This weekend ...
* Show time: The first of the lengthy late winter and early spring outdoor shows starts tomorrow with the opening of the three-day 15th annual Chesapeake Sportfishing Show at the Annapolis Armory. Limitations in the size of the armory is the only thing that holds this exceptionally popular show down. It's primarily a fishing show, targeting bay and ocean angling, with a sprinkling of the freshwater sport added. Boats, archery and hunting play a minor role, though there will be archery demonstrations. In addition to many booths featuring professional anglers and the latest in tackle there will be continuous fishing movies and seminars conducted by charter skippers and guides.
The seminar Trolling for Trophy Rockfish in May will start things off tomorrow at 7 p.m. At 8 it will be Bass Fishing In Maryland, and at 9, Fishing for Rock at the Bay Bridge.
The remaining seminar schedule: Saturday: 11 a.m., Rockfishing the Bay Bridge; noon, Bass Fishing In Maryland; 1 p.m., Upper Chesapeake Fishing Possibilities; 2 p.m., Trolling for Rock in May; 3 p.m., Mid-Atlantic Offshore Possibilities; 4 p.m., Rockfishing at the Bay Bridge; 6:30 p.m., Bass Fishing In Maryland.

Names and places ...
* Maryland's wild turkey population continues to improve. DNR statistics indicate last year's hatch averaged six poults for each adult hen, and that's quite a hatch. In the fall kill, 72 percent were young of the year. Also, more than half of the bag occurred on private land.
Josh Sandt, who heads DNR's Wildlife Division, reports preliminary thinking for 1994 could involve opening spring turkey seasons in Carroll, Wicomico, Caroline, Kent, more of Queen Anne's, and part of Cecil. Turkey management is proving so successful that the DNR plans to stock only about 250 more wild turkeys in the state, then give up the practice and let the birds finish the job. Every county except Prince George's now have wild turkeys, and plans are under way to fill that void.
* Any hopes that hickory shad would be legally catchable this year are --ed in DNR regulations this year that prohibits the catch, keeping and possession of any hickory (or its roe) caught originating in Maryland.
* Maryland isn't the only state stocking hatchery-reared wild rockfish. Virginia has released 211,000 stripers of 3 to 10 inches in length in the Mattaponi and Pamunkey rivers of the Chesapeake complex. All have been tagged.
