New Fodder Gives Bigger Fish

13.10.2004


It’s cheaper, and it enables quicker growth and bigger fish. These are the key characteristics of a new fodder in fish farming, which will replace the traditional dry fodder. The raw material is simple: Fish waste.



Fish offal is a high-grade raw material with a low price. We want to use this to make the industry grow," says Oistein Baekken, manager of GellyFeed Ltd.

We are acquiring capital and the industry is showing a great deal of interest in applying this future-oriented concept both to cod farming and salmon farming.


Contrary to the previously used dry fodder, GellyFeed allows more food substances in the fodder to remain in the body of the fish, instead of passing straight through it and into the water, where it may create environmental problems.

Tests show that the growth of salmon may be up to 15 percent higher with GellyFeed than with regular dry fodder. Using the new fodder, a fish farming plant that produces 675 tons of cut salmon will be able to produce an additional 100 tons of cut salmon a year," Baekken says. When the fish grows faster, it will also get bigger during the same period, and this increases the marked price.

Flexibility is another advantage. Contrary to dry fodder, there is no need for additives like oil or starch in order to produce the fodder. Only maritime raw materials are needed. Fish offal from fat fish such as herring and mackerel are excellent salmon fodder, rich in energy. Offal from white fish such as haddock, saithe and cod offer protein-rich fodder for farmed cod.

GellyFeed is a result of ten years of research and development. It started with the RUBIN foundation, continued in Hydro and ended up in GellyFeed Ltd.

The development of GellyFeed has involved research and new knowledge in the chemical treatment of the pellet, in terms of nutrition and veterinary sanitation. The National Veterinary Institute has carried out several lab tests to verify that the processes will satisfy the EU requirements. With funds from the Research Council of Norway we have been able to carry out feeding experiments that demonstrate the excellent performance of the fodder, Baekken says. GellyFeed Ltd holds a patent in Norway and has applied for patent in 33 other countries.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
