Fish waste: Valorisation methods on a local scale

Abstract

Abstract Fish waste management is being neglected in most parts of the world. Unfortunately, with the worldwide increase of demand, this has generated many environmental impacts. This negligence can be traced to the ridicule of the value of this resource as well as the many difficulties related to its valorization. This work suggests the most efficient methods to valorize fish waste using biological and ecological means. With minimal investments so that they can easily be adopted by local farmers and landowners. These methods can either use bacterial action such as composting to create bio-fertilizer, ensilage to manufacture liquid silage or lastly, the production of fish feed to minimize the cost and the detrimental effects of fish farming.
