From 2008 to 2010,the artificial propagation and embryonic development observation of Barbus capito were conducted,alkaline-and saline-adapted ability of embryos and larvae were evaluated.The results show that B.capito lays pelagic eggs and reproductive cycle spans a whole year.At the temperature of 19-23 ℃,the response time of induced spawning drug was 21-26 h.The fecundity of the females(1.4-2.3 kg)was about 8×10⁵-1.4×10⁶ eggs.The induced spawning rate,fertilization rate and hatching rate were 63.9%,81.5% and 86.6%,respectively.The eggs of B.capito were offwhite and the maximum egg diameter was 4.5 mm after absorbing water.At temperature of 20-23 ℃ the accumulated temperature was 49.82 ℃·d from fertilization to the hatchingout larva,and 125.14 ℃·d to the floating-up larva.The length of larva,just hatching out,was(6.07±0.18) mm,and the length of larva,just floating-up,was(8.30±0.47) mm.The saline-alkali tolerant experiment showed that there was no impact on survival rate of embryos(72 h)when salinity was below 3.2 and alkalinity was below 14.32 mmol/L,and there was no impact on survival rate of larvae(96 h)when salinity and alkalinity was below 5.1 and 14.32 mmol/L respectively.
