Small-scale hatcheries

Abalone and multi-species marine fish hatchery

SEAFDEC/AQD opened a backyard-scale, abalone and multi-species marine fish hatchery in July 2009 to demonstrate profitable operations of abalone and marine fish requiring minimal investment.

The area:

•   measures 896 m2, situated beside AQD’s FishWorld museum

•   with gravel bedding and  perimeter fence made of bamboo posts and hogwire

•   each area (marine fish and abalone) has its own independent pre-filtered seawater supply system (with 2 HP centrifugal pumps and 1 HP roots blower for aeration)

•   concrete drain pits and main canal for harvesting and drainage for each hatchery area

•   backyard hatchery has common harvest and work areas, store room, equipment room, and roof structure
