利用从日本引进的大鲍,与我国产皱纹盘鲍进行了杂交育苗试验。在 540 m2鲍育苗地中,1999年 6月常温采苗至当年 11月份,培育出平均壳长 17.9 mm的皱纹盘鲍雌与日本大鲍雄的杂交鲍苗 180余万粒,单位面积出苗量为3 300余粒/m2。这些杂交鲍苗,经过 1年多的室内饲育,至 2000年 11月平均个体壳长达 37 mm,最大个体壳长达 45 mm,显示出了良好的生产性状和一定的杂种优势。
The use of imported from Japan, abalone, abalone Haliotis discus hannai and China made a hybrid seedling experiment. In 540 m2 of abalone seedlings, the seedlings were collected at normal temperature in June, 1999 to November of the same year, and more than 1.8 million hybrid abalones were cultivated with an average shell length of 17.9 mm. Emergence for more than 3 300 tablets / m2. After more than one year’s in-house feeding, the average length of individual shell was 37 mm and the largest individual shell length was 45 mm. These hybrid broomlings showed good characters and certain heterosis.
