The analysis of its gut content revealed the presence of 62 genera of planktonic life forms along with other animal matters. The organization of the alimentary tract and maximum Relative Mean Length of Gut (0.511±0.029 mm) indicated its carnivorous food habit. The peak gastro-somatic index (GSI) in winter-spring seasons and summer-rainy seasons indicated alteration of its feeding intensity. Furthermore, higher diet breadth on resource use (Levins’ and Hurlbert’s) with zooplankton compared to phytoplankton and Keywords: total plankton confirmed its zooplanktivore habit. The feeding strategy Diet breadth plots also suggested greater preference to zooplankton compared to Feeding strategy phytoplankton. The organization of its gill rakers specified a secondary Pachypterus atherinoides modification of gut towards either carnivory or specialized zooplanktivory. -
Physicochemical Assessment and Water Quality of Surface Water in Chandel and Tengnoupal Districts, Manipur for Domestic and Irrigational Uses
International Research Journal of Engineering and Technology (IRJET) e-ISSN: 2395-0056 Volume: 08 Issue: 01 | Jan 2021 www.irjet.net p-ISSN: 2395-0072 Physicochemical Assessment and Water Quality of Surface Water in Chandel and Tengnoupal Districts, Manipur for Domestic and Irrigational Uses Herojit Nongmaithem*1, Maibam Pradipkanta Singh2 & Sujata Sougrakpam3 1-3Geological Survey of India, SU: MN, Imphal office, Imphal, 795004 ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract: The study aims to validate the water quality for domestic and irrigational uses based on the physico chemical properties of the surface waters in parts of Chandel and Tengnoupal districts of Manipur. The sources of the dissolved constituents in the samples suggest Mg-Ca-HCO3-Cl as the dominant hydro-facies and are magnesium bicarbonate water types. The dominant geochemical process that governs the water chemistry is rock weathering dominance. WQI of the water samples ranges from 76.18 to 155.33 and is well within the limits of the BIS and WHO guidelines for drinking water. All the samples are suitable for irrigational uses based on the determined values of EC, TDS, SSP and SAR. Hence, these perennial rivers and streams hold the potential to provide uninterrupted supply of drinking and irrigational water to Chandel, Tengnoupal, Kakching and Thoubal districts of Manipur without any major treatment. Keywords: Physico-chemical, hydrochemical facies, Water Quality, Manipur 1. Introduction Urbanisation catalyst the human dependency on the water consumption either for domestic or irrigational uses. Rivers and streams show spatial heterogeneity in the physico-chemical indices which enable to categorize the water for different uses or to detect toxicity. -

A Diminutive New Species of Glyptothorax (Siluriformes
375 Ichthyol. Explor. Freshwaters, Vol. 16, No. 4, pp. 375-383, 4 fi gs., December 2005 © 2005 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 A diminutive new species of Glyptothorax (Siluriformes: Sisoridae) from the upper Irrawaddy River basin, Myanmar, with comments on sisorid and erethistid phylogenetic relationships Carl J. Ferraris, Jr.* and Ralf Britz** Glyptothorax panda, new species of the Asian catfi sh family Sisoridae, is described based on specimens from the upper Irrawaddy River basin, near Myitkyina, Myanmar. The species appears to be the smallest species of the genus Glyptothorax, and matures at 32 mm standard length or less. The species is distinguishable from congeners by a combination of meristic and color pattern characters. Several characters observed in this species resemble characters which have been hypothesized as derived states for some, or all, species of the family Erethistidae, which calls into question the validity of the current distinction between the Erethistidae and the Sisoridae. The new species exhibits a color pattern similar to that found in the syntopic species Akysis prashadi, which suggests the possibility of a mimetic relationship between the two species. Introduction nese species (Chu & Mo, 1999) cover a large percentage of the taxa. The sisorid catfi sh genus Glyptothorax is the most Until now, only fi ve species had been re- widely distributed genus of the family, extending ported from Myanmar, although this is in all longitudinally from Turkey to Fujian (China), and likelihood a substantial underestimate due, in from the south-draining Himalayan river basins part, to incomplete sampling of fi shes of that south to Java. -

