World abalone production;
treat and opportunity
economically important
marine gastropod
demand moderate to high
price
popular among Asian
cuisines
World-wide distribution in tropical and
temperate waters of both hemispheres

FROM CAPTURE TO CULTURE
Ten year comparison: capture &cultured fisheries
(Gordon & Cook, 2001)
World abalone production; treat and opportunity (continued)
During the same 10 year period, while the abalone captured
fisheries declined 30%, cultured abalone production increased
over 600%!
However, still approx. 5,000 mt short in supply by 2005
Support increasing important role of abalone
production from aquaculture.
Abalone in Thailand and its potential
Former works reviewed by Jarayabhand and
Paphavasit, 1996 (Aquaculture 140; p.159-168)
concluded that;
3 species of tropical abalone i.e. H. asinina, H. ovina,
and H. varia (H. asinina and H. ovina have potential)
H. asinina
H. ovina
H. varia
Among abalone found in Thai waters, Haliotis asinina
demonstrates the highest potential for commercial
cultivation compared to H. ovina and H. varia.
Due to high growth rate, ease of spawning, and high
meat yield offer excellent potential f
