The study was conducted to compare the effect of three different fry rearing systems such as: hapa, cistern and pond on the growth and survival of goldfish (Carassius auratus ) fry. A total of 645 fry (mean initial weight: 0.0071 mg) were randomly distributed in the three treatments (systems) each having three replications. The stocking density was same in all the treatments with respect to the water volume of the systems which was 10 fry/hapa, 125 fry/cistern and 80 fry/pond. The trial lasted for 40 days. The water quality parameters were favorable in all the treatments during the period of the study. The growth and survival of goldfish fry varied among the systems. Highest average weight gain and specific growth rate (SGR) were observed in pond followed by hapa and cistern. On the other hand, survival rate was highest in cistern followed by hapa and pond. It can be concluded from the study that the pond was the best system in terms of growth rate and cistern was the best system for survival of gold fish fry.Res. Agric., Livest.

Environmental pollution resulting from oil exploitation and exploration has impacted negatively on the biodiversity of the affected areas. Therefore, this study investigated the response of soil microorganisms to oilfield wastewater. The oilfield wastewater and soil samples were collected from an onshore oil producing platform fortnightly for a period of three months and microbiological analyses were performed using standard methods. Soil around pond average counts for THB and HUB (Log10 CFU/g) were 7.32 to 7.35 and 4.16 to 4.22 respectively. Soil 80 m away from pond average range for THB and HUB were 7.38 to 7.40 and 3.32 to 3.34 respectively. For TF and HUF, Soil around the pond mean recorded 4.65 to 4.85 and 4.12 to 4.16 (Log10 CFU/g) respectively. Mean monthly counts for soil 80m away TF and HUF (Log10 CFU/g) were 5.03 to 5.05 and 3.26 to 3.34 respectively. Soil around the pond recorded lower total heterotrophic bacteria count and total fungi count but higher hydrocarbon utilizing bacteria and hydrocarbon utilizing fungi than soil 80 m away. There was significant difference (P<0.05) between the THB and HUB in the various samples. For the fungi count there was no significant difference (P>0.05) between TF and HUF in all the samples except in sample obtained from soil 80 m away from pond. Bacteria species isolated from the study include: Bacillus, Aeromonas, Micrococcus, Staphylococcus, Chryseomonas, Proteus, Pseudomonas, Klebsiella. Apart from Aeromonas and Chryseomonas the rest of the isolate were identified also as hydrocarbon utilizing bacteria. While fungi species isolated includes: Aspergillus fumigates, Aspergillus niger, Aspergillus flavus, Saccharomyces cerevisiae, Geotricum, Trichoderma, Fusarium and Penicillium. Hydrocarbon utilizing fungi that occurred includes: Aspergillus niger, Aspergillus flavus, Fusarium, Penicillium and Saccharomyces cerevisiae. The response of these microorganisms in the oil polluted environment suggests that the isolated bacteria and fungi could utilize the oil as energy and carbon source and could be effective in the cleanup of the polluted sites.

Ornamental fish culture is considered as one of the most important source of home entertainment, because of its diversity and beauty of picturesque colors. Trichodiniasis of fishes causing harm and economic losses in this fish industry. There are many records of trichodinids ectoparasites infesting fish have been found throughout the World, but no such attempt has been made to study the parasitic group infesting ornamental fish, preferably oranda goldfish (Carassius auratus auratus L.) in India. A parasitological search in some ornamental fish farms have been revealed for the first time the occurrence of trichodinid species previously described so far from the oranda goldfish in India. They are Trichodina reticulata, Trichodina mutabilis, Trichodina acuta, Trichodina ngoma, Trichodina nandusi and Trichodina domergui. These parasites have not been reported earlier from the oranda goldfish in India. The paper deals with the diversity, distribution and taxonomic descriptions of these six trichodinid species based on the wet silver nitrate impregnated observations along with new host, locality and prevalence of infestation.

Commercial Fish Food

An interesting feature of the goldfish liver is the morphology of the hepatic plate, which is always formed by a two-cell layer of hepatocytes. Hepatic plates of the goldfish liver contain an infrequently seen second type of cell, in the centers of plates between two hepatocytes. A TEH study by Yamamoto (1) demonstrated ultrastructural differences between hepatocytes and centrally located cells in hepatic plates; the latter were classified as ductule cells of the biliary system. None of the previous studies clearly showed a three-dimensional organization of the two cell types described. In the present investigation we utilize SEM to elucidate the arrangement of hepatocytes and bile ductular cells in intralobular plates of goldfish liver.Livers from young goldfish (Carassius auratus), about 6-10 cm, fed commercial fish food were used for this study. Hepatic samples were fixed in 4% buffered paraformaldehyde, cut into pieces, fractured, osmicated, CPD, mounted Au-Pd coated, and viewed by SEM at 17-20 kV. Our observations were confined to the ultrastructure of biliary passages within intralobular plates, ductule cells, and hepatocytes.
