Our scientists used the semiochemicals in our product to reduce shark by-catch by 71% in a government grant initiative.
- Scientists estimated that if our semiochemicals are applied globally then 4,258,080 – 8,279,600 sharks a year will be saved.
- The world wide environmental impact potential is highlighted in this infograph
- An Agency under the U.S. Department of Commerce released these findings in a report to Congress: NOAA Study Findings
Verified field testing on numerous shark species.
- 15 species have proven to be effectively repelled by the semiochemicals in SharkTec’s product.
- Reported by: C&E Article
- Reported by: National Geographic
- University of Miami oversaw study.
- A 5 year field trial on SharkTec’s technology proved to repel 2 species of sharks 100% of the time within 1 minute of local dispersion of our product.
- The findings were published in the scientific journal Ocean & Coastal Management.
- Seton Hall University contributed to the study.
- Published Findings: Ocean & Coastal Management Journal
- A study concluded chemical signals travel much further than mechanical or electrical signals.
- Olfaction is considered especially important as a distant sense because chemical signals can become entrained in currents and transported much farther in the marine environment than mechanical or electrical signals (Hueter et al., 2004).

Shark species are chemically aware of its dead and will avoid odors that replicate this awareness.

Semiochemicals found in the bodily secretions of predators may convey survival information to a shark and elicit rapid flight from an area that is potentially dangerous.

The findings from this study suggested that sharks may be chemically aware of the presence of potential danger through the sensing of bodily secretions from predators.
