Environmentally friendly fish farm for the future

Mood Harvest AS is focusing on creating a environmentally friendly fish farms for the future. We can not go into detail on the technical solutions behind the concept, but what we can tell is that we seek to convert old vessels that for other reasons are inoperative into closed fish farm installations. We believe that by reusing these types of floating structures we can achieve a well-controlled fish farming environment that is physically separated from the open sea.

The water going in and out of the tanks are to be treated, and all waste to be taken care of, either as biofuel or/and as fertilizers.


1. Better control of the feeding process means more efficient use of the fish meal and thereby less waste. This is important since farmed species rely partly to be fed with other wild fish, and we don’t want to leaves the ocean at a net loss. With global seafood consumption increases as a consequence of the increasing population we believe this is a key issue for the future of fish harvesting.

2. We do not occupy land, land that can be used for farming and housing instead. Less energy used to pump water etc.

3. Less use of medication, as a result of better diseases control. We can detect and treat diseases at an early stage reducing risk of harmful consequences. With barriers to the sea we do not introduce diseases and medicine to wild fish.

4. Climate changes caused by global warming, may/will/can cause the sea temperature to raise, as a consequence outbreak of diseases and growth of harmful algae’s can threaten the fishes in the sea and be a threaten to our food chain. With our system we will monitor the water quality and make sure that we maintain fish welfare and fish quality. By steady temperatures we can also increase fish growth. More harsh weathers will also require more robust fish farms in the future to prevent fish escape.

5. With a closed system we prevent lice that live naturally in the ocean to reproduce out of control as is in open farms. By preventing lice to reproduce we don’t need to introduce harmful insecticides to the nature.

6. Life extensions of vessels are also positive environmental measure. Better use of natural resources. Harmful wastes from previous use are taken care of and treated in an environmental friendly way. Environmental friendly non toxic coating against corrosion is to be used.

This is a few of the benefits our system has.

Why do we need closed fish farms?


  • Resistant lice are one of the biggest challenges for the industry.
  • Globally sea lice cost each year 300 million euro.
  •  Norwegian aquaculture exports for 30 billion a year, and lose up to 10 percent as a result of the parasite.


  • In 2011, 370,000 salmon escaped from Norwegian fish farms. This gives the industry a net los of 80-100 million. In addition, increased operating costs and possible claims.


  • PD costs salmon industry around 1 billion a year (2010).
  •  ILA vaccine costs (0.5kr per dose = 150 million NOK).

       What about new viruses and diseases in the future?

Just as a reminder: Chile lost 160 million dollars as a result of the ILA outbreak in 2007 – 2010.


  • Discharge of nutrients and organic material => eutrophication and algal blooms.
  • Escape => Disease, genetic diversity, productivity.
  • Chemicals for the control of lice.
  • Antibiotics and other medicines.

        Cost impact? impossible to quantify, but the numbers are high. 

On a national basis salmon fishing and aquaculture gives a turnover in the order of respectively 1.2 and 30 billion annually.
