Salmonide Growth - A Sustainable and Viable Alternative for the Valorization of Unproductive Agricultural Land

Abstract Salmon farming includes concerns about artificially growing and improving the populations of Salmonidae species on specialized trout farms. Due to the improvement of salmonid species, today productions are obtained throughout the year, in a relatively short time and at increasing densities. Thus, in order to obtain high and quality yields, the crop areas are incomparably smaller than those intended for other crop species, being used impracticable lands for agriculture or low yield lands. The study brings to the fore the parameters that must be taken into account, in the project phase, before setting up a farm specialized in trout farming: geotechnical study, water source, physics-chemical parameters and growth basins. The growth of trout is related to the agricultural sector and the technique of the agricultural production process, because knowing the soil and its properties, we can improve the action of bacteria and benthic flora and fauna, important links of the food chain in the ecosystem. The trout farm is a profitable alternative to the traditional farm, because the area needed to set up the fish farm is much smaller.
