Importance of nickel as a nutrient in aquaponic systems - some theoretical considerations
Journal Title: Ecocycles - Year 2018, Vol 4, Issue 2
Abstract
This paper calls the attention to the important role the microelement nickel plays is the decomposition of urea (produced by the fish as waste), and thus to its potential role in aquaponic systems. Since nickel is not included in the list of micronutrients essential to fish growth and development, fish feeds probably do not contain sufficient amounts of it. Therefore, trace amounts of soluble salts or complexes of nickel probably need to be added to aquaponic systems in order to achieve the systems' stable operation.
