Efficacy of different fertilizers on the growth and survival of brackishwater catfish, Mystus gulio (Hamilton) fry in nursery ponds has been evaluated with three fertilizer treatments (T) viz., T1 - only organic (cattle dung @ 5 tons/ha), T2 - only inorganic (urea @ 50 kg/ha + TSP @ 60 kg/ha) and T3 - mixture of organic + inorganic (cattle dung @ 2.5 tons/ha + urea @ 25 kg/ha +TSP @ 30 kg/ha). After four weeks rearing, survival of fry was highest (69.35 ± 8.79%) in T1 which was significantly higher than those of T2 (46.01 ± 4.17%) and T3 (57.19 ± 6.22). But no significant difference in final length (2.70 - 2.79cm) and final weight (0.83 - 0.93 g) among three treatments was observed. Physicochemical variables of water and planktons of different treatments were recorded and discussed.Bangladesh J. Zool. 41(1): 21-27, 2013

The study was conducted to determine a suitable feed for the desirable growth ofriverine catfish Rita rita (Hamilton) from January 2006 to December 2006. The experiment hadthree treatments with three replicates. Nine chambers of the raceway each of size 1.83 × 1.12 sqmeter were used. Local prawn, chicken viscera and commercially available formulated feed (CP)were supplied in treatment T1, T2 and T3, respectively at the rate of 7% body weight. Feed wassupplied twice in a day in the early morning and in the evening as the fish is nocturnal. The initialaverage weight of fish was 24.93±0.05g, 24.99±0.04g and 24.95±0.04g in T1, T2 and T3,respectively. The final weight of the fish under three treatments was 425.05±1.04g, 425.68±1.05gand 177.61±1.45g respectively. The initial length was 8.48±0.02, 8.49±0.02 and 8.50±0.01 in T1, T2and T3, respectively. The final length was 25.22±0.06 cm, 25.21±0.14 cm and 14.87±0.13 cm in T1,T2 and T3, respectively. The mean final weight and length was significantly (p<0.05) higher in T1and T2 compared with T3. However, there was no significant difference (p>0.05) between T1 and T2in terms of final weight and length was concerned. Better growth performances, however, wereobserved in T2 and T1, where prawn and chicken viscera were supplied as feed respectively.Lowest growth performance was observed in T3 where formulated feed (CP feed) was supplied.Key Words: Riverine Catfish; Feed; Growth; SGR; Survival.DOI: 10.3329/ujzru.v28i0.5279Univ. j. zool.

Nursery evaluation of catla spawn was carried out by feeding three iso-nitrogenous diets (35% protein in raw and cooked form) for a period of 30 days. The three test diets (treatments) in raw form were: T1 - groundnut oil cake (GOC) + rice bran (RB) + vitamin-mineral (V-M) premix; T2 - GOC+RB+fish meal (FM) + V-M premix, T3 - GOC+RB+prawn meal (PM)+V-M premix. The diet groups GT1, GT2 and GT3 respectively were same feed combinations in cooked form. Incorporation of prawn meal as animal protein source led to significantly higher final weight, final length, % weight gain, specific growth rate (SGR) and protein efficiency ratio (PER) compared to diet with and without fish meal incorporation. Whereas, diet containing fish meal improved the fry growth and survival rate only when it was cooked. Cooked diet either with fish or prawn meal incorporation led to better fry growth over the respective non-cooked diets, revealing the advantage of cooking process for better nourishment in catla fry during nursery phase.

Murshidabad district is the highest jute producer district in West Bengal where maximum numbers of ponds beels, canals and irrigational channels are being used for jute retting from July to September and after retting, water bodies remain uncultured. But few farmer’s, they were culture traditionally with IMC and exotic carps and getting very low yield (3.66q ha-1yr-1). In that condition Murshidabad KVK has designed one OFT trails having three treatments, Farmer’s Practice (FP), Technology Option-I (TO-I) and Technology Option-II (TO-II) on air-breathing fish pangas (Pangasius pangasius) and conducted in farmers’ field for three years. To find out the suitable fish species, observed water parameters (pH, DO mg L-1), stocking density (nos./ha), length (cm), weight (g), survival rate (%), yield (q ha-1yr-1), cost of culture (Rs. ha-1yr-1) gross return (Rs. ha-1yr-1), net return (Rs. ha-1yr-1), BC ratio and disease incidence etc. The effect of water pH and DO (mg L-1) in post jute retting pond and fish stocking pond indicate, there were a statistically significant difference between three treatments at (p <.05). Stocking density in three treatments were 15000 nos. ha-1 (IMC and exotic carps), 11250 nos. ha-1 and 15000 nos. ha-1 (pangas, size 2.5”) . In this trial it was observed that the mean (SD) initial length (cm), initial weight (g) and final length (cm) were not statistically significant at p >.05 but in case of final weight (g) and weight gain (g) there were statistically significant at p<.05. The survival rate (%) was lowest in FP (35.04±4.51) and highest in TO-I (67.55±17.50) and not statistically significant (p >.05). The mean (SD) yield (q ha-1yr-1) was high statistically significant difference found among three treatments (p <001). The average net profits were Rs.65680.0, Rs. 223841.0 and Rs. 337551.0 ha-1 yr-1. in FP, TO-I and TO-II, respectively. The highest mean B:C ratio was 2.44 in TO-II. With the all concerned it was observed TO-II gives the best result among these three treatments in these three years trials.

