  • Spatio-Temporal Variation of Fish Assemblages in Babai River of Dang District, Province No. 5, Nepal
    Our Nature | December 2019 | 17 (1): 19-30 Spatio-temporal variation of fish assemblages in Babai River of Dang district, Province No. 5, Nepal Punam G.C and Jash Hang Limbu Central Department of Zoology, T.U., Kirtipur, Kathmandu, Nepal E-mail:[email protected] Abstract Spatial and temporal variation of fish assemblages were investigated seasonally from October 2018 to May 2019. Fish assemblages were agglomerated with environmental variables both to spatial and temporal scales. Water temperature, dissolved Oygen, free carbon-dioxide, pH and water velocity of water of each site were measured. Based on analysis of similarities (ANOSIM), fish assemblages were significantly different in spatial variation but not in temporal variation. A total of 1,024 individuals belonging to 5 orders, 9 families and 15 genera and 24 species were collected. The dominated species were Puntius sophore, followed by P. terio, P. ticto and Barilius bendelisis. The Redundancy Analysis (RDA) vindicated that environmental variables of water temperature, pH, water velocity and free carbon-dioxide were found to be contributed variables to shape the fish assemblage structure of Babai River. The cluster analysis delineated that similarity between fish species decreases as the distance of sites increased.

  • Reproductive Biology of Channa Punctata (Bloch, 1793) from Mandalay Environs
    1 Yadanabon University Research Journal, 2019, Vol-10, No.1 Reproductive biology of Channa punctata (Bloch, 1793) from Mandalay Environs Htay Htay Aung, Mie Mie Sein Abstract A total of 383 specimens of Channa punctata were collected from Mandalay environs during the study period from June, 2016 to May, 2017. Sex ratio, length-weight relationship, gonadosomatic index, hepatosomatic index, and fecundity were conducted. The total length of females was ranging from 14.5 cm-21 cm and that of weight, ranging from 32 g-120 g. The total length of males, were ranging from 15.5-22 cm and that of weight, ranging from 38.5 g- 140 g. The sex ratio for male to female was 1: 0.76. Gonadal maturity stages namely, immature, maturing, mature and ripe of maturity in both sexes were recognized during the study period. An inverse relation was observed between GSI and HSI values during the study month. The absolute fecundity of C. punctata ranged from 4667.0 - 9143.46 eggs with the relative fecundity varied from 66.27 - 99.76. Fecundity-ovary weight gave a better relationship in comparison to fecundity-total length and fecundity-body weight relationship. However, as the monthly GSI values in male and female of this species were high during June to August and even to September, the spawning season of C. punctata to fall between June to September. Keywords: Reproductive biology, Channa punctata, Mandalay environs Introduction Channa punctata (Bloch, 1793) belonging to the family Channidae of order Perciformes and has accessory respiratory organs that help the fish to survive in oxygen deficient water bodies.

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.

Three Guwahati, Assam, India types of microbes (bacteria and fungi) were separated from the GI tract of Channa punctata. Pure bacterial cultures were grown on Nutrient Agar (NA) media and were identified as Gram –ve cocci shaped bacteria through morphological test. While pure cultures of fungi were grown on Potato Dextrose Agar (PDA) media and were identified as Penicillium sp. and white sterile mycelia with no spore formation through morphological test. Intestinal isolates were checked for extra-cellular enzyme producing abilities by plate screening method. Amylolytic and cellulolytic microbes were found in the experimental fish’s gut. Cellulase activity was shown by all microbial isolates, while amylase activity was exhibited by the bacterial isolates and Penicillium sp. isolated from the GI tract of Channa punctata. Thus, from the experimented study, it can be concluded that, there would be a possibility of the digestive enzymes to be supplemented by the microbes of the experimental fish’s gut, which would be helpful in the preparation of diets, constituting or including the feeds that are non-conventional ones.

Six iso- proteinous diets were prepared by using different agro industrial by-products. Maximum weight gain was recorded with diet having 66.75% rice bran, 11.50% mustard cake, 23.0% groundnut cake, 5% molasses, 1.5% vitamin-mineral mixture and 0.5% salt with specific growth rate of 0.408. The experimental fish recorded the value of exponent ‘b’ in the range of 2.7675 to 4.3922. The condition factor ‘K’ of all experimental fish was above 1.0 (1.094- 1.235) indicating robustness or well being of experimented fish.

Sagir AHMED*1, Sabrina Rahman DINA1, Luthfun NAHAR1, Nafisa Nawal ISLAM2, Hasan Al REZA3 1Department of Zoology, University of Dhaka, Dhaka 1000, Bangladesh. 2Department of Biotechnology and Genetic Engineering, Jahangirnagar University, Savar, Dhaka 1342, Bangladesh. 3Department of Genetic Engineering and Biotechnology, University of Dhaka, Dhaka 1000, Bangladesh. Corresponding author: *E-mail: [email protected] Abstract The Snakehead fishes have significant economic importance in Bangladesh as food due to their exquisite taste. Some species of snakeheads are considered in threatened categories due to their population decline and loss of habitats. DNA Barcoding has been considered as a global bio- identification system for freshwater and marine fishes in recent years. In the present study, four snakehead species: Channa gachua, C. marulius, C. punctata and C. striata were investigated using both morphological methods and molecular identification with mitochondrial Cytochrome c Oxidase subunit I (COI) gene. Our study confirms that no C. orientalis existing in Bangladesh and all the older reports are pertaining to C. gachua. Phylogenetic relationships, the divergence of sequences between species was determined using Kimura 2-parameter distance model, and a Maximum Likelihood tree was generated in which the COI sequences for each of the four species could clearly be discriminated. The average interspecies genetic divergence was 26.90%. The study strongly validated the efficacy of COI as an ideal marker for DNA barcoding of Bangladeshi freshwater fishes and identification of specific species that necessitate further taxonomic study.

J.V Navya Latha & Ramesh K. & Prof.V.Vanithadas Dept. of Zoology, University College of Science, Osmania University, Hyderabad. Received: January 13, 2019 Accepted: February 24, 2019 ABSTRACT: The aim of this study to biochemically investigate the conventional pathway of carbohydrate metabolism occurs in both in aerobic and anaerobic conditions. In aerobic process glycogen is broken into release energy through a series of reactions. Aerobic segments includes oxidation of pyruvate to acetyl CoA which is utilized in another cycle called citric acid cycle. Such utilization of reduced coenzymes results in ATP synthesis through oxidative phosphorylation (Martin et al., 1983).Fish like any other organism utilizes the carbohydrates to meet their energy requirements. The conversion of glycogen to glucose and the related release of energy could be affected by the infections. The gastro-intestinal tract and liver are the most common tissue affected by the parasites. Such intestinal infections might interfere with the absorption of food and might cause disorders of metabolism, liver is the seat of major metabolic activities,and any sort of infection in liver could alter the carbohydrate metabolism and reach the other organs. In anaerobic Glycolysis, through a series of enzymatic reactions, sugars are converted to lactic acid and ATP. Pyruvate which is the end product of glycolysis is converted to acetyl CoA which is oxidized in TCA cycle to release energy in aerobic conditions.
