Effect of temperature on activities of proteinases in intestinal chyme and mucosa was studied in three fish species (pike perch, zope, roach) belonging to different ecological groups by their nutrition type. There was revealed a significant difference of dependence of enzyme activities in chyme on temperature in the benthophage, roach (a higher level of relative activity in the range of lower t...

Northern pike, Esox Lucius , is one of the most important species for recreational fisheries in Sweden and as a top-predator; it holds an role food web. Despite its ecological socioeconomic significance, pike largely neglected current monitoring programs because seldom caught by conventional methods. As result, there not sufficient data management authorities to employ biologically justified st...

Agriculture, fisheries, and the food industry play a key role in ensuring country's security. The modern fishing Ukraine is highly industrial, capital-intensive, integrated production with high costs, which designed to ensure socio-economic development of many coastal regions provide population valuable protein products necessary for healthy eating. total volume extracted aquatic organisms III ...

Abstract The abundance of pike, a keystone top-predator, have declined dramatically in the Baltic Sea since 1990s likely owing to recruitment failure. It has been proposed that wetland restoration can aid recovery pike stock by increasing number recruits produced anadromous populations. Yet, no previous studies addressed whether restorations are associated with higher abundances adult coastal h...

The aim of the present study was to investigate the content of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in muscle tissues of fish, i.e. carp (Cyprinus carpio, L.), bream (Abramis brama, L.) and pike perch (Stizostedion lucioperca, L.) from the middle Nové Mlýny reservoir and compare our results with previous corresponding studies. Samples were analysed by gas chroma...

Neoplastic transformation of cells has often been associated with changes in cellular oncogenes. While much information has been collected in mammalian systems, relatively little is known about the molecular basis of tumor progression in lower vertebrates. For our studies, tumors were collected from feral northern pike (Esox lucius) from Ostego Lake, MI, where the local population exhibited a 1...

A quantitative real-time PCR (qPCR) based on a standard curve was developed for detection and quantitation of ranaviruses. The target gene for the qPCR was viral DNA polymerase (DNApol). All ten ranavirus isolates studied (Epizootic haematopoietic necrosis virus, EHNV; European catfish virus, ECV; European sheatfish virus, ESV; Frog virus 3, FV3; Bohle iridovirus, BIV; Doctor fish virus, DFV; G...
