摘  要：
用茜素络合物(ALC)对唐鱼(Tanichthys albonubes)进行荧光标记,通过测定唐鱼耳石的标记率、死亡率、SGR和DWG等指标,讨论不同浓度ALC对唐鱼耳石标记效果和对其生长和存活的影响,探讨应用该标记技术追踪唐鱼野外种群迁移行为的可行性。结果表明:在温度28~30℃,浓度50 mg·L-1、80 mg·L-1茜素络合物溶液中浸泡24 h,唐鱼仔鱼、稚鱼死亡率为0,其中80 mg·L-1浓度处理组耳石荧光标记环检出率为100%,而在100mg·L-1浓度下,仔、稚鱼死亡率均达到80%;幼鱼在浓度为80、100 mg·L-1条件下无死亡,其中100 mg·L-1浓度处理组耳石标记环检出率为100%,而150 mg·L-1浓度下幼鱼死亡率为44%;成鱼在100、150 mg·L-1浓度下无死亡,且耳石标记率均为100%,而在200mg·L-1浓度下成鱼死亡率达到100%;此外,稚鱼在80 mg·L-1最适浓度下浸泡24 h后继续饲养90 d,标记组和对照组死亡率均为0,两组体质量、SGR和DWG差异不显著;唐鱼仔稚鱼、幼鱼和成鱼耳石标记的最适茜素络合物浓度分别为80、100和150 mg·L-1。

摘  要：
The effects of alizarin complexone(ALC) on otolith marking,growth and survival of Tanichthys albonubes were studied,aiming to improve the applicability of this marking technique in tracing T. albonubes for a better understanding of its movement and migration pattern. Larvae,juveniles with the body length of 5. 8- 10. 5 mm(J5s),juveniles with the body length of 10. 8- 13. 2 mm(J10s),and adults of T. albonubes were selected in the experiment,the water temperature was 28- 30 ℃,and immerse time was 24 h. Larvae and J5 s of T. albonubes exposed to50 mg·L- 1and 80 mg·L- 1of ALC had a 100% survival rate,but those exposed to 100 mg·L- 1had a mortality rate of 80%. Under the condition of 80 mg·L- 1ALC,growth rings in otoliths detected by fluorescence microscope(GRFM) were found in all the larvae and J5 s. Under80 mg·L- 1and 100 mg·L- 1of ALC,all J10 s survived,but the mortality rate of J10 s exposed to 150 mg·L- 1of ALC was 44%. GRFM was found in all J10 s under 100 mg·L- 1of ALC.Under 100 mg·L- 1and 150 mg·L- 1of ALC,all adult fish survived with GRFM,but under200 mg·L- 1of ALC all adult fish died. Cultured for 90 days after exposure to ALC,J5 s had the similar body weight,SGR,DWG,and 100% survival rate as compared to the controls(P > 0.05). It was suggested that the suitable concentrations of ALC treating larvae,J5 s,J10s,and adults of T. albonubes for GRFM were 80 mg·L- 1,100 mg·L- 1and 150 mg·L- 1,respectively.
