Shark Wranglers' try to regroup after death of Maya

The men of Shark Wranglers have a time limit for their mission in the waters off the coast of South Africa. Find, capture, tag and release 50 great white sharks for tracking and scientific study.

Shark Wranglers aired the third show of its debut season on History and the men of the shark research vessel MV OCEARCH were devastated after one of the great whites perished in the course of their operation.

It is a risk inherent in the mission which team leader Chris Fischer understands. He described the expedition like this.

"We don't know much. We don't know why they're here. We don't know where they go. We don't know where they breed, give birth and the only way to find out is to get these tags on them so that we can protect those areas where they are the most vulnerable."

Fischer's bio on the History channel website for Shark Wranglers indicates that he had a hand in developing the method to capture and tag the sharks that can weigh up to a ton. Humans can be better protected from shark attacks if the data gathered by the team successfully identifies their whereabouts.

In "The Curse of Maya" the team headed up by Chris Fischer was not only affected emotionally, the mission was put in jeopardy. The body of a dead shark will keep others away from the area and a decision had to be made.

Do the men try and recover the body of Maya to enable them to continue in Mossel Bay or do they move on? They have yet to successfully tag more than three sharks and have fallen behind in their 40 day mission with 47 sharks to go.

The decision was made to go down and try to retrieve Maya and the brave soul who volunteered was Ryan Johnson, the team's lead scientist who has worked with and studied the great white shark species for a decade.

There was no cage surrounding Johnson as he went to find the shark's body and he was given a limited amount of timeto be submerged before he would have to get out of harm's way. Despite the tag on Maya that revealed she was no more than 40 meters from the vessel, she was not found.

The greatest danger is attack from below a person and that means that as the diver resurfaces he is in the most peril. Ryan was retrieved quickly and the team was forced to try and make up the time lost.

They found two others and the capture process is complex. Not only do they need the shark to bite the chum on the line but they must muscle it into a wooden lift that projects from the side of the ship.

Rough seas make the lift vulnerable to cracking because it is exposed on three sides in the water. Wrangling the shark to get it into the lift is quite a chore. Once it is done, team members leap into the lift as the shark lies on the wooden surface.

Keeping the shark alive and as calm as possible is the key to a successful operation, as they implant the device that has a GPS signal on it. With a stop watch ticking, team members perform the necessary mini-surgery..

The crew is vulnerable throughout the time the shark is captured prior to its release, making the action on Shark Wranglers real and exciting. Learn more about the team members and their mission at the Shark Wranglers website, here.
