Is a fish a good symbol for a funding organization?

I'm helping a funding organization to make a brochure about their China-projects and they asked me to look at the lay-out of the brochure. They were pretty eager to be as political correct as possible, so they wanted to know whether the symbols they used could not have a bad connotation in China.
I of course asked some of my Chinese friends to look at it, but they could not find anything wrong. Most obvious symbol that was used was the fish, lots of fish were going through the lay-out. Now "yu" has more meaning than only fish, it can also mean wealth or having a lot of money.
Maybe the design was politically correct, but having to much fish in your lay-out might still be the wrong message a funding organization wants to give to its partners.
