Synopsis (short abstract) It is estimated that per year in Barbados, 585 tonnes of fish waste are generated at the two main public fish markets, and 936 tonnes of waste are generated at private fish processors across the island. Therefore, Barbados produces an aggregate of 1 521 tonnes of fish waste annually. At present, approximately 90 percent of fish waste and by-products are discarded at the landfill. To produce fish silage on a large scale in Barbados the baseline cost (based on a 90 percent yield rate) is estimated to be USD 265 920, excluding the cost of fish waste and acids. Sales revenues based on competitor prices range from USD 528 485 to USD 2 044 900. During the fish silage demonstration workshop held from 23 to 26 July 2019 in Bridgetown, the cost of small-scale production (100 kg) was estimated to be USD 900 and USD 254 when using the chemical and biological methods, respectively. The existing regulatory framework has the potential to facilitate the production and utilization of fish silage. However, clearance and permission may have to be institutionalized in order for fish silage to be produced and utilized in, and or as, animal feed. These conclusive findings subsequently prompted FAO to engage in a partnership with the Caribbean Agriculture Research and Development Institute (CARDI), to develop the silage-based feeds and document their effects on the growth performance of select animals.

    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.

    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.

    The Manual of Food Portion Quantification; Saint Kitts and Nevis was developed to assist individuals in recognizing and reporting their food and beverage intakes accurately during the National Individual Food Consumption Survey in SKN conducted in 2020. The Manual was designed to be used along with the 24-hour Dietary Recall Method, which was designed to assess the food consumption of individuals aged 18 to 65 years old. Additionally, it is expected that this Manual can be used in nutrition education programs to demonstrate the importance of adequate portion sizes in obesity control and the prevention, waste minimization and management of food cost. The Manual would also be a useful guide for ordering and preparing food and meeting nutrition needs of the population of SKN, as well as the citizens of the other Caribbean countries. The Manual includes 121 photos of single foods and recipes, as well as household measurements (e.g. cups, spoons), of which 85 were taken in SKN and 36 were taken in Brazil. All photos were taken using a similar methodology. The photos cover the measurement of most food groups, either by photos of portions or of household measurements. The weight of every portion in each photo and the volume of all utensils were recorded and are available at the end of the Manual.
