Pictures of Fish Electric Catfish Pictures and Electric Catfish Fishes Kind

Electric Catfish have the ability to produce electric shock of up to 350 volts. They can generate the electric shock using electro plaques of their electric organ. They can be found in the tropical Africa and along the Nile River. Nile fish has been well known in the popular ancient Egyptian cultures, where it has been depicted in mural paintings and other artworks. Electric catfish generally use their electric organ to ward off their predators; however, their electric shock is not known to be fatal to human beings.

Electric catfish is usually a nocturnal fish. They feed mainly on other fish by incapacitating their prey with electric discharges. Although electro-receptive system is widely present in the catfishes but electric catfishes a very well-developed electric organ, which is derived from anterior body musculature and it lines the body cavity. Electric catfishes do not have dorsal fins or fin spines. Instead, they have three pairs of barbels. They can grow up to a size of 100 cm long and a weight of 20 kg.

One female may lay 1400 to 1800 eggs. Their spawning occurs in spring season in river channels and across the interface of freshwater and saltwater. Once, Delta Smelt used to a common fish in Sacramento and San Joaquin rivers estuary; however from 1993, the species have been designated as critically endangered species.

Pictures of Fish Clownfish Fishes Pictures and Clownfish Fishes Kind

Clownfish and Anemone belong to the same subfamily and are native to wide ranges of warm waters of Indian and Pacific Oceans including Great Barrier Reef and the Red Sea. Clownfish shows an overall yellow, red, orange or black colors with white bars or patches on some of the species. Largest species has recorded a length of 18 inches while the smallest one has a length of just 4 inches.

Clownfish feed on undigested matter that otherwise could potentially harm sea anemone while the fecal matters of clownfish provides nutrients to sea anemones. Activity of clownfish generates greater water circulations which helps sea anemone. Clownfish along with certain other species are the only fish that can remain safe from the poison of sea anemones. Clownfish generally remain in a large group. They are very popular species in Reef Aquariums. However, recently, clownfish are also bred in the tanks to reduce the number taken from the wild. As compared to wild-caught fish, tank-bred clownfish are likely to survive more. Clownfish feed on algae, planktons, mollusks and crustaceans.

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 Carp Fishes Pictures and Carp Fishes Kind

Carp is a common name for various fresh water fish . Carp is a very large group of fish originally from Eurasia and Southeast Asia. Carp has long been used as an important food fish for humans. Carp is a very popular ornamental fish in Aquarium and ponds (goldfishes being one of the most popular examples of Carps). As a result, carps have been introduced to various regions.

The most notable and popular ornamental carp is coarse fish that are difficult to hook. In USA, carp is classified as a rough fish. Many of the states have also started viewing the carps as angling fish instead of maligned pest. Carps are considered as the queen of rivers and a stately and subtle fish. In England, carps have been naturalized though earlier the carps were not bred in England. In Australia, scientific studies have proved that carps are the cause of permanent turbidity and loss of submerged vegetation system, with severe consequences for river ecosystems water quality and native fish species.

Pictures of Fish Seahorse Fishes Pictures and Seahorse Shark Fishes Kind

Seahorse is a genus of fish that also include pipefish and leafy sea dragons. About 32 species of seahorse fishes are found in shallow tropical and temperate waters throughout the world. Seahorses prefer to live in sheltered areas such as grass beds, coral reefs or mangroves. Sizes of seahorse fish ranges from very small (dwarf seahorse), about an inch long to those much larger sized seahorses measuring about one-foot long.

Seahorses are bony fish but do not have any scales. They have a thin skin stretched over a series of bony plates arranged in rings throughout its body. Seahorses swim upright unlike their close relative pipefish, which swim horizontally. They are poor swimmers and thus can be mostly found resting at seabeds or coral reefs. Seahorses have long snouts, which makes it possible for them to suck up food. The eyes can move independently of each other much like a chameleon. They feed on small fish, shrimps and plankton (drifting organisms like animals, plants or bacteria). Seahorses are extensively used in Chinese medicines and herbology.
