Do Not Mess With Fish 282,

and you thought fish were fun!

screen shot Visdeurbell, well these are, apparently they have trained humans to open fish gates for them! sorry about the translation of the fishes names, the city of Utrecht in the Netherlands has so many dams, canals, and locks as part of that water control system, which is a major problem for migrating fish, many species travel from the Vecht river to the shallower water of the Kromme river in order to spawn, but getting through Utrecht was an obstacle course, until ecologist Mark van Heukelum came up with the Fish Doorbell, or Visdeurbel, the Fish Doorbell starts with an underground camera that anyone can access online,

screen shot Visdeurbell, the bell on the right for watchers to ring if you are live streaming on the web site, the message says 'At the moment 87 people are watching the live stream!' when fish gather near a lock, a user can activate the doorbell, and an operator will open the lock for the fish to pass through, for three years now the system has been running and it appears to be a success, and has gathered a community of "fisherman" around the world who monitor the canals of Utrecht to aid the fish, like birdwatchers, trading sightings of different species of fish with each other, I guess this might lead to a number ding-dong jokes rather that knock-knock jokes! I just hope a local SCUBA diver does not try to have a practical joke by putting a fake non-native fish in the view of the camera! Oh dear, should I have said that?
