18.09.2018 | Cultured Thornback ray pops up in Wadden Sea

Exactly 285 days after the release of a Thornback ray from our hatchery in Utrecht in the Oosterschelde, the fish was cought in the Wadden Sea. This is mentioned on Twitter by fisherman Piet Bakker on 12th September. The catch implicates a big success for the project 'Sharks and rays back in the North Sea', with Blue Linked as coordinator in fish culture. Dozens of Thornback rays have already been released with the aim to monitor growth and survival of the cultured fish in the wild.

Here you can read the press release of the special catch by World Wildlife Fund (in Dutch).

On 14th October 2017 our project 'Sharks and rays back in the North Sea' reaches an important milestone. The Thornback rays that are cultured in our hatchery since May last year, are released into the wild in the Oosterschelde (the Netherlands). Our staff and student trainees have been working for months on end to meet this moment. We are very proud with the results!

31.08.2017 | Ray-update

A lot of progress has been made in the project 'Sharks and rays back to the North Sea'. The 300 Thornback rays show a steady growth, they are tagged and preparations are carried out to release the fish in the Oosterschelde (Zeeland, the Netherlands).

27.04.2017 | Workshop WWF Impact Ventures

With great enthusiasm the participants of the first workshop of WWF Impact Ventures (24-26 April 2017 in Zeist, the Netherlands) boost their nature conservation projects to a higher level (see news item 28.03.2017). Michaël Laterveer, director of Blue Linked (left, in front), was one of them.

The diversity of the 17 participants and 5 tutors is reflected by the countries they represent, e.g. Brazil, Mexico, Malaysia, Syria, Bonaire, Hungary, Switzerland, the Netherlands, Ecuador and Uganda.

After a period of two weeks, we can assess the first results of the culture of turbot larvae (Scophthalmus maximus) in the Experimental fish fry hatchery of Blue Linked.

Using innovative culturing techniques, we have obtained unexpected results. An important link in the chain of traditional aquaculture methods of feeding fish larvae, can be skipped. This is a breakthrough in aquaculture.
