I know there is some great YP knowledge on this forum so here goes. This is the 3rd season for our pond. Originally stocked 100 6-8" YP from Jones Fish Hatchery. I don't believe we have caught any of the original stocked fish. All the YP we catch are between 4-6" using jigs or minnows. Is it to early in the process to be concerned? All other species are healthy and growing nicely. Thanks in advance guys.
