Abalone are a popular type of edible sea snail that have long been a delicacy in many parts of the world Their tender, slightly sweet meat and ornate shells make them a coveted ingredient However, abalone are very sensitive creatures and need special care to keep them alive outside of their natural ocean habitat.
In this beginner’s guide, you’ll learn everything you need to know about caring for live abalone, from handling and transporting them after collection, to keeping their tank clean and mimic their natural environment Follow these tips and your abalone will stay happy and healthy.
Why Keep Abalone Alive?
There are a few key reasons you may want to keep abalone alive rather than eating them immediately:
-
Better taste: Live abalone have much fresher, sweeter meat compared to frozen or canned. The flavor and texture noticeably declines once they die.
-
Watch them grow: It can be rewarding and fun to observe abalones grow over weeks or months in a home tank. Their iridescent shells develop more color as they mature.
-
Use for crafts: Abalone shells can be made into beautiful jewelry and decorations. You need the animal alive initially to remove the meat without damaging the shell.
-
Conservation: Harvesting wild abalone sustainably helps preserve dwindling populations. Keeping them alive temporarily eases fishing pressure.
Gathering Abalone and Transport
Before you can keep abalone, you first need to source some live specimens. Here are some tips:
-
Check regulations: Abalone fishing often requires a license and is limited to certain seasons and quantities. Be sure you are gathering them legally.
-
Find the right habitat: Abalone live on rocky reefs and prefer shallow, somewhat protected areas near abundant kelp. Search rocky crevices during low tides.
-
Use abalone iron: This special flat prying tool helps remove abalone from rocks without injuring their shell or body. Take care not to crack them.
-
Transport in seawater: Place abalone in a cooler or bucket filled with fresh seawater immediately after prying them off the rocks. Do not expose them to air.
-
Avoid extreme temperatures: Keep them sheltered from heat and direct sun when transporting. Drastic temperature swings can shock and kill abalone.
-
Get them into a tank quickly: Try to move wild abalone into your aquarium set up within 2-3 hours if possible. The longer they are in transit, the more stressed they may become.
Setting Up an Abalone Aquarium
Abalone are used to cold, nutrient-rich Pacific ocean waters. Replicating their natural environment in a home tank is crucial for their health and survival. Here are some best practices:
-
Large tank: A minimum 30-50 gallon tank is recommended for 1-5 abalone. This allows adequate oxygenation and dilution of waste products.
-
Chiller: Abalone thrive between 50-60°F. A water chiller is likely needed to maintain this, unless your room itself stays very cold.
-
Strong filtration: Canister filters that turnover at least 5-10 tank volumes per hour help remove waste and keep water clean.
-
Places to grip: Rocks and anchored kelp provide surfaces for abalone to cling to with their muscular foot.
-
Shallow water: Avoid filling the tank more than 12-18 inches deep. Abalone don’t swim and prefer shallow, rocky habitats.
-
Partial seawater: Use a mix of natural seawater and dechlorinated tap water. Seawater contains essential nutrients but can encourage bacterial growth if 100%.
-
Aeration: An air pump with airstone diffuses oxygen into the water, which abalone require. Breaking the surface also benefits gas exchange.
-
Cycling: Run the tank for 1-2 weeks before adding abalone to build up beneficial bacteria. Test for 0 ammonia, 0 nitrites, and <20 nitrates before adding them.
Caring for Abalone in Captivity
Once your abalone aquarium environment is fully prepped, it’s time introduce your live abalone. Ongoing care and tank maintenance will be required to keep them happy and healthy long-term. Here are the keys:
-
Feeding: Abalone graze on kelp and algae. Add marine plant supplements or rotate fresh kelp in the tank 1-2 times per week. Remove uneaten kelp promptly.
-
Water changes: Change out 10-15% of the tank water 1-2 times per week, especially if uneaten food accumulates. Use pre-mixed seawater if possible.
-
Testing water: Use test kits weekly to check ammonia, nitrites, nitrates, pH, salinity, and temperature. Adjust as needed.
-
Clean tank: Wipe down tank walls to remove algae buildup. Siphon the gravel to remove waste. Take care not to disturb the abalones’ grip.
-
Quarantine new abalone: Isolate and observe new abalone in a separate tank for 2-4 weeks before introducing them to your main tank.