This experiment was designed with three experimental treatments namely T1 (natural feed), T2 (feeding with 10% body weight) and T3 (feeding with 5% body weight) for ten weeks. In the content of 33.8% of crude protein (CP), 11.2% of crude fiber (CF), 6% of fat and 10.2% of ash content feed were used as an experimental diet in this experiment. The stocking densities were 280 fish decimal-1 in three treatments where the mean initial weight of fry was 20 ± 0.2 g in all treatments combined and at the end of the experiment the mean final weight was found as 58.9 ± 2.86 g, 134.4 ± 3.62 g and 142.5 ± 4.23 g for T1, T2, and T3 respectively. Mean initial length was 10.2 ± 0.01 cm in three treatments and final length was found as 14.58 ± 1.60 cm, 18.74 ± 1.23 cm and 20.16 ± 2.08 cm in T1, T2 and T3 respectively. The mean weight gains 38.9 ± 1.53 g, 114.4 ± 3.05 g and 122.5 ± 1.5 g, mean length gain 4.38 ± 0.24 cm, 8.54 ± 0.65 cm and 9.96 ± 0.59 cm, mean SGR 1.76%, 3.5% and 3.82% were recorded in T1, T2 and T3, respectively. The highest weight gain, length gain and SGR were found in T3 and the lowest was found in T1. The survival rate was 82%, 88% and 94% in T1, T2 and T3, respectively. FCR values were found as 3.49 ± 0.5 and 2.51 ± 0.4 in T2 and T3. The result demonstrated that feeding with 5% body weight had a better effect on the growth and survival rate of monosex (male) O. niloticus.

The aim of the investigation was to determine the effect of different food on growth and survival of Nandus nandus larvae. The experiment was conducted for 20 days in twelve (12) cisterns (9× 6×2.5ft) to assess the effect of Zooplankton, Artemia, Tubifex and Brand Nursery Feed on growth and survival of N. nandus larvae in cistern condition. The growth of N. nandus larvae varied significantly (P<0.05) with live feed and artificial feed. Zooplankton treatment showed the best growth performance and Brand Nursery Feed showed the poorest. There was significant difference in final weight of larvae fed with live and artificial feed. Final weight of live feed Zooplankton was 241.79±17.25g, Artemia-210.37±20.16g, Tubifex-226.36±15.72g and Brand Nursery Feedwas195.08±15.53g respectively. Specific growth rate (%) and percentage (%) weight gain were also best in case of Zooplankton fed N. nandus larvae. Different water quality parameters were more or less same in different treatments.Asian J. Med. Biol. Res. March 2017, 3(1): 114-119

A four week experiment was conducted to evaluate the effect of isoproteinous (35%) feed prepared named diet 1, 2, 3 and 4 respectively by substituting 0%, 50% , 75% and 100% fish meal with meat and bone meal in view of preparing a cost effective tilapia (Oreochromis niloticus) fry feed. The four experimental diets (diet 1 to 4) each were randomly assigned to twelve hapas with three replications. Tilapia fry (0.011g) were randomly stocked in 100 fry/9ft² hapa and fed five times a day up to their apparent satiation. The results of the study showed that the weight gain, specific growth rate (SGR), the apparent net protein utilization value and survival (%) of the fish were significantly  (P<0.05) higher and better feed utilization with lower FCR value was observed in fish fed on the diet 4 where meat and bone meal was used as sole source of protein base. There was no significant difference between the carcass moisture and lipid of fish fed with different experimental diets. The results of the study indicated that diet 1 containing fish meal (45.15% Fish meal, 27.43% Rice bran and 27.43% Wheat flour) can be replaced by meat and bone meal containing diet 4 (54.06% Meat and bone meal, 22.97% Rice bran and 22.97% Wheat flour) with no adverse effects on growth and survival of O. niloticus. Before recommendation several trials will be necessary in different farms to be  sure of the reproducibility of the result obtained in the present experiment. Cost- benefit analysis reveals that the   meat and bone meal containing diet certainly provides cheaper feed.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12110   J. Bangladesh Agril.

Feed Conversion Rate

The performance of Nile tilapia (Oreochromis niloticus) raised in cages furnished with an automatic dispenser, supplied at different frequencies (once per hour and once every two hours) and periods (daytime, nighttime and both) was evaluated. Eighteen 1.0m³ cages were placed into a 2000m² pond, two meters deep with a 5% water exchange. One hundred and seventy tilapias, with initial weight of 16.0±4.9g, were dispersed into each 1m³ cage and the feed ration was adjusted every 21 days with biometry. Data was collected from March to July (autumn and winter). Significant difference to final weight (P<0.05) among treatments was observed. The increase in feeding frequency improves the productive performance of Nile tilapias in cages and permitted better management of the food. The better feed conversion rate for high feeding frequency (24 times day-1) can result in saving up to 360kg of food for each ton of fish produced, increasing the economic sustenance for tilapia culture and suggesting less environmental pollution.

