My humble opinion

 

Contact Bob Lusk at Pond Boss, Bob & Pond Boss are probably the best management consultants in the world. 

Thanks Catt. Been talking to them too.

I'm starting to think I may need some new Genetics in here too.To my knowledge it was only stocked once way back.T here's no other way fish can get in,except for the once in a long time heavy rain that will overflow the creek into it.

But we have so many fish already I'm hesitant.
