Clupeiformes is the order of ray-finned fish that includes the herring family, Clupeidae, and the anchovy family, Engraulidae. The group includes many of the most important forage and food fish.
Herring are forage fish, mostly belonging to the family of Clupeidae.
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep-sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout.
Atlantic herring is a herring in the family Clupeidae. It is one of the most abundant fish species in the world. Atlantic herrings can be found on both sides of the Atlantic Ocean, congregating in large schools. They can grow up to 45 centimetres (18 in) in length and weigh up to 1.1 kilograms (2.4 lb). They feed on copepods, krill and small fish, while their natural predators are seals, whales, cod and other larger fish.
Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. Some animals that use this method of feeding are clams, krill, sponges, baleen whales, and many fish. Some birds, such as flamingos and certain species of duck, are also filter feeders. Filter feeders can play an important role in clarifying water, and are therefore considered ecosystem engineers. They are also important in bioaccumulation and, as a result, as indicator organisms.
Arripis is a genus of marine fishes from Australia and New Zealand, known as Australian salmon, kahawai and Australian herring. They are the only members of the family Arripidae. Despite the common name, Australian salmon are not related to the salmon family Salmonidae of the Northern Hemisphere, just as Australian herring are not related to herring of the Northern Hemisphere, but belong to the order Perciformes of perch-like fishes. Australian salmon were named so by early European settlers after their superficial resemblance to the salmoniform fishes.
Sprat is the common name applied to a group of forage fish belonging to the genus Sprattus in the family Clupeidae. The term also is applied to a number of other small sprat-like forage fish. Like most forage fishes, sprats are highly active, small, oily fish. They travel in large schools with other fish and swim continuously throughout the day.
Knightia is an extinct genus of clupeid bony fish that lived in the freshwater lakes and rivers of North America and Asia during the Eocene epoch. The genus was erected by David Starr Jordan in 1907, in honor of the late University of Wyoming professor Wilbur Clinton Knight, "an indefatigable student of the paleontology of the Rocky Mountains." It is the official state fossil of Wyoming, and the most commonly excavated fossil fish in the world.
Kissing gouramis, also known as kissing fish or kissers, are medium-sized tropical freshwater fish comprising the monotypic labyrinth fish family Helostomatidae. These fish originate from Mainland Southeast Asia, the Greater Sundas and nearby smaller islands, but have also been introduced outside their native range. They are regarded as a food fish and they are sometimes farmed. They are used fresh for steaming, baking, broiling, and pan frying. The kissing gourami is a popular aquarium fish.
The Atlantic menhaden is a North American species of fish in the herring family, Clupeidae.
Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs.
The Australian sprat is a sprat fish whose habitat ranges in the waters surrounding Australia including Tasmania. It is a pelagic fish which is found in anti-tropical, temperate water. It is a part of the Clupeidae family. Other members of the Cluepeidae family also include herring, menhaden, sardines as well as shads. It is currently a relative unknown species of Sprat compared to the other members of the family. In total, there are five different types of True Sprats. What makes Australian Sprats different from the rest is their location and appearance. Sprattus Novaehollandiae have a dark blue back and a protruding lower jaw. They are found in the Southern regions of Australian such as lower Victoria and Tasmania were there are colder climates. On average, Australian Sprat grown up to 14 cm and live in the range of 0–50 meters deep in the ocean. They will lay between 10,000 and 40,000 eggs per year and live for approximately 5–7 years. Other names for the Australian Sprat include Clupea Bassensis and Meletta Novaehollandiae.
The stoplight loosejaws are small, deep-sea dragonfishes of the genus Malacosteus, classified either within the subfamily Malacosteinae of the family Stomiidae, or in the separate family Malacosteidae. They are found worldwide, outside of the Arctic and Subantarctic, in the mesopelagic zone below a depth of 500 meters. This genus once contained three nominal species: M. niger, M. choristodactylus, and M. danae, with the validity of the latter two species being challenged by different authors at various times. In 2007, Kenaley examined over 450 stoplight loosejaw specimens and revised the genus to contain two species, M. niger and the new M. australis.
Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by filter feeding. They include particularly fishes of the order Clupeiformes, but also other small fish, including halfbeaks, silversides, smelt such as capelin and goldband fusiliers.
Due to the higher density of sea water than air, the force exerted by the same velocity on an organism is 827 times stronger in the ocean. When waves crash on the shore, the force exerted on littoral organisms can be equivalent to several tons.
Aquatic feeding mechanisms face a special difficulty as compared to feeding on land, because the density of water is about the same as that of the prey, so the prey tends to be pushed away when the mouth is closed. This problem was first identified by Robert McNeill Alexander. As a result, underwater predators, especially bony fish, have evolved a number of specialized feeding mechanisms, such as filter feeding, ram feeding, suction feeding, protrusion, and pivot feeding.
Clupea is genus of planktivorous bony fish belonging to the family Clupeidae, commonly known as herrings. They are found in the shallow, temperate waters of the North Pacific and the North Atlantic oceans, including the Baltic Sea. Two main species of Clupea are currently recognized: the Atlantic herring and the Pacific herring, which have each been divided into subspecies. Herrings are forage fish moving in vast schools, coming in spring to the shores of Europe and America, where they form important commercial fisheries.
The Araucanian herring is a fish species in the family Clupeidae. It is an epipelagic fish, silvery below and dark blue above, which schools in coastal waters off the west coast of South America. It ranges along the Chilean coast from Valparaiso south to Talcahuano. It schools at depths from 0 to 70 meters in nearshore areas.
Sardinella tawilis is a freshwater sardine found exclusively in the Philippines. It is the only member of the genus Sardinella known to exist entirely in fresh water. Locally, they are known in Filipino as tawilis.
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
