Different Types Of Saltwater Fishes

As you all know that i belong to a fisherman family. My grandfather was a fisherman. He was really famous in Gadani for his fishing techniques. Today i am going to write about different types of fishes so you can learn about them easily.

Commercial Fish

A commercial fish is a fish that is caught in order to be sold and eaten. About 65 million tonnes of fish are caught every year. Cod, mackerel and tuna make up almost half the entire catch in the world.

Mackerel

The mackerel has a slender, well-rounded body, marked with irregular black lines. Adults eat crustaceans and small fish. Young fish eat planktonic crustaceans and fish larvae. Mackerel move north in spring and summer, and south in winter. In winter, Mackerel are one of about 50 species in the family Scombridae. In summer, a medium size female may produce as many as 450000 eggs, shed in no particular place, which float until they hatch about 4 days later.

Yellowfin Tuna

The yellowfin tuna has long pectoral fins, small yellow finlets behind dorsal and anal fins and yellow marking along its sides. Its body is typically spindle shaped. Yellowfin tuna eat fish, crustaceans and squid. Like most species of the family Scombridae, they make seasonal migrations. Spawning takes place at any time of the year in the tropics and in late spring and summer elsewhere. Every year, females are believed to produce at least two batches of over a million eggs.

Cod Fish

The cod is a major food fish. It lives in the northern waters of Atlantic and Pacific Oceans. The Cod belongs to the cod fish family, which also includes the pollock and the haddock. The cod has five fins. The colour of the fins varies from grey to red to brown or black with the upper parts marked with many small dark spots.

Flounder

The Flounder is the name of a group of saltwater fish. It has greatly compressed body with both eyes on the same side of the head. The side of the flounder facing up takes on the colour of the bottom of the sea where the fish lives. Flounder live on sandy muddy bottoms of bays and along the shores of most seas.

Salmon

The Salmon is long narrow fish. It has small fleshy fins on its back, behind the man dorsal fin. It lives in cool waters. It spends most of its adult life at a sea but migrates to rivers to spawn. Young Salmon returns to the sea once they reach at certain size.

Salmon Fish

Haddock

The Haddock is an important food fish that belongs to the codfish family. A black line along each of its sides and a black spot just back of its head distinguishes the Haddock from other codfish. Haddock live in the western North Atlantic Ocean. In the eastern North Atlantic, they are found off northern Europe, Great Britain and Iceland. They are abundant in the North Sea. Haddock weighs about 3 pounds (1.4 kilograms ) and are about 2 feet (61 centi meter ) long

Fish of Coastal Water And The Open Ocean

Some saltwater fish live along the coasts of continents. Others live far from shore in the open ocean, though many of these fish also swim close to the shore from time to time. Both coastal and open ocean species are shown here.

Flying Fish

The Flying Fish is a silvery fish with large pectoral fins that can be spread out like wings. It swims rapidly towards the surface of the water. Then it flicks its powerful tail to leap out of the water and glides though the air. There are about 50 different species of flying fish.

Flying Fish

Sailfish

The Sailfish is a large open ocean fish, with an extra long upper jaw shaped like a spear. Sailfish use their bills to slash and stun prey, which they can raise like sails. Sailfish sometimes fold dorsal fins into grooves on their back to improve streamlining while swimming. Sailfish are the fastest fish in the sea, reaching a speed of 109 kilometer per hour.

Herring

The herring is a silvery fish with a narrow body that tapers to a thin ridge along its abdomen. The herring has a single dorsal fin and its pelvic fins are well set back on its abdomen. The scales on its fins are easily rubbed off. Herring form huge shoals in the open sea and along the coast.

Halibut

The Halibut is one of the largest and the most important of the flatfish. It has a flat body, with both eyes on the same side of its head. Its eyes lie in the right side, which is dark brown. The left side is white.

HogFish

The hogfish’s thick lips protrude slightly and its forehead curves steeply above the mouth. The tips of the dorsal and anal fins are pointed. Colouration is variable in this species, but males tend to be more intensely coloured than females. Hogfish eat molluscs, crabs and sea urchins.

Sawfish

The Sawfish is a large shark like ray. It has a flat snout which narrow edged with saw like teeth. The sawfish uses its saw to dig out animals from the sea bed or to slash at shoals of fish. It lives in warm shallow waters.

