The Effects of Lead Toxicity on the Hematological Parameters Common Carp (Cyprinus carpio) at Varying Salinity Levels
Background: Lead (Pb) is an important metal used in industries, mining and agriculture. It is equally important to the aquatic ecosystems and has negative impact on the health of aquatic organisms. Methods: The LC50 of lead toxicity at varying salinities was first determined for 96 hours. Then juvenile fish were transferred to tanks individually and were exposed to 0, 15, 30, 60 and 120 mg/l o...
متن کاملIsolation and identification of Legionella spp. from different aquatic sources in south-west of Iran by molecular &culture methods
Legionella pneumophila, the causative agent of Legionnaires’ diseases (LD) is usually transmitted to humans via inhalation of aerosols from contaminated natural and manmade water sources. These organisms may become fatal especially in immunocompromised patients and LD is the one of the important disease from a public health perspective. This survey investigated the frequency of Legionella spp. ...
متن کاملReview Article: An overview of climate change and prevalence of bacterial diseases in salmonid aquaculture
Food fish farming is regarded as one of the most important sectors of the aquaculture industry. Salmon farming is a major contributor to the growth of the aquaculture sector. Climate change is predicted to have a complex impact on aquatic ecosystems, including fisheries and aquaculture. Climate change can cause a fluctuation in water temperature of rivers, lakes, seas, and oceans. This can chan...
متن کاملBackground pathology of the ovary in a laboratory population of zebrafish Danio rerio.
Adult zebrafish Danio rerio originating from one stock used as control animals in a toxicological study were examined histopathologically for the occurrence of spontaneous lesions in the gonads. While no histopathological changes were seen in the testes, the ovaries showed lesions consisting mainly of acute granulomatous inflammation with increased atresia and the presence of egg debris in the ...
متن کاملApplication of single-nucleotide polymorphism (SNP) as a molecular marker in the study of genetic diversity of aquatic populations
Genetic diversity is one of the important and essential characteristics of any population for its survival. The study of genetic variation in different populations of aquatic organisms is of particular importance in order to protect, stabilize and manage their stocks. Based on studies conducted in recent years, molecular markers have proven that they can be used as indicators of the genetic div...
