I fished a NW Jersey stream today, known for it's potential for wild browns, bows, & brookies. Caught 5 bows nymphing on tan caddis larvae and GRHE's. Four of the bows were dark colored with a very bright red stripe down the side. Two were spilling "milk" from their underside. The fins were not clipped on any fish and they all ran 12-14" in size. Three of the five fish were caught well off the beaten path and good 1/4-1/2 mile away from any road through swampy marsh and thick brambles, so if they were stockies at one point, they definitely migrated to their current lies.

Were these fish stream bred or holdovers?
