해수활어수조에서 붕장어 (Astroconger myriaster)와 넙치 (Paralichyhus olivaceus)에 의한 오염물 발생량 산정 = Measurement of Waste Generation in Seawater Aquaria by Common Conger (Astroconger myriaster) and Olive Flounder (Paralichyhus olivaceus)

다국어 초록 (Multilingual Abstract)

Waste concentration and waste generation rate in seawater aquaria by common conger (Astroconger myriaster) and olive flounder (Paralichyhus olivaceus) were investigated. The initial fish density of common conger and olive flounder were 3% and 2.8% of total weight of aquarium water, respectively. Wastes in the seawater aquaria, such as protein, total suspended solid (TSS), ammonia, turbidity and chemical oxygen demand (COD) increased with days after stocking. Protein generation rate of common conger increased until 1day after stocking while that of olive flounder increased until 3days. The average protein generation rates of common conger and olive flounder were 0.28g/kg･day and 0.21g/kg･day, respectively. The trends of other waste generation rate were similar to protein generation rate.
