Synopsis (short abstract) Extensive renal lesions caused by microsporidian infection were recorded for the first time in the kidneys of Indian major carp, Labeo rohita (Hamilton). Intracellular developmental stages of the parasite caused displacement of the host cell nuclei and ultimately destroyed the renal epithelial cells releasing the parasite into the tubular lumen. In extreme cases, the tubular lumen was found to be completely filled by the microsporidian parasite and there was severe degeneration and necrosis of t he renal tubules. Proliferation of haematopoetic tissue in between the renal tubules was observed. The release of the microsporidian parasite into the renal interstitium provoked granulomatus inflammatory reactions.

    Observations on the efficacy of carbonic acid as anesthetic for Indian major carps

    Various anaesthetics have been in use in culture fishery operations. The present communication describes the efficacy of carbonic acid as anaesthesis for Indian major carps. Different dose levels were tried and the results discussed. It was observed that at lower concentrations the fish were anaesthetized slowly and less deeply whereas at higher concentrations the effect was rapid with greater sedation. The duration for which the fish could be safely held in the anaesthetizing bath also varied a ccording to the concentra tion of carbonic acid and size of the fish. For smaller fry, the safe dose range of carbonic acid was rather very narrow. No significent differences could be observed between the three species of Indian major carps in their response towards the carbonic acid anaesthesia.

    Effects of green manure on fish production in polyculture ponds with silver carp and bighead carp as main species

    Four types of green manure were used in the polyculture ponds with silver carp and bighead carp as the main species. Direct application of green manure resulted in a higher fish production ranging from 19.59 to 25.33 kg/ha/day. Sudan grass was best among four types of green manure.
