Turkish Journal of Zoology
One hundred and eighty juveniles of Oreochromis niloticus with a respective smean total length and weight of 7.30 ± 0.5 cm and 7.05 ± 0.5 g and 180 fry of Clarias gariepinus with a mean total length and weight of 14.90 ± 0.1 cm and 32.10 ± 0.5 g were separately cultured in 3 replicates in 18 plastic tanks (1 × 1 × 0.5 m; 200 L), 9 for O. niloticus and 9 for C. gariepinus, for photoperiods of 24 L: 0 D, 0 L: 24 D, and 12 L: 12 D for 13 weeks. Mortality and welfare impairment were …

The Use Of Bmwp And Aspt Indices For Evaluation Of Water Quality According To Macroinvertebrates In Değirmendere Stream (Isparta, Turkey), Melek Zeybek, Hasan Kalyoncu, Büşra Karakaş, Seda Özgül
Turkish Journal of Zoology
This study was carried out between March 2011 and February 2012 on Değirmendere Stream in order to determine the water quality of the stream, and to investigate the environmental quality and the applicability of both the Biological Monitoring Working Party (BMWP; Original, Spanish, Hungarian, Czech, and Polish versions) and Average Score Per Taxon (ASPT; Original, Hungarian, and Czech versions) indices. The biotic and diversity indices were applied using the ASTERICS software program. As a result, a total of 59 taxa were detected: 4 taxa from Gastropoda, 1 taxon from Bivalvia, 1 taxon from Oligochaeta, 1 taxon from Hirudinea, 2 taxa …

Evaluation Of Vertical And Horizontal Changes In Community Structure Of Zooplankton In A Deep Dam Lake, Di̇dem Gökçe, Duygu Özhan Turhan
Turkish Journal of Zoology
The purpose of this study was to describe the horizontal and vertical distributions of the zooplankton community structure in Karakaya Dam Lake. Rotifers were numerically dominant (81.89%) in the community during the study period; they were followed by Copepoda (10.32%) and Cladocera (7.79%). In the metalimnetic maximum oxygen zone between 5 and 10 m, cladocerans made up 70.1% of the total number of zooplankton in June and 27.3% of the total number of zooplankton in November. Oxygen values decreased at 10 and 15 m in September and November. While the abundance of rotifers and cladocerans decreased as well, cyclopoids increased …
