Basic philosophy
Posted: Tue Mar 05, 2013 12:41 am
As I still get quite a few e-mails on various stuff I have posted here and elsewhere, here are a few musings which might be informative as to why I do some things as I do and avoid others.
> so its all just guessing anyway?
Well, basically yes, but educated guesses are always better than random guesses. Just assuming something or other probably wont do you any good, and will in fact probaby be detrimental.
The point is that you don't know many of the variables involved, indeed, you simply can't know many of them, but you can make very accurate guesses based on other data. This is why your observations need to be accurate and your testing as good as you can make it.
What you are trying to do is find out what is most likely to happen in a certain set of circumstances, and be able to repeat it with the object of catching fish.
Random guesses or assumptions, just like random flies, wont do you any good in making accurate predictions. Some may work but you have no way of knowing why, or how to repeat it. Any guesses you make about it are based on limited data. It is the repeatability under certain circumstances which you can recognise which is important, not whether any particular random fly sometimes works at random.
My philosophy summed up as best I can is basically this;
Trout ( and of course other fish), eat various prey.
If I imitate that prey well enough trout will probably eat it.
If I am in the right place at the right time with a good imitation of that prey and don't do anything to alarm the fish or set off its instinctive defenses I will probably hook it.
Everything I do is set up to achieve that. The design of my flies, the methods of presentation, the emphasis on stealth, everything.
That sounds simple enough, and it basically is, the difficulties arise in learning all the things necessary to achieve it regularly. You are playing probabilities, and attempting to load the dice in your favour. If you don't load the dice, or not as well, then you wont succeed as often. You will still probably catch a fish now and then but not as often as if the dice were loaded favourably. If you use random methods or execute poorly then the dice are in fact loaded in favour of the fish.
You can never predict exactly what will happen in any given circumstance, but you can make general predictions based on the data and knowledge you have and on the system you are using. If you have limited or no data and knowledge, then your predictions will not be accurate. If you use random guesses and assumptions then your predictions will not be accurate.
You can not control the environment, or your targets, but you need to be able to control the system you are using in that environment or you can not load the dice properly at all, nor can you test your results with any accuracy. Flies themselves are only a means to an end. They are there to imitate prey. They are not there to "fool" a fish, that implies that you are relying on a fish making a mistake, which it is basically incapable of. An instinctive reaction can not be considered a mistake. If you get things right the fish is never aware of anything at all except something natural to eat in front of it. If you do not trigger its defensive instincts then they never come in to play.
Although this is constantly discussed I have never found a "positive trigger",( excepting some movement on some occasions), with regard to artificial flies. In the majority of cases, when a fish takes a fly it does so because it wants to eat that fly as part of its normal behaviour. If it senses no "negative" triggers, ( things which will alert its instinctive defenses), it simply does so without any fuss and bother. You can not know why a particular fish behaves in a certain way in certain circumstances, but you can observe that it does so. Of course you can make guesses, but if you try to base these on human experience and emotions you will invariably be wrong. A fish is not a human and is not subject to human emotions or behavioural imperatives.
Trying to base your fly designs on various unproven ideas and theories doesn't work well. It may work occasionally, even quite often, depending on circumstances, but you don't know why or can only make vague guesses based on limited data. There are a few "general" flies which work well under various circumstances, in my opinion this is because they resemble some prey well enough for the fish to take them in those circumstances. This further strengthens another theory of mine that fish dont actually "see" very well at all in the sense that many people mean it. What you see is integrated in your brain, lots of things affect it. Your final perception of the signals that reach your eyes is an extremely complex perception. It does of course depend on how well your eyes work to begin with. There is no way to know what a fish sees. You can extrapolate from its physiology what its organs are physically capable of but "seeing" is much more than that. It is an integrated sense that is interpreted by the brain. In humans, people often see what isn't there as a result of habit, previous experience, etc etc. There is no way, ( as yet) to know what a fish sees despite the amount of research and discussion on it. I think that in a lot of cases fish simply see what they expect to see regardless of what is actually there. Just like humans. As fish have no reasoning powers this probably happens a lot and also is an indication why fly fishing functions as it does.
Can fish see in the UV spectrum? Do they have colour preferences? Is there something ( excepting movement) which would "trigger" them to take an artificial? I have no idea, but as I know of no way to use that knowledge even if it were true, I simply ignore it.
