摘 要:[目的]探索不同饵料对鲎虫生长、寿命、生殖的影响。[方法]用7类饵料投喂鲎虫幼体进行饲养试验,研究鲎虫背甲长、相对增长率、特定生长率、寿命、产卵量。[结果]不同饵料饲养条件下,雌性个体背甲长为6.1~9.8mm、相对增长率为113.9%~302.9%、特定生长率为0.043%/d~0.067%/d、寿命为15.5~33.8d、产卵量为51.7~457.5;雄性个体背甲长为5.3~8.9mm、相对增长率为141.6%~267.5%、特定生长率为0.038%/d~0.055%/d、寿命为18.8~34.7d。3种饵料混合组背甲长、相对增长率、寿命、产卵量最高,其次为2种饵料混合组、单一饵料组。[结论]投喂不同饵料对鲎虫幼体的生长、寿命、产卵量影响显著。[Objective] The aim was to investigate the effects of feeds on growth,longevity and fecundity of tadpole shrimp.[Method] The tadpole shrimp(Triops granaries juveniles)were fed various traits for culture,which affected carinal length,relative growth gain,specific growth rate,longevity,fecundity and egg production profoundly.[Result] Under artificial conditions,the detection results of female and male tadpole shrimp are as following:average carinal length,6.1-9.8 and 5.3-8.9 mm;relative growth rate,113.9%-302.9% and 141.6%-267.5%;specific growth rate,0.043%/d-0.067%/d and 0.038%/d-0.055%/d;and longevity,15.5-33.8 d and 18.8-34.7 d.Each female tadpole shrimp gave 51.7-457.5 eggs.The carinal length,relative growth gain,longevity,and egg production were highest in the tadpole shrimp fed with the mixture of the three kinds of baits,followed by the mixture of each two kinds of baits and each kind of bait.[Conclusion] Different kinds of feed affect growth,longevity and egg production greatly.
