  • Freshwater Fish Survey of Homadola-Nakiyadeniya Estates, Sri Lanka
    FRESHWATER FISH SURVEY OF HOMADOLA-NAKIYADENIYA ESTATES, SRI LANKA. Prepared by Hiranya Sudasinghe BSc. (Hons) Zoology, M.Phil. reading (University of Peradeniya) INTRODUCTION The diversity of freshwater fishes in Sri Lanka is remarkably high, with a total of 93 indigenous fishes being recorded from inland waters, out of which 53 are considered to be endemic (MOE, 2012; Batuwita et al., 2013). Out of these, 21 are listed as Critically Endangered, 19 as Endangered and five as Vulnerable in the National Red List (MOE, 2012). In addition, several new species of freshwater fishes have been discovered in the recent past which have not yet been evaluated for Red Listing (Batuwita et al., 2017; Sudasinghe 2017; Sudasinghe & Meegaskumbura, 2016; Sudasinghe et al., 2016). Out of the 22 families that represent the Sri Lankan freshwater ichthyofauna, the family Cyprinidae dominates, representing about 50% of the species, followed by the families Gobiidae, Channidae and Bagridae, which represent seven, five and four species, respectively. The remainder of the other families are each represented in Sri Lanka by three species or less. Four major ichthyological zones, viz. Southwestern zone, Mahaweli zone, Dry zone and the Transition zone were identified by Senanayake and Moyle (1982) based on the distribution and the endemism of the fish. The Southwestern zone shows the greatest diversity, followed by the Mahaweli zone, with the least diversity observed in the Dry zone. About 60% of the freshwater fishes occur both in the dry and the wet zones of the island while the rest are more or less restricted to the wet zone. Of the endemic fishes, more than 60% are restricted to the wet zone of the island while about 30% occur in both the dry and the wet zones.

The present study was undertaken in order to untangle some of the problems of classification which have beset this group. The genera have not been studied in toto since the days of Bleeker and Gunther. In this study I have made an attempt to clarify the relationships of the various genera, which in some cases has involved revision of generic limits. Lack of time and material has precluded a thorough analysis of the species within any genus; for the same reason no skeletal examinations were possible. It is hoped, however, that a clarification of generic limits through study of external characters will make it easier in the future for interested workers, with sufficient material at hand, to do further and much-needed work on both the genera and the species.

The experiment was conducted in the breeding seasons from December, 2007 to November, 2010. Artificial breeding of Ompok pabo (Hamilton-Buchanan) were carried out at Goalpara College (Latitude 26 0 10 / 11 // N and Longitude 90 0 37 / 37 // E), Goalpara, Assam; India. Fertilized eggs were examined using a microscope till the end of larval developmental period to record each and every stage of embryonic and larval development. Key words: embryonic development, Ompok pabo , breeding, larvae. _____________________________________________________________________________________________ INTRODUCTION Embryonic development is a complex process in which cellular differentiation and proliferation occur simultaneously but at different rate [1]. Changes in the pattern of the entire structure of an organ or of specific organ in relation to the environment are decisive for evaluating the developmental pattern of a species [2]. Ompok pabo commonly known as ‘ pabo ’ is an Indian freshwater catfish with good market demands particularly in North-Eastern part of India. It is also a delicious, tasty, nutritious catfish having relatively few bones. However, over the last few decades, its wild population has undergone a steady decline mainly due to over exploitation, loss of habitat, disease, pollution, siltation, poisoning, dynamite and other destructive fishing [3].

It originates from the central hills and flows through a diverse array of landscapes, including some of the most urbanized regions and intensive land uses. Kelani River suffers a multitude of environmental issues: illegal water diversions and extractions, impoundment for hydroelectricity generation, and pollution, mostly from agrochemicals, urban runoff, industrial discharges, and domestic waste. Moreover, loss of riparian forest cover, sand-mining, and unplanned development in floodplains have accentuated the environmental damage. In this study, based on Kelani River basin, we reviewed the status of biodiversity, threats encountered, conservation challenges, and provided guidance for science-based conservation planning. Kelani River basin is high in biodiversity and endemism, which includes 60 freshwater fish species of which 30 are endemic.

    Iranian Journal of Fisheries Sciences 17(3) 458-470 2018 DOI: 10.22092/IJFS.2018.116612 Gonadal maturity assessment of butter catfish (Ompok bimaculatus) from major rivers and tributaries of India during spawning season Mishra A.1*; Sarkar U.K.2; Kumar R.3; Rawat A.4; Verma S.5 Received: September 2015 Accepted: January 2017 Abstract The present work focused on exploring reproductive biology of fish from different major rivers of India and their tributaries by comparing ovarian protein, fecundity, oocyte weight, oocyte diameter and condition factor during the spawning period. Significant correlation was found between reproductive parameters of fish in the major rivers and their tributaries. Among the parameters studied fecundity showed the highest correlation with ovarian protein level and oocyte weight in the major rivers, whereas in tributaries it was highly correlated with ovarian protein. The results from a wild population showed that the fecundity and ovarian protein level were significantly higher in the Narmada River, and the lowest in river Ganga (U.P.). Among the tributaries, maximum ovarian fecundity was observed in fish with the highest protein concentration from River Hooghly. The condition factor (K) in female Ompok Downloaded from jifro.ir at 14:24 +0330 on Monday October 4th 2021 bimaculatus were reported to be significantly high in the major River Cauveri and Sharda tributary. The oocyte weight was significantly higher in the major River Krishna and the lowest in fish from River Godavari. In fish samples collected from tributaries, those Sone River showed the highest oocyte diameter and fish from Betwa River showed the lowest oocyte diameter.

