Preview Aquafeed Horizons (during Victam)
New research presented at Aquafeed Horizons Conference can help control
extruded aquafeed quality and to improve the product specifications used by fish
meal producers and purchasers.
The extrusion properties of fish meals produced with different industrial raw
materials and drying technologies were investigated and both the water soluble
protein level and the physical shape (fibrous vs. granular) of the fishmeal
particles found to have a significant effect on the melt viscosity and thereby
dissipation of mechanical energy in the extruder
From this, empirical models
for prediction of feed pellet quality were established. The study was based on
standardized extrusion conditions and documented the possibility to develop a
model explaining pellet hardness and durability based on fishmeal chemical
composition and physical properties.
The strengths and weaknesses of the empirical model will be
discussed by Tor Andreas Samuelsen, Senior Scientist, Fiskeriforskning, Bergen. The effect of fish meal
quality on extruded pellet density and fat absorption will also be
When and where?
Aquafeed Horizons will take place May 9-10, 2007
at the Jaarbeurs, Utrecht, the Netherlands during Victam 2007. It is organized and
presented by Aquafeed.com,
and Fiskeriforskning, the Norwegian Institute of
Fisheries and Aquaculture Research.
