Billed as the oldest fishing tournament in the United States, the 2013 International Grand Isle Tarpon Rodeo takes place this weekend.

Angela Dorvin, event coordinator, said pre-registered participation is right on target for the event, which will run July 25-27 out of the Sand Dollar Marina. 

The official scales at the marina will close at 8 p.m. on Thursday and Friday, and at 6 p.m. on Saturday, Dorvin said. The pavilion, located next door, opens to the public each day at 11 a.m.

All registered participants are eligible to win the rodeo’s grand prize: a Blazer bay boat with a Mercury 150 Pro XS motor and a tandem-axle Magic Tilt trailer.

“The grand prize will be given away at the conclusion of the awards presentation Saturday night,” she said.

Anglers can register on-site, and can participate in the Big Game Division, Shoreline Division or Inside Division.
