Kaluga Sturgeon
The kaluga (''Huso dauricus''), also known as the river beluga, is a large predatory sturgeon found in the Amur River basin. With a maximum size of at least 1,000 kg (2,205 lb) and 5.6 m (18.6 ft), the kaluga is one of the biggest of the sturgeon family. Like the slightly larger beluga, it spends part of its life in salt water. Unlike the beluga, this fish has 5 major rows of dermal scutes and feeds on salmon and other fish in the Amur. They have gray-green to black backs with a yellowish green-white underbelly. The kaluga has been hunted to near extinction for its valuable roe. Despite constant anti-poaching patrols, poachers still continue to catch the fish. In Russia, illegally fishing for kaluga anywhere in the Amur River is felony punishable by law. However, kalugas are known to have an aggressive nature, and instances of them toppling fishing boats and drowning fishermen have been reported, although no concrete evidence exists of them assaulting or hunti ...

Johann Gottlieb Georgi
Johann Gottlieb Georgi (31 December 1729 – 27 October 1802) was a German botanist, naturalist and geographer. A native of Pomerania, Georgi accompanied both Johan Peter Falk and Peter Simon Pallas on their respective journeys through Siberia. During 1770-1774 he travelled on its behalf to Astrakhan, the Urals, Bashkir, the Barabinsk steppe, the Kolyvanskoe silver mines (to assess the ore content), Altai, Tomsk, Irkutsk, Baikal, and Dauren. In 1783 he became an academician of the Russian Academy of Sciences in St Petersburg. Georgi was particularly interested in the Baikal region. Based on collections from far eastern Russia, in his 1775 publication ''Bemerkungen einer Reise im Russischen Reich im Jahre 1772'', Georgi provided the first botanical descriptions of many of the region's flowering plants, among them the Baikal skullcap (''Scutellaria baicalensis''). Many of these plants and herbs were later collected by European botanists in China, and thereafter became rare sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sturgeon
Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the ..., and are descended from other, earlier Acipenseriformes, acipenseriform fish, which date back to the Early Jurassic period, some 174 to 201 million years ago. They are one of two living families of the Acipenseriformes alongside paddlefish (Polyodontidae). The family is grouped into four genera: ''Acipenser'' (which is paraphyletic, containing many distantly related sturgeon species), ''Huso'', ''Scaphirhynchus,'' and ''Pseudoscaphirhynchus''. Two species (''Adriatic sturgeon, A. naccarii'' and ''Dabry's sturgeon, A. dabryanus'') may be extinct in the wild, and one (''Syr Darya s ...

Salmon
Salmon () is the common name for several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the family (biology), family Salmonidae, which are native to tributary, tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen. Salmon are typically fish migration, anadromous: they hatch in the gravel stream bed, beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run ma ...

Felony
A felony is traditionally considered a crime of high seriousness, whereas a misdemeanor is regarded as less serious. The term "felony" originated from English common law (from the French medieval word "félonie") to describe an offense that resulted in the confiscation of a convicted person's land and goods, to which additional punishments including capital punishment could be added; other crimes were called misdemeanors. Following conviction of a felony in a court of law, a person may be described as a felon or a convicted felon. Some common law countries and jurisdictions no longer classify crimes as felonies or misdemeanors and instead use other distinctions, such as by classifying serious crimes as indictable offences and less serious crimes as summary offences. In the United States, where the felony/misdemeanor distinction is still widely applied, the federal government defines a felony as a crime punishable by death or imprisonment in excess of one year. If punishable by e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
