BlueSea Technology AS, Norway

The Wieland Group establishes a JV for the marketing of brass nets and more for aquaculture

For the development and marketing of brass nets and cages, Wieland-Werke AG has formed the “BlueSea Technology AS” joint venture with Lerow AS in Norway. The partner has the respective know-how as well as longstanding experience in the field of aquaculture. Daniel Steitz, Wieland-Werke AG (60% JV), is the CEO, and Svein Jarle Midtøy, Lerow AS (40% JV), the COO of BlueSea Technology AS.

The world’s rising population has created an increase in demand for food. Fish is an important and healthy food source. The increasing demand leads to overfishing of the world’s oceans. Aquaculture enables the controlled farming of fish. The growth rates of this market are approx. 7% per year. Today, the largest markets for maritime aquaculture are Norway and China.

For aquaculture, specifically for the fish cages used, Wieland has developed a wire and subsequently a brass net made of the alloy Wieland BlueSea® SE1 which offers many advantages over conventional nylon nets. Wieland has thereby extended its value chain to include the weaving of nets which enables the company to manufacture and market complete aquaculture cages. To this end, Wieland has invested in a new weaving line with a weaving width of up to 12 meters at its location in Vöhringen.

The products for aquaculture are brought together under the BlueSea® brand. Aquaculture cages made of BlueSea® Mesh have a significantly longer service life than conventional nets. High mechanical strength offers very good protection of fish against predators and the net retains its form even in stronger currents and stormy weather. Brass stays naturally clean in sea water what considerably reduces cleaning effort. This in turn leads to a significant reduction of stress in fish, as interference with their habitat becomes less necessary. At the end of the net’s service life, the material is 100% recyclable, which is another advantage over nylon nets. In summary, the use of Wieland BlueSea® results in healthy fish from environmentally friendly, sustainable aquaculture with a considerably lower carbon foot print as compared to conventional nylon cages.
