  • The present paper deals with methods and effects of using alizarincomplexone (ALC)and chlorydrate of tetracycline (CHTC) to mark larval and juvenile Gobiocypris rarus and Carassius auratus pengze Var. To immerse the two species in 50-100mg/ L ALC solutions for 6-24h, a well-defined mark on otolith was induced.A well-defined mark on otolith was also observed when immersing larval Carassiusauratus pengze Var in 150-250mg/L CHTC solutions for 12-24h. However, onlyimmersing -caused mortality was observed in G. rarus when immersed in CHTC solution. suggesting that TC may not be suitable for being used as marking solution.Under UV light,the mark of ALC in the otoliths is a scarlet-pink fluorescent zone,and that of CHTC is a yellow fluorescent zone.
