Propagating Seaweed for a Sustainable Future

Seaweed for a sustainable future


At Hortimare we believe that sustainable and circular approaches are the only possible future

for our planet.


The global demand for food in general and for high quality proteins specific is growing.

Subsequently the pressure on land by extensive agriculture rises, causing ecological disasters.


In answer Hortimare developed efficient, circular and sustainable concepts of aquaculture where

seaweeds are the renewable and eco-neutral sources of marine proteins and the floating seaweed production field developes into a biodiverse, stabilising ecosystem supporting sustainable salmon farming.


By producing seaweeds (macro algae) next to salmon farms in the Norwegian fjords the high levels of

phosphorous and nitrogen can be reduced while providing a habitat for predators of salmon lice.

This is a perfect circular system: we grow seaweed using the by-products of salmon farming and

produce seaweeds rich in marine proteins, to be used in salmon-feed, whilst reducing the

salmon lice pressure, reducing the use of pesticides. Thus we provide a service to salmon farmers while

ensuring a constant flow of sustainably produced high value algae derived marine proteins.

In October and November of 2015 Hortimare successfully seeded and planted 2 hectare of seaweed plantlets at their own site off the coast of the island Solund. The seeding and planting activities took place in a little over a week with an enthusiastic team of employees.


Divided over Norway from just a little stretch down from Bergen up till the far North of Norway lots of clients were provided with juvenile seaweed plantlets or suspension of sporophytes for direct seeding. Also clients in The Netherlands and Denmark were served in time with materials as well as support from Hortimare to boost the seaweed farming production chain.


During the month of May this year Hortimare could start harvesting the seeded plantlets of last autumn. Huge quantities of beautiful seaweed of species Saccharina latissima (sugar weed) and Alaria esculenta (winged kelp) were brought in and processed by the harvesting machine built by IHC Merwede. Again thanks to our team and supported by suppliers, visited by clients, press and consortium partners from various projects, Hortimare looks back upon a great harvest.


As nature keeps her pace up, Hortimare is already preparing for the next seeding season and looks forward of receiving orders from clients for this coming autumn. The team of Hortimare is at your service. Our contact details can be found on the contact page of this website. Norwegian Clients can contact our local staff via the Norwegian website www.hortimare.no.


We wish our clients and stakeholders an innovative and sustainable 2016 and a great seaweed season!
