Sardine
Sardine and pilchard are common names for various species of small, oily forage fish in the herring suborder Clupeoidei. The term "sardine" was first used in English during the early 15th century; a somewhat dubious etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant. The terms "sardine" and "pilchard" are not precise, and what is meant depends on the region. The United Kingdom's Sea Fish Industry Authority, for example, classifies sardines as young pilchards. One criterion suggests fish shorter in length than are sardines, and larger fish are pilchards. The FAO/ WHO Codex standard for canned sardines cites 21 species that may be classed as sardines. FishBase, a database of information about fish, calls at least six species pilchards, over a dozen just sardines, and many more with the two basic names qualified by various adjectives.

Canned Sardines
Sardines (also known as pilchards) are a nutrient-rich, small, oily fish widely consumed by humans and as forage fish by larger fish species, seabirds and marine mammals. Sardines are a source of omega-3 fatty acids. Sardines can be canned, pickled, smoked, or eaten fresh. The term ''sardine'' was first used in English during the early 15th century, and may come from the Mediterranean island of Sardinia, around which sardines were once abundant. The terms ''sardine'' and ''pilchard'' are not precise, and what is meant depends on the region. The United Kingdom's Sea Fish Industry Authority, for example, classifies sardines as young pilchards. One criterion suggests fish shorter in length than are sardines, and larger ones pilchards. The FAO/WHO Codex standard for canned sardines cites 12 species in the Order of Clupeiformes that may be classed as sardines, including Atlantic herring (''Clupea harengus''), and brisling sardine (''Sprattus sprattus''); FishBase, a comprehensive ...

Forage Fish
Forage fish, also called prey fish or bait fish, are small pelagic fish that feed on planktons (i.e. planktivores) and other small aquatic organisms (e.g. krill). They are in turn preyed upon by various predators including larger fish, seabirds and marine mammals, this making them keystone species in their aquatic ecosystems. The typical ocean forage fish feed at the lower trophic level of the food chain, often by filter feeding. They include particularly fishes of the order Clupeiformes (herrings, sardines, shad, hilsa, menhaden, anchovies, and sprats), but also other small fish, including halfbeaks, Atheriniformes, silversides, Smelt (fish), smelt such as capelin and goldband fusiliers. Forage fish compensate for their small size by forming shoaling and schooling, schools. Some swim in synchronised grids with their mouths open so they can efficiently filter plankton. These schools can become immense Shoaling and schooling, shoals which move along coastlines and Fish migration, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoaling And Schooling
In biology, any group of fish that stay together for social reasons are shoaling, and if the group is swimming in the same direction in a coordinated manner, they are schooling. In common usage, the terms are sometimes used rather loosely. About one quarter of fish species shoal all their lives, and about one half shoal for part of their lives. Fish derive many benefits from shoaling behaviour including defence against predators (through better predator detection and by diluting the chance of individual capture), enhanced foraging success, and higher success in finding a mate. It is also likely that fish benefit from shoal membership through increased hydrodynamic efficiency. Fish use many traits to choose shoalmates. Generally they prefer larger shoals, shoalmates of their own species, shoalmates similar in size and appearance to themselves, healthy fish, and kin (when recognized). The oddity effect posits that any shoal member that stands out in appearance will be preferen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epipelagic Fish
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 marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of . About 98% of the total water volume is below , and 75% is below .#Moyle, Moyle and Cech, p. 585 Marine pelagic fish can be divided into coastal (inshore) fish and oceanic (offshore) fish. Coastal fish#Coastal pelagic fish, Coastal pelagic fish inhabit the relatively shallow and sunlit waters above the continental shelf, while #Oceanic fish, oceanic pelagic fish inhabit the vast and deep waters beyond the continental shelf (even though they also may swim inshore). Pelagic fish range in size from small coastal forage fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are associated with ocean currents and with the availability of food in different areas at different times of the year. The migratory ...

