How useful it will be, predatory fish to breed on the Land and sell the catch fresh? The Saarbruecken-based Start-up Seawater Cubes believes: very.
BERLIN taz | The whole sea bass, with the exception of about 400 grams, costs 11,40 Euro, the smoked variant 16,90 Euro. The first 500 fish from the country, were sold before Christmas. Carolin Ackermann sounds a little proud, as she reports about this first success of Seawater Cubes. With the Saarbrücker Start-up, you want to teach farmers the fish and sell Fish. The special feature: The sea fish is grown, far from the coast.
Ackermann, who Founded the company together with a mechanical engineer and an automation engineer. It is self-Finance, Marketing, and sales.
scientists have Long been looking for a good, ecological way to breed fish. The wealth of the seas is running low, several wild stocks is poor. EU fisheries Ministers have, for example, halved the quotas for cod in the North sea and the northeast Atlantic for the coming year are just beginning. At the same time, fish is regarded worldwide as the most important supplier of Protein for the human diet.
Philipp can Inger, an expert from the environmental Association, WWF, explains: "The fish is the more environmentally friendly alternative is the breeding compared to fattening of pigs or cattle often." Because fish are better feed utilizers "are", it would take even less space. The organization for economic cooperation and development, OECD, has estimated that by 2030, nearly two-thirds of all the fish will come on the plate of fish farms. Currently, it is almost every second.
Only this fish comes mostly from Asian underwater farms – elsewhere, aquaculture plays hardly a role. Of him can discourages Inger, however. He wear no Organic certification by naturland or ASC the Aquaculture Stewardship Council, were not bred the animals mostly "sustainable". From the open cages were chemicals, food residues, Fischkot and antibiotics in rivers and seas. It was basically "a good thing", when the wolf will perch in a closed System great.
The offer Container of Seawater Cubes. More than seven years, the founding team has all of the Hochschule für Technik und Wirtschaft des Saarlandes graduates – of-flow, Filter, posture, puzzled and, most recently, a prototype developed, optimized for sea bass and sea bream. The company promises the water again and again, in such a way that it can stay to 99 percent in the circuit. Also it will consume less energy than systems with a similar technology. The result, as Ackermann had had fish products, the "Sashimi-quality". They can be eaten raw. On an area of slightly more than 100 square meters per year can add up to 7 tonnes of sea fish are produced.
250,000 euros is intended to be a system cost. Rainer Froese, a fish expert at the Kiel Geomar Helmholtz centre for ocean research, but discourages "any farmers urged to invest his money in intensive aquaculture". The man could not make by the way. "The risk of technical failures and diseases is great." Fish care is easy, the operation of a highly complex cycle plant "a science". Also, the pressure on the wild stocks become larger. Finally, the sea bass is a predatory fish, the if no green stuff, but usually with other fish in the Form of fish meal and fish oil-fed should be.
"The feed coefficient is 1.2," explains Ackermann. Means: for the animals 1 Kilo of scheduling of meat, you need 1.2 kilos of feed is a special mix for wolf cichlids, which also contained remains from fish processing for the food industry. This is already better than the average. However, Froese remains: "To throw more fish in, comes out." Who wants to ever breed fish, decide for types of Vegetarian eating. Tilapia, for example – even if only to lower sale prices achieved.Rainer Froese, Geomar Helmholtz-Zentrum
"You throw more fish in, out,
Ackermann is not distracted, say, Germany interested far already farmers for the converted ship container. Your goal: Within the next ten years, nationwide 120 Cubes to be delivered and food merchants and restaurateurs of the fish from the country has to offer.Updated Date: 10 January 2020, 10:00
