Vegeta: Not til the fish jumps!
Vegeta: It's over.
Simply put, jumping fish is the presence of fish indicated by having one or more fish literally "jumping" out of a source of water (lake, river, etc.), especially when the characters suggest looking for food. These fish often soar two or three times their body lengths straight up before splashing back into the water, for no other reason than to advertise their presence.
In Real Life, most fish do not jump out of the water or, if they do, emerge only an inch or two to catch prey just on the surface. However, this can be used as a visual shorthand, to quickly show not only that there are hungry fish to be caught but also to cut down the time it would otherwise take to see if a body of water actually has any fish in it.
- In Monster Rancher, "Undine's Lake", just when everyone is complaining about a lack of food, some fish jump out of the lake, prompting them to start fishing.
- In Dragon Ball Z, this happens at the end of movie 7. Vegeta even makes a comment about it, after Piccolo breaks the fourth wall (this dialogue wasn't in the original, though).
- Magikarp of Pokémon learns both Splash (which is supposed to mean "hop") and Bounce, both a reference to its jumping ability.
- On Sesame Street, there was a sketch where Ernie and Bert went fishing and Ernie got fish to jump into the boat by calling them.
- MythBusters (2017) took on the Silver Carp (see the Real Life folder below) and investigated if a fish's jump potentially had enough force to kill a water-skier. It turns out a two-pound fish to the face can break your neck, so be careful.
- In one Calvin and Hobbes strip, Calvin is fishing and a fish jumps out of the lake and bites him on the butt. He then reacts with ire when Hobbes asks if the "fish are biting today".
- The Age of Empires series uses jumping fish to indicate fishing locations.
- Several Mario Kart games have tracks with jumping fish that try to throw off your concentration. They don't actually smack into you, but they do distract.
- Fortuna from Star Fox features a large body of water from which giant fish leap to attack you and your wingmen.
- One of the random animations for water hexagons in Age of Wonders 2.
- There are a few levels across the Super Mario Bros. series that feature Cheep Cheeps leaping across the screen in swarms. You can still Goomba Stomp them, but it's tricky since they move so fast.
- Super Mario World has a few levels where Mario has to cross a body of water on the backs of dolphins which are leaping out of it.
- The Chopper robots in the Sonic the Hedgehog series is constantly jumping out of the water — though, of course, those aren't really fish.
- Downplayed in Ace Fishing. The fishes don't jump out of the water willy-nilly, but if your catch doesn't appear out in the surface at least once while you're reeling them in, you can be quite sure that it's not actually a fish.
- In the old NES fishing game The Blue Marlin, marlins and swordfish are the only types of fish that periodically leap out of the water once you've hooked them.
- Similar to their Cheep Cheep brethren noted above, the massive red Blurps from Yoshi's Story will leap from the water in the Jungle Puddle to swallow the baby Yoshi protagonists in one bite.
- In the Strong Bad Email "lures and jigs", Strong Bad causes fish to jump into his boat by singing.
- In a Porky Pig comic, Porky and his nephew Cicero bathe three large, flea-covered dogs in the lake, causing the fleas to scatter. The lake's fish immediately jump to eat the fleas, attracting the attention of nearby fishermen.
- Seen on a Barney Bear cartoon. The fish disappear when a duck flies in to give Barney trouble.
- Theme park example: a pond in Disneyland's Frontierland has mechanical fish that periodically jump.
- Various types of Flying Fish jump out to avoid predators, some of which can reach a height of 6m and travel 400m out of water.
- Salmon are of course known for jumping upstream for breeding, much to bears' delight.
- Yellowtail Kingfish from the estuaries and coastal waters around Australia are a prized sport and eating fish that grows at least 40 cm long and able to jump up to 1 metre above water. It looks similar to this close relative from the coast of California, but can jump even higher.
- Asian Silver Carp are known for jumping uncontrollably out of the water as seen here. Oddly, this is a behavior only found in the invasive population in the US, not in wild or domestic populations in Asia.
- Arowanas are a group of tropical freshwater fishes which are specially adapted to jump straight up from the water and snatch prey - insects, lizards, and even unwary birds or mammals - from low-hanging tree branches.
- As has been shown in numerous Shark Week specials, great white sharks will attack seals by slamming into them from below with such force that both shark and seal will be launched completely out of the water.
