Merg,
Your advice doesn't go well here as most of the readers are not in the same position as you. Since this is a fishing board, I will put this in fishing terms. Most of us have taken our possession limit. Any additional attempts to fish, even catch and release, could result in serious fines. Those in that are still fishing, do not have as fresh as bait as you do.

You may enjoy catch an release, but there are some problems with continuing this over the long run (I won't go into the moral objects to this, though if some people are right you may pay dearly for this in the end).
First of all, as your bait gets older, you will not catch as many as you have in the past. The ones you do catch, will definitely not be of high quality and will cut horribably. Most of the quality fish will have already been taken by other fisherman. Agian, while new fish may move be available, they will not take your bait unless you are lucky enough to suppliment it with very expense additives.
As you get older, be careful. As some of the older members here may tell you, there are a lot of down river brights that become extremely agressive as you get older. Avoid these at all costs. They cut horribably and are not worth possessing.
On another note, I noticed that you seem to imply that you like to try to catch multiples. These may be fun to catch and release but while they may appear to like your bait, they most likely are cannilbalistic. If you try to take these home they most likely are more interested in eating each other and leaving you hungry.

If you are smart enough to realize that you should take your possession limit and quit fishing, be extremely carefull. Treated badly, your catch could go bad quickly. If you chose wisely and treat it right, your catch can last you a lifetime.
