다국어 초록 (Multilingual Abstract)

Morphometric traits, percent shell weight, percent cavity volume and condition index of 4-year-old induced hybrid abalone from female Haliotis gigantea Gmelin and male Haliotis discus discus Reeve were compared to those of the parental species. Apex height/shell height of the induced hybrid abalone was in between the average height of the parental species. The induced hybrid abalone shared three traits with the paternal species and two with the maternal species. After 4 years of growth, the condition index of the induced hybrids weresignificantly higher than that of either parental species ( P< 0.05). Generally, induced hybrid abalone displayed an external morphology that was intermediate between the representative of both parental species. Haliotis gigantea and the induced hybrids had four respiratory pores, while H. discus discus had five.
