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 ...
Disentangling the role of factors responsible for juvenile fish dispersal is essential to understand ecology individual species, setting corresponding conservation status and evaluating potential risk in case invasion. Because their small body size high sensitivity environmental conditions, movements have largely been explained by external such as wind-induced water currents. In this study, ear...

This study was carried out to evaluate the effects of dietary phospholipid on the development and rearing performance of pikeperch (Sander lucioperca) larvae. From day 10 post-hatching, fish larvae were weaned onto three isoproteic and isolipidic formulated diets with different phospholipid (PL) levels: 1.4 (PL1), 4.7 (PL5) and 9.5% (PL9) of dry matter, as soybean lecithin. Neutral lipid (NL) w...
A 61-day growth experiment was carried out to evaluate the potential of a poultry-based protein (PBP) comprising feather meal (FeM) and poultry meat bone (PMBM), as fishmeal (FM) substitute in diets juvenile pikeperch (Sander lucioperca, L.). Pikeperch (initial body weight 113.12 g) were randomly distributed groups 250 fish twelve 1.8 m3 circular recirculating aquaculture system (RAS) tanks, fe...
