Was out funfishing one day when we saw a bed....my buddy pitched in to it and caught the fish on the first cast...he unhooked it and put it right back in the water and it swam right directly back to the bed and didnt move....just to see how tight it was stuck to bed i trolled up to it, stuck my rod in the water and rolled the fish over with the tip of my rod....IMO a fish caught off bed and immediately released will still guard a bed as agressively as before
