    • Effect of organic nitrogen and carbon mineralization on sediment organic matter accumulation in fish ponds 

      Jiménez, Ricardo; Verdegem, Marc; van Dam, Anne A.; Verreth, Johan (Aquaculture Research, 2005-07-01)
      In aquaculture, ponds with high loads of organic inputs, organic matter accumulates at the bottom over time. Uneaten feed, senescent phytoplankton and faeces are the principal sources of accumulated material, but quanti¢cations ...
    • Nitrogen budget and fluxes in Colossoma macropomum ponds 

      Jiménez, Ricardo; Avnimelech, Yoram; Verreth, Johan; Verdegem, Marc (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 

      Jiménez, Ricardo (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, ...
