Best fishing bait for cold temperature?

Jigs work good for Bass. The Bream really become lethargic like most fish do in the Winter, but they still bite.

I usually get most of my answers about fishing at , here is an article I found that may be useful to you. Hope this helps!
Some may question whether this is the reason bass do not bite after a cold front passes through, but few question the fact that bass become inactive behind a cold front.
And fewer still question whether it is hard to get a bite behind a cold front.
When bass become inactive they tend to hold tight to cover. And on blue bird days they hold tight to cover. If the bass were previously feeding shallow, they will move to nearby shallow cover and hold tight to it.
If they were feeding in deeper water, they will move to a nearby ledge and hold tight to it. A front may cause a bass to move 50 feet but not several hundred feet.
And mark this well: Just because the bass are inactive does not mean they will not bite. Instead, it means they will not chase down a lure to strike it.
When bass are inactive, we have to put our lures right in front of their noses. This is true whether we are talking about shallow fish holding in brush, or deeper fish holding tight to a drop-off inside a creek channel. If the fish are holding shallow, the best bait to use is a jig-and-pig tossed tight to cover.
If there is buck brush in the area, throw the jig-and-pig right in the middle of each clump of buck brush. If there is a lot of buck-brush, concentrate on the brush in deeper water, and on the outside edge of the brush line.
As a general rule, the outside edge of buck-brush will hold more fish than the shallower brush nearer the shore.
If the fish are holding tight to a drop-off we use the same lure. We position the boat over the the creek channel, we pitch a jig-and-pig up onto the flat then slowly hop it over the drop-off.
We expect the bite to come as the lure goes over the side of the drop-off. We use black/blue pig-and-jigs in dingy water and pumpkinseed baits in clear water.
More often than not we will be using a 1/4th-ounce jig with a matching trailer.
If there are shallow fish, we expect to get bit when the bait: (1) hits the side of a stump, (2) hops parallel along a log, (3) in the thickest part of vegetation, (4) underneath the base of a tree, or (5) along the side of a large rock.

When I ice fish for cats I like to use fresh dead or live minnows place just off the bottom almost as fishing for pike.One way to find cats is to look for a high o2 deeper hole or a channel to find cats under ice.And believe it or not I do use blood bait once I find some good cats.If fishing open waters I look for high current high o2 area’s with breaks or timber.These pockets may hold o2 better and on rivers you may find your dream fishing hole for cats may stack up by the hundreds in a good hole in rivers during the coldest months.
For gill’s I like to use mousies wax worms or spikes on small jigs!
