There are many variants of fish you can catch depending on the season and weather. You can buy fish bait at Sandy's Tackle Shop to increase the chance caught rare fish. Sometimes your bait will be snagged when the fish take a long time to spawn, and you will get item like Building Stone, Weed, Wood, or Groundbait/Fine Groundbait or even better the Gems (Splosh Lake and Land Fishing Rod only).
When you try to go fishing, the fish will only spawn for 3 times. To reset it, you need to take a nap.
For time efficiency, try to take a nap for 30 seconds. For example: If you take a nap at 10:25, you will wake up at 11:00, but if you try take a nap at 10:31, you will wake up at 12:00.
Some fishes required specific weather (which is very rare) to available to get caught and it occured not for a long time, it is easier to use Land Fishing Rod instead.
