Sturgeons (chondrostean, acipenseridae) are ancient fish species, widely known for their caviar. Nowadays, most of them critically endangered. The sterlet (Acipenser ruthenus) is a common Eurasian sturgeon species with small body size and the fastest reproductive cycle among sturgeons. Such can be used as host surrogate production; application value recovery endangered huge an extremely long cycle. One prerequisite production donor's gametes only to have sterile host. Commonly sterilization...
This study analyses diploid and hydrostatic-pressure-induced triploid brook trout (Salvelinus fontinalis) sampled from a fish farm before (360 days post-hatch, d.p.h.) during the normal time of sexual maturation for pan-sized market (555 667 d.p.h.). Biometric indices slaughtering traits examples both ploidy levels were compared their genomic heterozygosity gonadal development evaluated to assess possible link between these two parameters growth performance. At 555 d.p.h., triploids –...
Assessment of diclofenac LC50 reference values in juvenile and embryonic stages the zebrafish ( Danio rerio ) The aim study was to compare acute toxicity ). Acute tests were performed on aquarium fish , which is one model organisms most commonly used testing. using a semi-static method according OECD guideline No. 203 (Fish, test). Embryo embryos compliance with 212 methodology short-term test embryo sac-fry stages). results subjected probit analysis EKO-TOX 5.2 programme determine 96hLC50...
The aim of this study was to investigate effects subchronic exposure sublethal levels diclofenac on growth, oxidative stress, and histopathological changes in Danio rerio . juvenile growth tests were performed according OECD method number 215. Fish at the age 20 days exposed environmental concentration commonly detected Czech rivers (0.02 mg L −1 ) range concentrations (5, 15, 30, 60 for 28 days. A significant decrease (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Ketoprofen residues have been found in surface water where they present a potential risk to nontarget aquatic species. The aim of this study was assess the impact ketoprofen waters on fish under experimental conditions. Subchronic toxic effects 300 embryos and larvae common carp ( Cyprinus carpio ) were investigated during 30 day toxicity test with concentrations ketoprofen: 0.003, 2.1, 6.3 21 mg/l. exposure showed no effect mortality, but we observed significant delay P < 0.05) hatching...
The aim of this study was to investigate the effects subchronic exposure atrazine on fish growth and development histopathological changes in selected organs (gill, kidney, liver) Danio rerio.Juvenile tests were performed D. rerio according OECD method No. 215.For 28 days, at an initial age 30 days exposed environmental concentration commonly detected Czech rivers (0.3 μg/L) a range sublethal concentrations (3.0, 30.0 90.0 μg/L).The results showed decreasing rates morphological liver...
The authors performed a toxicity test with ciprofloxacin in fertilized eggs of common carp according to guideline 210 the Organisation for Economic Co-operation and Development. tested concentrations were 1 μg L(-1) , 100 500 1000 3000 . Accelerated hatching was found all groups exposed ciprofloxacin, but significant growth reduction only group highest concentration (3000 ). Increased numbers macroscopic morphological anomalies observed on day 6 (after hatching). free embryos larvae (20-23%...
The aim of this study was to assess the impact metribuzin in surface waters on fish under experimental conditions. effects subchronic exposure growth and development histopathological changes selected organs (gill, kidney, liver) activity some biochemical markers (CYP450, EROD) Danio rerio were investigated during a 28-day toxicity test. Juvenile tests performed D. according OECD method number 215. Fish at an initial age 30 days exposed range concentrations (1.5, 5, 16, 33, 53 mg L −1 )....
