The spermatogenesis of Piaractus mesopotamicus was investigated under light and transmission electron microscopy. The specimens were captured from their natural environment (Rio Miranda and Rio Aquidauana, Pantanal Matogrossense, Brazil) during April and September. The results were compared with the spermatogenic data of specimens under captivity condition. In both conditions, P. mesopotamicus ...
Insight into interplay of some molecular chaperones in a hill stream teleost, Barilius bendelisis under wide seasonal and diurnal thermal fluctuationsSaurabh Dewan,Yashpal Singh,JP Bhatt
This study investigated the occurrence, prevalence, mean abundance and mean intensity of monogenoidean parasites in Piaractus mesopotamicus farmed in cages in the reservoir of the Itaipu Hydroelectric Power Station, Paraná River, Brazil. The parasite distribution pattern and the correlation of prevalence and abundance with the total length of hosts were also investigated. Four monogenoidean spe...
The morphological characteristics of the ventricular myocardium and of coronary vascularization were studied in three freshwater teleost species, Piaractus mesopotamicus, Colossoma macropomum and Clarias gariepinus (African catfish), by correlating their ventricular shapes and swimming habits. In Piaractus mesopotamicus and Colossoma macropomum, species with highly active swimming habits, the c...
The intensive aquaculture needs accurate information on the identification and control of stress situations and/or diseases in order to ensure healthy fishes. The evaluation of blood parameters is the fastest way to detect stress symptoms. In this paper the hematocrit, hemoglobin concentration, mean corpuscular hemoglobin concentration (MCHC), differential count of defense cells (leucocytes and...
Barilius bendelisis is an important food fish and a demanding ornamental species in India. Despite its great economic importance, several wild populations have been suffering drastic reduction. The genetic variability within population is extremely useful for gathering information on individual’s identity, breeding patterns, degree of relatedness and disturbance of genetic variation among them....
با توجه به فقدان اطلاعات در مورد ویژگیهای ریختی و ژنتیکی ماهی کمیاب B. mesopotamicus مطالعهای با هدف فراهم آوردن این اطلاعات برای اولین بار در ایران به اجرا درآمد، به همین سبب در پاییز سال 1391 جمعیتهای ماهیBarilius mesopotamicus از سه اکوسیستم متفاوت در حوضه دجله مورد مطالعه و مقایسه قرار گرفت. برای این منظور نمونههای ماهی از دو رودخانه سیمره، چنگوله و دریاچه سیاه گاو صید و 29 صفت ریخت...
Family Trichodinidae comprises ciliate protozoa distributed worldwide; they are considered some of the main parasitological agents infecting cultivated fish. However, the trichodinidae parasitizing important fish species cultured in Brazil are unknown, and more taxonomic studies on this group of parasites are required. This research morphologically characterizes Trichodina colisae Asmat & Sulta...
11 species of fishes belonging to 8 genera, 4 families and 3 Orders have been recorded. The cyprinids were the most abundant group. contribution total fish collection depicts its highest (96.87 %) in river Barak at Karong. Among cyprinids, Barilius bendelisis Crossocheilus burmanicus depicted bulk abundance (19.35 33.87 % respectively)
