于1988年4月和1991年4月分别从厄瓜多尔和美国引进南美洲白对虾仔虾,经驯化、养成和室内人工越冬后,采用单侧眼柄切除手术人工催熟,以试管授精和人工植荚方法进行该种的繁殖技术试验。结果表明,(1)体长在13—16cm的南美洲白对虾雌虾,一般在摘眼后的1—2周内开始性腺发育;产卵量通常为3—10万粒;产卵后的雌虾卵巢可再次发育,最高产卵次数高达19次。(2)应用高频电针法取荚的成功率和取荚后雄虾的存活率均为100％;用上述方法取得的精荚内的精子无需“获能”即可使卵子受精。(3)假裂现象在南美洲白对虾的未受精卵中较为普遍。
In April 1988 and April 1991 were introduced from Ecuador and the United States, respectively, the South American white shrimp larvae, after acclimation, development and indoor artificial overwintering, the use of unilateral eyelid resection surgery artificial ripening to IVF and artificial Planting pod method of breeding technology test. The results showed that: (1) Females of P. vannamei with body length of 13-16 cm generally started gonadal development within 1-2 weeks after picking; the number of fecundity was usually 3-10 million; Female and ovary can be re-developed, the maximum number of spawning up to 19 times. (2) The success rate of pod application by high-frequency electro-acupuncture and the survival rate of male pod after podding were both 100%. The sperm in the spermatophore obtained by the above method could fertilize the egg without “gaining”. (3) Scratches are common in unfertilized white shrimp in South America.
