ABSTRACT
The study “Application of IoT Technology combined with cold plasma techniques in larvae production and commercial farming of swamp Eel in Soc Trang” was conducted from 2023 to 2025, aiming to stabilize water quality and improve the survival and growth rates of swamp eel in Soc Trang. The results showed that although water quality parameters in the nursing and grow-out systems fluctuated from the larvae stage to commercial size, these variations did not adversely affect the growth and development of the swamp eel.
Analysis of Coliform levels (CFU/mL) in the nursing system indicated values ranging from 2.2 × 10² to 3.3 × 10³, and notably, E. coli was not detected (CFU/mL). In the nursing experiment from Larvae eel to 30-day-fingerlings, body weight and survival rates in Treatment 1 (NT1) (brood stock fed trash fish) were higher than those in Treatment 2 (NT2) (brood stock fed a 42% protein commercial feed). After 90 days of nursing, the survival rate in NT1 reached 92.6% with a yield of 3.586 kg/m², higher than NT2 (81.2% and 2.699 kg/m², respectively) (p < 0.05). In the grow-out phase, the stocking density of 800 fish/m² (NT2) resulted in higher total yield and production than NT1. However, the stocking density of 600 fish/m² (NT1) produced better results in terms of body weight, survival rate, and profit margin (%). The feed conversion ratio (FCR) in both commercial farming treatments was low (1.13–1.16), indicating high feed utilization efficiency.
Application of IoT technology, combined with sensor networks and plasma techniques, provided an effective solution for stabilizing and managing water quality in swamp eel nursing and grow-out systems. This approach offers significant scientific and practical value by improving survival rates, growth performance, and the overall efficiency of larvae production and commercial farming systems for swamp eel.
