Gambusia, If done the right time of the year the EF should work as good as any other method to capture them. In an ideal world we could flip a switch and inventory all your fish. It does not work that way. I think you received the best collection method possible. The report was well written as well as from a company with a great reputation.

If you want more info on smallmouth you can fish for them and run some of the Wr data yourself to increase that sample size and for different times of the year track their growth. Also consider tagging some fo the bass with individual numbered tags. This for sure would add to the big picture of "how are our smallies doing".
