The population genetic structure and historical demography of the flathead mullet Mugil cephalus were investigated using the mtDNA control region (CR) sequences (909-1015 bp) of 126 individuals collected from seven locations in the north-west Pacific between 2005 and 2007. Haplotype diversity (h = 0.9333-1.000) and nucleotide diversity (pi = 0.0046-0.1467) varied greatly among the sampling loca...
Microplastic (MP) ingestion by fish can not only impact the environment but also human health. This study determines abundance and composition (polymer, shape, size) of MPs ingested gray mullet (Mugil cephalus). A total 30 specimens were purchased from local market collected Lake Cernek located in Kızılırmak Delta, Türkiye fishermen. The digestive tracts removed digested with hydrogen peroxide ...
In opposition to toxicology of mammals piscine toxicology is closely connected with the conditions of external environment. The aquatic environment is necessary for embryonic development and after hatching during short or long-lasting larval period of most fish species. An aquatic environment is polluted by many industrial and agricultural wastes. Ammonia as a toxic and common compound in water...
چکیده در این مطالعه تنوع منطقه ای صفات ریخت شناسی، ویژگی های سن، رشد و تولیدمثل ماهی سفید رودخانه ای (leuciscus orientalis) در حوضه جنوبی دریای خزر از فروردین تا خرداد ماه سال 1390 مورد بررسی قرار گرفت. صفات ریخت سنجی قبل از تجزیه و تحلیل به جهت کاهش خطای حاصل از رشد آلومتریک استاندارد شدند. آزمون t نشان داد که تفاوت بارزی در صفات فاصله باله پشتی تا دمی، طول قاعده باله سینه ای و مخرجی، فاصله ب...
صخلملا A total of 48 fresh water fishes, belonging to four species of the family Cyprinidae (Capoeta trutta, Chalcalburnus mossulensis, Cyprinion macrostomum and Leuciscus lepidus) were collected from Darbandikhan lake, southwest Sulaimaniya city, Kurdistan region, in the north of Iraq, from March to the end of July 2008. The inspection of gills revealed the infection of these fishes with four ...
این تحقیق از 15 شهریور ماه سال 1387 تا 15 مرداد ماه 1388 در رودخانه بابلرود (استان مازندران) بر روی ماهی سفید رودخانه ای Leuciscus cephalus)) انجام گرفت. نمونه برداری به صورت ماهانه و با استفاده از دستگاه الکتروشوکر صورت گرفت. در مجموع 441 عدد ماهی سفید رودخانه ای صید گردید. نسبت جنسی نر به ماده، 1 به 41/1 بدست آمد. میانگین طول کل ماهیان سفید رودخانه ای صید شده حدود 81/296/165 میلی متر می باش...
AIM The gray mullet, Mugil cephalus, has been farmed in semi-intensive ponds with tilapia and carps in Egypt for years. The current study used the fluorescent amplified fragment length polymorphism (F-AFLP) technique to search for genetic differences between the populations of M. cephalus in the northern region of Egypt and to detect the gene flow between sampled locations and the homogeneity w...
Bu çalışmada, Köyceğiz Lagünü'ndeki üç kefal balığı türünde balık boyutu ve otolit boyutları arasındaki ilişkiler incelenmiştir. 119 adet Mugil cephalus Linnaeus, 1758, 91 Chelon labrosus (Risso, 1827) 53 saliens 1810) olmak üzere toplam 263 balığının boyu ile sağ sol otolitlerinin boyu, genişliği ölçülmüş ağırlıkları tartılmıştır. Sağ ölçümleri arasında fark istatistiksel olarak önemli bulunma...
Fried Mugil cephalus was investigated under optimal vacuum and atmospheric conditions. The water distribution, texture, color properties of vacuum-fried samples were enhanced compared with atmospheric-fried samples. Meanwhile, frying (VF) reduced the total oil content, protein oxidation, degradation. molecular weight amino acid content suggested that well-preserved during VF. In addition, carbo...
There is intense fishing activity, mainly artisanal, in the Cananéia, Iguape and Ilha Comprida Estuarine System. White mullet (Mugil curema) is one of the local fishery resources and is usually caught with gillnets and fish traps. This study aimed to characterise the Mugil curema fisheries thereby underpinning the management of the species in the region. The study was developed with data collec...
