Propagating Seaweed for a Sustainable Future

Integrated Aquaculture Services (IAS)

 

Hortimare combines a high yield production of seaweed with a solution

for fish farmers who are dealing with quota, eutrophication and salmon lice.

 

Integrated Aquaculture Services (IAS) works by growing seaweed in

the local ecosystem of the salmon farms.

 

Seaweed uses the phosphorous and nitrogen in the water to grow,

thereby lowering the impact of eutrophication. At the same time,

it attracts small fish, all kind of filter feeders and other species,

which predate on the larvae stadium of salmon lice,

lowering the pressure of salmon lice at the fish farm

(Ecological Salmon Lice Prevention (ESP)).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ESP prevents the extensive need of chemicals and other

non-environmental friendly approaches to combat these

issues. Together with the Solund based fish farmer

Sulefisk AS (a member of Salmon Group) Hortimare has started

developing and testing the concept in 2010. This pilot project

has proven that the IAS concept works and benefits both the

fish farmer and Hortimare.

IAS is also known as Integrated Multi-Trophic Aquaculture (IMTA).

The efficiency of IMTA to mitigate the environmental issues associated

with intensive marine animal aquaculture has been demonstrated on

both experimental and pilot scales and more recently by institutions

and companies in Canada and Chile.
