The growth hormone secretagogue-receptor (GHS-R) is an endogenous receptor for the gut hormone ghrelin. Here we report the identification and characterization of GHS-R1a in grass carp, Ctenopharyngodon idellus. The full-length GHS-R1a cDNA contained a 1803-bp coding domain sequence which encoded a peptide of 360 amino acid residues. Comparison analysis revealed that the amino acid sequences of ...

Fresh water fish, such as carp (Cyprinus carpio), koi koki (Carassius auratus) and comet auratus have great opportunities for developing aquaculture in Indonesia. However, the presence of argulosis disease caused by ectoparasites Argulus sp. be one obstacles. This parasitic infestation can cause fish to experience a decrease body weight, weakness, bleeding, secondary infection, sale value even ...

Toxicity of Pb(2+) and Cd(2+) is a widespread issue in the world; however, few studies have been conducted to understand their effect at environmentally realistic concentration in a mixture. In the present study, Crucian carp was exposed to Pb(2+) (30 µg·l(-1)), Cd(2+) (100 µg·l(-1)) and their mixture (30+100 µg·l(-1)) for 96 h and 21 d period to assess changes in the liver and muscle vitamin A...

this study was conducted to determine length-weight and length-length relationships, relative condition factor (krel) and fulton?s condition factor (k) for five species including scardinius erythrophtalmus, carassius auratus gibelio, cyprinus carpio, tinca tinca and hemiculter leucisculus belonging to cyprinidae family. fish sampling was carried out by gill net and fyke net in the western regio...

We used flowcytometry to ploidy verification after that investigate difference between diploid and spontaneous triploid through the truss dimension and classical dimension at crucian carp, Carassius auratus, crucian carp C. cuvieri and common carp, Cyprinus carpio collected from Hangang river, Hantangang river, Imjingang river, Geumgang river, Yeongsangang river and Nakdonggang river, Korea. Th...

Intensive agriculture increasingly depends on chemical fertilizers and pesticides. Considerable amounts of these substances persist in the soil and, then, they reach surface water bodies, favouring eutrophication phenomenon or adversely affecting aquatic life. The existence and evolution of aquatic organisms decisively depend on the environment they live in water. This paper presents the result...

Farming and trading of aquarium fish has been considered a popular pastime in the world. Most Iran's are imported from Asian countries including Indonesia, Malaysia, Thailand Vietnam. Fish lice (Argulus) is known as one most important common ectoparasites ornamental fish. Reports indicate that these parasites have observed to Iran (e.g goldfish Carassius auratus koi carp Cyprinus carpio). Today...

This study’s objective was to explore some of the annual Prussian carp’s (Carassius gibelio) biological characteristics (sex ratio, length–weight and gonado somatic index - GSI) in Kopački Rit Nature Park Croatia. The carp is an invasive fish species originated from Asia, which became widely distributed throughout Europe believed be responsible for a decline number indigenous fish, invertebrate...
