The Dutch Fish Doorbell is live for the season.

https://visdeurbel.nl/en/

The Fish Doorbell in Utrecht in the Netherlands is an interactive online Citizen Science tool:

The Fish Doorbell is an initiative of the municipality of Utrecht, Hoogheemraadschap De Stichtse Rijnlanden (HDSR), and Mark van Heukelum of Dutch Wallfish. The municipality of Utrecht and HDSR manage and maintain the water quality in the Vecht, Kromme Rijn, and Utrecht’s canals.

Every spring, thousands of fish swim through the Oudegracht in Utrecht, searching for a place upstream to lay their eggs. But the Weerdsluis is often closed. You can help the fish continue their journey! If you see a fish, press the doorbell. This alerts the lock operator to open the lock.


Pressing the doorbell button also snaps a picture of whatever’s in the live camera field, helping the researchers record fish species and numbers.

The time displayed is Central European Time (UTC +1) until March 30, when Central European Savings Time (UTC+2) begins; the Fish Doorbell will continue through mid-May.

I have only lived in the Netherlands since August, but I have heard the word Dutch quite a bit without any sort of pejorative overtones.

I am Dutch, and it is not considered a slur at all.
It is not linguistically the 'correct' word (it would in fact be the natural cognate for 'German'), and the pedants among us will not hesitate to point this out, but it is the correct & accepted word in English and as such it is the word pretty much anyone would use to self-describe when speaking English.

(As a matter of fact Deutsch/Duits/Diets were on occasion used to describe the language spoken in the Netherlands up until the nineteenth century, which is why in the national anthem stadhouder William of Nassau is called what in current usage translates to 'of German blood'...)

I love the fish doorbell, and I'm glad that it's back in season again.
