NUTRIENTS DYNIMIC IN AN AQUAPONIC RECIRCULATING SYSTEM FOR STURGEON AND LETTUCE (LACTUCA SATIVA) PRODUCTION

Abstract

Aquaponics are modern production systems, which integrate the aquaculture technology with hydroponic systems (vegetable production without soil) with a goal of fructification of residual nutrients resulted from metabolic activity of fish biomass as high quality vegetable biomass sealable as ecological products. In the present study, as a first step in aquaponic recirculating systems evaluation, the authors aim to compare two types of recirculating systems: classical (hereby noted with RAS) and integrated/aquaponic (RAS_A) regarding water quality parameters generally, and TAN (total ammonia nitrogen) production and transformation, particularly.
