The Use of Ulva in Integrated Multi-trophic Aquaculture (IMTA), an Ecological Approach For
A Sustainable Aquaculture
The scarcity of freshwater, overfishing and declining ocean biodiversity, marine eutrophication by anthropogenic activities, and the increasing demand for seafood have all required attention from a more comprehensive, global perspective. Moving from conventional aquaculture toward an ecological approach to developing and managing a sustainable aquaculture that cares for environmental and sociological aspects can bring relief to at least some of these problematic issues. Nutrient removal using Integrated Multi-Trophic Aquaculture systems (IMTA) is a promising ecological approach for sustainable aquaculture. The rationale behind the IMTA systems is to convert the excretions of the organisms cultured upstream into valuable food for the organisms cultured downstream. In marine IMTA systems, algae and halophyte plants have a high capacity for nutrient uptake per unit of culture area and can be an essential additional valuable product. In addition to nutrient removal by the green seaweed Ulva lactuca, the IMTA system proved to be a reliable source of sustainable biomass for human consumption, animal feed and high-value by-products for the food additive industries.
IMTA systems in offshore cage cultures and land-based facilities will improve the food conversion rate (FCR) and diversify the mariculture products, ultimately increasing profit for the farmer. In addition, they will often create additional jobs and, no less importantly, will reduce environmental pollution.

Keynote speaker
Marianne Thomsen
Professor, KU Food, Copenhagen University
Seaweed-based emission capture
and utilization in regenerative
circular bioeconomies
The mission of professor Thomsen is to develop integrated sustainability assessments models delivering policy and business decision support for the design of restorative circular bioeconomies that delivers non-financial profits such as ecosystem and human health. Scientific focus areas of Thomsen are complex system analysis, process and hybrid LCA and absolute sustainability science.
Not just another conference

Delegate testimonials
Delegates tend to come back year after year – read why…
In this place here at the conference is a good space and room to meet people who are not too scientific, but very pragmatic and oriented towards products, and that is where my interest is. There are also very nice people at the conference

Christian Koch
So, thank you for inviting me to the Nordic Seaweed Conference.
It is such a pleasure to come back.
I was here six years ago, and it was a wonderful location, and it is just an exciting place to learn.

Prannie Rhatigan
Conferences are interesting places to meet both young people and people who have been in the field for a long time, from all over Scandinavia and many other places around the world. It’s a good place to get updated on what is happening in research and applications of seaweed.
