Abstract
The paper reported incomings and outgoings budget of dissolved oxygen (DO) in the giant tiger prawn (Penaeus monodon) desalting culture ecosystem in estuarine area in 1997 and 1998. The gross oxygen production (GOP) of water column in the surface layer was more (even significantly) than the oxygen consumption of aquatic respiration (AR),but the GOP in the bottom was less evidently than the corresponding AR,which was the common "oxygen debt" phenomenon. Among the oxygen consuming factors, AR was the largest oxygen consumer, which made up more than 70% of the total oxygen consumption of water column; benthic respiration (BR) was the second and accounted for about 20% of the total oxygen consumption; the proportion of prawn respiration (PR) was lower and increased remarkably with culture period. The ratio (B/P) of mean compensation depth (B) to mean transparency (P) in Giant tiger prawn pond, 1.42±0.53, was lower than that in fishpond (1.5~2.5). Therefore, the oxygen production in the depths of pond was reduced. DO in the Giant tiger prawn desalting culture pond was in disequilibrium, the outgoings outweighed the incomings.关键词
