摘要
采用新的性腺发育控制技术和温控转换受精技术,对皱纹盘鲍与黑足鲍进行了杂交和自交育苗比较研究。结果表明,皱纹盘鲍♀×黑足鲍♂的杂交受精率和孵化率分别为23.4%和32.87%,皱纹盘鲍自交受精率和孵化率分别为77.97%和76.86%,二者附着率和变态率相近;在水温20℃,盐度3.0%的条件下,杂交鲍胚胎发育速度明显比自交鲍滞后,但生长速度明显高于皱纹盘鲍,体现出较好的杂交优势。
With the new technology of abalone gonad development control and temperature reversion control for the fertilization,the gametic hybridization breeding between H.discus hannai and H.iris were studied.The results showed that the fertilization rate and larval hatching rate of hybridized breeding between H.discus hannai ♀ and H.iris♂ were 23.4% and 32.87% respectively,while the fertilization rate and larval hatching rate of H.dis cus hannai autocopution were 77.97% and 76.86% respectively,the attachment rate and the metamorphosis rate between H.discus hannai and the hybridized abalone were similiar.The procedure of embryo development of hybrids was lagged than pure progenies when the temperature was at 20 ℃ and salinity was 30,but the growth rate of the juvenile hybridized abalone was significantly higher than H.discus hannai.F1generation of the hybridization indicated better production performance and heterosis.
