Aquarium suitability awaiting assessment
Aquarium suitability has not yet been established for this record. Available observations do not constitute an acquisition recommendation.
The existing assessment does not establish aquarium suitability. Eligibility is reviewed separately before care completion is counted.
Haliotis sorenseni is a U.S.-listed endangered species. This profile is conservation-only and does not authorize possession, collection, or private husbandry. Evidence review: This remains a conservation profile rather than a livestock recommendation. Captive breeding by a recovery programme does not establish suitability for private aquariums. United States protection information is kept jurisdiction-specific, and institutional methods must not be converted into a casual aquarium recipe.
Research Evidence and Limits
These source findings support institutional assessment, identification or wildlife research. They are separate from aquarium-care completion.
Source findings and their limits
Offspring were grown for 17 months in 1,360-L tanks on microalgae. Four hatchery crops used diatoms on corrugated plates and were weaned to Macrocystis at 15–35 mm. Adult broodstock received Macrocystis and Palmaria in 15°C flow-through seawater.
Source limit: Documented professional hatchery stages and reproduction; the full permanent adult enclosure and maintenance protocol still references earlier methods rather than being completely specified here.
Sources: McCormick et al. (2016), white abalone culture experimentsAn eight-month juvenile trial used covered 1.3-L raceways, supplemental aeration and 0.2 L/min inflow. Alternating weekly Macrocystis and Palmaria were supplied with leftovers maintained. Growth was 41 versus 32 micrometres/day at the reported lower versus higher density.
Source limit: These are stage-specific working methods and comparative densities, not complete permanent physiological limits; reported biomass/volume conventions should be checked before reproducing stock calculations.

A deep rocky-reef abalone of the eastern Pacific represented here by a NOAA source record. Its documented range includes Eastern Pacific, Southern California, Baja California.
Feeding and Ecological Role
Grazes drift and attached algae on rocky substrate.
Conservation and Responsible Sourcing
Use current recovery and legal guidance from responsible authorities; historical imagery is not evidence of availability. Verify legal origin, collection method, and current trade requirements before acquisition.
Recovery through captive breeding
NOAA’s white-abalone programme combines surveys, captive breeding and outplanting to rebuild wild populations. Reproduction depends on animals being close enough for successful external fertilization; sparse remaining populations complicate recovery.
What this means for aquarium care
This remains a conservation profile rather than a livestock recommendation. Captive breeding by a recovery programme does not establish suitability for private aquariums. United States protection information is kept jurisdiction-specific, and institutional methods must not be converted into a casual aquarium recipe.
Evidence update and care limits
The researchers compared larval temperature treatments and juvenile algal diets, density and light. Larval and juvenile responses differed; juvenile growth and survival did not share one simple optimum. Higher tested temperatures were associated with mortality and withering syndrome. A study-specific growth maximum is not a lifelong safe range. MLL monitoring plan: Keep permitted conservation-culture records by stage, including algal identity, survival and health; do not transfer another abalone species' warm-water recipe.
A living record
Foundation profile reviewed against the World Register of Marine Species. Species-level media are bound only where the source record explicitly supports the taxon; unidentified abalone and sea-urchin records remain at genus or class level. Historical and superseded source names remain in provenance while the profile uses the accepted taxon. Public content last reviewed October 2, 2026.
