| 中文摘要: |
| Growth rates, measured as shell length and body weight daily growth, were studied in the eight families of Pacific abalone, Haliotis discus hannai Ino, reared at 12, 16 and 20℃ for 40 d respectively. The results show that J1Rh family grew the best at 12℃, with growth rates of (32.88±4.66) μm/d and (5.24±1.84) mg/d. C1Jm family had the highest growth rates of (58.00±2.00) μm/d and (9.71±1.21) mg/d at 16℃. J1Jm family ranked the first at 20℃, with growth rates of (66.00±1.76) μm/d and (10.99±0.34) mg/d.RjRh family had the slowest growth rates at all three temperatures. Shell length growth rates were 18.25, 33.00 and 43.13 μm/d respectively, while body weight growth rates were 2.47, 2.56 and 4.75 mg/d respectively. Both temperature and family had significant effect on growth rates (P<0.05). At 16 and 20℃, maternal effects on growth rates were not significant (P>0.05), but paternal effects on growth rates were significant (P<0.05). Results of this study indicate genetic difference among the families and importance of selecting male breeders in the commercial hatchery. |
