Relative contributions of aquaculture-origin and naturally-reproduced grass carp (Ctenopharyngodon idella) in the Laurentian Great Lakes have been unknown. We assessed occurrence distribution wild using ploidy otolith stable oxygen isotope (?18O) data. inferred natal river dispersal from location for microchemistry estimated ages fish to infer years which natural reproduction introductions occu...
Here, we characterized the structure and function of the coagulation factor II (FII) gene in grass carp and determined its role in coagulation mechanisms. The FII gene EST was obtained using a constructed splenic transcriptome database; the full-length FII gene sequence was obtained by 3' and 5' RACE. The open reading frame (ORF) of FII was cloned and the full-length gene was found to be 1718 b...
Hornwort (Ceratophyllum demersum L.) and other aquatic macrophytes have historically been mechanically removed from the Rangiriri drain and Churchill East drain to maintain drain efficiency. As an alternative control method for the high plant biomass that accumulates at the end of summer, the effect of stocking diploid grass carp (Ctenopharyngodon idella L.) on the aquatic vegetation was evalua...
In this experimental series, we studied the swimming capabilities and response of grass carp (Ctenopharyngodon idella) larvae to flow turbulence in a laboratory flume. We compared three different configurations, representing in-stream obstructions commonly found natural streams (e.g., gravel bump, single vertical cylinder, patches submerged rigid vegetation). Grass (postgas bladder emergence) w...
In the present study, genotoxic, histological and hematological effects of water pollution were evaluated in Ctenopharyngodon idella from Ili river. Water fish sampled at three sites. The concentrations following heavy metals measured water: Pb, Co, Mg, Cd, Cu, Zn, Fe. with gradually increased P1 to P3: P1, Cu Fe levels exceeded maximum permissible for culture, P2 – Fe, P3 river, highest freque...
in the present investigation a total of six parasite species, some eye-specific and others non-organ specific parasites were found in the eyes of 48 examined fish species, collected from fresh and brackish waters of iran during 2004-2006. ichthyophthirius multifiliis was isolated from the external surface of the eyes of oncorhynchus mykiss, gyrodactylus stankovici from cyprinus carpio and lern...
Retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) are critical cytosolic sensors that trigger the production of interferons (IFNs). Though their recognition functions are well identified, their unique roles in the downstream signal transduction remain to be elucidated. Herein, we report the differential effect between grass carp (Ctenopharyngodon idell...
Adiponectin plays critical roles in the regulation of energy metabolism mammals. However, its fish remain to be evaluated. In this study, we examined tissue distribution characteristics two adiponectin genes, namely, adipoqa and adipoqb, at transcriptional level, detected changes their mRNA expressions during oral glucose tolerance test (OGTT). Furthermore, prepared recombinant proteins grass c...
