Argulus is a common parasite of freshwater fish, found in fisheries throughout the UK. Adult lice are flat, round, jelly-like parasites that feed on skin and mucus. Heavy infections can quickly cause irritation, condition loss and death. In addition, Argulus lice have been known to be the vehicle for other fish pathogens, including Rhabdovirus carpio, larval nematodes, and the fungus Saprolegnia.
Pathology caused by Argulus is related to the trauma induced by the attachment and feeding methods, and areas where feeding has taken place usually result in hemorrhagic spots. Lesions inflicted by the parasites often become necrotic and ulcerated, leading to secondary infections.
Innovative approach using herbal powerful active phytochemicals load to carbon nanoparticle (Graphene) for sustained delivery of herbal actives has attained a level of argulus control in pond water spread. One treatment can control Argulus for three weeks. One more addition of specialized nanoparticle helps control disease for longer time.
