Synopsis (short abstract) This publication is a practical manual that will guide the reader through the main principles of producing fish silage by fermentation and explain each step of the fermentation process needed to successfully become a fish silage producer. Fish, including shellfish, are highly nutritious and in much demand all over the world. However, fish processing by-products, in particular viscera (guts), are highly perishable. If not preserved or processed within a relatively short time after harvest, they may deteriorate rapidly making them unfit for human consumption or other uses. In many cases, processing leads to the removal of significant parts of the fish, such as the viscera, head, belly flaps and backbone. Depending on the species, these parts may represent between 30 percent and 70 percent of the fish. Some parts, such as gonads, belly flaps and backbones, may be used directly for human consumption, but most of the by-products of fish processing have traditionally been wasted, leading to negative environmental impacts, or they have been used in fresh form as feed for livestock or as fertilizers.

    Silage making in the tropics with particular emphasis on smallholders 2001
    Also available in:
    Silage making has always been an integral component of temperate feeding systems worldwide, as a means to ensure year-round feed supply for high production animals. However, its use in the tropics has been restricted to isolated cases, usually involving higher-return enterprises and, in particular, the dairy industry. What are the reasons for its apparent lack of application in the tropics? The paper "Silage making in the tropics with particular emphasis on smallholders" documents the proceeding s of an electronic conference that examined both this question and the various aspects of silage making in the tropics. Specifically, it reviews the potential for use of tropical silage for livestock production, with special reference to the smallholder situation.

    Production and utilization of fish silage
    A manual on how to turn fish waste into profit and a valuable feed ingredient or fertilizer
    2018
    Also 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.
