Dara (fish)
The dara (''Parakuhlia macrophthalmus'') is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is native to the Atlantic coast of Africa. It is the only species in the monospecific genus ''Parakuhlia''. Description The dara has an oval, moderately deep and laterally compressed body with a steep head, the profile of the head being , a little concave above the large eyes and ending in a short, blunt snout. The mouth is large, set diagonally and has protrusible jaws. The jaws are equipped with many bands made up of villiform teeth which are also on the vomer but there are no teeth on the palate There is a single dorsal fin but it has a deep notch between the spiny portion and the soft-rayed portion. The dorsal fin contains 11 spines in before the notch and 1 spine and 15 or 16 soft rays behind the notch, the anal fin has 3 spines and 16 soft rays. The caudal fin is slightly emarginated. It is mostly silvery in colour, darker on the back, while the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Pellegrin
Jacques Pellegrin (12 June 1873 – 12 August 1944) was a French zoology, zoologist. Biography Pellegrin was born in Paris on 12 June 1873. He worked under zoologist Léon Vaillant (chair of reptiles and fishes) at the ''Muséum national d'histoire naturelle''. From 1897, Pellegrin served as ''préparateur'' at the museum. He obtained doctorates in medicine (1899) and science (1904), and in 1908 was named as an assistant director. After many missions abroad, he became sub-director of the museum in 1937, and replaced Louis Roule (1861–1942) as the chairperson of herpetology and ichthyology. He published over 600 scientific books and articles and scientifically described around 350 new species. He named a number of fishes from the family Cichlidae, such as the genera ''Astatoreochromis'', ''Astatotilapia'', ''Boulengerochromis'', ''Lepidiolamprologus'', ''Nanochromis'' and ''Ophthalmotilapia''. Pellegrin fought with the French Resistance during World War II. He was killed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spawn (biology)
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and amphibious animals reproduce through spawning. These include the following groups: * Bony fishes * Crustaceans (such as crabs, shrimps, etc.) *Mollusks (such as oysters, octopus, squid) *Echinoderms (such as sea urchins, sea stars, sea cucumbers, etc.) * Amphibians (such as frogs, toads, salamanders, newts) * Aquatic insects (such as dragonflies, mayflies, mosquitoes) *Coral, which are living colonies of tiny, aquatic organisms—not plants, as they are sometimes perceived to be. Corals, while appearing sedentary or botanical by nature, actually spawn by releasing clouds of sperm and egg cells into the water column, where the two mix. As a general rule, aquatic or semiaquatic reptiles, birds, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haemulinae
Haemulinae is a subfamily of the Haemulidae and consists of the genera of that family which are regarded as being of New World origin, although they are now widespread. The subfamily is distinguished from the Plectorhynchinae by having a short dorsal fin which contains 13-16 soft rays, as opposed to the long dorsal fin with 17-26 soft rays of the subfamily Plectorhynchinae. Genera The following genera are included in the Haemulinae: * ''Anisotremus'' Gill 1861 * ''Boridia'' Georges Cuvier, Cuvier, 1830 * ''Brachydeuterus'' Gill, 1862 * ''Conodon'' Cuvier, 1830 * ''Emmelichthyops'' Leonard Peter Schultz, Schultz, 1945 * ''Haemulon'' Cuvier, 1829 * ''Haemulopsis'' Franz Steindachner, Steindachner, 1869 * ''Isacia'' David Starr Jordan, Jordan & Bert Fesler, Fesler, 1893 * ''Microlepidotus'' Gill, 1862 * ''Orthopristis'' Charles Frédéric Girard, Girard, 1858 * ''Parakuhlia'' Jacques Pellegrin, Pellegrin, 1913 * ''Pomadasys'' Bernard Germain de Lacépède, Lacépède, 1802 * ''Xenic ...

Smoked Fish
Smoked fish is fish that has been cured by smoking. Foods have been smoked by humans throughout history. Originally this was done as a preservative. In more recent times, fish is readily preserved by refrigeration and freezing and the smoking of fish is generally done for the unique taste and flavour imparted by the smoking process. Smoking process According to Jeffrey J. Rozum, "The process of smoking fish occurs through the use of fire. Wood contains three major components that are broken down in the burning process to form smoke. The burning process is called pyrolysis, which is simply defined as the chemical decomposition by heat. The major wood components are cellulose, hemicellulose and lignin."Ingredients in Meat Products, Properties, Functionality and Applications [] "The major steps in the preparation of smoked fish are salting (bath or injection of liquid brine or dry salt mixture), cold smoking, cooling, packaging (air/vacuum or modified), and storage.

Seine Fishing
Seine fishing (or seine-haul fishing; ) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat. Boats deploying seine nets are known as Fishing vessel#Seiners, seiners. Two main types of seine net are deployed from seiners: ''purse seines'' and ''Danish seines''. A seine differs from a Gillnetting, gillnet, in that a seine encloses fish, where a gillnet directly snares fish. Etymology The word ''seine'' has its origins in the Old English ''segne'', which entered the language via Latin ''sagena'', from the original Greek σαγήνη ''sagēnē'' (a drag-net). History Seines have been used widely in the past, including by Stone Age societies. For example, the Māori people, Māori used large canoes to deploy seine nets which could be over a kilometer long. The nets were woven fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuhlia Caudovittata
The flagtails (' or ' in the Hawaiian language) are a family (Kuhliidae) of centrarchiform ray-finned fish of the Indo-Pacific area. The family consists of about 12 species in one genus, ''Kuhlia''. Most are euryhaline and often found in brackish water, but the genus also includes species restricted to marine or fresh water. Several species are known as Hawaiian flagtails, particularly ''K. sandvicensis'' and ''K. xenura''. Etymology The genus ''Kuhlia'' is named for the German zoologist Heinrich Kuhl (1797–1821). Description The distinctive characteristic of these fish is a scaly sheath around the dorsal and anal fins. The dorsal fin is deeply notched between the 10 spines and the 9 to 13 soft rays. The opercle has two spines, and the anal fin three. Their bodies are compressed and silvery, and they tend to be small, growing to 50 cm at most. During the day, they usually school, dispersing at night to feed on free-swimming fish and crustaceans. Species The current ...

Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Zoologist
Zoology ( , ) is the scientific study of animals. Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and used this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel and many others. The study of animals has largely mov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French People
French people () are a nation primarily located in Western Europe that share a common Culture of France, French culture, History of France, history, and French language, language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily descended from Roman people, Romans (or Gallo-Romans, western European Celts, Celtic and Italic peoples), Gauls (including the Belgae), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norsemen also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such ...
