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...

Triploidy in grass carp, Ctenopharyngodon idella Valenciennes, 1844, was induced on fertilized eggs to compare cold and heat shocks. Two simplified methods explained for verification of triploidy in grass carp. The cold shock (7 ?C) was given in three treatments for 30 min starting 2.0, 2.5 and 4.0 min after fertilization. In cold shock, the start point (2.0 min after fertilization) showed th...

The present study has carried out to clarify the changes of blood parameters grass carp Ctenopharyngodon idella (Valenciennes, 1844), responding chlorofete effect under laboratory conditions, in presence and absence aquatic plant Ceratophyllum demersum (L.). Three concentrations used during chronic exposure time extended (15days). Blood tests (R. B. Cs., Hb, P.C.V.) were studied for fish expose...

An environment intensively studied from many perspectives, through the efforts of an interdisciplinary team of biologists, ecologists, geneticists, chemists, pedologists, etc. is Moara Domnească agroecosystem. Located in the North-East of Bucharest, the Moara Domnească Lake is used for irrigation of the neighbouring agricultural areas and also for pisciculture (Stavrescu-Bedivan et al., 2011). ...

Peptidoglycan recognition proteins (PGRPs) are pattern recognition molecules of innate immunity. In this study, a long-form PGRP, designated as gcPGRP6, was identified from grass carp Ctenopharyngodon idella. The deduced amino acid sequence of gcPGRP6 is composed of 464 residues with a conserved PGRP domain at the C-terminus. The gcPGRP6 gene consists of four exons and three introns, spacing ap...

The G-protein-coupled receptor GPR84, activated by medium-chain fatty acids, primarily expressed in macrophages and microglia, is involved inflammatory responses retinal development mammals amphibians. However, our understanding of its structure, function, tissue expression, signaling pathways fish limited. In this study, we cloned characterized the coding sequence GPR84 (ciGPR84) grass carp. A...

Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic ...
