: The effect of the pyrethroid, bifenthrin, on rainbow trout (Oncorhynchus mykiss) was assessed based biochemical, haematological and histopathological examination fish exposed to Talstar 10 EC pesticide preparation (active substance 100 g/l bifenthrin) at a concentration 14.7 μg/l. There significant (P < 0.01) decrease in plasma ammonia, increase glucose, creatine kinase, alkaline phosphatase lactate dehydrogenase. Haematologically, showed mean erythrocyte volume, haemoglobin, band...
Outbreaks of koi sleepy disease (KSD) caused by carp edema virus (CEV) may seriously affect populations farmed common carp, one the most important fish species for global food production. The present study shows further evidence involvement CEV in outbreaks KSD among and populations: a series infection experiments, from two different genogroups could be transmitted to several strains naïve via cohabitation with infected CEV. In recipient fish, clinical signs were induced. load viral gene...

Genomic selection (GS) is increasingly applied in breeding programmes of major aquaculture species, enabling improved prediction accuracy and genetic gain compared to pedigree-based approaches. Koi Herpesvirus disease (KHVD) notifiable by the World Organisation for Animal Health European Union, causing economic losses carp production. has potential breed with resistance KHVD, thereby contributing control. In current study, Restriction-site Associated DNA sequencing (RAD-seq) was on a...
Cyprinids are the most highly produced group of fishes globally, with common carp being one valuable species group. Koi herpesvirus (KHV) infections can result in high levels mortality, causing major economic losses, and is listed as a notifiable disease by World Organization for Animal Health. Selective breeding host resistance has potential to reduce morbidity losses due KHV. Therefore, improving knowledge about methods incorporating genomic data into may contribute decrease farming. In...
The aim of this study was to assess the effect metribuzin on rainbow trout (Oncorhynchus mykiss). An experimental group fish exposed Sencor 70 WG pesticide product (active substance 70% metribuzin). acute semistatical toxicity test lasting 96 h performed juveniles. 96hLC50 value 89.3 mg/l. examination haematological and biochemical profile histopathological tissue examinations were one- two-year-old after exposure in a concentration showed significantly lower values (P < 0.01) plasma total...
Koi sleepy disease (KSD) is a with increasing importance in global common carp aquaculture. Despite the fact that edema virus (CEV) most likely causative agent of KSD, often presents itself as multifactorial several parasites and bacteria species present on gills, skin or internal organs. Therefore, this study, we analysed presented initial results an interaction flavobacteria CEV development clinical KSD suffering from proliferative gill disease. We examined selected field samples Germany...
Abstract Vaccines represent one of the most promising strategies for mitigating economic losses imposed by infectious diseases to global aquaculture. While majority commercial vaccines employ injection as main route delivery, a substantial body research explores other avenues stimulation protective immunity. Oral vaccines, representing favourable and convenient solution aquaculture industry, have been at forefront scientific interest last couple decades. The orchestrated effort resulted in...
Abstract This work describes the first confirmed cases of carp oedema virus disease (CEVD) in Slovakia and Czech Republic phylogenetic analysis Slovak (CEV) isolates. Four outbreak are described, oldest dating from mid‐May 2013 one case May 2019. In all cases, presence was using nested PCR. PCR products were sequenced compared with 357‐bp nucleotide sequences encoding CEV P4a protein GenBank. four (three common breeding facilities koi garden pond), detected belonged to genogroup I. (koi fish...
This study evaluated efficacy and toxicity of the pyrazinoisoquinoline anthelmintic praziquantel (PZQ) in barbel infected with metacercariae Diplostomum spathaceum adult Pomphorhynchus laevis, assessed antioxidant biomarkers lipid peroxidation response juvenile post-treatment. The estimated 96-hr LC50 PZQ was 28.6 mg/L. For evaluation efficacy, naturally D. were exposed to a 10 20 mg/L 4-day bath treatment. Both concentrations 100% effective against significantly (p < .01) affected activity...
The aim of this study was to assess changes in haematological profile common carp ( Cyprinus carpio ) and rainbow trout Oncorhynchus mykiss after the exposure anaesthetic 2-phenoxyethanol. assessed before, immediately 10 min anaesthesia 24 h with recommended concentration 0.30 ml l -1 10-min 2-phenoxyethanol caused significant increase p < 0.01) haematocrit value relative actual count monocytes anaesthesia. These values returned back normal within hours. In trout, had no effect on...
The damage to fisheries caused by cormorant predation pressure consists of losses due direct and subsequent indirect elicited feeding activities resulting in fish wounding stress. Healed wounds reduce the commercial value afflicted stress may impact body health condition. Fulton´s condition coefficient (FCC) was calculated for wounded healthy two-year old carp originating from five South Moravian (Czech Republic) fishponds. Significant (P = 0.0011) differences FCC (mean ± s.d.), were found...
