Already 30% of commercially-used fish stocks in the world's oceans are overfished. Further 50% are on the verge of overfishing.
The constantly growing demand for fish, at the same time as the fishing yield is stagnating or declining, leads to considerably increasing prices. Since 1990 the retail price index for fish and seafood in Germany has been growing on average about 2% per year. Hence, the price increase rate is twice as high as it is for meat, fruit or vegetables.
In the last few decades, over the course of the worldwide overfishing, aquaculture developed into an alternative to cover the increasing human demand for fish. Every second fish eaten in the world already originates from farmed production. Currently marine aquaculture is operated exclusively in coastal areas, which causes extensive problems, such as the discharge of waste and nutrients, the escape of farmed fish or the transmission of diseases to wild stocks. Furthermore also conflicts of interests with other users lead to a constant discussion about the sustainability of this technology.
Also the increasing worldwide water pollution of coastal areas due to urbanization leave doubts about the future of open water aquaculture.
Therefore, a paradigm shift is taking place in aquaculture. The ecological risk of open water aquaculture is leading to technological development, which will replace the simplicity of many farm types by modern aquatic biotechnology. These systems are based on sophisticated water and material cycles and reduce the impact of aquaculture on the environment.
With the oceanloop, developed by neomar, the inland production of seafish and other marine organisms becomes reality. It is an alternative to conventional fish farming in open water aquaculture. Read more about the technology.
