Derbio in North Sea – 24/12/12
Fisherman Jan de Vries has been at sea all his life, but this species he had never seen. That is probably true, because the derbio is very rare in the North Sea. The fish was caught 50 miles to the northwest of Texel by the ship TX29, with Johnny Drijver as its skipper. Fisherman Fred Wiering recognized this was a special fish and kept it separate. He gave the animal to Ecomare curator Arthur Oosterbaan to find out whether this really was a derbio.
The derbio owes its Dutch name, “vorkmakreel”, literal translation “fork mackerel”, to the special shape of its tail. It is a southern species, occurring on the West African coast, in the Mediterranean Sea and the Western European coast to Scotland and the North Sea. It is a coastal-dwelling fish. Near the sea surface it hunts small fish, small crustaceans and molluscs. In Dutch waters, it has been seen only a few times, including in the Oosterschelde.
