Field Specialist Dorien Schroder of Mossel Bay and six crew members had been chumming, an act of throwing food into the water to attract fish, since 0730 the morning of July 18 off Seal Island; Oceans Research has been conducting research for a population dynamics study in this area since 2008. Around 0830, after about 1 hour of chumming, there had been a fair amount of activity around the boat, taking data on at least four sharks, including an old friend known to the team as Pasella, which has been frequently spotted over the last three years.
However, the events of a casual day of collecting data was all about to change. Activity around the boat suddenly ceased and all was quiet for about five minutes. Schroder goes on to describe the following incident; Next thing I know I hear a splash and see a great white shark breach out of the water from the side of the boat hovering, literally, over the crew member who was chumming on the boat's portside. Schroder automatically sprang into action and pulled the crew member quickly away towards the stern of the boat's platform into safety. With all the crew members rushing to safety the 3m, 500kg shark landed in the boat on top of the fuel and bait storage containers. The shark landed only halfway in the boat and the team hoped that as the shark thrashed around that it would make its way back into the ocean. However, this was not the case and the shark proceeded to get itself stuck in between the 1.5 by 2 meter area behind the container and boat's stern. The shark, in a panic, began thrashing around, destroying equipment and even cut the fuel line.
Once back in the harbor, Cheetah moored next to a fishing boat and they assisted by giving the crew a water hose which was placed inside the mouth of the shark so that water could further ventilate the gills. The Smit Lombok then moored alongside Cheetah and they connected one of their large lifting hooks to the rope which was secured to the shark's tail and began to life the shark off of the boat and back into the water. The shark instantly began thrashing as soon as it hit the water and Johnson and Gennari quickly cut the ropes as the shark swam away from the stern. The shark was then seen swimming towards the harbor mouth.
The Oceans team had hoped that the shark would be able to orient itself out of the harbor, however, about 30 minutes after its release the shark beached itself onto a small beach inside the harbor. Gennari and Johnson returned to give aid to the shark in its orientation by physically trying to walk it, but the shark was unable to orient itself within the harbor and again proceeded towards the beach. The team of scientists then decided that they would have to safely lead the shark back out into open waters. The team fasten the shark to Lamnidae using two ropes attached to both the tail and behind the pectoral fins with the shark's head tilted upwards in order to ventilate the gills properly and slowly started making their way our of the harbor. Around one kilometer from the harbor the shark began to regain its orientation and strength and was cut lose, where it swam away with powerfully strides.
Thanks to the quick thinking of these scientists no one was injured and the shark survived to swim another day.
