We live in a world of numbers, and when it comes to fishing, it's no different. ¶ We fish with 8-pound test line, measure the length of fish to determine if we can keep them and count dollars for licenses, minnows and jigs. ¶ We measure water temperature, check water depth and plug in GPS coordinates for favorite fishing holes. And, of course, we count fish. Especially if I catch more than you. ¶ Saturday, 500,000 people — one-third of the state's 1.5 million anglers — are expected to wet a line on the fishing opener. (What will those other 1 million anglers be doing Saturday?) ¶ Here are some fishing-related numbers you can count on:
