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...

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...

Life-history Variation and Age at Maturity in Eurasian Perch (Perca fluviatilis L.)

Heibo, E. 2003. Life-history variation and age at maturity in Eurasian Perch (Perca fluviatilis L.) This thesis deals with life-history variation in perch, with special focus on age at maturity. We conducted field studies to uncover the variation within short geographic distances and a literature review to study variation on a large geographic scale in order to reveal some factors affecting lif...
