+ 1 on the Moon Phase! Google it, Get an App on your Cell Phone. Water Temp (-April +May + moon phase thru July) can help with targeting bedding fish like Bream/Shell Crackers. My best luck has been in managed ponds (Blessed by the Fishing Gods), but there were days out of cycle where we could catch a carp with 30-06! Then on days in cycle caught so many that I haven't been to one pond in 4 yrs and still have excess bream in the freezer! Try it. Works on deer too.
