Background

Aquaculture represents a solution to the future world demand for healthy protein while challenges that require urgent solutions are emerging in feed production, such as the rising costs of feed protein and massive imports. From a European perspective, a large proportion of the protein demand is met with imported protein. This article will focus on the development of protein-rich microorganisms (i.e. Single cell protein) as a novel raw material in fish feed which can be produced as an important co-product in wood-based biorefineries, increasing sustainability and the utilization of organic waste material.

Scope and Approach

Developing a safe and sustainable protein resource from local organic waste-material represents an opportunity for Europe to decrease its reliance on nutritional imports, and address mounting food sector sustainability concerns and a growing protein deficit. At the same time, the nutrient recycling industry represents a growing industry, addressing waste valorization and protein feed production concerns at once.

Key Findings and Conclusion

An industry and research collaboration has focused on selecting which microorganisms and residual streams from a wood-biorefinery site that would be best suited for production of SCP. The study showed that 38–68% of the fishmeal in a Nile tilapia (Oreochromis niloticus) feed could be replaced with SCP while maintaining a similar or slightly improved fish growth. As reported by FAO, aquaculture production of Nile tilapia in 2014 was 3.7 million tonnes, making it one of the most produced fish species in the world.

来自林业的安全和可持续蛋白质来源–以鱼饲料为例

背景

水产养殖是未来世界对健康蛋白质需求的一种解决方案,而饲料生产中正在出现需要紧迫解决方案的挑战,例如饲料蛋白质成本的上涨和大量进口。从欧洲的角度来看,进口蛋白质可以满足很大一部分蛋白质需求。本文将重点研究富含蛋白质的微生物(即单细胞蛋白质)作为鱼饲料中的一种新型原料的发展,该产品可以作为木质生物精炼厂的重要副产品生产,从而提高可持续性和对有机废物的利用材料。

范围和方法

利用当地有机废物开发一种安全,可持续的蛋白质资源,对于欧洲来说,是一个减少对营养进口的依赖,解决日益严重的食品部门对可持续性的关注和日益严重的蛋白质短缺问题的机会。同时,营养物回收行业代表着一个不断发展的行业,它可以立即解决废物增值和蛋白质饲料生产方面的问题。

主要发现和结论

一项行业和研究合作专注于从木材生物精炼厂中选择最适合SCP生产的微生物和残留流。研究表明,尼罗罗非鱼(Oreochromis niloticus)饲料中38%至68%的鱼粉可被SCP替代,同时保持鱼的生长相似或略有改善。根据粮农组织的报告,2014年尼罗罗非鱼的水产养殖产量为370万吨,使其成为世界上产量最高的鱼类之一。
