DOI: 10.1007/s10499-019-00415-0
Abstract: Eurasian perch (Perca fluviatilis) were sampled in April, from May to June and at the end of August to test whether the current season (i.e. feeding conditions) affects the fishes’ stomach size (i.e. volume and… read more here.

DOI: 10.1086/700434
Abstract: The pace-of-life syndrome (POLS) concept predicts that individuals with high baseline metabolic rates demonstrate high boldness, aggressiveness, and activity, especially in food acquisition, with associated relatively greater energy requirements. In fishes, these behaviors may increase… read more here.

DOI: 10.1111/jfb.13285
Abstract: Using the widespread Eurasian perch Perca fluviatilis as a model organism, feeding ranges were investigated using stable-isotope ratios (δ15 N and δ13 C) and body condition. Differences were found between closely located sampling sites in… read more here.

DOI: 10.1111/jzo.12447
Abstract: During the teleost ontogenesis, biotic and abiotic factors influence organs deformations. Despite of an important literature, the potential causes of deformities in fish are still poorly understood. Cultured fish in artificial conditions exhibit higher incidence… read more here.
