The Challenges

One of the major issues in the fish farming industry is the impact it has on the environment. The use of medicine and chemicals to handle sickness and lice in addition to the waste from the farm are issues that are discussed in may forums.

Fish escaping may possibly endanger the gene pool of the wild salmon population. It is also assumed that the resurgence of lice will increase the spread of disease.

The waste from the fish and other substances used to run a fish farm often ends up in the sea or on the seabed. Several tons of waste will accumulate. There are different views on what the impact on the local environment is.

The Solution

To help solve these challenges was our main impetus for the development of the Neptun Closed Cage. Trough full scale testing we have proven to meet many of these challenges.

As the Neptun Cage is made from solid components, escapes are no issue.

In the closed cage, the water is pumped up from a depth not normally inhabited by lice and other organisms.

As a result of this the use of chemicals and/or medicine may be drastically reduced in the Neptun Cage.

Our Cage includes a system for separating and extracting waste from the fish. Full scale testing has proven to collect as much as 60-80%. A second generation separator is currently being developed.

Moving the cage due to local environmental overload might no longer be an issue.
