Synopsis (short abstract) Construction of commercial fish farms and fish hatcheries and advice and training in their management are described in this report, along with details of valuable experience gained during the work on the project. Advice and assistance were provided for the introduction of new fish species for culture and for the introduction of the duck-cum-fish culture. Fish propagation techniques were adapted and introduced and training provided in this field. New fish egg incubation and larvae-rearing devic es were developed and installed. Advice, based on the expert's investigations, was provided for expanding the possibilities of fish production. The expert estimated the total fish catch in the country for statistical purposes. Efforts should be expanded to promote the mass production and distribution of fingerlings of the cultivated fishes, in conjunction with broadened training and demonstration work. Additional new hatchery-farms for fingerling production would promote fish culture developme nt. Fish culture should be further expanded through use of village tanks and reservoirs for intensive culture, assistance to farmers in fish pond construction, extension of fish-cum-duck culture and paddy-cum-fish culture, restocking of lakes and rivers and conducting of basic research.

    This document is Report FAO Expanded Program of Technical Assistance No. 1818. For convenience in classifying information on fisheries, EPTA reports produced by the FAO Fisheries Division since 1 January 1962 are also numbered consecutively in a sub­-series with the general series. This is the fortysixth report in the sub-series: FAO Fish.EPTA Rep. (Fib/EPTA 46).

    Animal protein deficiencies are wide-spread in both rural and urban Iran. One means of increasing low-cost protein foods is the production of fish. The Caspian Sea and the Persian Gulf are at present the main sources of fresh fish, but the catches of such favoured inland fishes as the whitefish and souf have declined to very low levels. Development of inland fisheries can provide much of the needed protein. To do this there is need to investigate the possibilities of fish culture and manageme nt of inland waters. Trained personnel are needed and a fish culture training and research centre could provide this personnel. In this project, a search was made in the Caspian plains, the Tabriz, Isfahan, and Shiraz areas for sites where fish cultural stations, village fish ponds, and large community ponds could be built. The report contains descriptions of these sites, and the results of water analyses of their water supplies. The Iranian trout and Caspian “salmon” programme is reviewed and suggestions made for its development. At present, there are no rice fields in either the Caspian plains or the Persian Gulf area used for the protection of fish. In the Caspian area, only one crop of rice is grown annually and after the harvest in late August and early September the fields remain idle until the spring plantings areas were selected near Amol where demonstration rice fields culture could be undertaken. Some information is presented on the investigations of inland, fresh waters and water quality control. The need for a single Department of Fisheries to obtain a coordinated programme for the development and management of the inland waters of Iran is indicated.

    Limnology and fisheries biology of the waters of Pokhara Valley, Nepal: implications for fisheries and fish culture 1978
    Also available in:

    To assist in management of the fisheries and help increase the fish production from the Pokhara Valley in Nepal, data were collected on limnology, fish biology and present fish catches. A field laboratory was established. Counterpart staff and assistants were trained. Recommendations include continuing monitoring of water quality and fish catches, improvement of the fishing gear licence system, limitation of fish stocking and some regulation of fishing gear.
