Abstract
Argulosis is one of the constrain in ornamental fishery as ectoparasite infestation. Allium sativum is recognized as a potential anti-parasitic agent against Argulus japonicus. The present study was aimed to investigate anti-parasitic effect of Allium sativum against Argulus japonicus in Carassius auratus recorded after 5 days. The parasite was cultured under laboratory condition to infest the host. Host fish was concurrently subjected to Allium sativum at the rate of 0.125g/L, 0.25g/L and 0.5g/L. Morphometric, growth, survival, biochemical, histopathological, haematological and micropathological indices were recorded after the challenge test. A. sativum reduced intensity of infestation(0.62±0.38), behavioral morbidity and increased the parasite mortality rate in addition to the haemotological and biochemical indices of the host. However, increasing the concentration to A. sativum to 0.5g/L was found to be fatal resulting in declining survival rate (84.00±21.90). Low concentration of A. sativum (78.00±3.74) stimulated feed intake. Overall, 0.25g/L of A. sativum offered to C. auratus was found to be optimum, promoting the growth rate during the A. japonicus challenge test.
