ALLER FLOW - CREATING VALUE FOR ATLANTIC

SALMON FARMING IN RAS

Aller Flow is a news feed for Atlantic
Salmon in Recirculating Aquaculture
Systems (RAS). The feed is optimized
for performance in terms of excellent
water quality and healthy fast-growing
fish.
Production of Atlantic salmon in RAS
is gaining popularity across the globe
with steadily rising production volumes
each year. While technically advanced
and requiring large investments, RAS
also calls for highly sophisticated and
advanced fish feeds.
Following the increasing trend of
large-scale production of Atlantic
salmon in RAS across the world, Aller
Aqua introduces Aller Flow as the best Faeces structure of Aller Flow (left) compared to a competing RAS feed (right)
choice for farming Atlantic salmon in
this sophisticated environment. Thor-
oughly tested and developed at the
trial station at Aller Aqua Research in
Buesum, Germany, Aller Flow is creat-
ed considering the impact of the feed
on the entire production system whilst
maintaining focus on fish health and
growth.
“Aller Flow has been developed to
enable the highest feed efficiency, not
only in terms of growth but also feed
conversion. Every digit in improved
feed conversion means fewer nutrients
to be handled by energy-consuming
filtration units in RAS. Keeping this in Faeces particles dispersion after a stirring test with faeces from fish fed Aller
mind, we were able to improve the FCR Flow (left) compared to faeces from fish fed a competing RAS feed (right) as an
by no less than 4% in Atlantic salmon indicator for water turbidity
fed Aller Flow compared to a compet-
ing RAS feed. That is a huge difference
when producing several thousand tons
of salmon! We have also significantly
improved the feces structure from fish
fed Aller Flow compared to a compet-
ing RAS feed, meaning that the more
compact and stable feces are efficient-
ly transported through and removed
from the system by filtration units. This
will make a big difference for the ef-
ficiency of the RAS as well as the eco-
nomic result”, explains Dr. Robert Till-
ner, Product Manager at Aller Aqua.

Aller Flow contains no animal
by-products and is available in sizes 3
& 4.5mm for Atlantic salmon farmers in
RAS.
