Today, there was a special day on marine biological research in the natural history museum.
On my way there, I saw a great cormorant flying.
Closer to the museum, moorhens and coots.
No mute swans, though they are there at other times, and a sign warns they may be angry sometimes.
Especially for the marine biology day, there was a small robot submarine in the canal around the museum.
There should be northern pike and other fish species in that canal.
However, it seems that the camera today saw just one fish.
Participating organizations of the marine biology day were:
Center for Estuarine and Marine Ecology
The committee on new and invasive species of the Dutch-Flemish Society for Ecology (NECOV)
Committee on Ecological Water Management (WEW)
Photo and Film Team (OFFT)
Blijdorp Zoo, Oceanium
Biological Committee of the diving association NOB
Later, there will be more entries on this day at this blog.
