It is distinguished from its congeners except, G. scrobiculus in having a furrow running along the entire length of the ventral surface of the pectoral spine. However, the new species differs from G. scrobiculus in having a posteriorly serrated (vs. smooth) dorsal spine, longer caudal peduncle, shorter head length, shorter adipose-fin base, more abdominal vertebrae (22-23 vs. 19-20) and presence (vs. absence) of numerous tubercles on the pectoral and pelvic-fin rays. Introduction Indian Glyptothorax is poorly understood (Ng, 2005). Eight species of Glyptothorax have been Glyptothorax is the most diverse and the most recorded from the Barak-Meghna-Surma drainage widely distributed sisorid catfish genus, known viz., G. cavia, G. clavatus, G. dikrongensis, G. indi- from the Euphrates River drainage of eastern cus, G. maceriatus, G. manipurensis, G. scrobiculus Turkey eastward to the Yangtze River drainage and G. telchitta.

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.

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.

ARMBRUSTER* Department of Biological Sciences, Auburn University 331 Funchess, Auburn University, Alabama 36849, USA Abstract.—Catfi shes are a broadly distributed order of freshwater fi shes with 3,407 cur- rently valid species. In this paper, I review the different clades of catfi shes, all catfi sh fami- lies, and provide information on some of the more interesting aspects of catfi sh biology that express the great diversity that is present in the order. I also discuss the results of the widely successful All Catfi sh Species Inventory Project. Introduction proximately 10.8% of all fi shes and 5.5% of all ver- tebrates are catfi shes. Renowned herpetologist and ecologist Archie Carr’s But would every one be able to identify the 1941 parody of dichotomous keys, A Subjective Key loricariid catfi sh Pseudancistrus pectegenitor as a to the Fishes of Alachua County, Florida, begins catfi sh (Figure 2A)? It does not have scales, but it with “Any damn fool knows a catfi sh.” Carr is right does have bony plates. It is very fl at, and its mouth but only in part. Catfi shes (the Siluriformes) occur has long jaws but could not be called large. There is on every continent (even fossils are known from a barbel, but you might not recognize it as one as it Antarctica; Figure 1); and the order is extremely is just a small extension of the lip.

  • Native Fish Conservation in Nepal: Challenges and Opportunities
    Nepalese Journal of Biosciences 2: 71-79 (2012) Native fish conservation in Nepal: Challenges and opportunities Tek Bahadur Gurung Nepal Agricultural Research Council, Singh Durbar Plaza, Kathmandu, Nepal E-mail: [email protected] Abstract Habitat degradation and loss probably has been more responsible for the decline of native fish species. Nepalese fishes are one of main aquatic vertebrates which are yet to be studied for their occurrence, distribution and ecology, especially from western regions of the country. However, before complete understanding on native fishes, threat over their existence have been loomed by climate change, over fishing, pollution, alteration of natural habitats and poor understanding of fish ecology etc. Thus, publicizing the importance and knowledge of fish conservation has been one of the most important challenges. The other challenges are sustainability of quality and quantity of freshwaters which have been impacted. In such circumstance to overcome the problems, adoption of community or cooperative based conservation could be one of the best approaches for freshwaters and fish restoration. Optimistically, a national strategy on conservation of freshwater fish is desirable. Fish conservation has the opportunities to be used for multidimensional purposes. A success of single fish species might contribute substantially on local economy, if that could be used in aquaculture or angling for tourism industry. Key words: Anthropogenic activities, native fish, cooperative based conservation Introduction Freshwater fishes are one of the most ignored fauna for conservation, as a result alarming decline in fish diversity persist (Jana, 2007; Shrestha et al. , 2009), especially in urban and southern region of Nepal. The native fish decline is associated with poor knowledge, priority, investment; and water quantity and quality (Shrestha, 2011; Gurung & Baidya, 2012).

  • Diversity of Lips and Associated Structures in Fishes by SEM
    9 Diversity of Lips and Associated Structures in Fishes by SEM Pinky Tripathi and Ajay Kumar Mittal Banaras Hindu University, India 1. Introduction Lips are specialized structures that cover the jawbones, and border the anterior orifice of alimentary canal, the mouth. In general, lips and structures associated with them in different fish species may be considered as mainly concerned with the selection, capture, deglutition and pre digestive preparation of food. The effectiveness of these structures is dependent on modifications in relation to food and feeding habits of the fishes and environmental niches inhabited by them. Morphological data are also key to understanding fish nutrition in ecology and aquaculture, and during development as well as mechanisms for physiological adaptations to a changing environment. A number of the multifunctional roles of the fish lips and associated structures that are discussed incorporate distinctive morphological features that will be highlighted in this chapter. The lips and associated structures represent a significant vertebrate innovation and are highly diversified. Therefore, present work was undertaken to investigate diversity of the epithelia of lips and associated structures in different fresh-water fish species with the aim to elucidate the surface architecture using Scanning Electron Microscope. 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. When we started to survey, collect and organize the current knowledge on lips and associated structures for the invited chapter on SEM, we soon realized that such a study would lead to a greater understanding only if the lips were discussed as incorporate distinctive morphological features.

    Rec. zool. Surv. India: 110(Part-4) : 69-71, 2010 Short Communication FIRST RECORD OF GLARIDOGLANIS ANDERSONII (DAY, 1870) (SILURIFORMES : SISORIDAE) FROM INDIA INTRODUCTION DESCRIPTION While studying the fishes collected from Arunachal D. i.6, P. i.10, V. i.6, A. i.6, C. 16. Pradesh the authors came across a single specimen Body elongated and flattened ventrally, its depth which after a thorough study identified as 6.92 mm. Head and anterior part of the body depressed. Glaridoglanis andersonii (Day, 1870) (Plate-I A, B). Head length 11.37 mm, its width 10.88 mm and depth As per the literature available, distribution of this 5.79 mm. Snout length 10.87 mm. Eyes minute and species was restricted only in the Irrawaddy drainage, dorsally placed, its diameter 1.06 mm with inter-orbital Myanmar and Hotha in Yunan and Ponsee, China (Day, distance 4.03 mm. Mouth transverse and sub-terminal, 1870; Hora and Silas, 1952). Subsequently, Chu et al., thick labial fold, fleshly and papillated, post-labial groove (width 6.29mm and length 2.72mm) broadly (1999) recorded the species from the Brahmaputra interrupted medially. Teeth flattened, strong and blunt. drainage, China (Thomson and Page, 2006). The species Barbels 4 pairs (2 nasal, 2 maxillary and 4 mandibular). is being recorded for the first time from India. Maxillary barbels with well-developed membrane and Thomson and Page (2006) did some revisionary soft base. Gill openings narrow, not extending below work on Asian Sisorids. Norman (1925) erected the pectoral-fin base. Fins are without spines and paired genus Glaridoglanis to accommodate Exostoma fins plaited to form an adhesive apparatus.
