Pictures of Fish Dogfish Pictures and Dogfish Fishes Kind

Dogfish is a common name for number of small sharks that can be found in in the northeast Atlantic, Pacific and Mediterranean Ocean. In freshwater lakes and rivers, dogfish usually refers to Bowfin family. Dog fishes are known to have lived for many years, even up to 25-30 years. Dogfishes are generally regarded as a nuisance by the fishermen because it tends to latch onto almost anything put in the water including human hands.

Dogfishes are slender and small sharks with a flattened head and a snout tapering to a blunt tip. Their average size is 2.5-3 feet long and larger species of 4-feet and above are also known. They feed on small fish, squids and crustaceans. Dogfishes hunt both alone as well as in groups with other dogfishes.  They have long jaws with low, flat, grinding teeth. They also possess a set of small and very sharp teeth. Population of dogfishes has declined sharply and hence it is illegal to kill them. However, in Britain and especially in the south of England, dogfishes are regarded as delicacy, mostly as a less costly alternative to cods.

Pictures of Fish Danio Fishes Pictures and Danio Fishes Kind

Danio is a genus of fish species that comprises of many of the species of Danionins. The name comes from Bengali word that translates into ‘of the rice field’. Danios are native to fresh water rivers and streams of southeast Asia and are also found throughout the world as aquaculture species. Several species have been recently discovered in remote Islands of Myanmar.

Danios have two pairs of long barbels, which generally have horizontal stripes. Some of the species have vertical bars. Their size ranges from 4-15 cm in length. In the aquariums, they tend to live for 2-3 years while in wilds, they generally do not live for more than a year. Danios mainly feed on crustaceans, insects, worms and planktons in wild. In aquariums, they feed on a variety of foods including frozen food and flakes. They are very sociable and easy to maintain and thus are very popular for keeping in aquariums. Danios should be kept in tanks with water temperature in the range of 18-24 Celsius. They are good at jumping and therefore the lid of tanks should be tight fitting.

Pictures of Fish Cisco Fishes Pictures and Cisco Fishes Kind

Cisco is a salmonid (family of ray-finned fish) fish. They differ from other members of the genus by having upper and lower jaws of approximately equal length. Five endemic species of Laurentian Great Lakes are thought to be of very recent evolution. Cisco species have recently been subjected to lots of research that is being carried out to determine the relationships among the species that have evolved recently.

Ciscoes are extensively explored in commercial fisheries especially in the Laurentian Great Lakes, where deep water forms are considered as the basis of chub fishery. Chub fishery was exclusively based on the various species of Ciscoes. The fishery continues even when the stocks of Ciscoes are falling and other species are spreading through the system. At many places, Cisco species have declined in great numbers. Some of the breeders believe that Ciscoes represent  an incipient species flock. Lots of debates have taken place to  ascertain which were the true species and which were not, particularly due to the facts that some of the species have become extinct.

Pictures of Fish Eulachon Pictures and Eulachon Fishes Kind

Eulachon is a small anadromous ocean fish native along the Pacific Coast of North America from Northern California to Alaska. Eulachon is an important part of the diet of many ocean and shore predators. Besides, it is also used as a prominent source of food item for many people living near its spawning streams. Eulachons are also known by other names such as hooligan, ooligan or candlefish. Candlefish is the name given by early explorers of eulachons who often dried fatty spawning fish and strung on a wick, to be burned as a candle.

Eulachons often spend most of their adult lives in the ocean and return to their native freshwater streams and rivers to spawn. Due to this typical nature, one stream may see regular large runs of eulachons while a neighboring stream may have very few or none. In may happen that a river that  sees large runs of eulachons every year, may all of a sudden witness a year with no returns of eulachons. Eulachon feed mainly on planktons, fish eggs, insect larvae and small crustaceans. Eulachon is an important part of the diet and a valuable trade item for several communities along the Pacific Coast from California to Alaska.

Pictures of Fish European Minnow Pictures and European Minnow Fishes Kind

European Minnow is a species of freshwater fish and member of carp family that can be found throughout most of Eurasia, Great Britain, and from Spain to eastern Siberia. They are predominant in cool streams and well-oxygenated lakes and ponds. They are known for moving in large schools (groups of hundreds and thousands of fishes). Although they are sometimes called as Eurasian Minnows but the name is misleading because they occur only in fewer parts of Asia.

European minnow is a small, slender and dark-colored fish with blunt snout and small scales. Their belly is cream to pearl colored and changes to red in males during spawning season. Their size ranges from 8 to 10 cm long. They are common in fast flowing freshwaters and well-drained vegetated ponds. They are rarely used as aquarium fish despite the breeding in captivity being feasible. In aquariums, they should be kept in cold and fresh waters with a good supply of oxygen and a reasonable water current. In Scotland and Germany, European minnows are rarely found, where they have been declared as legally protected species.

