The 1.41-2.87-year aged parent small abalone from the 7 family of 5 geographical populations (Keelung, Tatung, Tainan, Kaohsiung and Penghu) was selected for artificial propagation. Nine experiments were conducted, three family juveniles were successfully produced from hybridization, and all post-larvae from the same family parents died before grew up to be the fry. The hybrid young small abalone acclimatized higher water temperature (32 ℃) and lower salinity (15 psu), the survival during the juveniles period, from leaving the plastic plates to the size not dropping outside the cultured box, reached 60 %, and was 97% in 20 weeks cultured in the boxes. The growth and survival of two family young abalone cultured at the same density in each FRP tank combined in a water recirculated system were compared. The Keelung K1 family grew faster but survived lower contrast to the Tainan-Keelung family. Although the average shell length, width and weight of abalone varied a little at the nearly same age, 232 dph and 243 dph respectively. Besides, the hybrid fry from the Taiwan-Japan and Taiwan family and 6 Taiwan family were produced; they were cultivated in the good environmental and feed with quality food to become the selected family for good performance of growth and reproduction.
