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.
Finding the right depth is key to crappie fishing. I am able to fish anywhere from 1ft deep to 8ft deep with this setup. I also use a 12ft bnm jig pole and fish the jigs tightling with no bobber. I simply tie the jig about 2ft above the end of the line with a palmar knot. Then I add a drop shot to the end of my fishing line under the jig. You can find the finess drop shots at www.bassproshops.com. I also have used a long cane pole and 12lb test monofilament line with a Kentucky Lake crappie rig attached.
