October 19, 2007 - As we mentioned from Patrick Rice's longlining trip, we are still observing that one synthetic repellent is a bony fish attractant. A recent experiment shows
redfish (Sciaenops ocellatus) are attracted to baits dipped in the repellent. |

|
 |
August 31, 2007 - Special thanks to Claudia Steiner from Schweizer Fernsehen (Swiss TV) for producing the entertaining segment highlighting some of SharkDefense's research. A
video clip is in the Press Area of our website. |

- A welcome home and special thanks to Patrick Rice and the crew of the F/V Carol Ann. Patrick conducted numerous longline experiments with an experimental timerelease repellent gel incorporated into squid baits. Preliminary results show the gel is a swordfish and blackfin tuna attractant! Work remains to be done: SharkDefense needs to adjust the gel density and solubilities to keep more of the repellent in the squid at the very deep fishing depths.

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. |

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. |

- 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
