Alternative wood-based ingredient for salmon feed can replace fishmeal, says US biotech firm


Arbiom, a US-based agricultural-biotechnology company which develops solutions to convert wood into food, has announced the success of a recent scientific study evaluating SylPro®, its alternative protein ingredient for juvenile Atlantic salmon feed.


The study, conducted by Matis Icelandic Food & Biotech R&D as part of the SYLFEED project, was designed to demonstrate the nutritional performance of SylPro in comparison with conventional plant and animal protein sources.


"These findings indicate that SylPro can be used to replace fish meal or plant-based proteins in feed for juvenile Atlantic salmon, a crucial developmental stage, and deliver equivalent nutritional performance as conventional protein sources up to 20% inclusion level," said Alexandra Leeper, PhD candidate from Matis.


In the study, Atlantic salmon feeds were formulated with SylPro as a complement to or replacement for fishmeal and plant-based proteins at various inclusion rates. The study was designed to evaluate the product's nutritional performance in terms of body weight gain as well as its effects on the gut microbiome, which researchers measured over the course of a five-week trial period.


"SylPro represents a scientifically-backed new protein source for aquaculture feed producers and farmers, which outperforms current commercial protein sources", said Dr. Jon Arnason, senior animal nutritionist from Matis.


The study results showed no statistical difference in body weight gain for SylPro compared to the control diet up to the 20% inclusion level. Additionally, there were no differences in fish mortality across treatments.


These results support the results from previous trials evaluating SylPro for use in hybrid striped bass.


"This represents another critical milestone in Arbiom's path to commercialising the SylPro product as we continue to validate its efficacy across multiple animal feed applications," said Marc Chevrel, CEO of Arbiom.


SylPro is produced from wood through Arbiom's process, which integrates fractionation and bioconversion technologies to efficiently convert wood residues into fermentable substrates for micro-organism production through pre-treatment and fermentation processes. The final product is a dried yeast, which is nutritional protein source for use in aquafeed, and other animal feeds.

More results from this trial and achievements made by the SYLFEED Consortium in supporting sustainable future protein production were to be presented at the Aquaculture Europe event on October 8-10 in Berlin, Germany.


Arbiom was also selected as one of three finalists in the Innovation Awards at the 2019 Global Aquaculture Alliance Leadership GOAL event and will present its innovative solution to sustainable protein for aquaculture at the event in Chennai, India on October 22-24.
