Abstract: The energy saving water recycling system for Epinephelus fuscoguttatus culture consisted of fish pond, protein separator, purifying trough and water recycling pump. The water recycling and purifying facility was built above one side of the fish pond, and each pond had one water recycling and purifying facility correspondingly. During the experiment in eight months, by the comprehensive eco-purification of bio-film degradation and plant absorption, water recycling rate was 88%, the fish yield density was 19.74 kg/m3. The daily weight gain of the fish was 1.14 g/(ind•d), and the fish weight gained 11.55 fold. The cost of the purifying facility for per unit water volume and the per unit yield were 507.3 yuan/m3 and 27.92 yuan/kg respectively. The electric energy consumption of per unit production was 3.813 kW•h/kg, 6.05 yuan/kg. The results showed that the system has a good production property with low cost and energy saving.
