| dc.description | In aquaculture it is necessary to look for food alternatives for fish in confinement, which helps reduce production costs and therefore increases the economic benefits of fish farmers. Aquaculture nutrition faces a challenge, to implement other protein sources of plant origin with greater availability and low cost. In the studies carried out by various authors that are cited in this work. It is observed that they achieved excellent results in biological silage diets from fish residues. A diet including 30% biological silage from fish residues (To obtain silage, viscera and residues resulting from filleting were fermented by adding an inoculum of lactic acid bacteria (commercial yoghurt) and 20% cassava flour as a carbon source, presented significantly higher weight gain, size increase and feed conversion compared to the treatments evaluated, probably related to the high levels of polyunsaturated fatty acids Perea et al (2018) Other alternative ingredients used in fish farming include proteins and vegetable oils, agro-industrial by-products, aquatic plants such as Lemna and azolla, as well as vegetable protein of unicellular origin such as antibiotics and prebiotics; Llanes and Toledo 2017, refer to products and by-products of animal origin such as silage, earthworm and excreta, by-products transformed animals and fermented yeasts, as stated by González et al. l. (2017). | es_ES |

| dc.description.abstract | En la acuicultura es necesario buscar alternativas alimenticias para los peces en confinamiento, lo cual ayuda a reducir los costos de producción y por consiguiente aumenta los beneficios económicos de los piscicultores. La nutrición acuícola tiene ante sí un reto, implementar otras fuentes proteicas de origen vegetal con mayor disponibilidad y bajo costo. En los estudios realizados por diversos autores que se encuentran citados en este trabajo. Se observa que lograron excelentes resultados en dietas de ensilaje biológico de residuos de peces. Una dieta con inclusión del 30% de ensilaje biológico de residuos de pescado (Para la obtención de ensilaje, fermentaron vísceras y residuos resultantes del fileteado adicionándole un inóculo de bacterias lácticas (yogurt comercial) y 20% de harina de yuca como fuente de carbono, presentó ganancia de peso, incremento en talla y conversión alimenticia significativamente mayor con respecto a los tratamientos evaluados, relacionado probablemente a los altos niveles de ácidos grasos poliinsaturados. Perea et al. (2018). Otros ingredientes alternativos utilizados en la cría de peces incluyen proteínas y aceites vegetales, subproductos agroindustriales, plantas acuáticas como Lemna y azolla, así también proteína vegetal de origen unicelular como antibióticos y prebióticos; Llanes y Toledo 2017, hacen referencia a productos y subproductos de origen animal como ensilados, lombriz de tierra y excretas, subproductos animales transformados y levaduras fermentadas, como lo manifiesta González et al. (2017). | es_ES |
