Brain Power

Are the fish smart or are we dumb?

(A not very serious look at getting skunked)

Flyfishing is one of the most written about subjects on the planet, more than likely at least in part because there is so much that can’t be explained. One generic theme that repeats itself constantly in various writings is that what with all our computing power we can’t get it right all the time.

How is it that a trout, a cold blooded and slightly slimy creature (albeit pretty and much loved one) can outwit us a lot of the time? What is it that means that a fish, with a pretty limited view of the world and a brain the size of a pea can drive us to distraction with its antics?

Hell all we are doing is trying to con the fish into thinking that a simple twist of fur and feather is actually a real and edible food item, surely that shouldn’t be too tricky, I mean we are smart aren’t we?

We have massive brains, computers, graphite fly rods, ultrathin tippet, fancy vests, myriad fly patterns and all that angling literature, it should be a doddle but frequently it ain’t.

Sure if you mess about with fly fishing for very long you start to realize that there are various means at the trout’s disposal to avoid making a mistake. The colour, shape and size of the fly being used, the presentation and of course that all important little corollary the onset of unnatural drag to give the game away, but still come on we are at the top of the intellectual food chain here, we should be winning the race.

Many people, both anglers and non anglers alike keep asking me “but surely the fish can’t be that smart”, I mean really they can’t actually learn stuff or process information in an organized cognitive fashion the way that us smart and highly developed hominids can manage?

Well it would appear that our arrogance once again proves to be a failing; recent research into the ability of fish to feel pain, (another generic theme that runs through angling literature on a regular basis) has apparently shown that fish can learn a whole lot more than we previously imagined. Of course if you have a PhD and torment fish in a laboratory your opinion is perceived as more valid than if you simply spend a lifetime trying to catch them, but I don’t need a doctorate to know that at least some of the time my best efforts aren’t enough.

That trout can learn is, at least to my mind, more than adequately explained when you watch the change in behavior over time on waters that are transformed into Catch and Release venues where the fish have the chance to add to their experience without paying the ultimate price for the first error of judgment.

Over time the rise forms become more subtle, refusals of the artificial fly and inspection rises to have a better look at what is on offer become more common and what the English refer to as “short takes” catch us out on a far more regular basis.

The evidence may well be subjective but the sheer volume of it has to stand for something and for my money the fish are getting smarter and they are becoming more and more tricky to fool. I have heard it said that trout aren’t hard to catch because they are smart but because they are too stupid to recognize a good thing when it comes along and simply eat the same old same old one after the other during a hatch. I don’t buy that for a moment apart from anything else I need to believe that they are smart to justify my own failings. It is one thing to be skunked by a highly evolved self protective mechanism in a thinking fish, quite another to admit defeat at the hands, or in this case fins, of an unworthy opponent.

However having spent years pontificating on the subject I have come to the realization that there is indeed an explanation, one so remarkably succinct, so simple , so logical that I absolutely had to share it.  Our brains are in some ways our biggest limitation, we look for complexity in everything, even when it isn’t there.

So perhaps the following charts of what goes on in both human and trout brains during the day will offer some explanation, perhaps a little solace and if nothing else a valid excuse for those days when your net remains dry.]

So there you have it, that is why, when you are struggling to come to terms with failure and the world is on your shoulders you can’t get the fish to take. In the end perhaps the most important part of fishing is to clear your mind, it may give you something of an edge when you get right down to it.
