Alterations In The Immunological Parameters Of Tench (Tinca Tinca L. 1758) After Acute And Chronic Exposure To Lethal And Sublethal Treatments With Mercury, Cadmium And Lead, Syed Lal Shah, Ahmet Altindağ
Alterations In The Immunological Parameters Of Tench (Tinca Tinca L. 1758) After Acute And Chronic Exposure To Lethal And Sublethal Treatments With Mercury, Cadmium And Lead, Syed Lal Shah, Ahmet Altindağ
Turkish Journal of Veterinary & Animal Sciences
Tinca tinca were exposed to lethal and sublethal treatments with mercury, cadmium and lead for acute and chronic periods to study alterations in immunological parameters. Acute lethal exposure (Lc_{50}/48 h ; 96-h Lc_{50} of Hg 1.0, Cd 6.5, Pb 300 ppm) caused a significant increase in Lct in the Hg treatment and a significant decrease in the Pb treatment, and a significant decrease in total WBC count in the Hg and Cd treatments. Lower acute sublethal exposures (10% Lc50/24 h), caused a significant increase in Lct in the Hg and Pb, treatments and a significant increase in total WBC count …
Effects Of Heavy Metal Accumulation On The 96-H Lc_50 Values In Tench Tinca Tinca L., 1758, Syed Lal Shah, Ahmet Altindağ
Effects Of Heavy Metal Accumulation On The 96-H Lc_50 Values In Tench Tinca Tinca L., 1758, Syed Lal Shah, Ahmet Altindağ
Turkish Journal of Veterinary & Animal Sciences
The effects of already accumulated heavy metals (Hg, Cd, Pb) in the body of tench on the 96-h LC_50 values of the respective heavy metals were studied. The body concentration of mercury, cadmium and lead was 0.011, 0.32 and 1.59 mg/g respectively, and their 96-h LC_50 values were 1.0, 6.5 and 300.0, ppm, respectively. The general accumulation order of heavy metals and their respective 96-h LC_50 values were Hg< Cd< Pb. It was observed that the fish with lowest body concentration of heavy metal showed the lowest 96-h LC_50 value of the respective heavy metal and vice versa. This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC_50 values of the respective heavy metals and the susceptibility of fish.
The Effects Of Ligula Intestinalis Plerocercoids On The Growth Features Of Tench, Tinca Tinca, Mehmet Borga Ergönül, Ahmet Altindağ
The Effects Of Ligula Intestinalis Plerocercoids On The Growth Features Of Tench, Tinca Tinca, Mehmet Borga Ergönül, Ahmet Altindağ
Turkish Journal of Veterinary & Animal Sciences
A total of 272 specimens of tench (Tinca tinca L., 1758) caught in Lake Mogan (Ankara) were examined for the presence of the plerocercoids of Ligula intestinalis, and growth parameters such as age composition, age-length, age-weight and weight-length relationship and condition factor were calculated seperately for both infected and non-infected fish. The only marked difference was observed in value b between infected (2.745) and non-infected (3.014) fish.
The Structure, Mortality And Growth Of The Tench [Tinca Tinca (L., 1758)] Population In Çivril Lake, Denizli, Turkey, Süleyman Balik, Hasan M. Sari, Mustafa Ruşen Ustaoğlu, Ali̇ İlhan
The Structure, Mortality And Growth Of The Tench [Tinca Tinca (L., 1758)] Population In Çivril Lake, Denizli, Turkey, Süleyman Balik, Hasan M. Sari, Mustafa Ruşen Ustaoğlu, Ali̇ İlhan
Turkish Journal of Veterinary & Animal Sciences
The population structure, mortality and growth of the tench [Tinca tinca (L., 1758)] in Çivril Lake was investigated, using 506 fish caught with various gill nets between February 1998 and January 1999. The percentages of females and males in the population were 38.34% and 61.66%, respectively, and the overall female-male sex ratio was 1:1.61. Specimens ranged from 11.4 to 28.8 cm in fork length, and from 27.7 to 420.4 g in weight. The age distribution was I-V in the population. For all individuals, the length-weight relation and von Bertalanffy growth parameters were W = 0.018 L^{3.01}, and L_{\infity} = 33.85 …
Karyotype Analyses Of The Tench (Tinca Tinca L., 1758) Living In Lake Mogan (Ankara), Mustafa Hamalosmanoğlu, Mustafa Kuru
Karyotype Analyses Of The Tench (Tinca Tinca L., 1758) Living In Lake Mogan (Ankara), Mustafa Hamalosmanoğlu, Mustafa Kuru
Turkish Journal of Veterinary & Animal Sciences
Chromosome numbers and structures were investigated in (Tinca tinca L., 1758) of the family Cyprinidae. A solution of 1 ml/100 g of 0.1% colchicine was injected intramuscularly. Four hours later the fish were killed and the kidney and gills were removed and cytogenetic methods were applied. Metaphase chromosomes of the cells in these tissues were investigated numerically and morphologically. It was determined that the fish have 2n = 48 diploid chromosomes made up of 6 pairs of metacentric, 8 pairs of subtelocentric and 10 pairs of acrocentric. The average haploid chromosome length was 2.191 µ. The chromosomes were named and …

The Reproductive Biology Of The Tench (Tinca Tinca L., 1758) In Kayaboğazı (Kütahya, Turkey) Dam Lake, Ali̇ Alaş, Kemal Solak
Turkish Journal of Veterinary & Animal Sciences
This study was carried out between January 1996 and December 1997 in Kayaboğazı Dam Lake. During this period 424 specimens were examined. The age of females and males ranged from I to VII. The fork length and weight of females and males were 102-277 mm and 15-377.02 g and 125-274 mm and 27-369.02 g, respectively. There was no statistically significant difference between females and males in terms of body length and weight.The sex ratio (male:female) was 0.947:1. Gonadosomatic index values varied from 1.40 to 10.19. The sexual maturity age for males and females was III and IV, respectively. The spawning …

Helminth Infections In Tench (Tinca Tinca) From Kapulukaya Dam Lake, Kader Yildiz
Turkish Journal of Veterinary & Animal Sciences
This study was conducted to determine helminth infections in tench (Tinca tinca), caught in Kapulukaya dam lake. The tench were transferred to the laboratory alive or recently dead. Thereafter, they were necropsied. Postmortem examination of the fish revealed that 84% were positive for various helminth species. Asymphylodora tincae (97.6%), Pomphorhynchus laevis (26.1%), metacercariae (15.4%), plerocercoids of Ligula sp. (5.9%) and nematode larvae (2.2%) were detected in infected fish. A. tincae was found in the intestine, P. laevis was found both in the intestine and in the abdominal cavity, plerocercoids of Ligula sp. were found only in the abdominal cavity, while …
