Being from Michigan, here's what I do. Keeping them in the livewell while you're fishing is fine as long as you have plenty of water for the # of fish, you need to keep them alive. As soon as you leave the lake get them in a cooler with ice and wait until the next day to clean them. Rinse the fillets a couple of times then put them in a bowl and cover with water. I don't add salt to the water. Leave them in the fridge at least overnight, changing out the water if you think about it. Give them another good rinse before you package them or fry them. I vacuum pack my fillets. I lay the fillets out on a bath towel, cover them with another towel and dry them as much as possible. Then I vac pack them. Works good for me, others may have different opinions.
The older I get the more I realize the therapeutic benefits of fishing
