Some Biological Characteristics Of The Tub Gurnard, Chelidonichthys Lucernus (Linnaeus, 1758) In The Sea Of Marmara, Lütfi̇ye Eryilmaz, Nuretti̇n Meri̇ç
Turkish Journal of Veterinary & Animal Sciences
The biology of the tub gurnard, Chelidonichthys lucernus (Linnaeus, 1758), has been studied on data collected between November 1996 and November 1997 from the Sea of Marmara. Totally, 224 tub gurnards were sampled. The age, growth, length-weight relationship, condition factor, male to female ratio, first sexual maturity age, length and reproduction period were examined. The age composition of samples ranged between 1 and 6 years. Total length ranged between 12.3 and 41.5 cm, while weight varied from 15 to 617 g. The total length-weight relationship was estimated as W=0.0092L^{3.019}. The parameters of the von Bertalanffy growth equation were: L_{\infity} = …

Turkish Journal of Veterinary & Animal Sciences
A total of 1096 spotted flounder (Citharus linguatula Linnaeus, 1758) were caught in Edremit Bay from September 1998 to September 2000. Length-weight relationships, age, growth, mortality and sex ratio of the samples were investigated. Within the population of this species, most of the individuals in our samples ranged from 100 to 160 mm (69.63%), the minimum and maximum total lengths of the specimens being 69 and 222 mm, respectively. Positive allometric growth was observed for male, female and all fish. Age distribution of the samples was from I to IV. There was no significant difference between observed and calculated (von …
Age, Growth And Diet Composition Of The Resident Brown Trout, Salmo Trutta Macrostigma Dumeril 1858, In Fırnız Stream Of The River Ceyhan, Turkey, Ahmet Alp, Cemi̇l Kara, Hakan Murat Büyükçapar
Age, Growth And Diet Composition Of The Resident Brown Trout, Salmo Trutta Macrostigma Dumeril 1858, In Fırnız Stream Of The River Ceyhan, Turkey, Ahmet Alp, Cemi̇l Kara, Hakan Murat Büyükçapar
Turkish Journal of Veterinary & Animal Sciences
It was aimed to describe some population charactersitics of Salmo trutta macrostigma from Fırnız Stream of the River Ceyhan. The age, growth, length-weight relationship and diet composition were investigated from May 2000 to February 2001. The ratio of male to female of 197 brown trout caught by electroshocker was 0.67:1.00 and their fork lengths varied from 8.0 to 48.5 cm and the majority of them were in the 11.0-17.0 cm length group. Total weights varied from 7.4 to 1441.0 g and age distribution ranged between 0 and 9. The length-weight relationships were estimated as W = 0.0149*FL^{3.009} (r = 0.994) …
Age, Growth And Condition Of Capoeta Capoeta Angorae Hanko 1924 From The Upper Water Systems Of The River Ceyhan, Turkey, Ahmet Alp, Cemi̇l Kara, H. Murat Büyükçapar, Orhan Bülbül
Age, Growth And Condition Of Capoeta Capoeta Angorae Hanko 1924 From The Upper Water Systems Of The River Ceyhan, Turkey, Ahmet Alp, Cemi̇l Kara, H. Murat Büyükçapar, Orhan Bülbül
Turkish Journal of Veterinary & Animal Sciences
The age, growth and condition factors were described for Capoeta capoeta angorae from the upper parts of the River Ceyhan from May 2000 to February 2001 and the differences in length in the same age group between streams and reservoirs populations were compared. A total of 629 C. c. angorae were examined and the ratio of males to females was estimated as 1.25:1.00. Eleven age groups were recorded from 0+ to 10+ years old and two- and three-year-old fish dominated the sample. The fork lengths (FLs) ranged from 3.1 to 41.5 cm and the majority of the samples were composed …
