The rearing of fish fry in illuminated cages is one of the methods used before fish release into water bodies. The aim of the study was to investigate the peculiarities of infestation with Argulus foliaceus L. of the fry of pike Esox lucius (L.), pike-perch Sander lucioperca (L.), bream Abramis brama (L.), vimba Vimba vimba (L.) and peled Coregonus peled (Gmel.) reared in illuminated cages. The...

A comparative proteomic approach was used to assess the protein expression profile in the liver of 34days old pikeperch larvae fed from day 10 post hatching, with three isoproteic and isolipidic formulated diets varying by their phospholipid (PL) contents (% dry diet weight): 1.4% (PL1), 4.7% (PL5) and 9.5% (PL9). Using 2D-DIGE minimal labelling of liver extracts, we were able to show 56 protei...

Gillnet selectivity is poorly understood for most freshwater fish species, particularly invasive alien species. However, their use to determine mesh could be essential establishing management measures, such as the selective removal of exotic This study aims assess size species in a restored lentic ecosystem. Therefore, we analysed gillnet based on experimental fishing trials performed by using ...

Several causative factors have been proposed for the occurrence of skeletal anomalies in fish larvae, among which we quote nutritional factors, such as LC-PUFAs. This study aimed to investigate effect different dietary DHA and ARA level ratio on pikeperch (Sander lucioperca) larval development performance, digestive capacity, fatty acids composition, skeleton molecular markers oxidative stress ...

The diversity of predatory species plays a key role in ecosystem functioning but our understanding the mechanisms underlying their coexistence is limited, particularly freshwater ecosystems. Northern pike Esox lucius, European perch Perca fluviatilis and pikeperch Sander lucioperca are three widespread lakes, where they often coexist. As potential competitors, we hypothesised that partitioning ...
