Because they don't get caught up and killed in the mesh of large fishing nets
Dolphins move up and down. Fish move mostly in a straight line.
Dolphins have lateral line other than a fish.
Most dolphins live in groups. That makes it easier to hunt. When they find a school of fish, they chase it to a shallow place. Then they swarm out into a line. Then the fish are trapped. They are caught by a line of dolphins. They do not chew with their teeth. They sallow their prey whole.
Captivity is a very boring lifestyle for a dolphin. They are forced to perform tricks for food. In the wild dolphins feed on live fish, however, in captivity they are fed dead fish. In a lot of cases dolphins have never seen shore line or the ocean floor, so being locked in a concrete tank is extremely stressful for them. Captivity reduces a dolphins lifespan, as said by the IWC.
Dolphins often work together to hunt by surrounding a school of fish. The fish are then trapped, and any that try to escape go right towards the dolphins. They may also blow bubbles (which oddly enough, terrifies the fish) and they won't dare to cross that "line." Instead, they try to jump over the bubbles above the water's surface. Because they are surrounded by dolphins, they jump right into their mouths. Often times, dolphins may simply hunt alongside each other (for example, if they are looking for crustaceans or fish under the sand). In that case, they don't work as a team, but they are close together.
Barring currents, catching a fish or hooking on something it will hang perpendicular to the earth.
The techniques of netting, harpooning, and pole-and-line fishing used by early fishermen were eventually replaced by more efficient methods of catching fish.
You don't necessarily have to catch fish to improve your fishing rod. You can just cast your line than bring it back. But if you do it the long way (By catching fish like the game intended) It will take MANY fish.
Bottle nosed dolphins live in the carribean :) :) :) :) :) XD
The fish only hit it once and there's no tricks. hope this helped! :)

In Harvest Moon DS they can be found by Catching 50, 100, 500, fish etc. They can also be found by casting your line in a variety of places such as your watering hole, your duck pond and the Hot Springs.
