Alternativas alimenticias para la trucha arcoíris (Oncorhynchus Mykiss) en la serranía ecuatoriana

Abstract

The objective of the present research was to study the nutritional alternatives in the Ecuadorian Highlands for trout breeding, in juvenile and fattening stages. The search for bibliographic information was based on the compilation of research from the following scientific journals: Scholar, Redalyc, Refseek, Springer Link, Scielo, Dialnet, Academia.edu, Basearch.net, High Beam.com, Scopus, E-libro, Experimental Thesis, scientific articles from Latin America and the country. The researched variables were weight (g), length (cm), mortality (%) and economic evaluation (C/B). So that for the registration of the appropriate data for the investigation, tables and graphs were used which significantly boosted their comparison and therefore the formulation and interpretation of the best resulting option. In the evaluation of fingerlings, the best results were obtained with the use of 5% dehydrated bovine blood with a C/B of $3.10, in juveniles the 50% viscera 50% worms used, have a C/B of $1.25, in the stage of fattening the 3.5% red pepper meal used has a cost/benefit of $1.56, therefore it was concluded as the food alternatives that favored weight, length, mortality and cost/benefit, obtaining a better development. Thus, it is recommended the study of the new food alternatives that achieve sustainability in production.
