Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Duméril of Paris. His wor ... [...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] |

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mysis
''Mysis'' is a genus of mysid crustaceans in the family Mysidae, distributed mainly in the coastal zone of the Arctic and high boreal seas. Several species also inhabit northern freshwater lakes and the brackish Caspian Sea. Fifteen species are recognized. Body lengths range from . The freshwater taxa of the genus have been referred to as "glacial relicts", and they comprise four closely related species, most of which also live in brackish water. ''Mysis relicta'' is a freshwater species from boreal lakes of Northern Europe, also present in the Baltic Sea. ''Mysis salemaai'' is another North European and Baltic Sea taxon. ''Mysis segerstralei'' is a fresh- and brackish-water species of the Eurasian and North American Arctic and sub-Arctic. The North American lakes, including the Great Lakes, are inhabited by ''Mysis diluviana''. Various species of Mysis are found in lakes of the South Swedish highlands, like Lake Sommen, that were never connected to the sea or the Baltic Ice La ...

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 ...

Tuna
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna (max length: , weight: ) up to the Atlantic bluefin tuna (max length: , weight: ), which averages and is believed to live up to 50 years. Tuna, opah and mackerel sharks are the only species of fish that can maintain a body temperature higher than that of the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimming pelagic fish – the yellowfin tuna, for example, is capable of speeds of up to . Greatly inflated speeds can be found in early scientific reports and are still widely reported in the popular literature. Found in warm seas, the tuna is commercially fished extensively as a food fish, and is popular as a bluewater game fish. As a result of overfishing, some tuna species, s ...

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.

Taxa Named By Pieter Bleeker
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
