Brian L, last fall i added 3 Grass carp per acre and followed up with 2 more per acre last spring. These were 14" when they were added. Total of five per acre or 15 GC. Last month i saw 10 swimming together and looked to be in the 25" size range, which makes me wonder if i lost 5 over the past year, or did i just not see the others ? Now, if i had lost those five before the BPW took off and growing then 10 is not enough to control the BPW this coming year. I think this way because the original stocking was with 10 GC. Now i wonder if i should stock another 5 this coming spring? For those that might think an e survey might give me a better idea on how many are there, i have seen where shock survey's may not show all of them in the pond but only a snap shot showing there are GC. Any thoughts on adding additional Crass Carp this coming spring?
