Any ideas for a Koi Fish Pond Re-opening celebration?

Question

I'm re-posting this question to try and get more responses! Thanks for your help!
-----------------------

At my job, we are having a re-opening of a newly created Koi Fish pond. We are planning to have a "Feed the Fish" type day with the kids in the area - and were wondering if anyone has ideas for this event?
We already have fish-type giveaways, and will be letting each child help feed the fish - but...how else could we implement the idea of Koi fish in the celebration?
(There will be kids of all ages there)

Thanks!

You could have a clown make baloon fish. See photo in link below. I would ask them to us red or gold baloons to look more like Koi.

An idea would be to have a drawing for people to put the fish in the pond. It could just be a symbolic pouring a bucket of pond water with a fish in it, into the pond.

Have a Koi in a fish bowl and have a photographer take portraits of people with the fish. Print and sell them at the event.