Slender Rainbow Sardine
The slender rainbow sardine (''Dussumieria elopsoides'') is a small, subtropical, salt water fish of the Indian Ocean and the South China Sea which was first described by Bleeker in 1849. ''Dussumieria hasselti'' and ''Dussumieria productissima'' are synonyms for this same fish. It is a round herring of the family Clupeidae. Until the 1980s in the eastern Mediterranean slender rainbow sardines were frequently confused with the rainbow sardine (''Dussumieria acuta''). Wangratana (1980) demonstrated the differences between ''Dussumieria acuta'' and ''Dussumieria elopsoides'', while Whitehead (1985) and Randall (1996) showed that ''Dussumieria elopsoides'' does occur in the Mediterranean. Morphology * Size: 8 cm. to 18 cm. * Color: silvery on the sides darkening to bluish grey on the back, and lightening to almost white on the underside. * Shape: The slender rainbow sardine has an elongated body, with round belly and a pointed nose. The single dorsal (back) fin is sli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Sardine
The rainbow sardine (''Dussumieria acuta''), also known as common sprat, dwarf round herring, rainbow herring, and sharpnosed sprat, is a bony fish important to aquaculture and commercial fisheries. Description The color of the rainbow sardine is iridescent blue with a bit of shiny gold or brass line below, which quickly fades after death; the hind margin of the tail is broadly dark. The fish has a w-shaped pelvic scute; an isthmus tapering evenly forward; and more anal fin rays. There are 14 to 18 anal soft rays. The maximum length recorded is 22 cm. Distribution and habitat Marine and estuarine species, the rainbow sardine can be found in Indo-Pacific regions such as the Persian Gulf (and perhaps south to Somalia), Bangladesh, Pakistan, India, Sri Lanka and Malaysia to Indonesia (Kalimantan) and the Philippines. The species now also occurs in the Mediterranean, having invaded as a Lessepsian migrant through the Suez Canal. See also * Sardine * Slender rainbow sardine '' ...

Tin Can
A steel can, tin can, tin (especially in British English, Australian English, Canadian English and South African English), or can is a container made of thin metal, for distribution or storage of goods. Some cans are opened by removing the top panel with a can opener or other tool; others have covers removable by hand without a tool. Cans can store a broad variety of contents: food, beverages, oil, chemicals, etc. In a broad sense, any metal container is sometimes called a "tin can", even if it is made, for example, of aluminium. Steel cans were traditionally made of tinplate; the tin coating stopped the contents from rusting the steel. Tinned steel is still used, especially for fruit juices and pale canned fruit. Modern cans are often made from steel lined with transparent films made from assorted plastics, instead of tin. Early cans were often soldered with neurotoxic high-lead solders. High-lead solders were banned in the 1990s in the United States, but smaller amounts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sardonyx
Onyx is a typically black-and-white banded variety of agate, a silicate mineral. The bands can also be monochromatic with alternating light and dark bands. ''Sardonyx'' is a variety with red to brown bands alternated with black or white bands. The name "onyx" is also frequently used for level-banded (parallel-banded) agates, but in proper usage it refers to color pattern not band structure. Onyx, as a descriptive term, has also been incorrectly applied to parallel-banded varieties of alabaster, marble, calcite, obsidian, and opal, and misleadingly to materials with contorted banding, such as "cave onyx" and "Mexican onyx". Etymology ''Onyx'' comes through Latin (of the same spelling), from the Ancient Greek (), meaning or . Onyx with pink and white bands can sometimes resemble a fingernail. The English word "nail" is cognate with the Greek word. Varieties Onyx is formed of chalcedony bands in alternating colors. It is cryptocrystalline, consisting of fine intergrowths of t ...

Sardis
Sardis ( ) or Sardes ( ; Lydian language, Lydian: , romanized: ; ; ) was an ancient city best known as the capital of the Lydian Empire. After the fall of the Lydian Empire, it became the capital of the Achaemenid Empire, Persian Lydia (satrapy), satrapy of Lydia and later a major center of Hellenistic Greece, Hellenistic and Byzantine Greeks, Byzantine culture. Now an active archaeological site, it is located in modern day Turkey, in Manisa Province, near the town of ''Sart, Salihli, Sart''. History Sardis was occupied for at least 3500 years. In that time, it fluctuated between a wealthy city of international importance and a collection of modest hamlets. Early settlement Sardis was settled before 1500 BC. However, the size and nature of early settlement is not known since only small extramural portions of these layers have been excavated. Evidence of occupation consists largely of Late Bronze Age and Early Iron Age pottery which shows affinities with Mycenaean Greece and ...
