Use of Chemical Materials as Shark Repellants
Abstract
The development of a material designed for the protection of personnel from attack by sharks is described. Results are given of the Laboratory development and field tests. The effectiveness of several substances in protecting baits has been demonstrated by field testing under various conditions. A dark demonstrated by field testing under various conditions. A dark water-soluble dyestuff has been shown to be particularly effective as a repellent material against sharks under normal fishing conditions both in daylight and at night and against excited sharks on the surface. A unit of the repellent material consisting of 80 percent dye with 20 percent of copper acetate for which repellent qualities have been also demonstrated is described. The unit is designed in a readily available form for the individual user. Tentative specifications for the procurement of tall materials are given.
