【摘要】 以鲜鱼虾肉、自制配合料为饵料 ,在室内和室外水泥池内进行黄颡鱼亲鱼培育 ;采用DOM、PG、LHRH-A2、HCG不同剂量组合进行人工催产 ;采用静水和微流水两种方式进行孵化。在孵化网箱内进行鱼苗培育。结果表明 :黄颡鱼亲鱼喜食新鲜饵料 ,也易驯食配合饲料 ,室内和室外人工条件下均能获得成熟亲鱼 ;用DOM +HGG +LHRH -A2或PG +HCG +LHRH -A2的混合剂人工催产 ,微流水孵化效果较好 ,催产率为 5 0 %～ 10 0 % ,受精率为 60 %～ 90 % ,孵化率达 70 %～ 90 % ;小网箱培育鱼苗 ,成活率高 ,规格整齐更多还原

【Abstract】 With fresh meals of fish and shrimp?artificial formulated diets,seedstocks of Pseudobagrus fulvidraco were reared in outdoor or indoor square ponds.Injected the mixture hormones of different dose of DOM?PG?LHRH-A2 and HCG into the seedstocks to induce spawning.Incubated the fertilized eggs with quiet or slow flowing water.Culture the fry in the hatchery cages.The results showed that:(1)The seedstocks of Pseudobagrus fulvidraco favored fresh meals and could be domes ticated to eat formulated diets as well.Under artificial conditions no matter outdoor or indoor,ripe seedstocks could be obtained;(2)The mixture of DOM?HCG and LHRH-A2 or that of PG?HCG and LHRH-A2 could succeed in artificial induce spawning.With slow flowing water to hatch,the hatchery effect was better.Induce spawning rate was 50 %-100 %,fertilized rate was 60 %-90 %,hatchery survival rate was 70 %-90 %;(3)Culturing the fry in the small hatchery cages resulted in high survival rate and identical body size.更多还原
