If I was targeting trophy pike and drilled 5” holes, I’d be in trouble.
Some of the walleye we catch on Saginaw Bay would laugh at an 8in. hole as it went by, lol! And, you can also hook a 30lb+ Laker, or 20lb.+Steelhead, Northern, catfish, etc. etc.. And, a few Sturgeon have been caught, although I've never caught one. Could you get any of them through an 8in. hole? Maybe, if all the stars were aligned and you were a fish whisperer! Yes, usually an 8 in. hole would be sufficient, and a lot of walleye have been landed through them. But, most would be sick to need a bigger hole and not have it!
The small holes ice over infinitely faster. We use 8” for general purposes and 10” pike fishing on thick ice.
ive gotten 5 pound bass, 11 pound and 8 pound pike up 6 inch holes in the past.
8 inches is the perfect size. Anything smaller and you run the risk of losing a big fish at the hole. Anything bigger and it becomes a hazard on the ice. I was jogging to a flag a few years back and stepped in a ten inch hole. My size 9 boot fit right in the hole and I smashed my shin on the ice. I walked away with a nice bruise but it could have been much worse. I've only had one fish I couldn't get through an 8 inch hole and that was more so due to where I hooked the fish and not the size of the hole.
How about a 7lb bass and 3lb crappie? Thats why I use an 8" hole.
The circumference of an 8in hole is ~25". A 28" bass (current state record) with a 25" girth would weigh roughly 16lbs and would still fit (tightly) thru an 8in hole.There was a video a few years back of a couple guys who got a nice pike thru a 6in holeHeres the clip:
will they fit technically yes. but the problem comes when you are playing a fish at the hole trying to get its head up a smaller hole and the hook pops out when you could of more easily got the head up a bigger hole quicker.
You are correct, bigger holes make turning into the hole easier. But the OPs questions seemed more related to fish fitting up the hole.
There is no perfect solution to any fishing scenario. Some people could use 20" holes and still bomb every fish they hook.
I know that guy his name is Eric😂
