Abstract :ÖZET Yaptığımızbu çalımalla, yöremizde Müceldi ve Karasu derelerinde bololarak bulunan tatlı su midyeleri (Unio Sp.) incelenmiştir. Her iki dereye ait 1-7 yaşlı bireylerden oluşan 50'şer adet örnekte, en, boy ve gövde kalınlıkları ortalaması sırasıyla müceidi deresi midyelerinde 2.6610.11 cm, 4.5910.20 cm, l.651O.08 cm Karasu deresi midyelerinde ise 2.92:tO.10 cm, 5.7210.23 cm, 1.84:tO.07 cm olarak bulunmuştur. Canlı ağırlık, et ağırlığı ve et oranı (%) ortalaması ise sırasıyla, Müceldi deresi midyeierinde; 17.29±1.68 g., 3.67iO.30 g., 30.63±1.21, Karasu deresi midyeierinde ise; 22.37±1.78 g., 4.36iO.38 g., 31.44iO.83 olarak bulunmuştur. Ortalama 1 kg kabuklu tatlı su mUJ.yesinden 230 g et elde edilmiştir. Yapılan kimyasal et analizinde ise, % kuru madde, % ham yağ, % ham kül ve % ham protein oranı sırasıyla Müceldi deresi midyelerinde; 13.90,3.02,2.14, 7.60, Karasu deresi midyelerinde ise 13.98,3.03,2.02,8.02 olarak bulun~tur. Bu bulguıara göre; iki dereye ait midyelerin iru;elenen parametreleri arasında sadece boylar arasında önemli farklar görüı~tür. Diğer bütün parametrelerde ise, dereler arasında önemlifarklılıklar gözleTlJ'Tliştir. A STUDY ONE SOME BIOECOLOGICAL TRAITS AND MEAT PRODUCTION OF FRESH WATER MUSSELS (Unio sp. ) COLLECTED FROM THE MÜCELDİAND KARASU STREAMS SUMMARY In this study the mussels collectedfrom the Müceldi and Karasu streams were examined. The average body, length and body thickness were calculated as 2.66:tO.1l cm, 459:tO.20 cm and 1.6510.08 cm in mussel of the Müceldi stream and 2.9210.10 cm, 5.7210.23 cm and 1.84:tO.07 cm in mussul of Karasu stream, respectively. The body weight, meat production and meat ratio (%) were found in mussels of the Müceldi and Karasu streams as 17.29±1.68 g, and 22.37±1.78 g, 3.67±O.30 g and 4.36±O.38 g, 30.63±1.21 % and 31.44iO.83 % respectively. The average meat productionfor 1 kg ofthe live weight of the mussels in two habirats was obtained as 230 g. The dry matter, the crude fat, the cureda ash and the crude protein of the mussels meatfor Müceldi and Karasu streams was alUl1ysed and thefollowing values were obtained: 13.90 % and 13.98 % ,. 3.02 % and 3.03,' % 2.14 and 2.02 %; 7.60 % and 8.02 %, respectively. According to the resuits obtained from this study, the only body lenght for two stream.s was statistically found. BUl the aLi other parameters examined were not found significant.
