The fish species, Labeo rajasthanicus was first described from Jaismund Lake in western Rajasthan region, India, based on a single specimen and has never been reported since its first description in 1970. The taxonomic status of the fish has not been stable due to the conflicting opinion among several authors either as a valid species or as a synonym of L. boggut. The present report redescribes the species L. rajasthanicus based on the specimen collected from its type and other adjoining localities, with confirmation of its taxonomic status as valid species and designation of a neotype as the holotype specimen is no longer available. Morphometric and molecular data, distinguish this species from its congeners under genus Labeo, namely L. gonius, L. boggut and L. dussumieri. Analysis of the morphometric and meristic data as well as truss measurements of all the four species confirmed its identity. Among all the morphometric and meristic characters, anal fin rays showed significant d...

Edad y crecimiento de la carpa mayor de la India Labeo rohita (Cypriniformes: Cyprinidae) de los ríos tropicales de la cuenca Ganga, India. Labeo rohita is a member of the Indian major carp species and originally an inhabitant of the Ganga river network in India. It is among the top ten aquaculture species of the world. Since there is a lack of information on the growth pattern of the wild populations of this species, this study aimed at evaluating the pattern of age and growth, to support the development of effective management plans. A total of 1 082 samples of L. rohita were obtained from May 2009 to July 2012 in six drainages of the Ganga basin. Scales of the fish were used to determine the age and growth by analyzing the annual rings growth. Out of six populations, a maximum 8+ age classes were recorded from two rivers (Betwa and Sharda). The back-calculated lengths at 8+ age class ranged from 86.22cm to 91.66cm. However, for the rest of rivers up to 7+ age classes were recorded. Among growth parameters, specific rate of length increase (C l) and specific rate of weight increase (C w) showed decreasing trend, and three distinct life stages of L. rohita were recorded based on growth constant data (C lt). Analysis of variance (ANOvA) of the back-calculated length data set of six populations indicated a significant difference (p<0.05). All three populations showed significant variation in length attainment during 1+ and 3+ age groups, while two populations showed significant variation in length attainment during the 2+ and 7+ age classes. Additionally, analysis of age frequency at different length intervals indicated that with increase in age class, number of fish samples was reduced. Since the pattern of life history traits of L. rohita have not been attempted in the recent past; therefore, this study will guide fisheries biologists about the current stock structure of this fish across different spatial scale of the Ganga basin.
Systematic notes on some cyprinid fishes collected from Kasargod district of Kerala, India
Egyptian Journal of Aquatic Biology and Fisheries
Fishes of the family Cyprinidae include carps, barbs, minnows, etc. They are the most diverse and prevalent group of freshwater species distributed in the aquatic bodies of India and nearby countries. In Kerala they predominate in freshwater capture fisheries. Most of the cyprinids are economically important as ornamental and food fishes. Taxonomic studies conducted on cyprinid species of Kerala state are scarce; no detailed systematic studies were done on these fishes of Kasargod district in Kerala, India. During this study a detailed survey was conducted on various cyprinoid fish species of Kasargod district. Taxonomically important features such as meristic counts and morphometric characters were analyzed and compared with their congeners. Twenty species of cyprinids were collected during the study period. These species belong to thirteen genera (Barilius,
The Indian Major Carp, Labeo rohita, is a geographically widespread and economically important food fish species in tropical freshwater of India and adjacent countries. We studied the lengthweight relationships of 1 033 specimens collected from the main channel of Ganga river and its five major drainages from March 2009 to July 2012. The length of males ranged from 16 to 92cm (females: 16 to 94cm). The growth is allometric positive (b>3) for males, females and pooled sexes. The coefficient of determination (r 2) in males ranged from 0,978 to 0,989 and for females from 0,958 to 0,985. Data from field populations are scarce and our results will be useful in the management and conservation of L. rohita populations in its natural range.
THREATENED FISHES OF THE WORLD: Labeo bata (Hamilton, 1822) (Cypriniformes: Cyprinidae)
Croatian Journal of Fisheries, 2015
Minor carp Labeo bata is an endangered fish species in Bangladesh. This fish is one of the commercially and nutritionally valuable food fish in Asian countries including Bangladesh, India and Pakistan. L. bata is an important target species for small scale fishermen in Bangladesh who use a variety of traditional fishing gears. However, natural populations are seriously declining due to loss of habitat, siltation in the river basin, indiscriminate killing of fry and fingerlings, water pollution by industrial and domestic waste, agrochemicals and overexploitation. This paper recommends the sustainable conservation measures of this endangered fish species in Bangladesh and neighboring countries.

Puntius nelsoni, a new species of the family cyprinidae, is distinguished from its congeners by the following combination of characters: body and fins yellowish; a narrow bluish green mark present on summit of occiput; a thin black band present outer to operculum; barbels short and never reach orbit; head wide and deep; snout shorter; vent located away from ventral fin origin; caudal peduncle long; scales between lateral line and dorsal fin 5 ½ and pre dorsal scales 9. Systomus chryseus, new species, differs from its relative species in having an unusually elongated body, golden to yellowish golden color on flanks, pectoral, pelvic and anal fins orange red; pectoral fin long and its tip reaches origin of ventral fin; lateral line scales 29-30 and pre dorsal scales 11. Systomus rufus, new species, differs from its congeners in having a deeper body; dorsal fin situated nearer to caudal fin base than snout tip and a little behind ventral origin; dorsal fin green and other fins red; 11-12 pre dorsal scales, 30 lateral line scales and 6½ scales between lateral line and dorsal fin base. The new species of fishes are described and compared with its related species

Journal of entomology and zoology studies, 2016
The Objective of the current study was to find out the diversity of fishes of Chambai dam located in District Karak K.P.K, Pakistan. Fish of the Chambai dam were collected from the different region of Chambai Dam with the help of dam contractor using various types of nets like hand nets, cast nets and hooks from August 2016 to September 2016. In the present study three species were identified Labeo rohita, Hypophthalmichthys molitrix, Catla catla belonging to order Cyprinforms and family Cyprinidae. From the present research it can be concluded that Chambai dam will be best for the fish Cyprinidae family. So, our research will give useful information about the diversity of fishes in Chambai dam that will be later important in taxonomic, fisheries management and conservation.

The study on morphometric and meristic characters of two species of fresh water fishes under order Cypriniformes were carried out in Ichthyology laboratory of Zoological Survey of India, Northern Regional Centre, Dehradun. During the present investigation, 2 families under Cyprinidae and Cobitidae fish species are molacarplet, Amblypharyngodonmola Hamilton (1822) and Lepidocephalichthys guntea (Hamilton, 1822) were identified. The 22 morphometric and 5 meristic counts were studied from Song River, Dehradun. The result showed that all the morphometric characters of two fishes are dependent on the total length. The analyzed data of morphometric dimensions of fish species would be beneficial for the policy makers or planners to develop the scientific strategies for their protection and conservation. The findings will also set the scientific principles for the management and sustainable development of the commercially essential freshwater food fishes.
