Trial was conducted into two consecutive phases, the first was fry (4-5 days old)administration with negative control (without hormone) and positive control (with hormone) feed viz., MT1:60mg/kg, MT2:70mg/kg (17α-MT), carp testis CT1:70% and CT2:80% for 30 days to reverse the sex of male fish and the second phase was nursing the fingerlings for two months on control diet (32% Crude protein).Results revealed a significant growth rate (P<0.05) in the control group where final weight (4.8±0.34ab) and weight gained was recorded as 0.66±0.03ac. In proximate chemical composition of body meat, CT2 treatment showed maximum retention of crude protein, crude fat, and ash whereas dry matter showed maximum retention in MT2 and CT1 treatments. Morphological and histological examination revealed significant d...

Fish maintained on 32% crude protein, conventional basal feed was supplemented with Fe & Fe2O3 nanoparticles (each at 0.6 & 0.8 mg/kg supplementation levels) to replicate groups of fish for 90 days. Morphometric characteristics i.e. wet body weight (g) and body length (cm) was recorded fortnightly. It was found that the weight gain, body length, SGR and PER were significantly improved in the fish fed on nano iron oxide supplemented diet (T2). Protein and lipid nutrients retention in the body meat was improved in group of fish fed with nano iron supplemented diet (T3). A significant increase in hemoglobin (Hb) content, red blood cell (RBC) count, white blood cell count (WBC) and hematocrit (Ht) value was noticed throughout the study period when compared to control group.

Present trial was conducted with the aim to produce male common carp (Cyprinus carpio) by egg immersion technique. Through this little insight, the effect of different hormone concentrations (17α-methyltestosterone @ HC:150, 300, 450 and 600 µgl-1) with immersion times (IT: 24, 48 and 72 hrs) and their interaction effect (HC x IT) on the hatching percentage of Cyprinus carpio eggs, percent survival and percent of male’s production was evaluated specifically. Results showed that egg hatching percentage decreased with increased IT likewise, survival of treated fry was affected by increasing the IT (P<0.001). The main interaction effect of HC x IT showed that the highest percent of male individuals (95%) was obtained at 450-600 µgl-1 HC for 72 hrs IT, followed by 88-92.50% at 150-300 µ...

One control (T1) and five experimental diets (T2, T3, T4, T5, T6) were prepared by using gelatinized and non-gelatinized corn with the combination of various levels (0.0, 0.6, and 0.8 mg/kg) of CrCl3H12O6. After acclimatization with a control diet (T1) (32% CP), twenty fingerlings of these species were randomly stocked in eighteen digestibility tanks, each with one replicate. At the end of the trial, results showed that gelatinized corn with chromium supplementation significantly enhanced (P<0.05) digestibility of nutrients and enzyme activities (amylase and protease) in liver and gut in all treated groups. Crude protein (76.05±0.54), crude lipid (84.53±0.46), carbohydrate (69.15±2.19), and gross energy (76.92±0.74) showed the h...

Six experimental diets were prepared by using different levels of chromium chloride hexahydrate (0, 0.2, 0.4 mg/kg, each with G & NG corn). For this experimental trial, 480 fingerlings, irrespective of sex were distributed in six aquariums each with replicate. Results revealed that gelatinized corn along with increasing level of Cr2Cl3.6H2O have a positive impact upon body composition of fish. Hematology was positively correlated with chromium chloride hexahydrate supplementation in gelatinized corn. Amylase gut enzyme also showed significant (P<0.05) increase in group fed with chromium chloride hexahydrate supplemented diet (G corn). However, corn with chromium chloride hexahydrate supplementation did not revealed any significant impact on gut protease enzyme activity. From these resul...

Among both fields, total 4547 specimens were collected during entire sampling and maximum population was recorded from fruiter orchards 68.24% (N = 3103) and least population was recorded from lemon orchards i.e. 31.76%. Wherein in case of lemon orchard, maximum population was recorded during 6 sampling (350 ± 145.38) and least as well as equal values were recorded during 1, 2 and 7 sampling (69 ± 53.32). Whereas, species abundance was recorded utmost and equal during 4 and 9 sampling (32 species) at temperature and humidity of 29.2°C and 31.5% and 35°C and 58%, respectively. However, least species abundance was recorded during 1 sampling i.e. 17 species at 29oC (temperature) and 37% (humidity).

Using various levels of chromium chloride hexahydrate six test diets designated as T1 (G/0.0 Cr2Cl3.6H2O mg Kg-1), T2 (NG/0.0 Cr2Cl3.6H2O mg Kg-1), T3 (G/0.2 Cr2Cl3.6H2O mg Kg-1), T4 (NG/0.2 Cr2Cl3.6H2O mg Kg-1), T5 (G/0.4 Cr2Cl3.6H2O mg Kg-1) and T6 (NG/0.4 Cr2Cl3.6H2O mg Kg-1) were prepared. Results showed highest apparent digestibility coefficient (ADC) of nutrients dry matter, crude lipid and gross energy in test diet T5 that was gelatinized and supplemented with chromium 0.4 mg/Kg while, for crude protein higher value of nutrient digestibility was recorded in T3 test diet (G/0.2 Cr2Cl3.6H2O mg/Kg). It was concluded that chromium supplementation with gelatinized corn in fish (Cirrhinus mrigala) diet can improve the nutrients digestibility more efficiently.
