Project No.: 7879140169 Report Issue Form ESIA REPORT, YAOURE GOLD PROJECT APPENDIX 18 CRITICAL HABITAT ASSESSMENT JUNE 2015 E X E C U T I V E S UMMARY This Critical Habitat Assessment aimed at evaluating Critical Habitat qualifying features present in the Project area in order to determine if they trigger Critical Habitat according to IFC PS6. Critical Habitat is defined as an area harbouring high biodiversity value (IFC, 2012). This area needs to meet at least one or more of the five main criteria provided in Paragraph 16 of the IFC PS6: Habitat of significance for globally or nationally critically endangered or endangered species; Habitat of significance for endemic and/or restricted range species; Habitat of significance for migratory and/or congregatory species; Highly threatened and/or unique ecosystems; and Areas associated with key evolutionary processes. As the area where the Project will be developed has been highly degraded over the years, the habitat is considered ‘modified’ with no natural habitat remaining according to the definition given by the IFC. The unit of analysis used in this CHA was a discrete management unit (DMU), which amounted to a surface of 3,150 km2. A total of 14 species that could trigger critical habitat were recorded during biodiversity baseline surveys conducted between November 2014 and May 2015. The extent of occurrence of these species within the DMU was then compared to their global distribution range using thresholds provided by the IFC Performance Standards 6. The Critical Habitat Assessment revealed four species present in the Project area that triggered Critical Habitat, two fish species, one amphibian, and one plant species. Quantification of Critical Habitat extent and residual losses relating to the proposed mining activities need to be undertaken, and the Project needs to demonstrate a Net Positive Impact in Critical Habitat. Further recommendations are included in the BMP. The baseline biodiversity surveys conducted for the ESIA also allowed to extend the distribution range (according to their EOO on the IUCN Red List) of five species: two fish (Tilapia walteri NT and Tilapia busumana VU), one reptile (Hemidactylus fasciatus), one plant (Strychnos millepunctata VU) and one bird species (Bathmocercus cerviniventris NT).

  • La Biodiversité En Côte D'ivoire : Etat Des Lieux Et Facteurs De Menace
    La biodiversité en Côte d’Ivoire : Etat des lieux et facteurs de menace 5 Biodiversity of Côte d’Ivoire: Current state and threats L’une des caractéristiques les plus fascinantes de la nature est la diversité des êtres vivants dont elle regorge. La biodiversité est définit simplement comme la diversité de toutes les formes du vivant, incluant la diversité génétique, spécifique et écosystémique. Elle constitue la toile de la vie terrestre et aquatique dont nous sommes partie intégrante et dont nous dépendons totalement pour notre bien être et notre survie. Elle atteint son maximum dans les régions tropicales dont les forêts abritent plus de 50 % de la diversité biologique mondiale. En Côte d’Ivoire, la conservation de la biodiversité est une question majeure au regard de son importance et des menaces fréquentes qui pèsent sur elle. En effet, de par la diversité et la particularité de sa flore et de sa faune, la Côte d’Ivoire fait partie des zones prioritaires de conservationhot ( spot de biodiversité) en Afrique de l’Ouest. Cependant cette diversité biologique est fortement menacée par de nombreux facteurs dont les plus importants sont la déforestation, l’agriculture non durable, le braconnage, la pollution et les changements climatiques. Ces menaces qui affectent considérablement aussi bien les écosystè- mes que les organismes vivants qu’ils abritent, ont un effet déterminant sur l’économie et la qualité de la vie humaine. Ce chapitre a pour objectif de faire un état des lieux de la biodiversité en Côte d’Ivoire et d’identifier les facteurs pouvant menacer sa conservation. Il comprend trois parties qui s’articulent autour des composantes essentielles de la biodiversité.

This was carried out so as to evaluate its quantity (biomass) caught by fishing and also its morphological characteristics. The fish were caught using gillnets at 4 sites of the lake and different measurements were made. The fishing effort was 23 to 11 fishermen / day in Taabo city, 17 to 11 fishermen / day in Courandjourou, 13 to 5 fishermen / day in Ahondo, and 8 to 3 fishermen / day in Taabo village. The catch per unit effort (CPUE) ranged from 17.7 to 3.7 g / fisherman / day, 9.2 to 1.2 g / fisherman / day, 8.3 to 0.7 g / fisherman /day, 8 to 1g / fisherman / day at Ahondo, Courandjourou, Taabo city and Taabo village, respectively.

Received 29 November, 2018; Accepted 6 February, 2019 This study aims to characterize the spatio-temporal variation of the fish assemblages in relation to the environmental variables of Buyo Dam Lake. Sampling was performed from July 2017 to June 2018 using experimental fishing and commercial fishing. Spatio-temporal analysis indicated a significant variation (p <0.05) in pH, electrical conductivity, total dissolved solids, and water transparency. A total of 45 species from 27 genus and 15 families were collected in the samples sites. Two species (Chrysichthys johnelsis and Malapterurus barbatus) are reported for the first time in the lake of Buyo. Among the fishes sampled, of Cichlidae (35.04%) and Claroteidae (16.43%) were the most abundants. The abundant species are Oreochromis niloticus (15.55%) and Chrysichthys nigrodigitatus (15.15%). The analysis of the structure of fish assemblages (H' from 2.28 to 2.75, E from 0.68 to 0.84) revealed a fairly diverse lake environment.

  • 11 Diet of Synodontis Victoriae (Mochokidae) from Kunya Beach
    International Journal of Fisheries and Aquatic Research International Journal of Fisheries and Aquatic Research ISSN: 2456-7248 www.fishjournals.com Volume 1; Issue 1; November 2016; Page No. 11-15 Diet of synodontis victoriae (mochokidae) from Kunya beach lake Victoria, Kenya Wanyanga Aquiline, Yongo Edwine, Mwangudza Petronilla University of Eldoret, Department of Fisheries and Aquatic Sciences, Eldoret, Kenya Abstract Studies on the diet of Synodontis victoriae were conducted from Kunya beach Lake Victoria, Kenya. Sampling was done four times: twice during rainy period (December, 2015) and twice during dry spell (January, 2016). The fish were caught using beach seine of mesh size 1.5-3.0 inches, length 350m and width 3m. Each specimen was measured in centimeter Fork length (FL, cm) and sex determined. The guts were then removed and preserved in 4% formalin prior to laboratory analysis. A total of 173 stomachs were examined, and the diet constituted of 9 food items out of which plant detritus, chironomids and copepods formed the major components. Spearman test revealed significant similarities in diet with respect to sex, season and size classes (p<0.05). However, the fish fed more on plant detritus (index of preponderance: Ip = 24.0%)) during the dry season and more on chironomids (Ip = 24.0%) in the rainy season. In terms of size, smaller fish 8.0-9.9 cm FL fed more on zooplankton copepods (Ip = 22.4.0%), while plant detritus (Ip = 32.0%) dominated the diet of adults in the length group 14.0-15.9 cm FL. Synodontis victoriae was considered to be omnivorous from the nature of the food items eaten.
