I wouldn't get to crazy over this as a newbie. Light is the biggest issue, better light gives you the ability to quicken the shutter speed and you'll have generally sharper images of fish. Aperture is something that needs to be adjusted for light, but light is still key. Sweet spots on lenses are much further down the list. Your kit lenses can produce very good images with enough light.

Yes, you are correct. I meant when you "increase" the aperture value not when you "open it up."

You mean decreasing the value. Remember they're fractions. Why is life so complicated.

Haha, words! However you want to say it, when the aperture is a larger number like 9 instead of 2 you get more in focus and less light enters the lens because the hole is smaller.

Aperture is not the same thing as shutter speed. Shutter speed is the fraction, so 1/10 is much slower than 1/100. The 1/100 is only open for 1/100th of a second so less light enters and you "freeze" fast movements.

In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture[1]) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil.[2] It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography.

http://en.wikipedia.org/wiki/F-number

The aperture determines how much light hits the sensor/film. Shutter speed determines how long that amount of light is allowed to hit it. One is quantity the other is time.

Bryan Peterson's book has already been mentioned. Let me also mention Scott Kelby's series of books on photography.
He teaches you how to get the shot without all the tech stuff. Great to get you started but it's a bit like synthetic fertilizer vs organic. One feeds the plant the other feeds the soil. Stop feeding the plant and it withers.
