Labeo Bata
''Labeo bata'' (Assamese: ভাঙন, ) is a fish in genus Labeo. It is a native fish to India and Bangladesh. Description It is a popular game fish and is popular for its taste. Its maximum length is . It eats protozoa, algae, and tiny fishes. It is a slow-moving fish, so with any active and aggressive it will be nervous. The age and growth of Labeo bata (Ham.) was studied by the analysis of annuli found on the scale and by length-frequency distribution. The fish attained lengths of 131, 194, 236, 277, 314, 341 and 364 mm at the end of the 1st, 2nd, 3rd, 4th, 5th, 6th and 7th years of life respectively. The increase in length of scale bears a constant relationship with the increase in length of fish. The growth rate of the fish was found high during the 1st and 2nd years, and decreased gradually afterwards till the 7th year. Both sexes showed more or less similar growth rate. The seasonal growth curve was chiefly influenced by feeding intensity in fishes of 1st year cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Buchanan-Hamilton
Francis Buchanan (15 February 1762 – 15 June 1829), later known as Francis Hamilton but often referred to as Francis Buchanan-Hamilton, was a Scottish surgeon, surveyor and botanist who made significant contributions as a geographer and zoologist while living in India. He did not assume the name of Hamilton until three years after his retirement from India. The standard botanical author abbreviation Buch.-Ham. is applied to plants and animals he described, though today the form "Hamilton, 1822" is more usually seen in ichthyology and is preferred by Fishbase. Early life Francis Buchanan was born at Bardowie, Callander, Perthshire where Elizabeth, his mother, lived on the estate of Branziet; his father Thomas, a physician, came in Stirling, Spittal and claimed the chiefdom of the name of Clan Buchanan, Buchanan and owned the Leny estate.

Labeo
''Labeo'' is a genus of carps in the family Cyprinidae. They are found in freshwater habitats in the tropics and subtropics of Africa and Asia. It contains the typical labeos in the subfamily Labeoninae, which may not be a valid group, however, and is often included in the Cyprininae as tribe Labeonini. If the Labeoninae are accepted as distinct, Labeonini is the name of the tribe in this subfamily to which the labeos belong. If the Labeonini are considered a tribe of the Cyprininae, the labeos are placed in subtribe Labeoina. The labeos appear fairly similar to the " freshwater sharks" of the genus '' Epalzeorhynchos'', which is also part of the Labeoninae (or Labeonini), but is not very closely related. Labeos are larger, and have a more spindle-shaped body, as they are mostly free-swimming rather than benthic like ''Epalzeorhynchos''. Their mouths look very different, too; they have a pronounced rostral cap, which covers the upper lip except when feeding. The lips are exp ...

Fish Of Bangladesh
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolution, evolve through the Paleozoic, diversifying into many forms. The earlie ...
