The Bardi Ardyaloon hatchery has successfully produced Trochus shell at One Arm Point for a number of years, including reseeding the reef surrounding the area.
Manufacturing activity is modest, consisting mainly of a garment factory in Yap and production of buttons from trochus shells.
At Scott Reef, on 25 May, Gayundah boarded and detained two Dutch schooners with illegal catches of trepang (sea cucumber) and trochus shell, and escorted them into Broome on 29 May.
