EV-85-1  aA dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of  Engineering, School of Environment, Resources and Developement  aThesis (Ph.D.) - Asian Institute of Technology, 1985  aThe research programme on aquacultural treatment of nightsoil  has been conducted at the Asian Institute of Technology (AIT) for  about 10 years. This dissertation emphasizes only on the research  in which nightsoil and biogas slurry are fed directly into  single-stage, non-flow-through ponds for the production of algae  and fish Tilapia (Oreochromis niloticus). The culture of  herbivorous fish such as Tilapia in the same pond to graze on the  algae is practical, in order to produce the fish protein biomass  which is easily harvestable for animal (or human) food.  Empirical and dynamic models describing the performance of  septage and biogas slurry fed fish ponds were developed to  simulate the temporal changes of various physico-chemical and  biological parameters including dissolved oxygen, carbon dioxide,  bacteria, algae, and fish growth. These models were based on the  basic mechanisms and phenomena occurring in the ponds, and  the simulated resul ts calculated from the Continuous System  Modelling Programme (CSMP) computer package available at the AIT  Regional Computer Center.  0aSewage lagoons0 aChongrak Polprasert,eChairperson1 aLohani, B.
