Abstract:

In this study, qualitative and quantitative distributions of benthic macroinvertebrates collected monthly from Lake Büyükçekmece were investigated between June 2004 and November 2005. For this purpose 5 different stations were selected for sediment sampling with Ekman dredge. Each sampling includes two subsamples. Furthermore, benthic samples were collected with hand from coast of lake. During sampling, some of the physico-chemical variables such as depth, air and water temperature, dissolved oxygen, pH, salinity, nitrate, nitrit, phosphate, and hardness were measured in situ. Total of 43 taxa in 8 groups were determined. These consisted of 55.32% Chironomidae larvae, 23.03% Oligochaeta and 21.65% other ınvertebrate. Species are 9 Oligochaeta (Psammoryctides albicola, Tubifex tubifex, Limnodrilus hoffmeisteri, L. udekemianus, Limnodrilus sp, Potamothrix hammoniensis, Nais communis, Nais sp., Stylaria lacustris,); 6 Gastropoda (Valvata(Borysthenia) naticina, Galba truncatula, Planorbis planorbis, Physa(Physella) acuta, Lymnea(Radix) peregra, Viviparus viviparus); 3 Bivalvia (Unio pictorum, Anodonta cygnea, Dreissena polymorpha); 6 Ostracoda (Tyrhenocythere amnicola, Candona candida, Physocypria kraepelini, Eucypris sp., Cypridopsis vidua, Prionocypris zenkeri); 1 Mysidacea (Mysis sp.,); 3 Amphipoda (Gammarus sp., Corophium sp., Echinogammarus sp.,); 1 Decapoda (Astacus leptodactylus); 14 Chironomidae (Chironomus plumosus, Chironomus (Comptochironomus) tentans., C. reductus, C. viridicollis, C. anthracimus Cryptotendipes holsatus., Cryptochironomus defectus., Polypedium convictum., Dicrotendipes nervosus, Procladius (Holotanypus) sp., Cladotanytarsus mancus, Tanypus punctipennis, Cryptocladopelma laccophila, Polypedilum aberrans,). Key Words: Büyükçekmece Lake, Distribution of, Benthic Macroinvertebrate.
