Spontaneous spawning of wild-caught abalone in the hatchery was achieved in 1994.
The following year, SEAFDEC/AQD started producing abalone juveniles in its hatcheries,
and because the effort was pioneering, production was no higher that 50
million until 2005 when this skyrocketed to 198 million.
The breakthroughs in abalone R&D at AQD had
come rapidly, noted as follows:
1996 - Grow-out in floating sea cages
was successfully undertaken
1997 - Abalone life cycle was
completed
1998 - Formulated diets for juveniles
were developed, and grow-out rearing in tanks successfully achieved
1999 - Formulated diet for broodstock
maturation and spawning was successfully tested
2000-2001 - Seed production underwent
more refinement, shell-marking method by feeding formulated diet was
developed, and mass production of juveniles for culture and stock
enhancement was started
2002-2003 - Searanching and stock
enhancement begun experimentally, and techniques in abalone grow-out
in floating net cage were refined
2004-2005 - Hatchery techniques for
the mass production of juveniles were developed, behavioral studies
of hatchery-produced juveniles for stock enhancement were conducted,
and AQD began a training course on abalone hatchery and grow-out
2006 - Abalone hatchery technology was
pilot-tested in a private hatchery in Oton, Iloilo |
