The Status and decline of pinto abalone in Washington State
The Washington Department of Fish and Wildlife (WDFW) regularly monitors the abundance of pinto abalone (Haliotis kamtschatkana kamtschatkana) at index stations throughout the San Juan Archipelago (SJA) and between 1992 and 2006, the abundance of these charismatic invertebrates declined by 77% at these index stations. Furthermore, the average shell length of the surviving animals has increased. This suggests that not only are fewer abalone surviving, but fewer of the survivors are the young abalone that will be necessary to perpetuate future generations of pinto abalone.
