Move slow and deliberate. For each carp or gar you see making ripples, there will be 3 laying still that will scare the urine directly out of you because you had your eye on one up ahead that was splashing around. I call these fish 'sleepers'.
I often wear a pack when I bowfish cause if the shooting is hot, you can cover miles of shore or creek...right, Patrick?
In my pack I carry water, an extra arrow or 2, a multitool, knife, a camera in a waterproof box or bag, tweezers...cause I like going barefoot, and a file to touch up points that contacted Rock Carp.
For most shots, I aim at the bottom of the fish. Gar will test how good your estimates are! Long shots require aiming high, yet refraction requires you to aim low. Luckily My waters are pretty murky so I can't see but 6 inches deep or so.
If you spook spawning fish, you can often get another shot, as they sometimes don't go far. Buffalo just run a circle and offer themselves up again.
The Leviathans...the really big fish, are tough to catch out in the daylight. You can still wade around with a lantern and shoot em at dark tho.
Fish arrows and safety slides can be made for a lot less than buying them. Saves a lot of loot if you bowfish rocky areas!
Good luck!
