Turkish Journal of Zoology
Mesopotamian spiny eels, Mastacembelus mastacembelus (Banks & Solender, 1794), were collected from a large dam lake located on the Euphrates River in order to determine the most reliable ageing method among different hard structures and to estimate growth parameters. Vertebra, otolith, and opercle series were removed from 195 individuals. Vertebrae displayed the most interpretable annulus formations. Total length ranged from 14.4 cm to 76.9 cm and total weight ranged from 6.0 g to 950.0 g. The length and weight frequency distribution was significantly different between the 2 sexes (K-S test, P < 0.001). The length-weight relationship, determined as W = 0.004TL^{2.84} (r = 0.98), revealed no sex-based significant difference (GLM, P > 0.05). Age classes ranged from 1 to 21 years …

Turkish Journal of Zoology
Age, growth, and reproduction of the large-scaled gurnard were studied in the central Aegean Sea to provide fisheries managers with the essential data for science-based management. A total of 2342 samples were collected by trawl hauls between July 2004 and June 2007 from İzmir Bay (Turkey). The size of the samples ranged from 3.4 to 15.2 cm total length and the samples were composed of 35.2% females, 25.7% males and 39.1% immature individuals, with a female to male ratio of 1:0.73. The length-weight relationship was calculated as W = 0.0086L^{3.16} for all samples. The age composition of the samples was …
Reference Values For Some Haematological, Haematochemical, And Electrophoretic Parameters In The Girgentana Goat, Giuseppe Piccione, Stefania Casella, Lucio Lutri, Irene Vazzana, Vincenzo Ferrantelli, Giovanni Caola
Reference Values For Some Haematological, Haematochemical, And Electrophoretic Parameters In The Girgentana Goat, Giuseppe Piccione, Stefania Casella, Lucio Lutri, Irene Vazzana, Vincenzo Ferrantelli, Giovanni Caola
Turkish Journal of Veterinary & Animal Sciences
The purpose of this study was to determine haematological, haematochemical, and electrophoretic reference values for the Girgentana goat in order to form a basis for clinical interpretation. The study included 348 female Girgentana goats aged from 1 to 6 years. The animals were divided into 3 groups: goats aged 1-2 years (group A), goats aged 3-4 years (group B), and goats aged 5-6 years (group C). Blood samples were collected from each animal every morning at the same time (0800) by means of jugular venipuncture, and red blood cell (RBC), white blood cell (WBC), neutrophil (NEU), lymphocyte (LYM), monocyte (MONO), …
Age, Growth, Length-Weight Relationship And Reproduction Of The Striped Seabream (Lithognathus Mormyrus L., 1758) (Sparidae) In The Beymelek Lagoon (Antalya, Turkey), Yilmaz Emre, İsmet Balik, Çeti̇n Sümer, D. Aytuğ Oskay, H. Özgür Yeşi̇lçi̇men

Turkish Journal of Zoology
Age, growth, length-weight relationship and reproduction were investigated for striped seabream (Lithognathus mormyrus L., 1758) collected from Beymelek Lagoon (Antalya, Turkey) between February 2006 and January 2007. The ages of striped seabream ranged from 0 to 3 years for males and from 0 to 4 years for females. Their total lengths and weights ranged between 14.4 and 26.4 cm and 42 and 297 g for males and 14.3 and 27.4 cm and 40 and 329 g for females, respectively. The growth parameters of the von Bertalanffy equation were: L_{\infinity} = 28.3 cm, K = 0.456 year^{-1} and t_0 = -1.859 …
Protein, Lipid, And Glycogen Levels In The Parasitoid Bracon Hebetor Say (Hymenoptera: Braconidae), Eylem Akman Gündüz, Adem Gülel
Protein, Lipid, And Glycogen Levels In The Parasitoid Bracon Hebetor Say (Hymenoptera: Braconidae), Eylem Akman Gündüz, Adem Gülel
Turkish Journal of Zoology
This study compared the protein, lipid, and glycogen reserves in recently emerged unfed female and male Bracon hebetor Say (Hymenoptera: Braconidae) to those in 5- and 10-day-old wasps fed honey. Galleria mellonella (Linnaeus) (Lepidoptera: Pyralidae) and Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) were used as host species. The mean level of protein in both sexes increased significantly from emergence to day 5, and then returned to emergence levels on day 10 in females, but remained constant in males during the same period. In honey-fed females glycogen levels increased significantly during the first 10 days of life; however, there was no significant …

Turkish Journal of Zoology
Growth and reproduction of the blotched picarel, Spicara maena (Linnaeus, 1758), were determined based on specimens (n = 2547) collected from the central Aegean Sea between July 2004 and June 2007. The samples consisted of 71.9% females, 16.2% males, and 11.9% immature individuals. The sex ratio of females to males was 1:0.23. The length-weight relationship was W = 0.011L^{3.02}, W = 0.011L^{3.00}, and W = 0.011L^{2.99} for the combined sexes, females, and males, respectively. For all samples and both sexes the length-weight relationship showed isometric growth. The von Bertalanffy growth equation was fitted on the basis of mean length-at-age data, …
