Gavialis Gangeticus

A study on helminth parasites on captive gharial (Gavialis gangeticus) was conducted during July-December 2012 at Gharial Breeding Centre, Kasara, Chitwan National Park to isolate, identify and find out their prevalence. Dead gharial hatchlings were collected directly from the centre in fresh and frozen conditions. Out of 85 samples   examined, 40 samples 47.06% as prevalence rate of helminth parasites. During the study three helminth parasites were first reported from the gharials of Nepal; Pentastomid (Sebekia sp.), Capillarioids and Ascaridoids. The dead hatchlings were found to be infected with Pentastomid (41.17%), Ascaridoids (7.05%), Capillarioids (1.17%), Proctocaecum gairhei (3.52%) and Exotidendrium sp. (36.47%). In the month of December helminth parasites showed highest prevalence; Sebekia sp. (100%) and Proctocaecum gairhei (75%) and Exotidendrium sp. (100%) and the lowest prevalence in the month of July; Sebekia sp. (4%), Capillarioids (4%) and Exotidendrium sp. (8%).DOI: http://dx.doi.org/njst.v15i2.12111Nepal Journal of Science and Technology Vol. 15, No.2 (2014) 37-40

Gavialis Gangeticus

This study was carried out to investigate the habitats and abundance of the Gharials in Narayani river of Chitwan National Park from 2012 to 2013. A total of 38 Gharials including 3 hatchlings, 8 juveniles, 12 sub-adults and 15 adults were recorded during the study period. Only one breeding male was observed reflecting the critical condition for the breeding in the wild within Chitwan National Park. The abundance of the gharial was restricted in 2 areas, namely Khoria muhan and Velaunji due to suitability of the habitat conditions and minimum human disturbances. The Basking activities in relation to depth showed that > 80 % of the Gharials selected sandy banks. Among the 2 populations, the gharials in Khoria muhan preferred shallow to moderate depth of water because of presence of braided channels in the area. In contrast, the Gharials in Velaunji select deep water course of the main channel. The park management must adopt conservation measures such as ban of fishing and regular monitoring of habitats and population to maintain long term conservation of gharials in Narayani river.J. Nat.

Gavialis Gangeticus

Gharials Gavialis gangeticus have been reared in ex situ facilities in the Gharial Conservation and Breeding Center (GCBC) in Chitwan National Park of Nepal since the 1980s.  There remains a paucity of detailed information concerning their growth rates, particularly with respect to season.  We randomly selected 20 gharials (45 months old) in the GCBC, tagged them, and recorded total length (TL) and weight over three warm (April–September) and two cold (October–March) seasons between 01 April 2013 and 30 September 2015.  We also recorded amounts of fish consumed by these gharials every month over the 30-month period.  On average per season, the gharials grew by 9.48±3.63 cm (1.58cm/month) in length and gained 2.61±1.14 kg (0.43kg/month).  Growth rates were significantly higher during warm seasons.  The highest increase in both length (mean= 21.2±8.61 cm) and weight (mean =5.59±2.12 kg) occurred during the first warm season (April 2013–September 2013) of the study, and annual growth rate was also highest during the first year.  Our data indicated strong correlation between mean length and body weight.  A total of 2,103.9kg fish was consumed by 20 gharials over 30 months, for a mean consumption of 3.5kg fish per individual per month.  Mean fish consumption was also significantly higher during warm (96.99±37.35 kg) versus cold (29.83±17.09 kg) seasons.  Survival rate was 100%.  Our findings establish baseline data for growth and feeding rates of captive gharials that will be useful in making management decisions in captive breeding and rearing facilities.

The Fishing Cat is a highly specialized and threatened felid, and its status is poorly known in the Terai region of Nepal.  Systematic camera-trap surveys, comprising 868 camera-trap days in four survey blocks of 40km2 in Rapti, Reu and Narayani river floodplains of Chitwan National Park, were used to determine the distribution and habitat characteristics of this species.  A total of 19 photographs of five individual cats were recorded at three locations in six independent events.  Eleven camera-trap records obtained during surveys in 2010, 2012 and 2013 were used to map the species distribution inside Chitwan National Park and its buffer zone.  Habitat characteristics were described at six locations where cats were photographed.  The majority of records were obtained in tall grassland surrounding oxbow lakes and riverbanks.  Wetland shrinkage, prey (fish) depletion in natural wetlands and persecution threaten species persistence.  Wetland restoration, reducing human pressure and increasing fish densities in the wetlands, provision of compensation for loss from Fishing Cats and awareness programs should be conducted to ensure their survival.  We also recommend studying genetic diversity of sub-populations, as well as habitat use by radio-tagging.

The Greater One-horned Rhinoceros (Rhinoceros unicornis) is found almost exclusively in Nepal and North-Eastern India. There have beenonly a few studies made on the food and the nutrient compositions of fodder species preferred by The Greater One- horned Rhinoceros. Thepresent study identifies the nutrient content of the fodder species consumed by One-horned rhinoceros which would be helpful to develop proper strategies for rhinoceros food management. For this altogether 8 grass species which were most preferred by rhinoceros were collected from Chitwan National Park. Systematic sampling was applied for sample collection and collected samples were taken to the Animal Nutrition Laboratory, Khumaltar for nutrient analysis. Among all the collected species the highest OM% was seen in Faank (93.98 ± 0.88) while Ash% and CP% was found to be highest in Eragrastic Tenella (13.67 ± 2.92) and Phragmatic karka (11.94 ± 2.26) respectively. Lowest NDF% was again seen in Eragrastic tenella (76.76 ± 2.93) and lowest ADF% and ADL% were found in Mala dubo with mean values (43.50 ± 6.86) and (6.41 ± 2.16) respectively showing high digestibility of these grasses. There were only slight variation in the EE% of the grass species withhighest mean value of (3.702 ± 1.73) of Imperata cylindrical to lowest mean value of (1.722 ± 0.11) of Eragrastic tenella. Highest energy was found in Faank (4181.90 ±1.10) and Calcium content was seen highest in Cynodon dactylon (1.30 ± 0.83).DOI: http://dx.doi.org/10.3126/ijasbt.v2i4.11119 Int J Appl Sci Biotechnol, Vol. 2(4): 402-408

A one-year study conducted to ascertain the prevalence and risk factors associated with helminth infection in Hangul Deer Cervus hanglu hanglu at Dachigam National Park revealed that 40.45% (89 of 220 samples) were infected with four helminth species including Heamonchus contortus, Trichuris ovis, Dictyocaulus viviparus, and Moneizia expansa.  The study signified that the infection was more prevalent during the dry season (summer and autumn) as compared to the wet season (winter and spring).  The overall prevalence of Heamonchus contortus was the highest (23.18%) followed by Trichuris ovis (8.18%), followed by Dictyocaulus viviparus (5.45%), and Moneizia expansa (3.63%).  The present study should be of importance in conserving the erstwhile state animal, listed as Critically Engendered in 2017 by IUCN.
