BLUEFIN TUNA: BAHAMAS: Bimini white marlin anglers were flabbergasted last week to find several schools of giant bluefin pushing northward a full month ahead of schedule. Confusion was so rife that only one fish was boated. The unperturbed sportsman was Harry G. Rieger Jr. of Philadelphia, who outlasted a 479-pounder in a two-hour-and-55-minute tussle on 24-thread.

TROUT: PENNSYLVANIA: SO April 15 and, though streams are now bank full and M after recent storms, agent reports they will clear for opener. He also reports that First Fork of Sinnemahoning, Driftwood Branch and Kettle Creek are heavily stocked with brook trout and some top 17 inches.

The fish commission has just delighted fly practitioners by releasing a list of 15 streams totaling 52 miles of water on which fly-fishing only will be permitted. Spoons, spinners and plugs are ruled out, the areas may be fished only from 5 a.m. to 9 p.m., the creel limit is six trout and the minimum size nine inches. The water: Cove, Hickory Run, Sand Spring Run, Mud Run, Trout Run, Young Woman's, Dunbar and tributaries, Falling Springs, Little Lehigh, Big Bushkill, Cross Fork, North Sandy, Muddy, Yellow and Manatawney creeks.

MINNESOTA: FF only on 23 chilly north-shore streams now open with lethargic browns and brooks eying bait and spinning lures with almost unanimous disinterest. Grand Marais area is just thawing but OG as spring progresses.

BRITISH COLUMBIA: Lower mainland sloughs unreliable, but Harrison River cutthroat are taking flies. On Vancouver Island fly anglers are also finding cooperative trout at the mouths of the Little Qualicum, Oyster and Campbell rivers; OVG all along the coast.

WISCONSIN: Brule C and open between Highway 2 and Lake Superior, but the best of early fishing has been between Highway 2 and County Highway (FF), where a heavy run of spawning rainbows and some browns are reacting to bait. Few fly-fishermen in evidence, but OG as WT rises.

CHANNEL BASS: NORTH CAROLINA: FVG now in Hatteras Inlet. Last week Fred Edwards of Virginia Beach casting squid from Edgar Styron's cruiser Twins IJ quelled a 49-pounder which local spy insists is one pound larger than any channel bass caught in 1956. So far surf casters have been shut out but OG.

BONEFISH: FLORIDA: Upper Keys guides advise FVG with last week's star angler ex-President Herbert Hoover. Wielding a standard casting rod and 18-pound test line, Mr. Hoover in three days landed three out-sized bonefish of 11, 10½ and 9½ pounds; OVG.
