No results found.During the year of the author's assignment at the Bhairawa Fishery Development Centre about 1 117 000 fingerlings were produced; this is the highest figure obtained. Unfortunately, the water supply was insufficient; otherwise the production of fish fingerlings would have been higher. With regard to integrated fish culture farming, demonstrations of fish-cum-pig and fish-cum-duck culture were set up at the Government fish farm. The results were good, the fish production ranging from 1 845.56 to 2 443.34 kg/ha/yr. At present farmers show great interest in these activities. Previously, integrated fish farming was not accepted by them due to high capital investment and lack of experience. However, guidance in this respect was given to the farmers during in-service training conducted by the project. After participating in the training courses many have started farming fish integrated with livestock. In Pokhara, the work mainly involved cage fish culture; the number of cage owners increase d from 13 in 1978 to 63 in 1979. The boatbuilding activities have also progressed well. The number of boats built increased from 51 in 1978 to 63 in 1979. Through in-service training, cage owners from various lakes were instructed in cage fish culture, and 16 US volunteers and 61 farmers from the villages around Bhairawa were trained in various aspects of fish culture. -

No results found.Duck raising and fish-cum-duck farming are part of the Integrated Fishery and Fish Culture Development Project in Nepal. Improved strains of ducks have been introduced into the country and their production commercially and by the rural population is increasing rapidly, in turn increasing the demand for ducklings from the Government Fisheries Development Centres. Observations were made at the three centres and recommendations were made for improvements to present practices to increase productio n of duck eggs and ducklings. Training in duck husbandry was also given to technicians currently involved in this field. This report contains detailed information, with illustrations, of improved types of duck housing facilities, using mostly local materials, and procedures for selection, care and management of eggs, ducklings and breeding ducks and their distribution. Advantages and comparative costs of different breeds of ducks are analysed and introduction of an additional breed of duck i s suggested. Centralized locations for breeding and distribution of ducklings is recommended and the facilities needed are described. Financial and technical assistance is recommended to encourage the private sector to enter into duckling or meat-duck production on a small commercial scale. Other schemes for commercial duck raising are described and costs are given for buildings, feeding and other requirements. The appendixes list feeding requirements and costs of egg, duckling and meat-duck pro duction, as well as cost of facilities. -

Also available in:
No results found.Work carried out on the culture of fish in cages in Nepal, the introduction of the practice to private fishermen by the project and its technical and economic aspects are described in this report. A variety of cages were tried, their relative advantages and disadvantages and costs are provided. The species tried were mainly silver carp and grass carp and they have proved to be economical because of the relatively low or negligible feed costs involved. Rohu and common carp yield additional inci dental production when stocked in small numbers with the above species. Preliminary experiments on the culture of bighead carp in cages have also been very encouraging. An explanation for different growth rates observed of planktivorous species in the three lakes of the Pokhara Valley is provided on the basis of limnological data and qualitative and quantitative studies of plankton, as well as stomach content studies. The economics of cage culture with these species is discussed. The results are compared with those obtained with other species in other countries. Suggestions are provided for future work, including variations of stocking densities. The possible initial increase in fish production in the Pokhara Valley through cagefish culture is indicated. Recommendations for the future are also provided.
