Stocking ideas for 50 000 gallon ponds

[William]

I am currently digging / setting up two 50 000 gallon ponds and i am looking for stocking ideas



They will most likely contain saltwater since I have better access to saltwater on the property but one of the could be setup for freshwater.

I am planning to keep tilapia in one of them. We have a invasive strain here that do very well in saltwater and can be found in costal waters,

I am looking for ideas about what to keep in the other. Preferabel ideas that work with saltwater as that will be cheaper to maintain but I am interested in freshwater as well. Whatever i stick they need to do well with limited filtration/water movement since the ponds will have standing water with about 10% replaced on a dialy basis.

One idea I have been playing have been pacu and arapaima but i would like to hear what other ideas you guys might have
