found a refuge in my tank when the school pond was drained for refurbishment. The pleco must be about a foot long and a lot of people have questioned whether it is a good idea to have such a big fish in a relatively small tank.  Continue reading →

There is a lot to be said for goats. They wander round in flocks ringing their little bells. I bump into them on the river all the time and yesterday after I was done fishing I followed a herd back to the car where we parted company. I don´t know how many there were and, frankly, I had better things to do than count the damn things. This is not an easy job anyway. They move around a lot and so you could end up counting the same goat twice or maybe miss one completely. This is a job best left to specialists, in my opinion, or to insomniacs who find the counting of ruminants helpful in ameliorating the stresses caused by sleeplessness. Continue reading →

I had no time to go fishing yesterday but went anyway. I figured I needed to be home within an hour and that the journey to the river would take 10 minutes, then another 5 minutes to tackle up, and then another 5 to reach a broad shallow where you can find the odd carp. And of course the return leg would take just as long. All of this mental arithmetic was carried out on my way to the river and the upshot of it all was that I would have only a few minutes to try to catch anything. It didn´t matter a jot though. I was going fishing anyway. Continue reading →

It pissed rain last night and the unrelenting downpour was such intensity that it would get the Noahs of this world asking themselves “have I got two of everything?!” There was lightning too and claps of shuddering thunder that had the dogs scratching at the front door. And then today began with open clear skies and a warm sun. Puddles on the track outside mirroring the blue sky were all that gave testament to the dramas of the previous night.

The river was swollen with rainwater. I brought the rod when I went to look, first at the Guadalhorce and then at the Río Grande in the vague hope that a quiet eddy might have a few fish I could try for. I lowered my rod top into the stained water to test the visibility and it was no more than an inch or two and it soon became clear that fly fishing was a simply not on the cards. Continue reading →

The fish had the last laugh on the river this afternoon. The only one I did manage to hook flew off as though he had been fired from a cannon and then buried himself in a pile of weeds. When I finally caught up with him and waded into the river to extract my leader from the weeds he got away. Good luck to him. You can´t beat a bit of initiative. Continue reading →
