RESEARCH
MISSION
Sharks are key to maintaining a balanced and healthy marine ecosystem. Unfortunately, the knowledge gap on the population status and distribution of shark species is hampering the implementation of effective conservation measures and policies.
Founded by marine conservationists and scientists, the SharkSafe Barrier™ company is true to its core value of preserving the marine environment and protecting sharks and it is fully committed to assisting and endorsing established research institutions, working to collect and publish scientific data needed to improve shark conservation globally.
OVERVIEW
RESEARCH ON THE
SHARKSAFE BARRIER™
The SharkSafe Barrier™ scientific testing was developed in three phases:
01 Magnets as shark deterrents
02 Visual and magnetic barrier deterrents
03 Exclusion capability of the barrier
All the phases of this study demonstrated that the SharkSafe Barrier™ successfully manipulated the swimming patterns of all interacting sharks and were published in peer-reviewed scientific journals.
We deployed prototypes in South Africa and The Bahamas, attracted the sharks with chum to motivate them to go through it and observed that none of them (84 white sharks and 41 bull sharks) swam through the barrier. By installing the SharkSafe Barrier™ around a beach, beachgoers will be protected and the marine life will not be harmed.
With the exclusion tests in South Africa and The Bahamas we could prove that SharkSafe Barrier™ can effectively keep sharks away from a food source. This was the last step of the scientific tests to prove that SharkSafe Barrier™ can effectively protect a swimming area, by keeping sharks separated from people.

SCIENTIFIC PUBLICATIONS
The SharkSafe Barrier™ is the only eco-friendly alternative to anti-shark nets that has been scientifically tested. The different tests spanning from 2011 to 2016 have been published in the following peer reviewed articles:

UPCOMING
FUTURE PROJECTS
- Environmental impact studies aimed at improving the design of the permanent anchorage system, for enhancing biomass growth.
- Independent study in collaboration with the Reunion Shark Security Centre on the exclusion of bull sharks in New Caledonia.
- Engineering research to adapt the technology to be installed on more coastlines and sea substrates.

CURRENT PROJECTS
WHAT WE ARE WORKING ON NOW
SharkSafe Barrier™ Pty is supporting Stellenbosch University Shark Conservation Action Plan, with a strong focus on the collection of field data, to monitor the status of shark populations in South Africa and the training and supervision of aspiring marine scientists, to ultimately guide conservation policies by publishing the research results in peer-reviewed scientific journals.
