Abalone life cycle
​By adjusting the temperature of the water over a period of time you can condition male and female abalone to be ready to reproduce. Abalone are broadcast spawners (see cool video link to yumbah abalone spawn) and their eggs are demersal which means they are heavier than water. When eggs are fertilised it takes about 18-24 hours at about 18 degrees, they hatch into a trochophore.

After about 20 hours the trochophore develops into a Veliger larvae at a similar temperature. During this time they are feeding on a their own egg yolk supplies. After about 6 or more days once they have found a suitable habitat to settle (in a hatchery situation the correct substrate and algae is ideal), they transform into a post larvae. These post larvae feed on diatom cells on large plates in the water until they reach a certain size and then are moved into raceways or grow out tanks.
​
Different Hatcheries and science have developed different feeding regimes until the abalone reach specific marketable sizes. As with all aquaculture it is important to have excellent water quality.

How to prepare
  1. The abalone is stuck to its shell by a small muscle about the size of a 50 cent piece.
  2. Hold the shell firmly in the palm of one hand, do not move this hand.
  3. With a sharp knife cut the abalone from the shell, cutting as close to the shell as possible so you don’t lose any meat..
  4. The guts can then be cut out and discarded and the lip removed if desired. While the lip is a little tougher than the rest of the meat, it is still delicious.

  • Abalone is farmed in regional seafood communities; Dunalley, Bicheno, Clarence Point and Stanley.
  • ​Farmed abalone can live up to forty years, they are sold when they are around 3 years old 
  • Tasmanian farmed abalone injects an estimated $3.7 million into communities.
  • A female abalone produces one and a half million  eggs in each spawn.
  • Holes in the abalone are called respiratory pores where seawater, sperm, eggs, faeces and urine is excreted.
  • Males gonads are cream to white and females gonads are green, brown or maroon​
