re: I need a crash course in catching P. annularis

Typically that is correct in a small pond but at 7 acres you could have some nice Myers and size.

This time of year they will be deep. Will get shallow in spring and fall.

Shiners seem to work most consistently, but jigs can out catch them 10 fold when they are on. Jigs to try:
bobby
monkey milk, Cajun cricket, black and chartuse.
Tube jigs: black chartreuse, blue and white.
Marabou jigs: black and chartreuse, white

Remember with jigs, the lighter the line class, the better they move and more you catch.

This should get you started. Let me know if you have more questions.
