Seven diets with varying digestible protein/digestible energy (DP:DE) ratios were tested for growth and nutrient retention in fish body. Six test diets containing DE levels of 310, 3.30 and 360 Kcal/100 g at low (24%) and sub-optimum (28%) DP levels were tested against control having 30% DP and 3100 Kcal/100 g DE. However, the main protein source in control diet was fish meal while in all other six test diets corn gluten meal was provided. Significant differences (p<0.05) were observed in the percentage live fish weight gains at different levels of dietary protein and energy. Control fish receiving 30% dietary DP and protein/energy ratio of 81.93 gave the maximum gain in weight of 148.80±5.50%. However, among the six test diets, dietary P/E ratio of 73.75 shared the maximum weight gain (122.29±8.27%). Increase in dietary energy beyond 425.90 kcal/100 g resulted in significantly poor growth. Feed intake by the fish increased significantly with increasing dietary protein while decreased non-significantly with the increased dietary lipid and energy. The results indicate consumption dependent protein and energy retention in fish body as a function of dietary protein level. |

The water was alkaline throughout the stretch under study. The electrical conductivity of water at Hudiara nulla was the maximum due to the input of large amounts of salts and other nutrients in thiS tributary. Dissolved oxygen contents were significantly lower at Farrukhabad nulla, Munshi hospital nulla, Baker mandi nulla and Hudiara nulla than rest of the sampling stations. These significantly low values of dissolved oxygen corresponded inversely with the metal ion concentrations in water. There were significant variations among different sampling stations for heavy metals toxicity and physico-chemical variables viz. total hardness, water temperature, dissolved oxygen, pH and electrical conductivity. The variable significance of different parameters with positive and negative partial regression coefficients at different sampling stations were due to the difference of these stations for metals toxicity levels. On the whole, both zinc and iron toxicities in water were positively and significantly dependent on water temperature while negative but significant on pH of water. |

Response of five levels of nitrogen, viz. 0.10, 0.13, 0.16, 0.19 and 0.22 g N/100 g fish daily, from broiler droppings towards planktonic productivity of major carps rearing ponds. Six genera of Chlorophyceae, viz. Chlamydomonas, Closterium, Microspora, ❑edogonium, Pandorina, Spirogyra; two genera of Chrysophyceae including Botryocaccus, Synura; and three genera of Bacillariophyceae (Cyclotella, Cymbella and Navicula) were recorded during different months in six treatments. As regards Dinophyceae and Euglenophyceae, the genera observed were Peridinium and Euglena respectively. Myxophyceae included the genera Anabaena, Microcystis and Oscillatoria. Zooplankton represented by ciliates (Protozoans) and 10 other genera in all treatments except under 0.16 g level of nitrogen. However, the increase beyond 0.16 g nitrogen level showed gradual decrease in zooplankton productivity upto 0.22 g nitrogen level. The correlation coefficients between phytoplankton and zooplankton productivities, under all the treatments, were positive and significant. |

Twenty isolates of Pseudomonas sp., were tested for the control of soilborne root-infecting fungi like Macrophomina phaseolina, Fusarium solani and Rhizoctonia solani under laboratory and greenhouse conditions. In dual culture plate assay, strain 78 inhibited all the test fungi. Other Pseudomonas sp., failed to check the radial growth of M. phaseolina whereas isolates 51 and 82 significantly inhibited radial growth of F. solani and R. solani. Three isolates of Pseudomonas sp., (51, 78 and 82) when used as seed dressing or as soil drench showed substantial reduction in root-rot infection caused by M. phaseolina, F. solani and R. solani in mungbean. Strain 78 was found to be most effective in the control of root-infecting fungi. Of the root-infecting fungi, R. solani was most susceptible to Pseudomonas sp. |
