Population Growth of Bosmina longirostris Fed Chlorella vulgaris and Scenedesmus subspicatus in Different Densities

In this study, the effects of the different densities of Chlorella vulgaris (0.05 x 106, 0.1 x 106, 0.2 x 106, 0.4 x 106, or 0.8 x 106 cells/ml) and Scenedesmus subspicatus (0.05 x 106, 0.1 x 106, 0.2 x 106, or 0.4 x 106 cells/ml) on culture of the water flea, Bosmina longirostris, were investigated. The experiment was carried out in a photoperiod of 16 h light:8 h dark at 25±1°C. At the beginning of the experiment, one B. longirostris individual (<24 h old) was put into each vessel, and the number of individuals and rate of population increase were determined for 30 days. Increasing the food density increased the number of individuals and the rate of population. The maximum number of B. longirostris individuals (7.1±2.08 ind/ml) and maximum rate of population increase (0.2±0.004/day) was in the group fed 0.2 x 106 cells/ml S. subspicatus. The effect on the number of the individuals was statistically significant (p<0.05)

Current fish fauna of Göksu River (Turkey) and evaluation of its ecological status

Orta Toroslar’daki karst alanlardan beslenen Göksu Irmağı, Doğu Akdeniz Havzası’nın Akdeniz’e dökülen en büyük akarsuyudur. Bu çalışmada, 2014-2017 yılları arasında farklı tarihlerde yapılan örnekleme, gözlem ve literatür taraması ışığında; Göksu Irmağı balık faunasının güncel taksonomik durumu, dağılım alanları, IUCN koruma ölçütleri ve akarsu bölgelerinin ekolojik yapısı değerlendirilmiştir. Çalışmamızda akarsuyun acısu bölgesi hariç 8 familyadan; 7’si yerli, 2’si egzotik ve 2’si göç eden tür (diadrom) olmak üzere toplam 11 tür belirlenmiş olup, bunlardan 6’sı Türkiye için endemiktir. Akarsuyun üst havzasındaki bu yüksek endemizm oranı oldukça dikkat çekicidir. Irmağın ana kollarını oluşturan, yukarı-orta havza drenaj alanı içerisindeki Göksu Çayı ve Ermenek Çayı (Gevne Çayı)’nın üzerinde gerçekleşen karayolu, köprü, baraj ve HES yapımı gibi fiziki tahribatların akarsu ekosisteminin doğal yapısını bozduğu, akarsu yatağında kısmi kurumalar ve habitat parçalanmasına neden olduğu gözlemlenmiştir. Bu baskılar sonucunda, Göksu Çayı ve Gevne Çayı’nın baskın balık türü olan endemik Toros sirazı (Capoeta caelestis) popülasyon yoğunluğunun önemli ölçüde azaldığı tespit edilmiştir. Aynı olumsuz etkenler nedeniyle Gevne Çayı’nın Beyreli Köyü (Hadim-Konya) ile Dumlugöze (Sarıveliler-Karaman) arasında kalan yaklaşık 45 km’lik üst kesiminde 2004-2009 yılları arasında nadiren örneklenen kırmızıbenekli alabalık (Salmo opimus) popülasyonunun yok olduğu belirlenmiştir.The Göksu River, fed by the Central Taurus karst areas, is the largest river of the Eastern Mediterranean Basin flowing into the Mediterranean. In this study, within the scope of the samples and observations we made on different dates between 2014-2017, and in the light of other research findings; the current taxonomic status of the Göksu River fish fauna, distribution areas, IUCN conservation criteria and ecological structure of the river regions were evaluated. In our study, except for the brackish water region of the stream; A total of 11 taxa were identified, belong to 8 families; 7 native (as 6 endemic and 1 widespread), 2 exotic and 2 migratory (diadromous). The high rate of endemism in the upper basins of the river is quite remarkable. There have been physical destructions such as the construction of highways, bridges, dams and HEPPs on Göksu Stream and Ermenek Stream (Gevne Stream) within the upper-middle basin drainage area, which form the main branches of this river. It has been observed that these destructions disrupt the natural structure of the river ecosystem, causing partial drying in the river bed and habitat fragmentation. As a result of these pressures on the stream, it has been determined that the population density of the endemic Taurus scraper (Capoeta caelestis), which is the dominant fish species of Göksu and Gevne streams, has decreased significantly. Due to the same negative factors, it was determined that the red spotted trout (Salmo opimus) population, which was rarely sampled between 2004 and 2009, disappeared in the upper part of the Gevne Stream, approximately 45 km between Beyreli Village (Hadim-Konya) and Dumlugöze (Sarıveliler-Karaman)