-
Avoid stress: Limit sudden water chemistry changes, overcrowding, rough handling, or other sources of stress that could compromise their health.
-
Watch for disease: Look for sluggishness, loss of grip, odd odors or swollen/discolored tissue which may indicate a health problem requires treatment.
Abalone Handling and Anatomy
Abalone have fragile bodies that require very delicate handling. Here are some key points about their anatomy and how to handle them:
-
Shell: Made of mother-of-pearl, their shell protects their soft body and is easily cracked if handled roughly.
-
Respiratory pores: Located under the edge of the shell, these pores must remain submerged for them to breathe.
-
Foot muscle: The broad, muscular “foot” on their underside allows them to cling tightly to surfaces. Pulling them off forcefully can tear this muscle.
-
Mantle: The mantle lines the inside of their shell and secretes nacre to slowly enlarge their shell as they grow.
-
Head: Their head contains their mouth, eyes, and sensory tentacles. Avoid contacting the head when handling them.
-
Gills: Respiratory gills are located on the upper surface of their body under the shell. Damage to the gills can be fatal.
-
Lifting: Slide a hand under their shell between the foot and body to lift. Never pry up or pull directly on their shell or body.
-
Touching: Avoid handling them excessively. Touching their mantle or gills can interfere with their breathing.
-
Water exposure: Ensure respiratory pores stay underwater always. Even brief air exposure can fatally damage their gills.
Keeping Abalone Alive Out of Water
On occasion, you may need to keep abalone briefly out of water, such as during transport, tank cleaning, or processing for eating. Here are some tips for their survival:
-
Keep cool: Place them belly-up on ice or chill packs (about 40-50°F) to mimic ocean temperatures and slow their metabolism. Avoid direct contact with the ice.
-
Wrap in seaweed: Drape them with damp seaweed or cloth and mist occasionally to keep their gills moist.
-
Minimize time exposed: Try to process or transport them within 2 hours maximum if possible. Their survival time out of water is limited.
-
Shelter from sun: Keep them shaded at all times when out of tank. Sun exposure will severely overheat and dehydrate them.
-
Handle with extreme care: Their bodies become increasingly fragile when out of water, so be very gentle when lifting and moving them.
-
Watch for stress signs: Keep an eye out for gaping shells or mantle retraction as signs they are becoming overly stressed by exposure.
-
Return to water gently: Once ready to return to their tank, submerge them under water gradually rather than plunging them in to avoid shock.
Harvesting Abalone Humanely
If you do plan to eat your cultivated abalone, it is possible to harvest them humanely:
-
Cool down tank: Lower the water to 50°F for 1-2 hours before removing them. This slows metabolism and reduces stress reactions.
-
Rapid processing: Have ice/prep station ready so they can be swiftly processed after removal.
-
Cut muscles: Use shears to sever the main muscle anchoring their foot muscle before prying them off rocks. This prevents tissue tearing.
-
Spike quickly: Use an awl to instantly spike their nervous center behind the head before they can register pain. This causes rapid death.
-
Chill afterward: Place them belly-up on ice immediately to allow exsanguination and preserve meat quality.
-
Clean thoroughly: Take special care cleaning to avoid shell and tissue damage now that the protective muscle has been cut.

What Does Abalone Taste Like?
When properly tenderized, abalone has a taste often likened to a cross between scallops and foie gras. Abalone is crunchy and chewy, and it tastes salty from the ocean where it lives. It’s also sweet and rich, with a buttery finish. This food is also an excellent way to get a taste of umami as well.
How to Cook Abalone
To prepare abalone, it must be shucked, cleaned, and tenderized or the meat will have a rubbery texture. The abalone attaches to its shell with a solid round muscle at the bottom. To gently release the meat from the shell, a wide, flat, wooden spatula works well. It is sometimes soaked, blanched, or frozen prior to shelling. The viscera (guts), black edges, and tough outer skin is then removed. All of it can be eaten, but these trimmed pieces are hard to prepare and taste good, so people usually throw them away.
Once the abalone meat has been cleaned, it needs to be made tender. This can be done by pounding it whole or cutting it into thick steaks, or it can be cooked slowly for a long time. Seasonings should be kept light because the delicate meat will take on the taste of other foods it’s cooked with. Abalone is a delicate food that is often quickly and gently fried in a pan. It can also be steamed or poached. It is also eaten raw, particularly in Japanese sashimi.
