Turkish Journal of Veterinary & Animal Sciences

Reservoirs are unstable environments as a very rapid change from a riverine to lacustrine environment occurs in terms of hydrology, climatology and ecology. These changes have a very significant influence on the growth and reproduction of fish populations. In this study, the effects of different phases of reservoir ontogeny on fish growth in Gelingüllü Dam Lake, a typical Central Anatolian reservoir, were monitored. The growth of mirror carp introduced into Gelingüllü Dam Lake was studied both during an initial phase, from 1995 to 1996, and during a later pre-depression phase, from 1998 to 2000.

An Investigation Of Quality Changes In Anchovy (Engraulis Encrasicolus, L. 1758) Stored At Different Temperatures, Sevi̇m Köse, Mehmet Emi̇n Erdem

Turkish Journal of Veterinary & Animal Sciences

Quality changes in anchovy caught at different times during storage at ambient and refrigerated temperatures were investigated in 3 different batches. Sampling was carried out each day during storage. The results showed no significant differences among the anchovy batches except for bacteriological counts and trimethylamine (TMA) values at refrigerated temperatures. Storage time and temperature had a significant effect (P < 0.001, P < 0.05) on sensory, bacteriological and chemical values. Bacteriological counts and chemical values increased significantly (P < 0.05, P < 0.001) depending on time, while sensory results decreased (P < 0.05). According to sensory results, samples were acceptable for 1 day at ambient temperatures and for 2 days refrigerated. This study showed that refrigeration did not extend the shelf-life of fresh anchovies by more than a day compare to ambient temperature.

Introducing A New Approach To Estimating Red Meat Production In Turkey, Fahri̇ Yavuz, Carl R. Zulauf Jan 2004

Introducing A New Approach To Estimating Red Meat Production In Turkey, Fahri̇ Yavuz, Carl R. Zulauf

Turkish Journal of Veterinary & Animal Sciences

A common concern with official estimates of red meat production in Turkey is that they underestimate the level of production. One of the frequently cited reasons is that unregulated slaughter is undercounted. This study uses an estimation method based on the biology of red meat production to examine the potential impact of this undercounting. The production estimates obtained for 1991-1998 using this biological-based method exceed the numbers estimated by official organizations, but fall within the range of estimates obtained from other proposed approaches to estimating red meat production.

The Use Of Novobiocin And Cefixime-Tellurite In Broth, And Of Cefixime-Tellurite, Salicin, Rhamnose And Mug In Agar Medium For The Detection Of Escherichia Coli O157:H7 In Ground Beef, Murat Gülmez, Ethem Baz, Abamüslüm Güven

Turkish Journal of Veterinary & Animal Sciences

We aimed to improve the selectivity of lauryl tryptose (LST) broth and HC (hemorrhagic colitis Escherichia coli strains) agar for the detection of E. coli O157:H7 in frozen ground beef samples. The selectivity of LST broth was superior to that of LST containing novobiocin (20 mg/l) (LST + n), but LST containing novobiocin, cefixime (0.05 mg/l) and tellurite (2.5 mg/l) (LST + nct) was found to be unsuitable as an enrichment medium. The sorbitol positive strains were significantly more resistant to novobiocin than were the sorbitol negative strains (P < 0.05). As a result, the enrichment of ground beef samples in a selective broth without antibiotics such as LST, and then spread plating a subsequent amount from this original enrichment culture and the first three 10-fold serial dilutions onto a rhamnose and sorbitol based selective medium such as cefixime-tellurite HC medium (CTR-HC) was found to be recommendable as a routine cultural method. Transferring the metallic sheen property of eosin methylene blue (EMB) agar to CTR-HC agar can represent an alternative to the available media, and this will shorten the analysis time by 1 day. Use of salicine or 4-methylumbelliferyl-b-D glucuronide appears unnecessary in routine cultural techniques.
