L. VELKOVA-JORDANOSKA, 2006. Molecular-biological analysis of the parasite Capillaria sp. of the liver of barbel (Barbus meridionalis petenyi Heck.) in Lake Ohrid. Bulg. J. Agric. Sci.,12: 315-319 The analysis of parasites molecular variation has important implications on the taxonomy, phylogenic and population genetics studies. Polymerase chain reaction (PCR) can have significant advantages ov...
The concentrations of Cd, Pb, Ni and Hg were determined in gill, liver and muscle of Barbus xanthopterus in down streams of Karoon and Dez Rivers during summer 2009. Heavy metal concentrations varied significantly, depending on the types of the tissue in fish species. The levels of heavy metals such as Cd, Pb, Ni and Hg in the Barbus xanthopterus of Karoon River were higher than in Barbus xant...
بهعنوان یک اکوسیستم گسترده، تالابها مهیاکننده خدمات اکولوژیکی ارزشمندی هستند. آلودگیهای زیستمحیطی خصوصاً روانابهای ناشی از آفتکشها بایستی در امر حفاظت از سلامت تالاب موردتوجه قرار گیرند. هدف از ارائه این مقاله، ارائه روش واقعگرایانه جهت ارزیابی ریسک اکولوژیکی آفتکشها در تالاب شادگان میباشد. روش واقعگرایانه یا کسر ریسک (RQ)، بهوسیله تعیین غلظت آب و ارزش کل سمیت (TRV) برای 5 آفتکش د...
In this study, the early development of Bunni (Barbus sharpeyi) larvae was surveyed through morphological changes and measuring total length, standard length, head length, thickness of larvae, eye diameter and snout length. The initial period of the larval life can be divided into 2 phases: endogenous and exogenous food sources. During the first three days of the larvae development, there was a...
In a meristic, morphometric and distributional study of Neolissochilus from Peninsular Malaysia, Khaironizam et al. (2015) subsumed Lissochilus tweediei Herre in Herre & Myers 1937 and a taxon they called "Tor soro Bishop 1973" into the synonymy of N. soroides (Duncker 1904) based on data collected from museum specimens. However, "Bishop 1973" is not the correct author citation for Tor soro. In...
