pike opens the second saturday in May on island lake. (before venturing into any new water, always read the regs!) You will catch a bunch of perch and small panfish probably fishing with bobbers and worms. For something more exciting learn how to cast spoons to catch pike. The fish this time of year will be moving towards the warmest water closest to the deeper parts of the lake.
If you are into getting serious about fishing, Id suggest just doing a load of googling about how to target whatever species you are looking to catch. Its a life long learning process that gets more and more detailed the more serious you take it. You can decide to be a worm and bobber fisherman and that suits some people just fine to go out in a boat toss out a worm and wait for a bite while relaxing, or you step your game up a bit and make things more involved, but also some would argue have more fun doing it.
Or you can be stupid like me and spend all of your expendable income to stare at panoptix for 8 hours straight chasing laketrout around.
I was also once a kid throwing spoons for pike from a tinner too. We all start somewhere.
Let us know how you fare!
