The state Wildlife Board voted Friday to do away with winter restrictions limiting the number of fish Utahns can pull out of the state's northern and central lakes and streams.

"There still will be winter daily limits of four trout on less than a dozen lakes," said board spokeswoman Kathy Quinn. "But the limit will be eight trout 12 months a year on most areas statewide."However, the proclamation lifting the winter rules will not become effective until Jan. 1, 1989, the board said. Winter restrictions remain in effect through the rest of this year for northern and central Utah waters.

The few areas where the daily limit will remain at four trout from November through May include East Canyon and Lost Creek reservoirs.

"The idea of the change was to open up more winter fishing opportunities for Utah's approximately 600,000 fishermen," said Quinn.

The board also issued some size and catch limits for bass on Deer Creek and Rockport reservoirs.

Bass 12 inches in length or shorter must be thrown back, Quinn said. And the daily bass limit on Deer Creek is six fish, and on Rockport the limit is two bass.

The panel considered several other fishing proclamation changes, including reducing the number of hooks allowed on so-called set lines. It reduced the number from 30 hooks to 15. And the board required set-line fishermen to buy a $10 permit, in addition to the regular $18 annual fishing license for adults.

The board expanded spearfishing for scuba and snorkel divers to Flaming Gorge Reservoir, but said game fish can be taken only between June 1, 1989, and Sept. 5, 1989, while it continues to study the issue.

Spearfishing now is allowed only in Deer Creek Reservoir, Fish Lake and Steinaker Reservoir. And fishermen must obtain a free permit.

In addition, the board placed a 30-inch limit on all Tiger Muskie Pike caught in Pineview Reservoir.

The sterile variety of muskie were planted in the northern Utah lake earlier this year, primarily to control non-game fish, said Quinn, adding "it will be several years before any will be 30 inches long."
