    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.

    Although the total traditional marine catches have reached a plateau or started to decline, there has been a steady grouth in both marine and freshwater aquaculture. Intense commercial fishing pressure has forced governments world-wide to reconsider total allowable catch limits and in some instances to place a moratorium on certain species. This trend has enhanced the relative importance of aquaculture activities and many commercial companies find it profitable to invest in aquaculture because o f the many advantages which are offered including control of broodstock., ability to harvest any given size at any given time, and the ability to grow fish in close proximity to processing facilities. In addition, total quality management is possible thoughout the entire process from the hatchery to the dinner plate. In developing countries, aquaculture provides nutrition for the domestic market and generates foreign capital from the export market as well as employment for workers on fish farms and processing plants. However aquaculture is not without its difficulties. There are communicable diseases including fungi, bacteria, viruses and parasites which are always a threat to aquaculture species due to the high stocking densities which are often used in the industry. In addition, as the industry grows, disposal and/or utilization of processing waste is a growing problemor perhaps an apportunity which has yet to be exploited. The present document was prepared at the request o f FAO to review the existing literature on procedures for the treatment of aquaculture waste and present methods of aquaculture waste utilization. In addition, the document deals with potential pathways of major pathogen transfer to wild and cultured aquatic species though the wate from processing facilities. The document presents an evaluation of potential hazards and risks of pathogen transfer to aquaculture systems though animal and animal processing waste disposal and reuse.
