Abstract

Background and objectives: This study evaluated the effects of an aquamimicry system on growth performance, water quality, and economic efficiency of dense Litopenaeus vannamei culture in Gomishan (Golestan Province).

Materials and methods: Shrimp post-larvae (PL12) were stocked at 20 per m² for 120 days. Two treatments were compared: control (TC: traditional method with commercial feed and water exchange) and aquamimicry (TA: 16 kg fermented rice bran + 14 L probiotics, with 20% water exchange). Water physicochemical parameters, growth performance, plankton abundance, and economic indices were analyzed using t-test (p < 0.05).

Results: Dissolved oxygen was more stable in TA (6.5 vs. 6.2 mg/L). pH was stable in TA (7.6-8.1) but increased in TC (7.2-8.5). TSS increased in TC but decreased in TA. Growth performance was significantly higher in TA (p < 0.05). Feed conversion ratio improved in TA (1.26 vs. 1.51) and total biomass increased by 44.4%. Production cost per kg of shrimp was 25.4% lower in TA.

Conclusion: The aquamimicry system improves production efficiency, reduces environmental impacts, and increases economic returns, offering a sustainable alternative for L. vannamei farming in Gomishan.
