National NatureServe Conservation Status
Rounded National Status Rank: NNR - Unranked
NatureServe Conservation Status
Rounded Global Status Rank: G3 - Vulnerable
Reasons: This species occurs from Point Conception, California to Bahia de Tortuga, Baja California in Mexico (USFWS, 2006), but is in serious decline due to overfishing.
Global Short Term Trend: Decline of 10-30%
Comments: Survey data from 1991 to 2001 from one region of the fishery showed a dramatic decline in density (28%) and the current condition of the abalone stock is an example of an uncontrolled fishery (Morales-Bojorquez et al., 2008).
Global Long Term Trend: Decline of 30-50%
Comments: Of the 7 abalone species distributed along the west coast of the Baja California peninsula, Haliotis fulgens and Haliotis corrugata comprise approximately 98% of the total fishery landings (Morales-Bojorquez et al., 2008).

The shell is thick and characterized by strong corrugations and is more circular than other American abalones. The two to four open respiratory apertures have edges that are strongly elevated above the surface of the shell. These holes collectively make up the selenizone, which forms as the shell grows. The epipodium is a “ruffle” of tissue along the side of the foot. The head and epipodial tentacles are black, but the epipodial fringes are a mottled black and white, with many tubercles on the surface and a lacy edge.
Pink abalone have separate sexes and broadcast spawn from March to November. Maturity is reached at about 1.4 in (35 mm) length or three to four years. Lifespan is 30 years or more.
Pink abalones are subject to a chronic, progressive and lethal disease: the Withering Syndrome or abalone wasting disease, leading to mass mortality.
Threats and conservation
Pink abalone are threatened by historic overharvesting, illegal harvest, withering abalone syndrome disease, and climate change. In 1996, the California Department of Fish and Game closed the commercial and recreational abalone fisheries in California, but populations continued to decline. California has a Abalone Recovery Management Plan to guide conservation efforts.
The pink abalone is a US National Marine Fisheries Service Species of Concern. Species of Concern are those species about which the National Oceanic and Atmospheric Administration, National Marine Fisheries Service has some concerns regarding status and threats, but for which insufficient information is available to indicate a need to list the species under the US Endangered Species Act.
Information regarding the status of pink abalone in Mexico is scant. A commercial fishery for pink abalone is still in place in Mexico and is managed by local cooperatives.
