Any particular way I should go about increasing my stamina? Is it simple cardio or are there any particular exercises I should perform? Playing 2 on 2 hockey over a couple hours gets exhausting
Thanks for the help.

Everything from jogging, sprints, plyometrics, swimming, rowing, other sports, hills and biking could be great ways to improve your stamina in any sport especially hockey.
Your main focus should be on training that mimics hockey functionality movements and cardio. Such as sprinting, stairs/hills, rowing. Quick, high intensity, short burts (for the most part).
Yet the Soviet who dominated from the 60s to the 90s in the hockey world believed in cross training. Jogging far distances would improve leg strength, balance and long distance cardio to have you last longer in games. They believed weight training, plyometrics and other sports would improve your functionality, muscle strength and balance that would all indirectly improve your cardio and game.
I have done extensive research and practices on training for years... message me if you wish to talk more about your training
I'm not seeing loafing on the couch watching hockey and Arrested Development marathons so this won't work for me . . .

i find the p90x workout a good combination of strength and cardio workouts. im currently one month into the program and ive definitely noticed that my overall fitness has improved. it also has a more cardio oriented program too. it does take a big commitment though bc its 6 days a week and workouts range from 1 to 1.5 hours (also the cost of the workout cds and equipment).
Playing all the pickup I can manage has really helped my game. I last a little longer month by month, and the more I skate hard and get off, the better I get at it.
A lot of experts will say don't ride a bike because it'll make your hips less flexible, but so long as you're not playing pro I think you'll be fine. One drill my coach would always have us do in college (club, of course) was to hop on the spin bike, and go 30 seconds as hard as possible then go light for 30 seconds, repeated for half an hour. When you get better at this try going for 45 seconds or up to a minute, then taking just as much time off for an hour. You'll notice results pretty quickly if you do this a few times a week.
HIIT's, and plyometrics.
