台灣觀賞魚的出口產值，自民國87 起至97 年間，每年以14% 穩定成長 (行政院財政關稅總局)，為台灣精緻農業之重要產業。但孔雀魚 (Poecilia reticulate, Guppy) 及彩色血鸚鵡魚 (Cichlosoma citrinellum Х C. synsilum, Candy blood parrot)，於物流中容易引起魚隻病毒或細菌性感染，損害動物健康，死亡率高於20%，造成業者虧損，故提升此二魚種之存活率為本研究主要解決之問題。過去本研究室發現高粱酒糟，為金酒公司每日產出250 噸之廢棄物，提升血漿抗氧化力、延緩LDL 氧化、降低血液黏度、攝食後冬季之成長率提升，可回收利用為低成本之抗緊迫添加劑，其功效成分已初步鑑定；一條根 (Glycine tomentella Hayata) 萃取物具抗發炎之功效，其有效成分亦已鑑定；二種萃取物對吳郭魚 (Oreochromis mossambicus) 及烏魚 (Mugil cephalus) 均有抗低溫及抗運輸緊迫之功效，推測亦可能增加觀賞魚於物流中抗緊迫之能力，而提升存活率。故本研究擬探討孔雀魚及彩色血鸚鵡對此等植物之耐受性，可應用之配方、及浸泡或注射之劑量與使用方法。若死亡率可降至 ≦4% ，可確保觀賞魚物流業者之競爭力及商譽，未來可供國內其他觀賞魚物流之用，因而增加國內觀賞魚業者外銷之競爭力。 The ornamental fish export has increased steadily by 14% annually between 1998 and 2008. It has become an important elite agro industry. During the course of logistics, the stress causes Poecilia reticulate (Guppy) and Cichlosoma citrinellum Х C. synsilum (Candy blood parrot) susceptible to bacterial and viral infections. The mortality rate can be up to 20% resulted in serious business loss. The objectives of this project are to improve the survival of these 2 fishes. Our previous study formed sorghum distillery residue (SDR) a by-product form sorghum distiller at 250T/day. The SDR extract is able to increase the plasma total antioxidant capacity, retard the LDL oxidation, lower blood viscosity and improve growth in winter, in addition, reduce mortality in tilapia (Oreochromis mossambicas) and grey mullet (Mugil cephalus). Therefore, the bioactive compounds have been identified. The SDR is possible for reutilization to be a low-production-cost, anti-stress agent. I-Tiao-Gung (Glycine tomentella Hayata) has also been previously extracted and demonstrated its anti-inflmammatory activity. The active compounds have been identified. Fish fed either of the 2 extracts showed improving cold acclimation and stress tolerance during transportation. It is our hypothesis that these bioactive extracts may be applicable to the ornamented fishes to produce the same efficiency as shown in tilapia and grey mullet. In this study, we will try to determine the dosage, and the method to apply these agents by feeding, injection, dipping or immersion prior to or during shipping. The methodology established in this study may be applied to other ornamental fished logistics. If the mortality rate can be reduced to ≦4%, the compatibility and business image of our domestic ornamental fish industry will be greatly enhanced in the global market.
