San Juan Island’s Justin Nibler reeled in the biggest catch of Week 4 to shake up the leader board of the Frank Wilson Memorial Derby.

Nibler’s Week 4 winner, at 13.63 pounds, wasn’t hefty enough to bump Brenda Schmidt from the lead, but its weight proved large enough to claim the $75 weekly gift certificate from derby sponsor King’s Marine, and catapulted Nibler into second place, with six weeks remaining in the annual 10-week fishing competition.

Also in Week 4, Don Wilson landed a 12.62-pounder to take over third place and Joe Crisanti moved into fourth place with a 11.92-pound catch.

Named in honor of the late Frank Wilson, a former chief of San Juan Emergency Medical Services, the annual winter’s end fishing tournament is part charitable, with proceeds benefitting San Juan EMS.

In addition to weekly prizes for biggest fish of the week, the derby features a $1,000 grand prize for the biggest fish hooked, landed and weighed-in over the course of the 10-week long tournament. Derby weigh-in is 9 a.m. to 5 p.m. at King’s Meat Department.

Entry fee is $50, contact King’s Marine, (360) 378-4953, for entry information.
