The Reproduction Traits of Native Brown Trout Salmo trutta macrostigma T 1954 Turkey

Some key aspects of the reproductive strategy of the brown trout Salmo trutta macrostigma (T., 1954) inhabiting Uzungol stream, Trabzon including spawning season, age at sexual maturity, fecundity and egg size have been studied between January 2009 to May 2010. The ages of the captured fish ranged from 2-8 years. Individuals were composed of 40.85% males and 37.80% females. The present investigation on the fecundity of S.t. macrostigma was carried out to estimate the average and range in the number of ova laid by individual female as well as to study the relationship of the fecundity with total length, total body weight. The mean value of absolute fecundity was 312.23±254.71 (SD) eggs/female. The regression between egg number and fish size (total length and weight) was statistically significant (p<0.05)

Childhood-onset optic neuritis as the first manifestation of Behçet's disease

A 15-year-old girl presented with sudden blurring of vision in both eyes, which was recurring for the third time. The fundoscopy demonstrated bilateral optic disc edema with macular star exudates. The diagnosis of Behçet's disease (BD) could be made 5 months after the first visual disturbance, when the other manifestations of the disease occurred. Although ocular involvement is frequent, primer optic neuritis has rarely been reported in BD. Childhood onset of the disorder is very uncommon as well. To our knowledge, this is the first report of optic neuritis as the first manifestation of BD in the pediatric age group. Copyright © Taylor & Francis Group, LLC

Determination of Bioaccumulation of Heavy Metals and Selenium in Tissues of Brown Trout Salmo trutta macrostigma Duméril 1858 from Munzur Stream Tunceli Turkey

The objective of the present work was to determine the bioaccumulation of arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), uranium (U) and selenium (Se) in gill, liver, and muscle tissues of the fresh water fish Salmo trutta macrostigma (Duméril, 1858) in Munzur Stream, Tunceli, Turkey. The highest concentrations of U (1.83 μg kg−1), Pb (119.84 μg kg−1) and Se (1.31 μg kg−1) were recorded in the gills of S. t. macrostigma. Concentrations of As (46.27 μg kg−1), Cd (109.19 μg kg−1), Hg (16.40 μg kg−1), Cu (18.19 μg kg−1) were recorded at highest levels in the liver. The results showed that there were significant differences in concentrations of As, Cd, Cu, Pb, Se, U and Hg in gill, liver and muscle tissue (p < 0.05). Heavy metals were within the edible parts of the investigated fish were in the permissible safety levels for human uses
