AE-87-45  aA thesis submitted in partial fulfillment of the requirements for the degree of Master of Science, School of Environment, Resources and Development  aThesis (M.Sc.) - Asian Institute of Technology, 1987  aInformation from Ban Hin Lad, Northeast Thailand was used in  planning a study of bovine manure as a main input in fish raising  for small-scale farmers in rainfed areas in AIT campus as  adaptive field trial. Nile tilapia (Oreochromis niloticus), Tawes  (Puntius gonionotus) and Common carp (Cyprinus carpio) were  raised in two 200 m2 ponds by using bovine manure, the main  input. Para grass CBrachiaria mutica> was placed in a bamboo  frame for decomposition. Leucaena CLeucaena leucocephala) and  water spinach Cipomoea aguatica) were used as supplementary  feeds. The trial was conducted over a period of 7 months. Fish  production and growth, nutritive value of pond input s , water  quality and economic assessment of the production of the system  were determined. A study of the effects on the existing farming  system if using all bovine manure for fish raising was conducted  in the village by using Topical Rapid Rural Appraisal <Topical  RRA>. Tilapia performed better than the other two species in  terms of production and growth. The combination of these pond  inputs provided certain amount of nutrient to the ponds but water  fertility was still low and needed to be improved. The economic  assessment showed that return over cash cost under village  conditions was higher than that obtained under AIT campus  conditions. The mean extrapolated yield of 56. 90 kg/200 m2 /year  could supply 26. 17 percent of the animal protein needs of a  typical family in the project village. Conflicts of using bovine  manure between existing major crop enterprises and fish ponds  were controversially stated by the interviewed farmers.  0aFisheszThailand, NortheasternxFeeding and feeds1 aGartner, Joseph A., eChairperson1 aEdwards, Peter,eExamination Committee1 aWee, Kok Leong,eExamination Committee2 aFAO - UNDP, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
