Diseño y optimización de herramientas (MACROS) para el dimensionamiento de escaleras de peces

Abstract

The present paper has an analysis of the different types of the existent fish passes, suggesting its advantages and limitations according to research already carried out by universities. Also, a collection of the most important aquatic species found in the Ecuadorian rivers is made. For this, a recollection and analysis of public domain environmental impact about dams in Ecuador.

Following, analysis already mentioned, and abacus are used to set up swim velocity, stay time of the fishes according to its capacities to making a MACRO (computer coding) that could follow a design for two types of fish passes which can better adapt to the ichthyofauna on the Ecuadorian rivers. These fish passes being of successive ponds and each slot passes. In this way, the tool that allows the design for this passing structure has suitable conditions for the fish crossing.

The results are presented through a practical example where is detailed the calculation process that the MACRO uses to obtain the results, a tutorial video is also added that facilitates the handling of the MACRO, allowing the correct use of this tool.
