The abalone geographical populations from Keelung, Tatung, Tainan, Kaohsiung and Penghu were reared at this research center and their F1 or F2 generations were selected to compare their growth and survival. The survival rate ranged among 55-87% when the 5 population cultured indoor in 35 weeks, higher survival were found in Tatung and Penghu strains, and the lowest in Tainan strain. While the lower survival rate were found in two hybrids, Keelung X Tainan and Tatung X Tainan, 55% and 38% respectively cultured outdoor during January to April. Shell weight ranged among 2.72~23.92g with average of 6.94-9.90g, while shell length ranged 2.77~5.50cm (average 3.40~4.72cm) when the abalone reached 1.04~1.28 year old. A big variation found in each strain and both the largest length and weight were observed in the Tainan strains.
