摘要

Protective role of diet supplements (Spirulina, tamarind fruit pulp and their combination) on a freshwater fish G. affinis exposed at sublethal concentration of fluoride (F-) (10 ppm), Al(+3) (3 ppm) and aluminum fluoride (AlF3) (35.4 ppm) in the microcosms (15 L sized) for 30-60 days in winter (90 days in summer) has been reported. Toxic effects of chemicals were manifested as higher fish mortality (4-50%) and acid (approximately -30%) and alkaline phosphatase (25-50%) contents, but reduction in RBC counts (5-55%) and protein content (approximately -29%) compared with controls. Alterations in values of these parameters were found maximum in aluminum exposed fish suggesting it as the most toxic among the tested chemicals. Diet supplements reduced toxicity of tested chemicals, especially when Spirulina and tamarind were given together.
