Aquaculture
IRIS Biomiljø offers research and consultancy within aquaculture fields such as assessment of high-technology systems and monitoring of environmental consequences of aquaculture.IRIS has been involved in numerous aquaculture related projects over the last 20 years, involving a whole range of fish and crustacean species as well as culture techniques. The main activity takes place in Norway and in shrimp producing Asian countries.

Need for oxygen injection in fish cage farms ( 2001-2005)
The project started by monitoring environmental conditions at the EWOS Innovation cage farms. At these and other farms, both in Norway and Canada, dissolved oxygen concentrations inside and outside salmon cages were the focus of attention. Studies showed that fluctuating oxygen concentrations, especially at high temperature, affect the appetite and growth of the fish stock. Further studies confirmed the need of adding oxygen in the salmon cages, in order to optimise environmental conditions.
Intensive shrimp culture systems in Thailand (2006-2008)
The aim of the project is to study the effects of adding liquid oxygen in order to optimise environmental conditions in shrimp ponds. Collaboration with Asian Institute of Technology, University of Bangkok.
Recirculation technology in aquaculture (Asian Sea Bass) in Sri Lanka (2008 - 2011)
The objective of this project is to study and to test the efficiency of the systems.
Development and testing of systems for production of salmon and tilapia in Eastern Europe and China ( 2010 - )
Environmental and socio-economic impacts of shrimp farming in Bangladesh (1997-2002)
A 6-year project involving Bangladesh Agricultural University, Norwegian Institute for Water Research, and IRIS.
Online monitoring in Aquaculture ( 2007 - Ongoing)
Joint project between IRIS and Orbit Aquacam using submerged camera connected to environmental sensors for surveillance of fish stock and environmental conditions in cages.