Aims: This study aimed to determine the effective percentage of telang leaf meal on feed to increase antioxidant levels in tilapia liver feed. Study Design: A total of 12 aquariums with sizes 60 x 40 x 40 cm3and volume 96 L prepared and filled with 30 L water. Heater was installed and the temperature was raised slowly until it reached 34℃. Feed in the form of a mixture of telang leaf flour and commercial feed was given 3 times a day according to treatment and with the provisions of 3% of body weight of fish per day. Analysis of antioxidant levels was analyzed from the content of the superoxide dismutase enzyme as an antioxidant bioindicator in the body of the fish. Place and Duration of Study: The cultivation was carried out at Ciparanje Hatchery and Fisheries Area, Faculty of Fisheries and Marine Science, Universitas Padjadjaran and Dismutase Superoxide Level Analysis was carried out at the Central Laboratory of Universitas Padjadjaran in June and July 2019. Methodology: This research was carried out by giving high temperatures as a source of stress, for 40 days. Tilapia were given a mixture of telang leaf meal as a source of anti-oxidants. At the end of research, Test liver fish taken superoxide dismutase levels were observed and analyzed descriptively. Daily growth and survival rate of fish were analysed using F test at 5% level, and if there were significant differences, Duncan's test was performed. Results: By giving heat stress continuously for 40 days the result is obtained the highest average superoxide dismutase level in treatment B (telang leaf meal 5%) as much -0.92 inhibition and lowest in treatment D (telang leaf meal 15%). A decrease in SOD levels identifies a decrease in antioxidant activity in the body of Tilapia. Daily growth rate obtained showed no significant difference. The fish will continue to grow but not as rapidly, because tilapia utilize protein up to 40% of commercial feed used to repair cells damaged during stressful periods and as a source of energy. Survival of fish decreases with increasing concentration of telang leaf flour, where the feed given has been mixed and resulted in the fish's response to the feed decreases, consequently not only the fish adapted to the environment, fish also adapt to new types of feed. Conclusion: Based on the results of research that has been done then conclusions can be drawn that the addition of telang leaf mealup to 15% in commercial feed by giving heat stress since the beginning of the culture period does not provide an effect of increasing antioxidant levels.

Broiler chicken is one of the poultry farms whose growth is fast, can meet the needs of meat in the community. To accelerate chicken growth, addition of Antibiotic Growth Promoter (AGP) was added to the beverage. This study aims to analyze the effect of monensin antibiotic administration on weight gain. The research method uses a Completely Randomized Design (CRD), consisting of 4 treatments and 6 replications. P0 Treatment (Control): Basal ration + Water boiled in 1 liter; P1: Basal ration + Boiled water + 0.1 gr / day Antibiotic Monensin in 1 liter of water; P2: Basal ration + Boiled water + 0.5 gr / day Antibiotic Monensin in 1 liter of water; P3: Basal ration + Boiled water + 1 gram / day Antibiotic Monensin in 1 liter of water. Data analysis used ANOVA one way variance and continued with the Least Significant Difference Test (LSD) with a confidence level of 5%. The results of the study by giving various concentrations of monensin antibiotics to broilers had significantly affected ration conversion, drinking water consumption and final weight. The administration of 1 gram monensin antibiotic concentration tends to be better for ration consumption, body weight gain, drinking water consumption and final weight of broiler chickens compared to lower concentrations or controls.

Endodontic Retreatment

Context: Use of root canal solvents has increased the success rate of endodontic retreatment and it has made the procedure faster and simpler. Aims: During retreatment, a solvent facilitates the removal of obturation material and root canal sealer by softening it, so as to obtain a root canal free of debris and microorganisms. Hence an invitro study was done to evaluate and compare the dissolving effect of RC Solve, Eucalyptus oil and G-sol on AH Plus Root Canal Sealer. Methods and Material: Thirty standardized stainless-steel rings filled with AH Plus sealer manipulated according to manufacturers instructions were prepared and placed ten minutes for complete setting in an incubator at 37°C for 48 hours and weighed to obtain the initial weight. The samples were divided into three equal groups of 10 each and immersed in RC Solve, Eucalyptus oil and G-sol for 10 minutes and dried in an incubator at 37°C for 24 hours and weighed again for final weight. The amount of sealer lost was determined by calculating the difference between initial and final weight. Results: The dissolving effect of AH Plus sealer on all three solvents showed a marked amount of weight loss (p<0.05). The best dissolving capability on AH Plus sealer was exhibited by Eucalyptus oil followed by RC Solve and least for G-Sol. The result of the ANOVA with a p-value of 0.004 indicated a significant difference of weight change of AH Plus sealer after immersion into RC Solve, Eucalyptus Oil and G-Sol. Conclusions: Based on the findings of this study, it was concluded that Eucalyptus oil has a slightly better solvent effect.
