Use of Sodium Chloride and MS – 222 in Transportation of Juvenile Siamese Fighting Fish (Betta splendens)

Abstract

Some responses of juvenile Siamese fighting fish (Betta splendens) to sodium chloride and the anesthetic MS – 222 were investigated in transportation. The static bioassay was used to estimate the acute toxicity of MS – 222 on juvenile Siamese fighting fish. The 96 – hour median lethal concentration (TL 50) for MS – 222 was 174.58 ppm. The concentration of MS – 222 that induce stage I (sedation) was 65 – 70 ppm. The 50 hours lived juvenile Siamese fighting fish transport with MS – 222 (65 and 70 ppm) and sodium chloride (0.5% and 1.0%) in plastic bags with and without additional oxygen. The result showed non significant different on survival rate in each treatment. This study showed that the anesthetic MS – 222 and sodium chloride have non – effect in increasing the survival rate.
