Oreoglanis Pangenensis, a New Species of Torrent Catfish from Arunachal Pradesh, India (Siluriformes: Sisoridae)
331 Ichthyol. Explor. Freshwaters, Vol. 25, No. 4, pp. 331-338, 6 figs., 1 tab., March 2015 © 2015 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 Oreoglanis pangenensis, a new species of torrent catfish from Arunachal Pradesh, India (Siluriformes: Sisoridae) Bikramjit Sinha*, ** and Lakpa Tamang* Oreoglanis pangenensis, new species, is described from the Pange River, upper Brahmaputra River basin, Apatani plateau, Lower Subansiri District, Arunachal Pradesh, India. It belongs to the O. siamensis species group and is distinguished from all its congeners by a combination of two types of projections on the ventroposterior margin of the maxillary barbel: the proximal one-third with lobulate projections and the distal two-thirds with laciniate projec- tions. It is further distinguished from members of the O. delacouri group in having a median notch on the posterior margin of the lower lip, an entire lower lip margin, and (except for O. tenuicauda) an emarginate caudal fin.

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. -
Aliens; a Catastrophe for Native Fresh Water Fish Diversity in Pakistan
The Journal of Animal and Plant Sciences, 21(2 Suppl.): 2011, Page: 435-440 ISSN: 1018-7081 ALIENS; A CATASTROPHE FOR NATIVE FRESH WATER FISH DIVERSITY IN PAKISTAN A. M. Khan, Z. Ali, S. Y. Shelly* Z. Ahmad** and M. R. Mirza** Department of Zoology, University of the Punjab, Lahore *Department of Fisheries, Government of Punjab, Munawan, Lahore. Department of Zoology, Government College University, Lahore Corresponding author e-mail: [email protected] ABSTRACT Pakistan has introduced several alien exotic fish species e.g. grass carp (Ctenopharyngodon idella), bighead carp, (Hypophthalmichthys nobilis), silver carp, (Hypophthalmichthys molitrix), common carp (Cyprinus carpio), gold fish (Carassius auratus), and three species of tilapia (Oreochromis aureus, Oreochromis mossambicus, Oreochromis niloticus) in warm waters along with two trout species: the rainbow trout (Onchorynchus mykiss) and the brown trout (Salmo trutta fario) in colder regions for specific purposes like sport fishing, yield enhancement and biological control of aquatic weeds and mosquitoes. The exotic species are becoming invasive in the freshwater biomes of the Punjab and other provinces of Pakistan by reason of their potent reproductive potential and feeding competitions with the native freshwater fish fauna. Resultantly the native fish species viz; Channa marulius, Wallago attu, Rita rita, Sperata sarwari, Gibelion catla, Cirrhinus mrigala and Labeo rohita, which are of economic value are under threat.

Department of Zoology, Surajmal Agarwal Girls, P.G. College Kichha, K.U. Nainital, 263145. Abstract: The lips and associated structures, in different groups of fishes, are greatly modified in relation to the characteristic mode of feeding, food preference and the mode of life exhibited by the fish. The successful maintenance of fish populations in challenging environments requires responsive adjustments in their behaviour, morphology and physiology and these have been reflected by modifications at the level of their organ systems, organs and tissues. The lips are no exception to this. The importance of food in daily life of a fish is obvious and is reflected in the form of the mouth, lips, jaw and so on. These structures present more diverse modifications than any other organ of the body. The functional aspects of the lips and associated structures in family Gobiidae, Cobitidae, Belontiidae and few species of Cyprinidae show considerable variation and exhibit unique morphological modifications associated with their lips and other structures around the mouth regarding information on the level of surface architecture as seen under SEM in relation to various food and feeding habits and ecological niches. Key words: Cyprinidae, fishes, lip and morphology. -

Ascidians from the Tropical Western Pacific
Ascidians from the tropical western Pacific Françoise MONNIOT Claude MONNIOT CNRS UPESA 8044, Laboratoire de Biologie des Invertébrés marins et Malacologie, Muséum national d’Histoire naturelle, 55 rue Buffon, F-75005 Paris (France) [email protected] Monniot F. & Monniot C. 2001. — Ascidians from the tropical western Pacific. Zoosystema 23 (2) : 201-383. ABSTRACT A large collection of 187 identified ascidian species is added to the records published in 1996 from the same tropical western Pacific islands. Most of the specimens were collected by the US Coral Reef Research Foundation (CRRF). They come from depths accessible by SCUBA diving. Most of the collection’s species are described and figured, their color in life is illustrated by 112 underwater photographs; among them 48 are new species represent- ing a fourth of the material collected. This demonstrates how incomplete the knowledge of the ascidian diversity in this part of the world remains. Moreover, very small or inconspicuous species were seldom collected, as com- pared to the highly coloured and large forms. Many other immature speci- mens were also collected but their precise identification was not possible. Almost all littoral families are represented with the exception of the Molgulidae which are more characteristic of soft sediments, a biotope which was not investigated. Among the very diversified genera, the colonial forms largely dominate, including not only all the Aplousobranchia genera but also some Phlebobranchia and Stolidobranchia. Very often only one specimen was KEY WORDS Tunicata, available, so a detailed biogeographical distribution cannot be given, and no western Pacific Ocean. island endemism can be defined.

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. -

Page Introduction 1 Biological .J. 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.
