If you are using fresh roe, the important things are to tie the sacs tight. When you use them you want the roe to "leach" out thru the bag as if it wasn't there. Use plenty of borax on the roe, ( when you think you have enough....add more and be sure it is well coated)and you can store in the fridge for a long time. Depending on the speed of the water, temperature, etc. I would change the roe bag every 15-20 casts and change for sure if you get a hit, or have a fish on briefly....
Leave the fish to rest for a few min., put on a fresh bait and fire away!.Good luck!.........Ortho 8)
