The shortage of marine resources calls for the implementation of new technological processes for providing a better utilization of waste and by-products from fisheries and fish processing activities. Most of these by-products are currently used as raw materials for animal feed. It is estimated that their utilization in human foodstuffs, nutraceuticals, pharmacy, or cosmetics would increase their value fivefold. This book discusses the opportunities for upgrading these materials by means of basic technologies such as hydrolysis, membrane ultrafiltration, and better handling techniques.

This guide explains how to transform fish waste into feed for livestock or fertilizer for crops by using fish silage technology. It discusses the fundamentals of fish silage production as well as equipment needed, storage and useful applications

A significant amount of fish by-products is produced during fish processing. These by-products represent 20–80 percent of the fish and provide a good source of macro- and micronutrients. Yet they often go unutilized, when they can easily be converted into a variety of products including fishmeal and oil, fish hydrolysates, fish collagen, fish sauce, fish biodiesel and fish leather. The production of fish silage using organic acid is a good example of the simple and inexpensive conversion processes which can be employed. Fish silage production uses minced by-products or minced whole fish unsuitable for human consumption as raw material, before adding a preservative to stabilize the mixture – usually an organic acid such as formic acid. The process breaks down protein into free amino acids and small-chain peptides which have nutritional and antimicrobial properties, therefore, the fish silage can be used as healthy feed and fertilizer.The feasibility studies on fish waste management in Bangladesh, Philippines and Thailand outline existing good practices on the utilization of by-products and fish waste. Furthermore, the insights provided on the potential production and utilization of fish silage in each country are promising in terms of increasing the productivity of the fisheries sector, reducing post-harvest waste, increasing economic value and improving environment sustainability.

Part of the new IFST Advances in Food Science Series, Seafood Processing: Technology, Quality and Safety covers the whole range of current processes which are applied to seafood, as well as quality and safety aspects. The first part of the book (‘Processing Technologies’) covers primary processing, heating, chilling, freezing, irradiation, traditional preservation methods (salting, drying, smoking, fermentation, etc), frozen surimi and packaging. The subjects of waste management and sustainability issues of fish processing are also covered. In the second part (‘Quality and Safety Issues’), quality and safety analysis, fish and seafood authenticity and risk assessment are included.