  • Diverse Activities and Biochemical Properties of Amylase and Proteases from Six Freshwater Fsh Species Chamaiporn Champasri*, Suthathip Phetlum & Chanakan Pornchoo
    www.nature.com/scientificreports OPEN Diverse activities and biochemical properties of amylase and proteases from six freshwater fsh species Chamaiporn Champasri*, Suthathip Phetlum & Chanakan Pornchoo This study investigated the biochemical properties, enzyme activities, isoenzyme pattern, and molecular weight of three types of digestive enzyme from six freshwater fsh species: Puntius gonionotus (common silver barb), Puntioplites proctozysron (Smith’s barb), Oreochromis niloticus (Nile tilapia), Hemibagrus spilopterus (yellow mystus), Ompok bimaculatus (butter catfsh), and Kryptopterus geminus (sheatfsh). The optimum pHs for amylase and alkaline protease activities were 7.0–8.0 and 8.0–10.0, and the optimum temperatures were 45–60 °C and 50–55 °C, respectively. A pepsin-like enzyme was detected in all three carnivorous fshes (Ompok bimaculatus, Kryptopterus geminus, and Hemibagrus spilopterus) with optimum reaction pH of 2.0 for each and optimum reaction temperatures 50–55 °C. In optimum reaction conditions, the amylase and alkaline protease from Puntioplites proctozyron showed the highest activities. Lower activities of all enzymes were observed at temperature (29 °C) of Lam Nam Choen swamp than at the optimum reaction temperatures. The fsh species contained one to three and fve to eight isoforms of amylase and alkaline protease, respectively, with molecular weights from 19.5 to 175 kDa. Both the alkaline proteases and amylases were stable in wide pH and temperature ranges. Amylase and protease are important enzymes in cellular metabolism in plants, animals, and microorganisms. Both enzymes function to catalyze degradation of macromolecules into small building blocks, which are subse- quently used to produce energy or to synthesize other biomolecules inside cells.

The growth performance and water quality parameters (temperature, DO, pH, TAN and NO2-N) in culture were investigated. Water quality seemed not to be controlled by temperature but by feed consumption. DO concentration decreased (8.27+0.10 mg/l) in the 33 °C tank (P<0.05). Growth of catfish performed well in all treatments except fish in the 33 °C tank, in which the percentage weight and length gain declined (479.70+86.64% and 73.85+10.52%, respectively) (P<0.05), and both SGR and feed intake significantly decreased (2.55+0.26 %/day and 194.28+42.40 g, respectively) (P<0.01). FCR and survival were positive in every temperature exposure (P>0.05). Results reveal that the maximum thermal tolerance for growth is best in water temperature which does not exceed 31 °C. Keywords: butter catfish, water quality, growth performance, water temperature 1.

    CATFISH Hearing the name catfish probably makes most readers think of the walking catfish (Clarias batrachus) so common in the markets along the Mekong river, or the Giant Catfish (Pangasianodon gigas), one of the biggest freshwater fishes in the world. But the group of catfishes (the order Siluriformes) actually includes at least 31 families and some 2200 species. The majority of these species, however, are endemic to South America. The approximately 125 catfish species, so far recorded in the Mekong basin, belong to 11 families: Bagrid catfishes (Bagridae), sheatfishes (Siluridae), schilbeid catfishes (Schilbeidae), river catfishes (Pangasiidae), sisorid catfishes (Sisoridae), torrent catfishes (Amblycipitidae), beaded catfishes (Akysidae), airbreathing catfishes (Clariidae), airsac catfishes (Heteropneustidae), sea catfishes (Ariidae), and eel-tail catfishes (Plotosidae). As might be expected from such a large group, there is considerable variation in size and shape. Adult beaded catfish species, for example, will only be a couple of centimeters long, while the giant catfish can reach 300 cm. The elongated body without scales, the flattened head with small eyes and barbels (whiskers), and usually the presence of stout spines in dorsal and pectoral fins, sometimes together with protective covering of bony plates, normally makes it easy to recognize a catfish when you see it. The taxonomic relationship between catfishes and carps is evident from the many characters shared by the two groups eg. the Weberian apparatus, fear scent and presence of barbels (see Catch and Culture sup. 1). Barbels in catfishes however, are more conspicuous and more numerous (1-4 pairs). Other differences are that the jaws in catfishes have teeth, while carps are toothless.
