Dutch baby sharks

Thursday, June 23, 2016

For the first time it has been established that a shark species reproduces in Dutch waters. Researchers from Wageningen IMARES and Sportvisserij Netherlands write that in the Journal of Fish Biology.

It concerns the starry smooth-hound shark. In the Oosterschelde and the Zeeland Delta in recent years countless young have been seen. It is suspected that they were born in the North Sea. ..

The researchers suspect that school sharks, a much larger species, also reproduce in our waters. …

This week also a petition was launched to enforce better protection for sharks. Sign too, and check out the action page.

This May, not only a young sea eagle in Dutch national park Oostvaardersplassen has been ringed.

Earlier this month, also two eaglets in Zwarte Meer nature reserve were ringed. These two young birds weighed 4 and 5 kilogram respectively. As food, their parents had brought to the nest a northern pike, a bream, seven coots, four great crested grebes, two gadwall ducks and a hare.

New Triassic fossil fish discovery in the Netherlands

Saurichthys fossil from China

Translated from Leidsch Dagblad daily in the Netherlands:

Billfish in Naturalis museum

Leiden – Naturalis has acquired a fossil of a new species which must have lived 200 to 250 million years ago. The billfish-like fish (Saurichthys diannae) was found by amateur paleontologist Herman Winkelhorst in the quarry of Winterswijk.

By Wilfred Simons – 27-5-2016, 17:36 (Update 27-5-2016, 17:36)

At the time, that area was in a coastal zone of the Tethys sea. That these billfish used to live also just offshore in shallow water, is proven by the fact that their eyes pointed upwards.

Winkelhof [sic; Winkelhorst] discovered a “graveyard” of about thirty young fish of the newly discovered species. That indicates that the sea at Winterswijk may have been a breeding ground for young life, like the current Wadden Sea. The amateur paleontologist donated the fossil to Naturalis.

Young shark saved by seal rehabilitation workers

The young Lauwersoog shark

Translated from Blik op nieuws in the Netherlands today:

This Wednesday a beached starry smooth-hound shark was found at the Hoek van Bant, Lauwersoog by employees of the Seal Rehabilitation Centre Pieterburen. In close consultation with Mark de Boer of Rotterdam Zoo the animal was helped back to sea again.

Rehabilitation coördinator Michael Bakker Paiva of the Seal Centre Pieterburen has a very special week: last Sunday, he assisted in the rescue of a harbour porpoise and today he found a beached starry smooth-hound shark. The centre staff were reacting to a report about a dead seal and found the shark in shallow water in the Hoek van Bant, near Lauwersoog.

They had to act quickly, as low tide was starting.

Directly they discussed that with Mark de Boer of Rotterdam Zoo, because if the shark had to be cared for then it would go to Rotterdam.

Fortunately things went well for the animal and with the assistance of biologist Sander van Dijk of the Seal Centre Pieterburen the fish was helped into a bucket of water. Then the animal was freed in deep and calm water near the port of Lauwersoog.

This was a young shark, 85 centimeter. An adult may be 180 centimeter.
