水产饲料配方中使用的一个关键成分是鱼油，它是从小型海洋中上层鱼类中生产的，代表着有限的渔业资源。目前，全球鱼油产量已经达到平台期，预计不会超过目前的水平。最近的估计表明，鱼油可能最早在2005年就无法满足快速增长的水产养殖业的需求。因此，目前水产饲料行业对评估鱼油的替代品非常感兴趣。马来西亚和其他热带国家不断扩大的油棕榈树种植为水产饲料配方提供了不断增加的棕榈油产品供应的可能性。关于在水产饲料中使用棕榈油的研究始于20世纪90年代中期，这篇综述检验了这些研究的一些发现。在鱼类饲料中使用棕榈油总体上显示出令人鼓舞的结果。据报道，鱼片的生长、饲料效率、蛋白质利用率、繁殖性能和更高浓度的α-生育酚都得到了改善。综述了棕榈油能够在叉尾鱼饲料中替代鱼油的最近证据。展望了棕榈油在水产饲料中的应用潜力和未来的实验方向。水产养殖饲料行业为增加和多样化棕榈油产品的使用提供了一个很好的途径。
One key ingredient used in the formulation of aquafeed is fish oil, which is produced from small marine pelagic fish and represents a finite fishery resource. At the present time, global fish oil production has reached a plateau and is not expected to increase beyond current levels. Recent estimates suggest that fish oils may be unable to meet demands from the rapidly growing aquaculture industry by as early as 2005. Therefore, there is currently great interest within the aquafeed industry in evaluating alternatives to fish oils. The ever-expanding oil palm cultivation in Malaysia and other tropical countries offers the possibility of an increased and constant availability of palm oil products for aquafeed formulation. Research into the use of palm oil in aquafeed begun around the mid-1990s and this review examines some of the findings from these studies. The use of palm oil in fish diets has generally shown encouraging results. Improved growth, feed efficiency, protein utilisation, reproductive performance and higher concentrations of alpha-tocopherol in fish fillets have been reported. Recent evidence for the ability of palm oil to substitute for fish oil in catfish diets is reviewed. The potential of palm oil use in aquafeed and future experimental directions are suggested. The aquaculture feed industry offers a great avenue to increase and diversify the use of palm oil-based products.
