“…The results of the identification procedure supported the hypotheses that stripe-patterns in perch remain unchanged through individual growth and are unique enough to allow for a tracking of individuals throughout several weeks long experiments. This agrees with Stolbunov and Pavlov (2006) citing studies by Shaikin (1990) and Zelenetskii and Izyumov (1994) that "the transverse-striped pigmentation does not change throughout life and is inherited". The temporal stability and uniqueness of stripe patterns also in wild-caught fish kept in an outside mesocosm hints at the applicability of this method even under semi-natural conditions.…”

a b s t r a c tIn this study we show that the number, position and shape of stripes were sufficiently unique to demonstrate that juvenile Eurasian perch Perca fluviatilis can be individually identified based on their stripe patterns. The stripe patterns in perch and also other species may thus be used in experiments as an alternative to conventional marking techniques that frequently cause stress to the fish.

“…The macroinvertebrates in perch stomachs were not abundant in terms of biomass estimates (Supplementary Material) or found in roach diet. We largely attribute this to differences in foraging strategy and feeding apparatus morphology, which differ significantly between roach and perch as found by Diehl (1988), Stolbunov and Pavlov (2006), and Peterka and Matěna (2009).…”

Large reductions in fish biomass are common both as a method of managing lake ecosystems by fish removals (biomanipulation), and as naturally occurring fish kills. To further understand how fish reductions change feeding patterns of fish we studied the diets of small‐medium sized roach (Rutilus rutilus) and European perch (Perca fluviatilis) on a monthly basis using gut‐content analysis during an 18‐month period before and following a whole lake fish removal in a eutrophic shallow lake. Further, we performed in‐depth analyses of zoobenthos communities of the profundal and littoral zones, as well as analyzing the zooplankton community in the littoral and pelagic part of the lake to estimate abundance and biomass of potential diet items. We found that, in general, there was a trend towards increased zoobenthivory in both species and among all sized fish after the fish removal, regardless of prior diet preference. Reduced piscivory among larger perch (>150 mm), and reduced zooplanktivory among smaller perch and roach (<150 mm) were also observed. Moreover, during a short period of high zooplankton biomass after the fish removal, both perch and roach (all sizes) shifted their diet towards daphnids, which likely caused a collapse in the daphnid population. We suggest that such change towards periodical zooplanktivory across fish species and size groups may lead to unexpectedly high top‐down control by fish following lake restoration by fish removal.This article is protected by copyright.

Проведено сравнительной морфобиологические анализ сплетни Rutilus rutilus (Linnaeus, 1758), что живет в прибережний и открытым глибоководний зонах оз. Плещеево. Обнаружено, что Прибрежная и пелагическая формы отличаются рядом пластических характеристик, морфофункциональных показникив (величиной ротового открылась, формой тела) i темпом роста. Считается, что Морфофункциональная дифференциация сплетни вызванных Вселенной до озера Дрейсена.
