Aside from tagging each individual fish with something like RFID, it may be easier to measure average fish density over time and estimate the count. Though accounting for fish size may be problematic.

Some sort of one way gate that you sweep through the pond? May be impossible though depending on the shape of the pond. Are the fish being fed at one specific spot or something? Maybe that could be used somehow.

Some type of holographic or synthetic aperture sonar system might work but that may be too complicated or expensive for your requirements.

Edit: Also phased-array type sonar.

I have a little experience in trying to count fish using a camera, and imaging software. More details would be helpful. We were counting fish in a tank lighting was a big issue. For other applications we have RFID tagged them and used that to count the number of fish through a passage.

It's much easier to count them moving through a gate of some sort. But that may be a bit hard to arrange in a quiescent pond. :)
