Every winter Ive been looking forward to another great blue cat season. I love chasing them whether its jug fishing or rod & reel. I do catch big blues all year long but I always seem to catch a higher percentage of bigger blues during the winter. Where one 20 pound blue during the summer would make me happy . I may catch 9 or 10 blues over twenty pounds in a day in the winter. Ive always heard that the blue cat fishing is better during the winter and the last four years has proven it to me. The big question I guess is why is theyre a higher percentage of bigger blues caught during the cold-water period? I know there always the stories of winter shad kills that the catfish will gorge on but how does this relate to more bigger fish being caught. Well here is my theory on why I catch a higher percentage of bigger blues. We all know catfish especially those blues are pigs when it comes to eating. Ive always notice that most of the pictures of blues caught with huge stomachs that look like theyre going to explode are usually caught during the winter or early spring months when the water is cold. Ive caught little 3-pound blue cats that when I cut open their stomachs I counted over 30 2 to 3 inch shad in their bellies. Those big blues could probably hold a couple hundred shad in their stomachs. Now when you think of a fishs metabolism the colder the water the slower their metabolism is able to digest food. Therefore my theory on why bluecats have such bigger stomachs during the winter is for one, their pigs and will fit any piece of food that they can fit into their mouth and their slower metabolism makes their stomachs overflow. So now why does this relate to bigger fish being caught during the winter? I simply think that the bigger fish, since they have a larger belly will hold more food and your bait has a better chance of being eaten by a large fish than a smaller one. Its kind of like the big bait equals bigger fish. A big bait doesnt guarantee a bigger fish but simplys keeps the much higher percentage of smaller fish away from your bait. Where a smaller fish says I cant eat another bite those bigger fish can eat just another small shad. I do know this for sure Ive learned to size down my shad or other baitfish during the winter. Ive throw out LOTS of jugs during the winter and shad that are bigger than four inches dont get eaten. The smaller shad are the only ones that usually get eaten. Well I spend too much time thinking about this stuff. What are your thoughts on the subject.
