Conceptualization and validation of a dynamic model for the simulation of nitrogen transformations and fluxes in fish ponds
(Elsevier, 2002-11-01)Nitrogen is a key element in aquatic environments and an important pond management variable. In aquaculture systems, nitrogen accumulation eventually leads to a deterioration of the system. The interactions between various ... -
Nitrogen budget and fluxes in Colossoma macropomum ponds
(Blackwell Publishing Ltd., 2005-07-01)This study quanti¢ed the accumulation of nitrogen (N) in the water column, sediments, ¢sh and seepage water during a production cycle of Colossoma macropomum. By combining estimates of the deposition rates of uneaten feed, ... -
Nitrogen transformations and fluxes in fish ponds: a modelling approach
(Wageningen University, 2001-04-18)Nitrogen is a key element in aquatic environments, and in Aquaculture it is an important pond management variable. In current aquaculture research two important goals are to maintain the water quality within the system, ... -
Organic matter sedimentation and resuspension in tilapia (Oreochromis niloticus) ponds during a production cycle
(2002-07-01)The rates of sedimentation and resuspension of organic carbon and total nitrogen were measured in earthen fishponds, based on nutrient input, water quality parameters and fish size and biomass. Material collected in ...