Ichthyofaunal Diversity and Conservation Status in Rivers of Khyber Pakhtunkhwa, Pakistan
Proceedings of the International Academy of Ecology and Environmental Sciences, 2020, 10(4): 131-143 Article Ichthyofaunal diversity and conservation status in rivers of Khyber Pakhtunkhwa, Pakistan Mukhtiar Ahmad1, Abbas Hussain Shah2, Zahid Maqbool1, Awais Khalid3, Khalid Rasheed Khan2, 2 Muhammad Farooq 1Department of Zoology, Govt. Post Graduate College, Mansehra, Pakistan 2Department of Botany, Govt. Post Graduate College, Mansehra, Pakistan 3Department of Zoology, Govt. Degree College, Oghi, Pakistan E-mail: [email protected] Received 12 August 2020; Accepted 20 September 2020; Published 1 December 2020 Abstract Ichthyofaunal composition is the most important and essential biotic component of an aquatic ecosystem. There is worldwide distribution of fresh water fishes. Pakistan is blessed with a diversity of fishes owing to streams, rivers, dams and ocean. In freshwater bodies of the country about 193 fish species were recorded. There are about 30 species of fish which are commercially exploited for good source of proteins and vitamins. The fish marketing has great socio economic value in the country. Unfortunately, fish fauna is declining at alarming rate due to water pollution, over fishing, pesticide use and other anthropogenic activities. Therefore, about 20 percent of fish population is threatened as endangered or extinct. All Mashers are ‘endangered’, notably Tor putitora, which is also included in the Red List Category of International Union for Conservation of Nature (IUCN) as Endangered. Mashers (Tor species) are distributed in Southeast Asian and Himalayan regions including trans-Himalayan countries like Pakistan and India. The heavy flood of July, 2010 resulted in the minimizing of Tor putitora species Khyber Pakhtunkhwa and the fish is now found extinct from river Swat. -

The three data sets were analyzed separately and combined into a single data set to reconstruct phylogenetic relationships among Chinese sisorids. Both Chinese Sisoridae as a whole and the glyptosternoid taxa formed monophyletic groups. The genus Pseudecheneis is likely to be the earliest diverging extant ge- nus among the Chinese Sisoridae. The four Pareuchiloglanis species included in the study formed a monophyletic group. Glaridoglanis was indicated to be earliest diverging glyptosternoid, followed by Glyptosternon maculatum and Exostoma labi- atum. Our data supported the conclusion that Oreoglanis and Pseudexostoma both formed a monophyletic group. On the basis of the fossil record and the results of a molecular dating analysis, we estimated that the Sisoridae diverged in the late Miocene about 12.2 Mya. The glyptosternoid clade was indicated to have diverged, also in the late Miocene, about 10.7 Mya, and the more specialized glyptosternoid genera, such as Pareuchiloglanis, originated in the Pleistocene (within 1.9 Mya). The specia- tion of glyptosternoid fishes is hypothesized to be closely related with the uplift of the Qinghai-Tibet Plateau. -

Taxonomic Glyptoth orax Glyptosternum PseudeclIeneis The following notes are based on the named and un named collection of the genera Gtyptothorax, GlyptnsternUl1t and Pseude che1~eis in the Indian Museum. A valuable series of specinlens was recently added to our collection froln the Kashtnir Valley and I have been able to elucidate several facts copcerning these genera from fishes collected by nlyself in the Khasi Hill'). To Dr. N . ..-\nnandale and to Dr. S. W Kemp I am greatly indebted for going throngh the manuscript and proofs with nle and for making numerous valua hIe suggestions. INTRODUCTION In 1842 McClelland J proposed the genus Glyptosternon and included five new species in it .. viz. G. reticulatus, G. sftleatlls, G. striatus, G. peetinopterus and G. labiatus. The genus \vas very insufficiently characterized and Blyth 2 in 1860 recognized in it as many as four distinct generic types. He retained l\1cCle lland' s desigllation Glyptosternon for the first species, G. reticula/us, from Afghanistan. l'he second species (G. sulcat1.ts) was lllade the type of a new genus, Pseudecheneis; the next two, along \vi th a llew species from Tenasserim, were included under the generic denotni nation Glyptothorax. The last species, G. labiatus from the " Mishmee Mountains" was referred to the genus Exostol1ta, which he distinguished by " the form of the mouth" and " the remark ably small gill-openings." He described a species, ExostollJa berd1'ltorei, from 'renasserim as the type ot' his last genus. -
