I don't see how setting a connection to active can activate datasets, 
but we'll leave that aside for the sake of argument:

There is no need for timers. Every dataset has an AfterOpen event.

Why not use that to populate the fishrecord ?

That's how I do it in all my code. Call Load, and in the AfterOpen event
handler I do whatever is needed.

That's what these event handlers are for, after all.
