The game feature several rods, items, and upgrades. Cat Goes Fishing, sell your catch, and upgrade Once you use your cash to upgrade your boat, you will be able to fish farther and deeper. As you continue to sell your catch, you can spend your earnings on new rods and fun perks like bombs, rockets, and repellants. Once this is done enough without catching a fish, the bait withers up and is ultimately rendered useless. Larger fish will inevitably take bites out of the smaller fish and bait that you have hooked. As you progress, you’ll learn to steer past some species of fish to better attract larger fish with more complicated bait. There are a total of three sizes of bait that allow you to catch progressively larger fish. Learn to catch different types of fish based on the size of the bait you use.
