บทคัดย่อ

The Experimental Fishery Station of the Royal Project Foundation established at a Karenvillage, Mae Klang Luang, on Inthanon Mountain has been cultivating rainbow trout with theobjective of providing alternative employment and for providing an additional protein foodsource for the Karen people. The trout farm generates wastewater containing nutrients, suchas ammonia-nitrogen and phosphorus. Currently, wastewater is released from the farm tothree different sinks, i.e., upland rice field, experimental rice field with crayfish farm andnatural stream nearby the village. The objective of this research is to determine quality andquantity of wastewater from the rainbow trout farm as a nutrient source for the upland ricecultivation and to offer an appropriate wastewater management option for the farm. Further,an additional advantage of wastewater use for upland rice (i.e., Med-Luang variety)cultivation is the reduction of nutrients in wastewater before discharging to natural streams.The information was collected as both primary and secondary data. Total nitrogen (ammonianitrogenand nitrite) and ortho-phosphate were analyzed. The wastewater contained totalnitrogen of 0.21ฑ 0.08 mg
