Abstract
In the present study, intraspecific crossing experiments between Chinese (H) and Thai
populations (T) of Babylonia areolata were conducted by using a complete diallel design (H, T,
TH, and HT). A total of 45 pedigreed families were obtained and cultured under the same
environmental conditions. Positive heterosis was observed for many developmental parameters
and shell sizes for most stages from juvenile to adult. Hatching and metamorphosis occurred
significantly earlier in the hybrid (HT) than in the parent groups and a crossed group (TH). Rate
of metamorphosis was also higher in HT than in the other three groups. Heterosis in shell length
and body weight of the crossed group (HT) from the nursery and grow‐out stage to harvest time
was high and significantly different from the H, T, and TH groups. For mortality rate from
juvenile to adult, total and average heterosis of the crossed group (TH) was positive and
significantly different from H, T, and HT. The results of the present study show that intraspecies
crosses can be a potentially useful way to increase the economic traits for B. areolata and thus
provide a promising method for genetic improvement of the species as a new aquaculture stock
in southern China.
