Aquaculture Research, Volume 2025, Issue 1, 2025.This study compared the impacts of three aquaculture systems, a biofloc tank system (BTS) without sludge removal, a clear water (non‐biofloc) tank system (CTS), and an earthen pond system (EPS), on the zootechnical, biochemical, haematological, and enzymatic activities of Nile tilapia (Oreochromis niloticus). Monosex (male) fish (initial weight: 22.01 ±

Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.Recirculating aquaculture systems (RASs) represent a sustainable solution for intensive fish production, offering 90%–99% water savings compared to conventional systems while preventing nutrient contamination of natural waterways. The accumulation of nitrogenous compounds, driven by factors, like overfeeding, fish waste, and insufficient water exchange,
