In South Holland province more than 50 volunteers monitor incoming migration of migratory fish with frame nets. In addition to observations of elvers and three-spined sticklebacks also a lot of valuable information about other fish is collected. In early April the volunteers met several one-year-old vimba breams in their frame nets in the New Waterway near Maassluis. Observations of the vimba bream in the Netherlands are scarce, especially so of young animals.

The vimba bream owes its Dutch name, blauwneus [blue nose] to the blue-gray fleshy nose of adult animals. It was originally a Central European species that by digging the Main-Danube Canal and helped by transfers has expanded into Germany to the Rhine Valley. The first observations of the vimba bream in the Netherlands date back to 1989, when a three-year-old fish was caught in the Lower Rhine.
