本文件没有需要界定的术语和定义。

4环境条件

场地环境应符合NY/T391的规定。水源水质应符合GB3838（Ⅲ）与GB11607的规定。

5主要设施

5.1亲虾培育设施

宜选用规格为2m×2m×1.5m或2m×3m×1.5m、网目网眼规格为3mm的聚乙烯无结网箱，

用浮筒架设，每排网箱留0.5m～1.0m人工通道，每两排网箱留2m宽水道，培植水雍菜、水芹菜等

水生植物。网箱设置在面积3000m2～6000m2的池塘中，池塘水深2m左右，进排水独立设置。网箱面

积占池塘总面积的1/4～1/3。

DB43/T2390—2022

5.2繁殖设施

5.2.1大棚

宜采用钢架塑料大棚，应能调光、保温、防雨和通风，面积1000m2～1500m2。

5.2.2配对池

在大棚内建2m×4m或3m×6m的水泥池，池深1m左右，池底坡比3％～5％。占大棚面积30％

左右。

5.2.3孵化池

在大棚内建5m×10m或5m×15m的水泥池，内壁光滑，进排水口用网眼规格0.6mm的过滤网

双层套袋过滤，池底四周高，中间低，坡比3％～5％，在池底最低处设置出水口、集虾槽及水位保持

装置。孵化池占大棚面积60％左右。

5.3苗种培育设施

在大棚外按孵化池面积1∶10配套建设苗种标粗池，单池面积为500m2～1000m2，池深1m左右。

池底一端设内口径为10cm～20cm的排水管。

5.4配套设施

配备控温、控光、供电、充气和水处理设施，均应符合SC/T6093的相关技术要求。

6亲虾培育

6.1后备亲虾选择

应从有资质的苗种场采购，经检验检疫合格。种虾应附肢齐全、无损伤、体表无附着物，体格健壮、

活动能力强；体长6cm以上，雌虾体重不低于30g/只，雄虾体重不低于35g/只。

6.2培育

雌、雄亲虾应分箱培育，培育密度为15尾/m2～20尾/m2。投喂亲虾专用饲料（粗蛋白质不低于30％，

赖氨酸不低于1.40％，粗脂肪不低于5％），饲料符合GB13078和NY/T471的规定。雌虾定期拌喂鱼

糜或维生素E，促进性腺发育。

水质应保持pH8.0～8.3，氨氮小于0.4mg/L，溶解氧大于5mg/L。

7人工催产

7.1亲虾挑选

8月底～9月初，检测雌虾卵巢发育情况，待卵巢发育到Ⅳ期个体达80％以上时，进行人工催产。

7.2药物催产

可使用人绒毛膜促性腺激素（HCG）催产，每只雌虾100IU～150IU，雄虾剂量减半。注射部位为

腹部第二体节，注射时针头与腹部呈30度角左右，深度为3mm左右。

2

DB43/T2390—2022

7.3配对

将注射后的亲虾，按雌雄比（2～3）∶1配对放入产卵池，放养密度20只/m2～30只/m2，产卵池保

持微流水，溶解氧5mg/L以上。

7.4抱卵

配对48h后，应将雄虾移走，雌虾抱卵后转移至孵化池，集中孵化。

8控温孵化

8.1抱卵虾投放

放养密度40只/m2～50只/m2，水温控制在20℃～25℃，溶解氧5mg/L以上。

8.2日常管理

受精卵开始脱膜，可适量投喂亲虾专用饲料。待稚虾大多数离开母体可自由游动时，将亲虾移走，

进行稚虾培育。

9苗种培育

9.1稚虾培育

饵料以培育浮游生物为主，适当投喂小龙虾开口粉料。15d～20d后，稚虾体长2cm～3cm时，

可出售或分池培育。

9.2幼虾培育

宜在室外苗种培育池进行，放养密度为300尾/m2～500尾/m2，以投喂小龙虾幼虾配合饲料为主，

饲料符合GB13078和NY/T471的规定。培育至次年3月上中旬，幼虾体重2g～3g时，可起捕出售

或转塘养殖成虾。

9.3日常管理

培育期间定期换水、增氧，透明度保持30cm～40cm，溶解氧5mg/L以上。尾水排放按DB43/1752

的规定执行。

9.4病害防控

按照SC/T1135.4的规定执行。

10捕捞与运输

10.1捕捞

稚虾宜采用排水法，用网具在集虾槽或排水口收集；幼虾宜采用网眼规格为1.6cm的地笼捕捞。

10.2运输

稚虾带水充氧运输，幼虾塑料框铺水草保湿运输。
