This is really an in-depth hobby/field.
Increase your ISO to 400. Try to get the shutter speed to at least 125. You could also use shutter priority and let it set the aperture for you however I prefer full on manual. Increasing the shutter speed will stop the fish a little better and reduce camera movement. ISO 400 is a good all around setting. 200 a little better of course. 100 usually leads to too slow a shutter. IMEO
