A high white blood cell count, called leukocytosis, may result from a number of conditions and diseases. Some examples include: Infections, most commonly caused by bacteria and some viruses, less commonly by fungi or parasites.
When water reaches in the 55-60 degree range, the males should be in shallow water looking and fanning out spawning beds, while the females stage out in the closest deeper water structures. Crappie feed more aggressively and baitfish are more active as spawning nears. Try dropping a minnow under a cork into the spawning beds for males. Use a cast and slow retrieve with a CULPRIT Paddle Tail grub for the deeper females. As a general rule, surface temperatures in the 62-65 degree range are almost perfect for shallow, spawning crappie. The females will then move in and around brushy cover.
The best explanation for the crappie's large following comes with its eating qualities. Many anglers proclaim that no other fish comes close. The crappie is a member of the sunfish family and therefore is a first cousin to the largemouth bass and bream. Two distinct species of crappie exist. And both of these - black and white - are found in most southern waters.
