摘要
报道了无特定病原中国对虾种群 (SPF)选育的结果 ,主要介绍1999～2000年选育子3代和子4代的养殖结果。1999年选育对虾子3代养殖平均1788kg/ha ,对虾平均体长13.69cm ;而对照池中暂养池对虾体长3～4cm发病死亡 ,养殖池对虾体长6cm发病死亡 ;2000年选育对虾子4代养殖平均3168kg/ha,对虾平均体长15.00cm ;对照池产量为3450kg/ha ,对虾平均体长13.30cm。说明经过连续几代的人工选育 。
The result of Special Pathogen Free(SPF) of Penaeus chinensis group on selective breeding was reported, it′s about culturing result of the third filial generation(F3) and the fourth filial generation(F4) in 1999 and 2000.Per hectare yield of F3 was 1 788 kg in 1999, average body length was 13.69 cm; while the average body length was 3 4 cm in the temporary pool of control pools because of explosive epidemic disease, and the average body length of the F3 dead when the disease happened was 6 cm in the culturing pool of control pools; Per hectare yield of F4 was 3 168 kg in 2000, the average body length was 15.00 cm; Per hectare yield of control pool was 3 450 kg , and the average body length was 13.30 cm. It demonstrate that the speed of growth has increased rapidly after successive several generation′s selective breeding.
