If you do go the Esox route, I would highly recommend tiger musky to avoid any chance of reproduction. However, NP rarely spawn successfully in small ponds but with your luck you'd have the right conditions in your pond. I would also recommend you not stock more than 2 or 3 at most in your 1 acre pond. Keep in mind a pond on average can support about 100 pounds of predators per acre. 2 Tiger musky, 5 years later can weight 30 or 40 pounds combined, that's 30-40% of your predator biomass! This would be the main reason I would recommend you go with thinning out your bass yourself and not letting tiger muskies do it for you. Also, you control what is taken out, where as the tiger muskies control what is taken out. If you are trying to establish GSH, the tigers are gonna mostly eat on them first and the bass second. Just like bass, tigers like GSH over spiny fish. In the case of TJ's pond, it's 4 acres, 4 times the size of your pond. That difference gives a little more room to play with... Unless you have a huge desire to have large Esox species in your pond, a fyke net is a much better options for controlling panfish in a pond. You set it up, check the next day and remove the fish. If you see fish you don't want to remove, you toss them back... Prime
example of the results of using a fyke net. They work quite well on tiny crappie as well... Note, that the large GSF caught was able to be salvaged for display in an aquarium.
