Abstract
The field practice was conducted at Bureau of Fisheries and Aquatic Resources Regional Mariculture Technology Center (RMATDEC at Brgy. Lucap Alaminos City, Pangasinan, from June 13, 2016 to July 22, 2016. The aim of the farm is to maintain one thousand broodstock and produce fifty eight thousand quality juveniles for technology demonstration and stock enhancement.
The activities involved in hatchery production of Abalone (Haliotis asinina) are cleaning of tanks, conditioning of abalone, selecting of breeders, spontaneous spawning of breeders, egg collection and incubation, veliger and egg stocking in settlement tank, feeding of abalone, culture of benthic diatom (amphora sp. and Navicula sp.), daily monitoring of water quality parameters.
The strengths of the hatchery are good security, production of natural food and power supply while weaknesses of the hatchery are lack of technical knowledge of laborers and lack equipment for water quality monitoring.
