Grass carp, Ctenopharyngodon idella, is the largest freshwater aquaculture fish species worldwide. However, its environmental impacts are increasingly controversial. In this paper, we considered production of a 1500 g commercial grass carp as an example, analyzed through life cycle assessment. The results showed that indicators global warming potential (GWP), acidification potential, eutrophica...

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...

BACKGROUND Praziquantel (PZQ) is an effective pesticide against monogeneans. Its pharmacokinetics in fish may be affected by water environment and temperature. The present study was designed to compare the pharmacokinetics, tissue distribution, and elimination of PZQ in freshwater-acclimated grass carp and brackish water cultured grass carp. Plasma and tissue PZQ concentrations were determined ...

BACKGROUND Fish are vulnerable to stress from over-crowding during transportation and eugenol is the most common sedative used to minimize fish injury. The ADI value of 2.5 mg/kg is recommended by the Joint FAO/WHO Expert Committee on Food Additives. The aim of this work was to study the elimination kinetics of eugenol following exposure of grass carp to a eugenol bath in a simulated transporta...

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...
