英文摘要This study used 4 commercial value species, distributing in the coastal area of the Yellow Sea, to form an artificial food chain: Isochrysis gatoana--Anemia salina--Ammedytes resonatus -- Sebastodes fuscescens. Aquarium experiments were respectively carried out for certain periods. Analysis of the data obtained during the run of the three conversion artificial food chain show that consumption of 235. 2 kg fresh (148. 3 kg dry weight) Isochrysis gathana produced 1 kg fresh weight (1 kg dry weight) Sebastodes fuscescens. Concentration of 1 J energy by Sebastodes fuscescens requires Isochrysis galbana containing 11 0. 7 J energy. Since the alimentary canal of Actemia salina was not totally evacuated of food residues at the end of experiment, their measured body weight increment would be slightly higher than the actual value.
