In my case $ and broken promises...I was promised success at a sustaining threadfin population and it failed twice. The cost far surpassed the cost of Tilapia and did not provide a fraction of the benefits of Tilapia, IMO. Not even close.
No comparison in my case. Tilapia far surpass them in pond benefits. The two failed threadfin attempts far surpassed the costs of Tilapia stocking for 4 years total and didn't come close to adding the weight to predators, removing algae, adding to pond health, increasing BG populations, and providing some limited sport fishing and eating....not even close in my book.