Pictures of Fish Bull Shark Fishes Pictures and Bull Shark Fishes Kind

Bull Shark is a shark that is widespread all over the world in warm and shallow waters along coasts and in rivers. The name bull shark comes from stocky shape, broad and flat snout and aggressive and unpredictable behavior. Since the bull sharks dwell in shallow waters, they are more dangerous to human beings than any other species of sharks. Three shark species that are most likely to attack human beings include bull sharks, tiger sharks and great white sharks. They can travel far up the rivers and thus are responsible for the majority of shark attacks on humans.

Bull sharks can tolerate fresh water unlike most of the other marine sharks. Due to its wide range and diverse habitats, there are many names for bull sharks such as Sundarbans or Ganges shark in India, Zambezi shark or simply Zambi in Africa and Nicaragua shark, among other. Bull shark is found in different geographical locations throughout the world and can travel long distances. Bull sharks are large and stout animals that can reach up to 7 feet in length and weigh up to 90 kg. They feed on fish, rays, dolphins, turtles, birds, mollusks and crustaceans.

Pictures of Fish Antarctic Icefish Fishes Pictures and Antarctica Icefish Fishes Kind

Antarctic Icefish is a largely endemic, dominant fish in the cold continental waters surrounding Antarctica. Majority of the Antarctic Icefish live at seawater temperature -2 and 4 degree centigrades but some of the sub polar species inhabit waters that may be as warm as 10 degree centigrades around New Zealand and South America.

Antarctic Icefish have evolved a variety of interesting physiological and biochemical adaptations with which they can survive in cold and stable seawater temperatures of Southern Ocean, many being able to survive in the freezing and ice-laden waters. Most notable physiological aspect of Antarctic Icefish is they have only 1% hemoglobin unlike other animal species that have up to 45% hemoglobin in their blood. They can survive without large parts of hemoglobin due to high oxygen contents of cold waters of southern ocean and also due to the fact that oxygen is absorbed and distributed directly by the plasma. Antarctic Icefish is considered to the only marine fish species flock.

Pictures of Fish Goldfish Fishes Pictures and Goldfish Fishes Kind

Goldfish is one of the most common aquarium fish and water garden fish. It is a small member of carp family of fish. It is one of the earliest domesticated fish. Goldfish are small, colorful, inexpensive and popular pond fish. They can survive in ponds as long there is enough oxygen and the pond does not freeze solid. They are usually classified as coldwater fish. They live in unheated aquariums.

Selective breeding of goldfish has produced several color variations over the years, with few being far away from the original golden color of the domesticated fish. Goldfish can lose their golden color by varying the spectrum of light under which they are kept. Goldfish can grow up to 22 inches in length and around 10 pounds in weight. Household goldfish kept in bowls can live up to 6-8 years. There are several varieties of goldfishes such as calico, celestial eye, comet, lionhead, bubble eye, butterfly tail and black moor, among others. Besides, several new varieties are also created by selective breeding.

Antarctic Cod Fish Pictures and Antarctic Cod Fishes Kind

Antarctic cod fish is famous for producing antifreeze glycoprotein that allows it to survive in the ice laden waters of southern sea surrounding Antarctic sea. They are also known as antarctic toothfish. Antarctic cods have a heartbeat rate of once every six seconds. Scientists are doing research on antarctic cods for cardiac medicines especially in human conditions involving low heartbeats or patients with the conditions of hypothermia.

They are very large fishes and can be caught in the waters below 2000 meters depth. Fully grown antarctic cod fishes are grayish in color, weigh around 135 kg and have a length of more than 2 meters. The flesh of antarctic cod is white and is rich of high oil content. Although the name is antarctic cod but they do not belong to cod family. The taste is very similar to cod and that is why the name antarctic cod. They generally feed on various types of fish. However, they are also known to eat almost anything including the remains of penguins caught by seals and orca on the surfaces.

Pictures of Fish Alaska Blackfish Fishes Pictures and Alaska Blackfish Fishes Kind

Alaska Blackfish, found only in Alaska and eastern Siberia, is a fish that can grow up to 7-inches in length. It has an elongate and cylindrical shape with dark olive-brown coloration. They can be normally found in the densely vegetated areas of lowland swamps, ponds, rivers and lakes. Sluggish and bottom-dwelling fish, Alaska Blackfish use their large pectoral fins to paddles through the vegetation in search of food. They capture their prey with a quick dart. They feed on larvae of insects such as midge and mosquitoes.

Alaska natives love to eat these fishes and feed them to their dogs. Ease of capture and great abundance makes them as principal source of food and as a subsistence fish. They catch them in fall and freeze them to use over winters. Alaska Blackfish can survive extreme cold weather by moving deep up to a depth of 7 to 8 meters when the surface becomes solid ice. They can be easily distinguished from other fishes by their paddle-like pectoral fins and tails, tiny ventral fins and a broad flat head.
