January 15, 2007 - TeekaTan Phase 3 tests using a shark repellent and sunscreen combination have commenced. A new pen was setup this week, and the three resident juvenile lemon sharks have already completed two conditioning trials.

January 02, 2007 - Teeka Tan (OTCBB: TKAT) has announced that it has completed Phase 2 trials on a shark repellent sunscreen formulation. These trials were conducted at the Bimini Biological Field Station, South Bimini, Bahamas, using conditioned sharks. Sharks showed a preference towards baits that were not treated with a repellent/sunscreen formulation. Phase 3 trials are set to begin this month and will focus on obtaining more replicates for statistical significance, and improving cosmetics of the formulation.

December 08, 2006 - SharkDefense is on location at the BBFS with a film crew from LOOKS Filmproduktionen GmbH. Patrick and Craig from SharkDefense will be demonstrating magnetic and chemical repellent experiments.

October 23, 2006 - A series of repellent tests involving Cow-Nosed Rays (R. bonasus) has been completed! Working  with Bob Fisher at VIMS, blue crabs, a common prey item, were protected from captive cow-rosed rays using magnetic and metal alloy repellents. More trials will be conducted in late Spring of 2007 when the rays return to the Chesapeake area.

October 15, 2006 - Preliminary data suggests that a chemical stingray repellent is effective. In two trials with two female Dasyatis americana, these stingrays were repelled from conch bait cages with a 150mL dose of semiochemical. Trials will continue using cow-nosed rays later this month. 

October 13, 2006 - A method of implanting chemical repellent gel directly into whole squid is undergoing evaluation at South Bimini. This method will allow fishermen to simply bait the hook with the pretreated squid, eliminating additional preparation time during a longline set. These baits are undergoing two 24-hour trials at South Bimini, Bahamas this week. 

Septebmer 12, 2006 - Eric is off to the NMFS Sea Turtle and Pelagics Sensory Biology Meeting at the Virginia Institute of Marine Science, Wacheapreague, VA. There will be presentations and discussions on methods of reducing sea turtle and shark bycatch, and SharkDefense will be presenting updates on magnetic and metal alloy work.

August 04, 2006 - SharkDefense was featured in two segments on Discovery Channel's Shark Week 2006: Dirty Jobs: Jobs That Bite, and Everything You Need to Know About Sharks. Sincere thanks to Mike Rowe, Pilgrim Films & TV North, and the Creative Differences crews.

Two SharkDefense experimental devices were featured: Our water-activated repellent grenade, and the can-launcher from MARSARS , which launches our repellent grenades from shore.

July 12, 2006 - We are heading off to the 2006 Joint Meeting of Ichthyologists and Herpetologists in New Orleans, LA. Many colleagues from the BBFS, including SharkDefense, will be presenting their shark-related research abstracts, papers, and posters this year. SharkDefense will be discussing the use of chemical and magnetic sharks repellents on demersal longlines.

June 26, 2006 - Teeka Tan (OTCBB: TKAT) has announced that it has completed Phase 1 trials on a shark repellent sunscreen formulation. These trials were conducted at the Bimini Biological Field Station, South Bimini, Bahamas, using a specially-formulated repellent fragrance from SharkDefense that is allowable for cosmetic use (SCC: 96/335/EEC, EU: 1996). A more strigent series of Phase 2 trials will begin in July.

June 24, 2006 - We have been evaluating a class of non-magnetic metals that induce aversion in juvenile lemon sharks and nurse sharks. We cannot detect any magnetic field (to 0.1 mG) or electrical current (to 100nA) produced by these metals in seawater, but the sharks can! We call it "Mystery Metal". Stay tuned for more updates at Ocean

May 25, 2006 - It is with sorrow that we report the passing of Nelson "Hammer" Beideman of Blue Water Fishermen's Association and Integrated Marine Research.  Nelson was a highly respected colleague  and personally helped SharkDefense in our research. Requiescat in pace.

September 15, 2005 - Two natural shark repellent compounds were successfully tested using the tonic immobility protocol on lemon sharks and nurse sharks. One compound is water soluble, and both pose no significant odors. The low price and availability of these compounds is very exciting. The compounds will be scaled up and evaluated on larger shark populations for February 2006. Stay tuned!
