Abstract
The recirculating aquaculture system for Anguilla constructed of the breeding pool of fiber reinforced plastics and biological aerated filters .The grouper Anguilla bicolor pacifica with an initial boby weight of 19 .6 (A),8.2(B),2.99(C)g were reared in this system at stocking density of 14.92(A),11.33(B),9.25(C) kg/m3 for 113 days.The results showed that the final body weight of 74.99(A),25.95(B) and 7.74(C)g, which the stocking density of 23.68 kg/m3,35.63 kg/m3,56.89 kg/m3, which the specific growth rate(SGR) of 1.18%/d,1.02%/d,0.84%/d, and food conversion rate ( FCR) of 1.28,1.25,1.42 were reached for grouper , and the survival rates were above 98 .9%.The water recycling rate was 84.5% in re-circulating aquaculture system .The water consumption was about 0.65 m3/kg fish in this system .The power consumption and energy consumption of unit net yield was 4.69 kW· h/kg, 2.01 yuan/kg.The results showed that the system has a good property with energy-saving and emission-reductions and better effect of culture .关键词
