摘　　要：采用6种天然饵料喂养清洁虾亲虾,分析其对亲虾性腺发育、繁殖性能以及受精卵质量的影响。性腺发育试验发现,投喂6种不同饵料亲虾性腺发育周期差异显著(P<0.01),最长的为鱼肉组(12.82±1.91)d,最短的为卤虫无节幼体组(11.46±1.76)d;卤虫无节幼体与桡足类组性腺指数、干物质含量及总蛋白质含量随着性腺发育显著增加(P<0.01),增加均在2倍左右。繁殖性能与受精卵质量结果表明,鱼肉组(3 357±621)(粒/g)亲虾相对怀卵量最大,卤虫无节幼体组最小(1 829±213)(粒/g);卤虫无节幼体[(0.110 9±0.016 3)mm3]组亲虾受精卵体积最大,乌贼组最小[(0.096 2±0.014 0)mm3];鱼肉组[(37.33±1.75)μg]的受精卵干重最大,虾肉组最小[(31.00±1.26)μg];桡足类组蛋白质绝对含量[(367.17±25.68)mg/g]在干物质中所占比例(72.34%)最高。此外,6个饵料组中所有亲虾在各抱卵周期内抱卵率与抱卵间期无显著差异。This study has analysed the effect of six natural diets on gonadal development , reproductive performance and, quality of zygote of a marine ornamental shrimp Lysmata amboinensis. The results of gonadal development show that there is a significant difference in development cycle of gonad with six diets （P 〈 0.01 ）, shortest in treatment of Artemia nauplius [ （ 11.46 ± 1.76 ） d ] and longest in prown meat [ （ 12.82 ± 1.91 ）d] ; GSI , dry matter and protein content from broodstoeks fed Artemia nauplius and copepods increased significantly along with gonad development （ P 〈 0.01 ） , all increased by twice approximate . The results of reproductive performance and quality of zygote show that relative fecundity in treatment of Spanish mackerel （3 357 ±621 ） eggs/g is most, and least in Artemia nauplius（1 829 ±213） egg/s ; volume is maximal in treatment ofArtemia nauplius[ （0. 110 9 ±0.016 3） mm^3] and minimum in sepia[ （0.096 2 ±0.014 0） mm^3] ; dry weight in treatment of Spanish mackerel[ （37.33 ± 1.75） μg] is maximal, and minimum in prown meat [ （31.00 ± 1.26） μg]; protein content （367. 168 9 mg/g） and percentage composition in dry matter of zygote（72.34% ） in treatment of copepods is maximal. Furthermore, there are no significant differences in incubating rate and incubating interval with six diets.
