What do Dolphins Eat? Dolphins mainly eat fish and squid. Different species are known to prefer different types of food. Mackerels are known to have more fat as compared to squids; therefore certain species of dolphins prefer mackerels to other species of fish. Dolphins also feed on planktons and smaller varieties of fish as well. Herrings and cod also form a part of their diet. Dolphins use a variety of ways to procure food. These techniques vary between species and within particular species as well. Such is their intelligence that dolphins are used for fishery in many countries. A modern format of fishing is practiced in Laguna and Brazil. Here, dolphins indicate the fishermen at the shore the precise moment when they can cast their nets. In turn, dolphins feed on the various fish that escape the nets. At times, dolphins work together in a group and surround smaller fish to procure their food. Sometimes they use their tail to strike certain fish in order to stun them.
Dolphin drive hunting, also called dolphin drive fishing, is a method of hunting dolphins and occasionally other small cetaceans by driving them together with boats and then usually into a bay or onto a beach. Their escape is prevented by closing off the route to the open sea or ocean with boats and nets. Dolphins are hunted this way in several places around the world, including the Solomon Islands, the Faroe Islands, Peru, and Japan, the most well-known practitioner of this method. Dolphins are mostly hunted for their meat; some are captured and end up in dolphinariums. Despite the controversial nature of the hunt resulting in international criticism, and the possible health risk that the often polluted meat causes, thousands of dolphins are caught in drive hunts each year.
How to save dolphins? Saving dolphins is not a difficult task, it only requires some attention from all of us. One of the most important issues that should be addressed is the reduction of the pollution in the oceans which cause thousands of deaths to dolphins. The second issue is related with the accidental deaths caused by fishing nets, specially those deployed by tuna ships. Also the sound pollution should be stopped. Finally the stop of all kind of commercial killing should be avoided. Doing this and educating people about dolphins will help to save dolphins.
December 2nd, 2012 by Ben Volin Editor’s note: The previous updates in this blog appear chronologically. MIAMI GARDENS — The Dolphins put up a good showing in Sunday’s game against the Patriots, particularly on defense. But the offense couldn’t overcome early mistakes or get the ball in the end zone in the second half, and the Dolphins fell 23-16. The Patriots scored their first 17 points off of Dolphins mistakes — a fumbled punt snap by Brandon Fields on his own 12, a roughing the kicker penalty on Jimmy Wilson that gave the Patriots new life and a lost fumble by Ryan Tannehill in his own end. Tom Brady was just 24 of 40 for 238 yards, one touchdown, one interception and a season-low 74.8 passer rating. But Tannehill was inaccurate and off-kilter today, completing just 13 of 29 for 186 yards and a 66.2 passer rating. He had just 130 passing yards until the Dolphins’ final drive. The Dolphins almost made it close in the fourth quarter, but were held to a field goal after reaching the 7-yard line with 8 minutes left. New England then iced the game with an impressive 16-play drive that covered 77 yards and took 7:18 off the clock. The loss — their fourth in five games — drops the Dolphins to 5-7 and makes their slim playoff chances seem even more improbable. Technically they are still in the playoff hunt, but will need to win at least three of their final four games to be in consideration. We’ll have more reaction after post-game interviews with the players. Thanks for stopping by today!
A Dolphin's Habitat Dolphins live in harbors, bays, lagoons, gulfs and tributaries. They do migrate if the water gets cold enough. Also they may migrate if the fish supply and feeding habits change. Some like cold and deeper water than others.
