This cage-fish culture which is family owned was started to assist the people who were displaced by the construction of Khulekhani reservoir for the purpose of hydroelectricity generation. In the initial period of the project, the government of Nepal provided technical assistance as well as financial support to project beneficiaries. The program is still ongoing whereas only technical assistant is provided. Fish species used for in the project are Silver and Bighead carps. Cage management is represented by the continuous removal of fouling as well as the maintenance of cages. Productivity is about 6 kg/m3 of water volume after 8-9 months of growth without feeding.

This presentation addresses the management of fish hatcheries starting with some information on fish reproduction in general. Before addressing artificial reproduction, natural collection of wild fry or post larvae have been covered. The presentation includes sexual maturation and broodstock management including maintenance and replacement. Examples and hatchery technologies and so requirements have been included. Various shages and pracices have been included starting by spawning till fry nursing passing by fertilization, incubation and hatching. Enhancing hatchery productivity through the manupulation of temperature and/or light as well as the production of mixed sizes of hatchery products have been addressed.

La foto corresponde a un estanques de produccion de tilapia roja, (Densidad de cosecha 4ind/m2, Tasa de conversiòn aprox 1,4:1, temperatura del aguau todo el año 25 – 32 ºC) alimentada con pienso ó balanceado, pero ademas se le a permitido que el espejo de agua este cubuierto un 40% con la planta acuatica conocida como AZOLLA. Esto para permitir mantener la produccion y pero evaluando los costos por alimentaciòn dado, al suministrar algo de productividad primaria.
