Sperm 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...
متن کاملThermal sensitivity and phenotypic plasticity of cardiac mitochondrial metabolism in European perch, Perca fluviatilis.
Cellular and mitochondrial metabolic capacity of the heart has been suggested to limit performance of fish at warm temperatures. We investigated this hypothesis by studying the effects of acute temperature increases (16, 23, 30, 32.5 and 36°C) on the thermal sensitivity of 10 key enzymes governing cardiac oxidative and glycolytic metabolism in two populations of European perch (Perca fluviatili...
متن کاملFirst-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 کاملEndoparasites of European perch Perca fluviatilis fry: role of spatial segregation.
A total of 246 perch Perca fluviatilis L. fry, 20 to 106 d old from 3 different reservoir subpopulations (epipelagic perch fry, EPF; bathypelagic perch fry, BPF; littoral perch fry, LPF), were examined for parasites. Six species of endoparasites were found: the nematode Camallanus lacustris was the most common, followed by the cestodes Proteocephalus percae, Bothriocephalus claviceps, Glanitaen...
متن کاملGenetically distinct colour morphs of European perch Perca fluviatilis in Lake Constance differ in susceptibility to macroparasites.
The unusual yellow-finned morph of European perch Perca fluviatilis found in Lake Constance suffers more severely from macroparasite infections, including the tapeworm Triaenophorus nodulosus and the gill worm Ancyrocephalus percae, than conspecifics elsewhere. Microsatellite analysis of yellow-finned P. fluviatilis and red-finned variant recently discovered in Lake Constance revealed significa...
