Just a reminder! On Thursday evening September 19th, the UH Sea Grant Hanauma Bay Education Program continues its public outreach series at the City and County of Honolulu’s Hanauma Bay Nature Preserve. Thursday September 19, Fish Anesthetics and Aquaponics? Investigation of `Auhuhu, A Traditional Fish Poison Plant Leina‘ala Bright, School of Hawaiian Knowledge, University of Hawai‘i and Danielle Hull, Oceanography-Marine Geochemistry, University of Hawai‘i In Old Hawai‘i, fish trapped in tidal pools at low tide were sometimes caught with mild toxins obtained from the ‘auhuhu bush, a legume known in many parts of the Pacific. The whole ‘auhuhu plant were crushed into bits, either with a mortar and pestle or with rocks found by the shore. The materials were then scattered in tide pools around the base of rocks and into holes where fish might hide. In a few minutes the small fish that were present would float to the surface and could be picked up. This effect did not last more than twenty or so minutes, depending on the size of the tide pool and the speed with which fresh seawater entered it and diluted the toxin. Any fish that were washed out of the pools or overlooked in the gathering would recover and swim away, since the toxins merely stupefied the fish rather than killing them outright. To learn more attend our program on Thursday evening. As always, these events begin at 6:30 p.m. on Thursday evening in the theater at the Hanauma Bay Education Center. Events are free and open to the public, with no charge for parking after 5:30 p.m. We hope to see you on Thursday evening! These programs are supported and funded by the City and County of Honolulu Department of Parks and Recreation.
