Fish are members of paraphyletic group of an organism that consist of all gills bearing aquatic carniates which lacks limbs with digits. Fish are considered as an important natural food resource, worldwide specially that of animal protein. Fishes are considered auspicious and symbolize as sign of fertility, power and prosperity in Nepal. There are about 185 fish species in Nepal belonging to 79 genera, 31 families and 11 orders (Shrestha. J.2001). 232 species of Fishes are found in Nepal (Shrestha T.K 2008). Among them 217 species are Indigenous and 15 species are exotic. The rivers of Nepal are really rich in fish fauna which need to be explored scientifically (shrestha. J.N.2001).
My study will deals with fish species present in kankai river of Jhapa district, which is largest and holiest river of jhapa district originated from george of mountains, flowing southward to low land of east terain. My research objective is to study the diversity of fish species in kankai River. To study the fish resources in kankai River, the condition of water will analyze with the help of water analysis kit. The fish will be collected with the help of local fishermen. The collected fish will be analyze in Tri-Chandra Multiple Campus Lab.

Power point presentation in Fish diversity in Kankai river Jhapa district, Nepal

  1. 1. FISH DIVERSITY IN KANKAI RIVER OF JHAPA DISTRICT,EASTERN NEPAL Umesh Acharya Roll no: 477 Batch: 2071-2075 Department of zoology Tri-Chandra Multiple Campus Kathmandu, Nepal Supervisor: Prof. Dr. Geeta Sharma Acharya Co-supervisor: Om H. Shrestha (Asst.
  2. 2. INTRODUCTION  Nepal is rich in natural water resources, contains more than 6000 river and streams(Gubhaju, 2011).  Fish occupy almost all major aquatic habitats of Nepal.  Extreme varied topography of Nepal, generates a wide variety of aquatic habitats, yields a rich diversity of fishes (Rajbanshi 2005).  The distribution and ecology of fishes are remains to study in many Asian countries (Dudgeon 1999).
  3. 3.  Shrestha,J.(2001) recorded 182 indigenous fish species from Nepal. Rajbanshi (2005) prepared a checklist from the published literature and reported 187 species, Shrestha,T.K.(2008) recorded 217 indegenous fish species from Nepal.  The aquatic lives of the precious water resources of the nation are mostly threatened when compared with other ecosystems (Rai,2008).
  4. 4.  High diversity fishes in the rivers of Nepal calls for concerted efforts to preserve them for posterity.  The native fish decline is associated with poor knowledge, priority, investment; and water quantity and quality (Shrestha, 2011; Gurung & Baidya,2012).  The knowledge on fish taxonomy and identification is highly desirable to state unrecorded new native fishes before they might peril and become extinct.
  5. 5. OBJECTIVE  To explore the diversity of fish fauna of Kankai River of Jhapa district of eastern Nepal.
  6. 6. SIGNIFICANCE OF THE STUDY  The rivers of Nepal are really rich in fish fauna which need to be explored scientifically and conserved them (J.N Shrestha, 2016).  The exploitation of Nepalese native fishes is increasing enormously.  Some of the important threats of Nepalese native fishes are; over fishing, pollution, alteration of natural habitats and poor understanding of fish diversity and ecology.  Therefore, my research significance is to obtain knowledge about fish diversity of kankai River to overcome knowledge gaps, It will contribute to biodiversity profile of fish diversity of Nepal

  8. 8. MATERIALS AND METHODS Materials required  Formalin(8% and 40%)  Plastic jars  Cast Net  Fishing rods  Portable water analysis kit Photo world.comCast net Fishing rods Portable water analysis Clipatrix.com
  9. 9. METHODS  Fish sampling sites (3-5 based on abundance of fishes in particular area) in the Kankai River will be selected.  Portable water analysis kit will be used to analyze water temperature, dissolve oxygen, pH, CO2, and water velocity of the sampling sites.  Fishes from each fishing site will be collected with the help of local fishermen by cast net and local tools for 9 months.
  10. 10.  The collected fishes, will be preserved in formalin(8%to 40%) making their head upside down so as to protect the caudal fin.  Fish will be analyzed in the lab of Trichandra- Multiple Campus, Department of zoology.  They will be identified using standard method of K.C.Jayaram (1999) and Shrestha (2001, 2008). Fishes preserving in formalin
  11. 11. EXPECTED OUTCOMES  The number of fish species found in Kankai River of Jhapa district will be identified. It will contribute to the biodiversity profile of fish diversity of Nepal.
