GALVESTON, TX (KTRK) -- Thousands of families are visiting Galveston Island for spring break, and some of them were in for a big surprise.A couple of fisherman in a boat caught a shark, measured it and released it a few blocks west of 61st Street.A Houston mom visiting Galveston with her son captured the incident on video with her cell phone Wednesday. We showed families at the beach."Surprising. You have to be careful and don't go all the way outside." Her grandfather Bruce Ishem said, "They were asking if there were sharks here, they are from Oklahoma," little girl Jaiden Hill said.It's something many families say they've thought about before. The beach patrol says it's not unusual."It's very concerning, yes ma'am. We didn't get in the water this trip because we didn't bring bathing suits down. I think next time we might be a little more careful," mother Amy Mouton, of Cypress, said.Galveston Island Beach Patrol Chief Peter Davis says an actual bite is very rare in Galveston noting."There are sharks in the Gulf," Davis said. "Anytime you're in the water you want to shuffle your feet unless you're in a big hurry. That sends a vibration that lets baby fish, catfish, stingray all the stuff you don't want to mix with, they'll get out of your way if they know you're there," said Davis.The fishermen measured the shark and then threw it back into the water to cheers. It is exactly the advice of one of the youngest beachgoers we talked too."I would let it be back in because I'm an animal lover, and I don't want it to die and it would bite me," little Adelei Mouton said.
