The Ceres Dolphins recreational swim club began its 50th year of competition last month.
"We've been around a long time," head coach Tracy Bull said. "We've produced a lot of good swimmers."
The Dolphins have a membership size of 130.
Swimmers range in age from 5-18.
"Our numbers are pretty solid," Bull said. "We have more boys this year. Our girls are still the backbone of our team."
Ceres' top swimmers are Zachary Jones (17-18 boys), Haley Fisicaro (17-18 girls), Colin Ramos (15-16 boys), Keana Miller (15-16 girls), Reuven Denton (13-14 boys), Julia Pata (13-14 girls), Agustin Leyva (11-12 boys), Hannah Denton (11-12 girls), Jacob Pfanenstiel (9-10 boys), Alyvea Olanolan (9-10 girls), Diego Armas (7-8 boys), Danika Brar (7-8 girls), Andrew Silveria (6&under boys) and Bianca Najera (6&under girls).
Jones and Fisicaro will also help coach.
Former Dolphin standout swimmer Montana Bull was named head assistant coach.
Jon Silveria will serve as the organization's new president.
The Dolphins opened the 2013 season with a fifth-place finish at the Tracy Invitational on May 26.
Ceres won its Mid-Valley Swim League head-to-head showdown versus Tracy, 9261/2-7231/2, on June 1.
The Dolphins have beaten the Tritons just twice in the last 45 years.
"We had even numbers going in," coach Bull said.
The Dolphins placed fourth at the Oakdale Invitational on June 8.
Ceres' remaining regular-season schedule features a mix of dual and tri meets, and invitationals.
The Dolphins will compete at the MVSL finals on July 20 at Sierra High School in Manteca.
"I expect us to win two to six High-Point trophies," Tracy Bull said.
Ceres swimmers practice five days a week, Monday through Friday, at Ceres High School.
Advanced members train three hours a day, with 90-minute sessions in both the mornings and evenings.
Intermediate/new swimmers spend one hour a day in the pool.
"It was extremely difficult to train the first month of the season because the water was so cold," coach Bull said. "They finally replaced the broken heater."
