项目摘要

According to the UN, the world’s population is projected to reach 9.3 billion by 2050 and the present per capita availability of protein cannot be met by livestock and dairy farming sectors alone. Conservation International states that “the low environmental impact of aquaculture should be expanded to alleviate the growing global food crisis”. Expansion in aquaculture however is prohibited due to the high cost and limited availability of live feed e.g. Artemia. Similarly, salmon production is affected due to the low volumes of wrasse cleaner fish available to delouse salmon from parasitic sea lice - this is a major problem in the sector and is affecting Scotland, Norway, Ireland and Chile. WFL wish to develop new aqua-feed formulations as well as a new high-throughput processes capable of manufacturing high quality micro-aquafeed pellets. The proposed aqua-feed will allow for sustainable and cost effective rearing of fish species at substantially reduced cost compared to using live feed. WFL estimate savings could be as high as 55-60% since the proposed nutritionally rich aqua-feed will necessitate the need for reduced quantities to be utilised as feed. Nutritionalists have evaluated cheaper feeds based on vegetable proteins but are associated with decreased growth rates and therefore yields [FAO].

根据联合国的数据，到2050年，世界人口预计将达到93亿，目前的人均蛋白质供应量无法仅靠畜牧业和奶牛业来满足。国际养护组织指出，“水产养殖对环境的影响较小，应加以扩大，以缓解日益严重的全球粮食危机”。然而，由于成本高和卤虫等活饲料供应有限，水产养殖的扩张受到禁止。同样，鲑鱼生产也受到影响，因为可用于消除鲑鱼寄生海虱的濑鱼清洁鱼数量少-这是该部门的一个主要问题，正在影响苏格兰、挪威、爱尔兰和智利。WFL希望开发新的水产饲料配方以及能够生产高质量微水产饲料颗粒的新的高通量工艺。拟议的水产饲料将允许可持续和具有成本效益的鱼类养殖，与使用活饲料相比，成本大幅降低。WFL估计节省可能高达55-60%，因为拟议的营养丰富的水产饲料将需要减少用作饲料的数量。营养学家已经评估了基于植物蛋白质的更便宜的饲料，但与生长速度下降有关，因此产量下降[粮农组织]。
