Effect of nanoformulated cypermethrin, a parasiticide in Labeo rohita fingerlings: impact on biochemical, haematological, and stress response.

Cypermethrin is a pyrethroid insecticide used in aquaculture farms against ectoparasites. The conventional pesticide formulations are now being found to be greatly ineffective at low dosages, and their indiscriminate usage may cause undesired effects in ecosystems. So, the current study was designed to develop a nanoformulation of cypermethrin that would have many advantages over conventional pesticide formulations, and the toxic effects of this formulation were then tested on the carp Labeo rohita fingerlings.

infection in a new host in intensive culture system and its control by doramectin.

The present study explored the susceptibility of subadults to infection subsequent upon their first introduction to an intensive culture system that had a previous history of infection and evaluated the efficacy of doramectin against the parasite. All the introduced to the culture pond got infected demonstrating 100 % susceptibility of this species to infection. Pathological changes caused by the parasite as evidenced by the extensive hemorrhage and tissue necrosis of the host at the point of parasite attachment was most severe in .

Efficacy of two avermectins, doramectin and ivermectin against Argulus siamensis infestation in Indian major carp, Labeo rohita.

The efficacy of two avermectins, doramectin and ivermectin via oral and parenteral routes and their prophylactic effects against Argulus siamensis infestation in Indian major carp, Labeo rohita was studied. Doramectin and ivermectin were fed once to L. rohita sub-adults naturally infested with A.

Efficacy of doramectin against natural and experimental infections of Lernaea cyprinacea in carps.

Efficacy of doramectin administered via oral and parenteral routes against experimentally induced and natural infections of the copepod parasite Lernaea cyprinacea in carps was studied. Administration of doramectin incorporated in feed at 1mg/kg b.wt.
