John McClelland (doctor)
Sir John McClelland (1805–1883) was a British medical doctor with interests in geology and biology, who worked for the East India Company. In 1835 he was sent on a mission (Tea Committee) to identify if tea could be grown in north-eastern India along with Nathaniel Wallich and William Griffith. This mission ran into troubles with the members of the group. McClelland was appointed 1836 as the secretary of the "Coal Committee", the forerunner of the Geological Survey of India (GSI), formed to explore possibilities to exploit Indian coal. He was the first to propose hiring professional geologists for the task. He was also involved in surveys of forests and his reports led to the establishment of the Forest Department in India. He also served as an interim superintendent of the Calcutta Botanical Garden from 1846 to 1847 and was editor of the ''Calcutta Journal of Natural History'' from 1841–1847. Legacy McClelland is commemorated in the name of the mountain bulbul, ''Ixos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of India
Fishing in India is a major sector within the economy of India contributing 1.07% of its total GDP. The fishing sector in India supports the livelihood of over 28 million people in the country, especially within the marginalized and vulnerable communities. India is the third largest fish producing country in the world accounting for 7.96% of the global production and second largest producer of fish through aquaculture, after China. The total fish production during the 2020-21 is estimated at 14.73 million metric tonnes. According to the National Fisheries Development Board the Fisheries Industry generates an export earnings of Rs 334.41 billion. Centrally sponsored schemes will increase exports by Rs 1 lakh crore in FY25. 65,000 fishermen have been trained under these schemes from 2017 to 2020. Freshwater fishing consists of 55% of total fish production. According to the Ministry of Fisheries, Animal Husbandry, Dairying, fish production increased from 7.52 lakh tonnes in ye ...
