First-year overwinter mortality in Eurasian perch (Perca fluviatilis L.)
The importance of overwinter mortality of 0+ perch (Perm fluviatilis L.) in central European lakes was estimated using a stochastic simulation model. The probability of overwinter mortality of a perch co hort was calculated by using a model developed for yellow perch (P. flavescens Mitchill). Winter duration from a long-term data set and the length of perch at the end of the first year from fi...
متن کاملDomestication drive the changes of immune and digestive system of Eurasian perch (Perca fluviatilis)
Domestication has altered a variety of traits within the Eurasian perch (Perca fluviatilis), including phenotypic, physiological and behavioral traits of Eurasian perch (Perca fluviatilis). Little is known, however, about the genetic changes between domesticated and wild Eurasian perch. In this study, we assembled a high-quality de novo reference transcriptome and identified differentially expr...
متن کاملRespiration Rates of Eurasian Perch Perca fluviatilis and Ruffe: Lower Energy Costs in Groups
—The effect of group size on the routine metabolic rate and activity of the two shoaling percids, Eurasian perch Perca fluviatilis and ruffe Gymnocephalus cernuus, was studied by using twin-flow intermittent respirometry and time-lapse video techniques. In both species, we found a clear group effect. In isolated fish, oxygen consumption was as much as twice that in groups of eight fish, with in...
متن کاملSperm characteristics in perch Perca fluviatilis L
Sperm production is a crucial factor for the potential reproductive success of males in many species (Nakatsuru & Kramer, 1982). Especially under strong sperm competition, higher sperm numbers in the ejaculates are likely to increase a male’s chance of fertilization (Parker et al., 1996). But sperm production is limited by physiological constraints, e.g. by testis size, which often depends on t...
