Ten-year simulations of organic matter concentrations in tropical aquaculture ponds using the multiple pool modeling approach

Autor: Raul H. Piedrahita, Daniel M. Jamu

Publikováno v: Aquacultural Engineering. 25:187-201

The accumulation rate of organic matter has been used to develop guidelines on sediment management in tropical aquaculture ponds. However, there is conflicting evidence as to the rate of sediment organic matter accumulation and whether steady state c
