Sugar kelp is a brown algae of the family Laminariaceae.
It is widespread in all Danish waters and usually lives at a depth of 10 - 30 meters where there is a rocky bottom. Sukkertang trives bedst i vandtemperaturer under 15 grader og hvis temperaturen kommer over 20 grader vil den hurtigt begynde at dø_cc781905- 5cde-3194-bb3b-136bad5cf58d_from top to root. The root usually survives as the algae is perennial and will start to grow again in the autumn. However, a very hot summer like 2018 caused large populations to completely disappear from certain areas in Danish waters.

Another factor for algae growth rates and well-being is the salinity or salinity of the water, which is measured in parts per thousand. Research shows that sugar seaweed thrives best at min. 17 per mille measured as an average of the year.

The salinity around Kerteminde fluctuates between 15-20 per thousand and therefore there have been trials with the production of sugar seaweed which has proven to be possible with a good yield and good quality.

Efterspørgslen på tangprodukter er stigende og derfor er planen at der i 2021 startes en produktion til efteråret som vil være klar for harvest in April 2022.
