I don't think northern pike would do well in Louisiana's warm climate. Chain pickerel would survive OK. However, this pond is very muddy and both species are very much site feeders, I doubt chain pickerel would do well either and with as over populated as the bass are, the chain pickerel would struggle to make a dent but could actually increase the problem through competition for the limited resources in the pond. Stocking fatheads into a pond that already has adult bass in it is for the most part a waste of money. Just a quick snack that will not last more than a week if that. The addition of structure will certainly help some BG to survive but with many hungry bass mouths, it will only go so far. I think the mentality of the angling club needs to change for an affect to occur. They need to start keeping small bass. Every crappie caught should be kept as well.
