The black abalone mollusk (Haliotis cracherodii) is a delicacy in many regions of the world, with fancy restaurant diners doling out as much as $40 per 6 to 8 ounce serving. To help solve the mollusk mystery, Yahoo News contacted Western Australia’s Department of Primary Industries and Regional Development (DPIRD). “The tag numbers are linked to records in our database that contain key information about each individual abalone,” Brown explained. “The tagging and release of tagged abalone has ceased, but the monitoring of the abalone will continue into the future,” Brown added. The DPIRD is now encouraging anyone in the area to report their own tagged abalone finds through an easy-to-use online portal.
