Book (stand-alone)Production and utilization of fish silage
A manual on how to turn fish waste into profit and a valuable feed ingredient or fertilizer
2018Also available in:
The processing of fish leads to a significant removal of parts of the fish, such as heads, bones, guts, etc., these parts can represent between 30-70% of the fish. The fish silage process transforms fish waste into a liquid mix of hydrolysed proteins, lipids, minerals and other nutrients, easily digestible by both terrestrial and aquatic animals. It can also serve as an excellent fertilizer. Fish silage could make a difference in terms of; i) environmental impact - by reducing levels of waste, ii) animal health - by providing nutrients and bioactive components, iii) economic gains - as waste is converted into a valuable product that can replace expensive feed ingredients, or be used as a fertilizer. This manual will provide technical guidance and explain each step and main principles of production and utilization of fish silage. -

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.
