Amblygaster Leiogaster
''Amblygaster leiogaster'', the smoothbelly sardinella, also known as blue sardine, blue sprat, bluebait, is a reef-associated marine species of sardinella in the herring family Clupeidae. It is one of the three species of genus ''Amblygaster''. It is found in the marine waters along Indo-West Pacific regions towards south western Australia. The fish has 13 to 21 dorsal soft rays and 12 to 23 anal soft rays. It grows up to a maximum length of 23 cm. The flank is gold in fresh fish but becomes black while preservation. Belly is more rounded and scutes are not prominent. It is rather closely resemble ''Amblygaster clupeoides'', but the latter has very few lower gill rakers than Smoothbelly sardinella. The fish feeds on minute organisms like zooplankton.

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sardinella
''Sardinella'' is a genus of fish in the family Clupeidae found in the Atlantic, Indian and Pacific Ocean. They are abundant in warmer waters of the tropical and subtropical oceans. Adults are generally coastal, schooling, marine fish but juveniles are often found in lagoons and estuaries. These species are distinguished by their ranges and by specific body features, but they are often confused with one another. Fish of the genus have seven to 14 striped markings along the scales of the top of the head. The paddle-shaped supramaxilla bones are characteristic; they separate ''Sardinella'' from other genera and their shapes help distinguish species. They have paired predorsal scales and enlarged fin rays. Species There are currently 24 recognized species in this genus: * ''Sardinella albella'' (Valenciennes, 1847) (White sardinella) * ''Sardinella atricauda'' ( Günther, 1868) (Bleeker's blacktip sardinella) * ''Sardinella aurita'' Valenciennes, 1847 (Round sardinella) * ''Sardine ...

Clupeidae
Clupeidae is a family of ray-finned fishes, comprising, for instance, the herrings, shads, sardines, hilsa, and menhadens. The clupeoids include many of the most important food fishes in the world, and are also commonly caught for production of fish oil and fish meal. Many members of the family have a body protected with shiny cycloid (very smooth and uniform) scales, a single dorsal fin, and a fusiform body for quick, evasive swimming and pursuit of prey composed of small planktonic animals. Due to their small size and position in the lower trophic level of many marine food webs, the levels of methylmercury they bioaccumulate are very low, reducing the risk of mercury poisoning when consumed. Description and biology Clupeids are mostly marine forage fish, although a few species are found in fresh water. No species has scales on the head, and some are entirely scaleless. The lateral line is short or absent, and the teeth are unusually small where they are present at all. Clupe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amblygaster Clupeoides
''Amblygaster clupeoides'', the bleeker smoothbelly sardinella, blue pilchard, sharp-nosed pilchard, or sharpnose sardine, is a reef-associated marine species of sardinellas in the herring family Clupeidae.

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...

Amblygaster Sirm
''Amblygaster sirm'', the spotted sardinella, also known as the northern pilchard, spotted pilchard, spotted sardine, and trenched sardine, is a reef-associated marine species of sardinellas in the herring family Clupeidae. It is one of the three species of genus ''Amblygaster''. It is found in the marine waters along Indo-West Pacific regions from Mozambique to the Philippines, and towards north Taiwan and Japan to the far east of Australia and Fiji. It is a widely captured commercial fish in Sri Lanka, where the fish is known as "Hurulla" in Sinhala language. The fish has 13 to 21 dorsal soft rays and 12 to 23 anal soft rays. It grows up to a maximum length of 27 cm (10.6 in). The distinctive feature of spotted sardinella from other two relatives is the presence of 10 to 20 golden spots along the flank. The color of spots may change into black after preservation. Belly is less rounded and scutes are not prominent. The fish feeds on minute organisms like copepods, lar ...

List Of Common Commercial Fish Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. It is situated in the middle of Indian Ocean. Because of being an island, Sri Lanka has many endemic freshwater fauna, as well as thousands of marine and brackish water fauna. Fishing is the way of life of most of coastal community. So, the marine fish fauna gives a greater commercial value to the country's economy, as well as well being of the coastal people. Marine fish are strictly different from freshwater counterparts due to high salinity of sea water, which they live. Also, they are larger than most freshwater species and rich in proteins. There are about 100+ species of common commercial fish around the country. Crustaceans such as, crabs, lobsters, prawns, and squids, cuttlefish, and sea cucumbers also added to this list instead of fish types due to their high value commercially. i.e. - All Sinhala words are typed by "SININETN" truetype font style of Singreesi software.

Fish Described In 1847
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
