Having my neighbor remove 50 to 60 BG from my 1 acre pond each year seems to be keeping their numbers under control, and the pond producing nice BG. I need to evaluate my LMB in that pond since it has been a few years since a winter fish kill. I have seen a few small ones when hand feeding BG. I understand that managing a perennial and diverse ecosystem is more difficult than a single crop of fish, just like managing a multi-species fruit orchard is more difficult than managing a corn field. For me, this is the fun of it. Getting things to a good spot in the YP/SMB pond will be another welcome challenge and learning experience. Hopefully my 10 SMB stockers reproduced on the rock piles I constructed before the pond filled. The YP have reproduced, but I saw only a few egg ribbons. I will sample that pond once a month next year as suggested earlier. BTW - We (my wife) farm annual vegetable crops as a business, but the wildlife habitat and ponds are a hobby.
