Zeolites in Aquacultural Primary Production

Our studies in aquacultural systems began with the ammonium-ion elimination. They were continued with the investigation of the influence of zeolites in other marine biological processes such as the culture of marine micro-algae, this is, the primary production of marine phytoplancton by products of zeolitic nature (PZNs).The PZNs were prepared in our laboratory in various ways depending on the type of base material used for their synthesis. Especially significant was the positive influence they exerted over the growth of marine micro-algae. The presence of PZNs, which increased the cellular yields in the primary production of phytoplancton, showed a dependence on the dose and on the product used.