Blowfish

Tetraodontidae is a family primarily marine and estuarine fish. The family includes many familiar species which variously called puffers, balloonfish, swellfish, toadfish, and toadies. They are morphologically similar to the closely related porcupinefish, which have large conspicuous spines. The scientific name, Tetraodontidae, refers to the four large teeth, fused into an upper and lower plate, which are used for crushing the shells of crustaceans and mollusks, and red worm their natural prey.

Whale

The Whale is a large marine mammal. There are about 75 species of whales, divided into two main groups. The toothed whales include sperm whales, killer whales, pilot whales and narwhales. They feed mainly on squid and fish. All the toothed whales swallow their prey whole. The baleen whales include blue whales (the largest mammal that has ever existed on earth), grey whale and the humpback whale. They feed by filtering zooplankton from water.

Marlin

The Marlin is a large fish with upper jaws that extent into a long spike. It uses the spike to stun small fishes. The marlin’s tail is deeply forked.

Shark

The shark lives mainly in warm seas throughout the world. It varies greatly in size from about 13 centimetres to about 12 metres long. It is carnivore. It eats live fish including other sharks. It is a powerful predator. It can swim through the water at a speed of up to 50 kilometer per hour. There are about 350 species of Sharks.

Dolphin

The Dolphin is a small toothed whale. Like alla whales, it is a mammal, not a fish. Mammals, unlike fish, feed their young with milk that is produced in the mother’s body. Also, unlike fish, it has lungs. It ranks among the most intelligent animals along with chimpanzees and dogs. There are 32 species in the dolphin family. The dolphin is found in oceans. It has a beaked snout. It lives in large schools and hung fish, which it grips with its many pointed teeth.

Tarpon

The Tarpon is a large fish with big shiny scales. The last ray of the tarpon’s dorsal fin is very long. Tarpons have teeth on the roof of their mouths and on their tongues as well as on their jaws. They are fast swimmers and are famous for making huge leaps out of the water. Some tarpons grow up to 2.5 meters long.

Sunfish

The Sunfish is the name given to several kinds of fish. The most common type of sunfish is the ocean sunfish. It has quite a circular body and large dorsal and anal fins which are almost apposite to each other. Ocean Sunfish can grow up to four metres long l, but their average size is about 90 centimetres. They are often found in the open ocean, sometimes at depths of 350 metres. Ocean sunfish feed on jellyfish , sea gooseberries and young fish.

Zebra Danio

The Zebra fish aur Zebra Danio, Danio rerio, is a tropical sold under the trade name Zebra Danio, and is also an important model organism in scientific research.

Ray

They Ray has a wide flattened body and a long tail. It swims by flapping its broad pectoral fins up and down. It feeds on invertebrates on the sea bed. There are several species of rays. The giant manta ray is over six metres long. The stingray wields its tail with the great speed and force to drive the spine into its victim. It has sharp poisonous spines on its tail for defence. The electric Ray stunts its prey with electric shocks of 70 to 220 volts, sufficient power throw a man on the ground.

Barracuda

The Barracuda is a fierce slender fish with a long lower jaw and many large sharp teeth. The largest Barracuda grows to three metre long. Barracuda strike at any shiny objects that move. There are 21 species of Barracudas in the world.

Fish of Coral Reefs

Hundreds of kinds saltwater fish live in warm shallow waters around coral reefs. Many of them are among the most beautiful in the world. Fish of coral reefs differ greatly in appearence and in many ways. As these fish are beautiful to look at, are kept in home Aquariums.

Angelfish

The angelfish has a thin oval body and long pointed fins. It also has stripes or patterns on the body and patches of vivid colours. It lives mainly around coral reefs in warm tropical seas. Its popularity with aquarium keepers makes it the most familiar cichilds. In its natural habitat, its compressed body, marked with dark vertical stripes, and extended thread like fins keep it well concealed in cloudy plant filled water.

Queen Angelfish

The Queen Angelfish is very similar to the butterflyfish, except it has a characteristic spine near each gill cover. It has a deep slim body, a blunt snout and greatly enlongated lobes, and dorsal and anal fins that extends past the tail fin.

Grouper

The grouper is a large sea bass. Some of the biggest groupers are up to four metres long and can weigh over 300 kilograms. They lie in wait for other fish between rock coral caves. Groupers move slowly and are easily caught with fishing rod or spear.

Moorish Idol

The Moorish Idol is a kind of surgeonfish. It has a very flattened body, bold, broad, vertical , black and yellow stripes edged with creamy white. It has a long anal fin and a tall dosrsal fin that tapers to a curving point. It has a narrow snout with a bold orange patch and horn like knobs over eyes.
