Aprovechamiento de subproductos del cultivo de trucha arcoíris (Oncorhynchus mykiss) como estrategia de sostenibilidad ambiental en la piscicultura

Abstract

The fishing industry represents one of the most important economic sectors in the world, where in Colombia rainbow trout fish crops represent a large part of the fish meat production in the country, with great contributions to the food security and economy of many populations. This economic activity has several processes and production stages for the production of products for the market, within which there is evidence of a continuous production of organic by-products that are not used and can generate negative impacts on the environment. This project aims to take advantage of the by-products of rainbow trout (Oncorhynchus mykiss) farming as an environmental sustainability strategy in fish farming, by preparing a balanced cat food, identifying its potential for use and evaluating its nutritional composition. This research has a mixed methodological approach based on a bibliometric review and determine a process of transformation of the by-products experimentally, where through processes of enzymatic hydrolysis with papain, cooking, dehydration, grinding and compaction, a balanced food with high . levels of protein and nutritional elements capable of complying with the regulatory parameters for feeding cats, in addition, with the Soxhlet methodology, oil extraction was carried out from the by-products (heads, spines, viscera and gills), obtaining different types of fatty acids and values of Omega 3-6 and 9, where it can be concluded that the byproducts have great potential for the development of cat food and, in addition, a wide range of possibilities for being applied in the feeding of animals in the agricultural and domestic sectors, contributing to the environmental sustainability of the fish farming sector and generating a strategy to reduce organic waste in the environment.
