Comparison of the growth performance and mortality in Abant Trout (Salmo trutta abanticus Tortonese, 1954) and rainbow trout (Oncorhynchus mykiss Walbaum, 1792) under farming conditions [Çiftlik Koşullarinda Abant Alabaligi (Salmo trutta abanticus Tortonese, 1954) İle Gökkuşagi Alabaligi (Oncorhynchus mykiss Walbaum, 1792)'nin Gelişim Performansi ve Ölüm Oranlarinin Karşilaştirilmasi]

This experiment was conducted between 15th February 2000 (day 1) and 31st January 2001 (day 350) at the DSI-Gölköy Fish Production Station, Bolu (Turkey). Abant trout larvae obtained from eggs of wild Abant trout broodstocks in Lake Abant and rainbow trout larvae obtained from eggs of the hatchery broodstocks in Gölköy Fish Production Station were used. Trials I and II involved eight groups (four Abant and rainbow trout experimental groups, and four Abant and rainbow trout parallel groups). A total of 1784 larvae was used in both the trials. At the end of the experiment, although the mean wet weight of Abant trout was found to be around 5 g, the maximum increase in weight was found in rainbow trout (between 116.202 and 173.315 g in trials I and II). Final mean condition factors (CF) differed between the Abant and the rainbow trout groups (P < 0.001). The specific growth rate (SGR) exhibited significant differences between trials I and II for the Abant and rainbow trout groups (P < 0.01) (P < 0.05). It is concluded that the desired level of growth performance of Abant trout was not obtained in tank conditions. In contrast, the growth and survival rate of rainbow trout were clearly better than those of Abant trout

An overview of molluscan shellfish industry in Turkey

Turkey is surrounded by the Black Sea in the North, by the Aegean Sea in the West, and by the Mediterranean in the South. The length of coastline exceeds 8,000 km. Turkey produces about 625,000 tons of seafood annually. The production of molluscan shellfish has reached 25,000 to 30,000 tons annually. Shellfish, especially bivalvia is not a traditional food in Turkey. Only mussel, Mytilus galloprovincialis is consumed to any significant amount in large cities of western Turkey such as Izmir and Istanbul. Of the 55 million population in Turkey, it is estimated that no more than 1 % consume mussels regularly. Until recently, there was no interest in bivalvia in the domestic market. © 1991 by CRC Press, Inc

Detection of Toxoplasma gondii and Cyclospora cayetanensis in Mytilus galloprovincialis from Izmir Province coast (Turkey) by Real Time PCR/High-Resolution Melting analysis (HRM)

To evaluate the presence of Toxoplasma gondii and Cyclospora cayetanensis in edible shellfish, a total of 795 specimens of Mytilus galloprovincialis from 8 different sites on the west coast of Turkey (Bays of Izmir and Mersin) were examined. Fifty-three pooled samples were created and subjected to EvaGreen (R) RealTime PCR assay and HRM analysis for protozoans detection and oocyst quantification. Seven out of 8 sites were contaminated with at least one protozoan species. Twenty-one out of 53 (39.6%) samples tested positive for T. gondii, C cayetanensis or both pathogens: 26.4% samples positive for C cayetanensis; 9.4% for T. gondii, and 3.8% for both protozoans. The number of oocysts in positive samples ranged from 6 to 30 for T gondii and from 3 to 48 for C cayetanensis. This is the first report of T. gondii Type 1, and C. cayetanensis in M. galloprovincialis, the most consumed shellfish species in Turkey. (C) 2014 Elsevier Ltd. All rights reserved
