Effect of seasonal variation in fish species composition, abundance and diversity of Sunye Lake, Mandalay Region, Myanmar
This study was conducted to assess the species composition , abundance and metrological data influencing fish species diversity based on catch data from landing site of the Sunye Lake. The finding represented that 25 species belonging to 13 families. Cypriniformes was highest composition in community. Both diversity and evenness were low and only a few species were dominated. Low diversity value (H) and highest dominance index values (1-D) were associated with lower diversity estimates for this community. Major dominant species Oreochromis niloticus was the most widely distributed species with a 100% occurrence occurring in the lake. Highest occurrence was recorded during summer. Seasonal abundance of commonly captured species were O. niloticus, Amblypharyngodon atkinsonii, Puntius sophore, Parambassis ranga and Notopterus notopterus . In this community O. niloticus was recorded in the late monsoon and winter whereas A. atkinsonii and P. sophore were recorded in greater abundance during the early monsoon and summer. Finding results indicated that no significant (P<0.05) difference in diversity pattern among the seasons. According to metrological data, we observed similar seasonal pattern trends during two years study. However, productivity was different and their percentage of contribution also differs from each other seasonally. Percent similarity indicated that winter and summer were most similar season in terms of species richness. Seasonal difference in relative abundance indicated that late monsoon and winter were most dissimilarity.
期刊介绍:
Iranian Journal of Ichthyology (IJI) is a peer-reviewed journal for publication of high quality papers on any aspect of ichthyology and will be published 4 times a year by the Iranian Society of Ichthyology (http://www.isi-org.ir). The journal welcomes the submission of manuscripts that meets the general criteria of significance and scientific excellence, and will publish original scientific articles in the fields of ichthyology. The editors welcome the submission of original manuscripts including Research Articles, Short communications, and Views & News. Review papers by distinguished authors and Special Issues will also be considered. It is our aim to provide the international scientific community with an efficiently published journal, meeting high scientific and technical standards. Scopes of Iranian Journal of Ichthyology includes: Systematics, taxonomy, morphology, anatomy, biogeography, biodiversity, conservation, ecology and general biology of fishes (reproduction, food and feeding habits, age and growth, population dynamics, etc.). Papers on freshwater, brackish, marine and fossil fishes will be considered.
