From India: a Glimpse Through Advanced Morphometric Toolkits
Morphological plasticity in a wild freshwater sh, Systomus sarana (Cyprinidae) from India: a glimpse through advanced morphometric toolkits Deepmala Gupta University of Lucknow Faculty of Science Arvind Kumar Dwivedi Barkatullah Vishwavidyalaya Faculty of Life Sciences Madhu Tripathi ( [email protected] ) University of Lucknow Faculty of Science https://orcid.org/0000-0003-1618-4994 Research article Keywords: Intraspecies diversity, Morphological variations, Systomus sarana, Landmark based analysis Posted Date: November 5th, 2020 DOI: https://doi.org/10.21203/rs.3.rs-35594/v2 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/32 Abstract Background: Body morphology supposed to underpin wide differences in animal performance that can be used to understand the diversication of characters. Further, identifying the sh population with unique shape due to variations in their morphometric characters enable better management of these subunits. Advanced statistical toolkits of morphometry called truss network system and geometric morphometrics have been increasingly used for detecting variations in morphological traits between subunits of sh populations. The present study was therefore carried out with the objective of determining phenotypically distinct units of freshwater sh Systomus sarana collected from geographically isolated locations. Methods: In the present study, 154 specimens of olive barb, S. sarana were collected from four distantly located rivers covering the northern (Ganga), southern (Godavari), central (Narmada), and eastern (Mahanadi) regions of India. Truss-network system and geometric morphometrics have been utilized. Fourteen landmarks were digitized uniformly on each specimen. In the present study, the truss network system yielded size-corrected morphometric characters that were subjected to univariate and multivariate statistical assessment. -

Introduction Geological Investigations for Moragahakanda dam were commenced by USOM in 1959, and core drilling surveys were subsequently done by UNDP/FAO and Irrigation Department of Sri Lanka in 1967/1968 and 1977/1978 respectively. A full-scale geological investigation including core drilling, seismic prospecting, work adit, in-situ rock shear test, construction material survey and test grouting was carried out for the feasibility study by JICA in 1979 (hereinafter referred to FS (1979)). Almost twenty years had past after FS (1979), additional feasibility study including 34 drill holes was carried out by Lahmeyer International Associates in 2000/2001 (hereinafter referred to FS (2001)). Subsequently, supplemental geological investigations including core drilling, electric resistivity survey and laboratory tests for rock materials were done by MASL in 2007. -
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. -

Extreme hydro -climatic events and its consequent shifts in seasonality lead to water scarcity in dry zone aquatic resources such as Vavuniya reservoir, threatening fish species richness and abundance. Weekly filed surveys were made to collect biological, ecological and hydro -climatic data from January, 2013 to July, 2014. Fish species composition a nd abundance in the catch were estimated by using random sampling at the landing site. Clarias brachysoma, Esomus thermoicos and Labeo lankae were the endemic freshwater fish species identified along with 16 indigenous and 8 exotic species. A significantly higher abundance of indigenous species was found in July and August 2013. During these periods, higher rainfall was observed but water level receded to medium level. Peak abundance of Channa striata (July & August 2013 and March & July 2 014), Puntius dorsalis (August 2013 and July 2014) and P. -
Proceedings of a Workshop on the Development of a Genetic Improvement Program for African Catfish Clarias Gariepinus
Proceedings of a Workshop on the Development of a Genetic Improvement Program for African Catfish African catfish (Clarias gariepinus) production has gained considerable importance in a number of African countries. The species has several desirable attributes that make it attractive for aquaculture development. It is easy to reproduce, it does not require specialized feed, it tolerates high stocking densities, it accepts artificial feed, it tolerates poor water quality, and very importantly, it is highly sought after in local markets and economically viable in pond production systems. The species is endemic to Africa. In 2007 the WorldFish Center organized a workshop in Accra, Ghana, hosted by the Water Research Institute, to review the status of the catfish industry in Africa and develop recommendations on how best to approach the issue of genetic improvement programs. The results of the workshop are presented in this volume.

A Case Study of the Kotmale Dam in Sri Lanka Jagath Manatungea* and Naruhiko Takesadab

In this paper the resettlement scheme of the Kotmale Dam in Sri Lanka is revisited, focusing on resettlers’ positive perceptions. Displaced communities expressed satisfaction when income levels and stability were higher in addition to their having access to land ownership titles, good irrigation infrastructure, water, and more opportunities for their children. However, harsh climate conditions, increased incidence of diseases and human–wildlife conflicts caused much discomfort among resettlers. Diversification away from paddy farming to other agricultural activities and providing legal land titles would have allowed them to gain more from resettlement compensation. Keywords: dam construction; involuntary displacement; livelihood rebuilding; resettlement compensation Introduction Over the decades, there has been growing concern about the negative consequences of the involuntary displacement of rural communities for large-scale infrastructure development (De Wet, 2006; Robinson, 2003). The construction of dams is the most often cited example of development projects that cause forced displacement of communities (McCully, 2001). -
